Abstract
A 22-year old male was referred to the Department of Oral and Maxillofacial Surgery of a university clinic 2 months after he had sustained multiple traumatic injuries abroad because of an anterior malocclusion. The malocclusion was the sequel of an unrecognised, untreated, already consolidated paramedian mandibular fracture on the right and a fracture of the contralateral mandibular angle on the left. Preoperatively, a cobalt-chrome 3D-printed dental splint was prepared. Surgical correction of the malocclusion was carried out by segmental osteotomies of the mandible at the original fracture sites. This involved a vertical paramedian osteotomy on the right side and a unilateral sagittal split osteotomy on the left mandibular angle side. The mandibular segment was mobilised in the correct occlusion with the aid of the 3D-printed dental splint. The splint was fixed to the teeth with dental composite. The custom made 3D-printed dental splint is considered a promising procedural innovation in oral and maxillofacial surgery.

Abstract
Purpose A high prevalence of obstructive sleep apnea (OSA) is seen in edentulous individuals. Treatment options for edentulous OSA patients however are limited with continuous positive airway pressure therapy (CPAP) remaining the current therapy of choice. As CPAP is associated with high non-adherence rates and oral appliance therapy requiring sufficient dentition, there is a clinical need for effective treatment strategies aimed at edentulous OSA patients. The purpose of this study was to present a thorough overview of the literature regarding (1) the effects of nocturnal denture wearing on OSA, (2) the outcomes of oral appliance therapy, and (3) surgical treatment in edentulous OSA patients. Methods A computer-assisted literature search was performed in the MEDLINE database on “edentulism” and “obstructive sleep apnea.” The search yielded a total of 34 original articles. Results A total of 20 studies were included after exclusion of non-relevant, duplicate, and non-English publications, comprising 4 randomized clinical trials, 12 case reports, and 4 cohort or cross-sectional studies. The outcomes of these studies were addressed in detail concerning nocturnal wearing of dentures, oral appliance therapy, and surgical treatment. Conclusion Currently, there is no consensus in the literature on the effects of nocturnal wearing of dentures on OSA. Several studies report the successful use of oral appliance therapy, including implant-retained mandibular advancement devices (MADs), in selected cases of edentulous patients with varying stages of OSA. Little evidence is available regarding outcomes of surgical procedures in edentulous patients. Based on the results of this literature overview, the paucity of effective evidence-based treatment strategies for edentulous OSA patients indicates the further need of clinical studies to improve clinical management.

Abstract
The continued growth in athletic participation among children and adults has increased the potential incidence of sports-related dental injuries. Regardless of preventive measures, damage and injury to the oral cavity can occur during participation in sports. Luxations, root fractures, bony fractures, and avulsions involving 1 or more teeth are a possibility. Many of these injuries require specific protocols for splinting of the traumatized tooth or teeth to allow the best possible outcomes. This article identifies luxation and avulsion injuries, explains the rationale for splinting, reviews guidelines for splint duration, and discusses contemporary material options available to stabilize affected permanent dentition.

Abstract
The etiology of bruxism is associated with exogenous factors, such as occlusal interference, stress, and anxiety, as well as endogenous factors involving neurotransmitters of the basal ganglia. Due to the multifactorial etiology of bruxism, interdisciplinary treatment involving professionals from different healthcare fields has been proposed. The aim of the present study was to compare 2 groups of patients with bruxism (11 in each group) treated with either an occlusal splint combined with cognitive behavioral therapy or an occlusal splint alone. Surface electromyography of the masseter and anterior temporal muscles at rest was performed before and after treatment. The mean amplitude of activity of all muscles was lower after treatment, except for the right anterior temporal muscle in the group treated with an occlusal splint alone. Mean amplitudes were greater in the anterior temporal muscles than in the masseter muscles. Significantly greater improvement was found in the group exposed to cognitive behavioral therapy (P < 0.05; analysis of variance and Student t tests). Therefore, the combination of occlusal splint and psychological therapy was more effective at achieving muscle relaxation than occlusal splint use alone.

Abstract
Introduction The effects of manipulated dental occlusion on body posture has been investigated quite often and discussed controversially in the literature. Far less attention has been paid to the influence of dental occlusion position on human movement. If human movement was analysed, it was mostly while walking and not while running. This study was therefore designed to identify the effect of lower jaw positions on running behaviour according to different dental occlusion positions. Methods Twenty healthy young recreational runners (mean age = 33.9±5.8 years) participated in this study. Kinematic data were collected using an eight-camera Vicon motion capture system (VICON Motion Systems, Oxford, UK). Subjects were consecutively prepared with four different dental occlusion conditions in random order and performed five running trials per test condition on a level walkway with their preferred running shoes. Vector based pattern recognition methods, in particular cluster analysis and support vector machines (SVM) were used for movement pattern identification. Results Subjects exhibited unique movement patterns leading to 18 clusters for the 20 subjects. No overall classification of the splint condition could be observed. Within individual subjects different running patterns could be identified for the four splint conditions. The splint conditions lead to a more symmetrical running pattern than the control condition. Discussion The influence of an occlusal splint on running pattern can be confirmed in this study. Wearing a splint increases the symmetry of the running pattern. A more symmetrical running pattern might help to reduce the risk of injuries or help in performance. The change of the movement pattern between the neutral condition and any of the three splint conditions was significant within subjects but not across subjects. Therefore the dental splint has a measureable influence on the running pattern of subjects, however subjects individuality has to be considered when choosing the optimal splint condition for a specific subject.

Abstract
Patients are concerned about dental disease and their appearance. Clinicians often must decide not only the type of restoration, but also the type of material for restoration that will provide aesthetics and longevity. A modern practitioner should know the pros and cons of different types of crowns and veneers. They are also responsible to provide treatment for patients with complicated medical histories. Risk assessments include current conditions, risks of recurrence, and suggestions for maintenance of restorations, as well as guidelines to promote the future health and well-being of the patient.

Abstract
Patients are frequently being asked to wear orthodontic retainers for as long as they want their teeth to remain in the post-treatment position. Fixed retainers, which are placed on the lingual surface of anterior teeth only, have the advantage of minimal compliance issues but are not without their problems related to wire fracture, adhesive failure and potential gingival or periodontal disease. Plastic retainers, although associated with relatively good aesthetics and compliance, have limitations related to their physical and mechanical properties. This paper describes a chrome cobalt metal retainer that could be used as a long-term retainer with few drawbacks. The properties of chrome cobalt are described and the clinical procedure is outlined.

Abstract
In this paper, the authors review the rationale and history of mandibular repositioning procedures in relation to temporomandibular disorders (TMDs) as these procedures have evolved over time. A large body of clinical research evidence shows that most TMDs can and should be managed with conservative treatment protocols that do not include any mandibular repositioning procedures. Although this provides a strong clinical argument for avoiding such procedures, very few reports have discussed the biologic reasons for either accepting or rejecting them. This scientific information could provide a basis for determining whether mandibular repositioning procedures can be defended as being medically necessary. This position paper introduces the biologic concept of homeostasis as it applies to this topic. The continuing adaptability of teeth, muscles, and temporomandibular joints throughout life is described in terms of homeostasis, which leads to the conclusion that each person's current temporomandibular joint position is biologically "correct." Therefore, that position does not need to be changed as part of a TMD treatment protocol. This means that irreversible TMD treatment procedures, such as equilibration, orthodontics, full-mouth reconstruction, and orthognathic surgery, cannot be defended as being medically necessary.

Abstract
INTRODUCTION Due to the physical stresses to which they are subjected, military pilots may experience bruxism, an "oral parafunction." Parafunction can cause masticatory muscle suffering and serious dental, periodontal, and temporomandibular joint damage. The aim of this pilot study was to analyze the temperature distribution in masticatory and upper trapezius muscles in a sample of bruxist air force pilots, to evaluate whether an occlusal splint would be able to induce skin temperature variations in the stomatognathic apparatus using the technology of infrared thermography. METHODS A total of 11 male Italian Air Force pilots of high performance aircraft, ages from 27 to 40 yr (mean 34.91 ± 2.15 yr) with 1000-3000 flight hours, were enrolled in the study and analyzed using an infrared camera in order to evaluate the temperature of the masticatory muscles. All the recordings were taken on each subject using the same protocol with and without a temporary occlusal splint. RESULTS The occlusal splint statistically increased each muscle temperature (0.10-0.20°C) on both the sides of the body. No statistically significant differences were found between the left and right muscles (asymmetries) before or after the wearing of the splint except for the anterior temporalis muscle. No significant improvement or variations in temperature symmetry of this muscle was found after the application of the splint. DISCUSSION The use of an occlusal splint could help in increasing muscles temperatures in Air Force pilots with consequent relaxation of their facial muscular system.

Abstract
OBJECTIVE To evaluate the effectiveness of the screw-based intermaxillary traction combined with occlusal splint in the treatment of pediatric mandibular condylar fracture. METHODS Between June 2005 and December 2013, 35 pediatric patients with 49 mandibular condylar fractures were treated, and the clinical data were retrospectively reviewed. There were 25 boys and 10 girls, aged 3-13 years (mean, 7.3 years). The injury causes included falling (18 cases), traffic accident (14 cases), and violence (3 cases). The time between injury and treatment was 2-30 days (mean, 6.8 days). Restricted mouth opening was observed, and the maximal mouth opening was (22.74 +/- 7.22) mm except 3 patients who were too young to measure. Condylar fractures were located at the left (12 cases), at the right (9 cases), at bilateral (14 cases) based on the sites; and fractures were classified as intracapsular (35 fractures), neck (10 fractures), and subcondylar (4 fractures) based on the fracture line. Four self-drilling titanium screws were inserted into the alveolar bone of both maxilla and mandible. After screw inserting, an occlusal splint with a fulcrum was used on the affected side and elastic band was put to perform anterior intermaxillary traction. After 1 month, the screws and splint were removed. Follow-up examinations were carried out on schedule. RESULTS All the patients were followed up from 6 months to 8 years and 10 months (median, 71 months). No screw-related complication occurred in the others except one case of screw loosening. The postoperative maximal mouth opening was (38.82 +/- 2.02) nim. Mild joint noise was found in 4 cases and opening deviation occurred in 6 cases. Radiographic results demonstrated complete condyle remodeling was achieved in 24 cases (32 fractures), and moderate remodeling in 11 cases (17 fractures) at last follow-up. CONCLUSION The screw-based intermaxillary traction combined with occlusal splint might be an effective method for pediatric mandibular condylar fracture. The screw-related complications may be avoided by careful preoperative investigations.

Abstract
There is limited data regarding the benefit of using an occlusal device to help patients resolve a variety of symptoms involving temporomandibular disorder, as well as head, neck, and shoulder pain. The purpose of this study was to evaluate the effect of a carefully adjusted occlusal device on 12 symptoms to determine if there was enough evidence to justify a randomized control trial of this methodology. Splints were designed to ensure a stable, reproducible, mandibular position in a cohort of 157 dental patients with mixed histories of the following 12 symptoms: temporomandibular joint "pop," "click," and lock; jaw, neck, shoulder, and mouth-opening pain; headache; earache; tinnitus; and clenching and grinding of teeth. The results showed significant improvement (P < 0.001) in 11 of the 12 symptoms.

Abstract
OBJECTIVE To analyze the evolution of the thickness, bacterial vitality, covering grade, and the structure after 2 and 4 days of aging in "non-disturbed" plaque-like biofilm (PL-biofilm). METHOD AND MATERIALS Twenty healthy volunteers wore a specific appliance. After 2 days half of the samples were removed from the appliance. Posteriorly, after bacterial vital staining, samples were analyzed using a confocal laser scanning microscope. In the first volunteer, one of the disks was analyzed using a scanning electronic microscope. The same process was realized on the remaining disks after 4 days. RESULTS The thicknesses of the PL-biofilm after 2 and 4 days were not significantly different. The bacterial vitality changed significantly from 72.50 ± 15.50% to 57.54 ± 15.66% over time, which was in contrast to the covering grade (53.08 ± 18.03% and 70.74 ± 19.11%). The structure changed from an irregular surface and compact deepest layer with a high predominance of the coccus shape to a complex structure with voids in the deepest layer and a great proportion of bacillus-shaped bacteria. CONCLUSION The PL-biofilm thickness remained practically constant, decreasing the bacterial vitality and increasing the covering grade over time. Regarding the structure, differences were principally bacterial disposition in the surface and bacterial shape. Clinically, the findings show that new control strategies for combating the oral biofilm should be focused on inhibiting bacterial adhesion to tooth surfaces, which would reduce biofilm formation.

Abstract
PURPOSE To observe the effect of removable denture with metal stent of baked plastic occlusal pad in the reconstruction of dentition defects accompanied with severe residual teeth attrition. METHODS Twenty one patients were selected with dentition defects accompanied with severe residual teeth attrition, who needed occlusal reconstruction. Their removable dentures with metal stent of baked plastic occlusal pad were reconstructed, and their occlusal vertical dimensions were restored. The restoration effect was evaluated. RESULTS Twenty-one patients were treated and followed up for 12-24 months. Excellent results were achieved in 18 patients, and fair results were obtained in 3 patients. CONCLUSIONS Using the baked plastic occlusal pad can not only recover patients' occlusal vertical dimension, but also restore the shapes and function of their residual teeth to a better extent. It is a good method for occlusal reconstruction.

Abstract
The authors tested whether a novel dental gauge that adjusts the mandibular position in both anterior-posterior (A-P) and vertical directions would improve the airway opening. A pilot study of nine patients with sleep breathing disorder used a snoring sound to guide mandibular vertical and protrusion positions with an adjustable mandibular positioning gauge (AMPG). Volumetric airway changes were confirmed by 2-dimensional (2-D) and 3-dimensional (3-D) measurements taken from cone-beam computed tomography (CBCT) scans. Patients experienced a significant average improvement in airway volumetric increase of 50%. The authors concluded that the AMPG device along with employing a snore sound technique as feedback can be used to ensure an improved awake state airway patency and may prove to be a means to optimize fit for oral appliances in treating obstructive sleep apnea.

Abstract
BACKGROUND The latest trends in restorative dentistry are guided both by esthetic and mini-invasive procedures. New ceramic materials, such as lithium disilicate, allow the clinician to obtain invisible restorations with a minimum preparation thickness. SUMMARY A young female patient presented at our practice with left temporomandibular closed locking and uncomfortable occlusal instability. After manual reduction, medical therapy, and reversible treatment with a stabilization splint, a mini-invasive lithium disilicate occlusal inferior posterior rehabilitation was conceived and performed. The esthetic integration of the onlay restorations was excellent, no fractures had occurred by the time of the 1-year follow-up, and the patient perceived the dental occlusion as comfortable. CONCLUSION We strongly believe that a careful approach to esthetics is mandatory nowadays, including in the case of posterior teeth. New ceramic materials and the latest adhesive techniques make it possible to resort to mini-invasive and esthetic approaches, even in cases of restorations that are difficult in terms of functionality.

Abstract
OBJECTIVES A variety of theories on the pathogenesis of temporomandibular disorders (TMD) exists resulting in treatment approaches ranging from the fabrication of occlusal splints to alternative treatment modalities such as osteopathy. The goal of this pilot study was to investigate whether osteopathic treatment causes spatial changes in the maxilla. METHOD AND MATERIALS Following ethics commission approval and informed patient consent, three patients diagnosed with TMD participated in this investigation. In addition to regular treatment, an individualized mandibular occlusal splint was fabricated and a maxillary silicone impression was made. Following osteopathic treatment, the splint was adapted intraorally and another maxillary impression was made. Before and after treatment, the splint and the impressions were scanned three-dimensionally. The resulting images were superimposed using best-fit matching algorithms. RESULTS Inconsistent spatial changes in the posterior areas were observed both in the maxillary impressions as well as in the mandibular splints reaching maximum absolute values of 0.50 mm. CONCLUSION Based on this pilot study, it appears that osteopathic treatment may be capable of inducing spatial changes in the maxilla due to sutural movement thereby validating the fundamental principles of osteopathic treatment. Although, based on the study conducted, it cannot be concluded that osteopathy constitutes a successful treatment alternative in TMD patients, practitioners should be aware of this treatment modality.

Abstract
The ability of surgeons to use advanced techniques can significantly improve both surgical outcome and patient satisfaction. Surgical evolution in mandibular orthognathic surgery is no exception, because advancements have aided both surgical planning and technique. It is important for clinicians to be aware of the historical progression of improvements in this technique and appreciate the technologic advancements as they are happening. Computer-driven surgical planning is becoming increasingly popular, providing surgeons and patients with the ability to adjust to intraoperative and postoperative variations. By using these capabilities, clinicians are now able to give patients the best possible outcomes.

Abstract
Temporomandibular pain has a musculoskeletal origin because it occurs as a consequence of masticatory muscle function disorder and temporomandibular joint disorder. Most common diagnoses of disorders are disc displacement and osteoarthritis, but their comorbidity can also occur. Pain is the most common symptom, where chronic temporomandibular pain may con- tribute to the occurrence of psychological disorders in the patient population. Splint is the most widespread dental method of treatment but other, noninvasive methods of musculoskeletal pain treatment are also recommended. Electronic axiography is used for visualization of mandibular movements, in particular pathologic sounds in the joints. Mental health, although not so obvious in dental practice, can influence the need of a multidisciplinary approach to the patient with disorder of the temporomandibular joint.

Abstract
BACKGROUND Temporomandibular disorders are very common nowadays. One of the methods to treat these problems is occlusal splint therapy. Modern materials should be introduced to this treatment. OBJECTIVES The aim of this paper was to evaluate the properties of light-activated urethane dimethacrylate and the quality of the bonds it creates with thermoforming foils. MATERIAL AND METHODS Thermoforming foils were covered with light-cured resin. A bond was formed between the materials using an adhesive. A coating lacquer was used on the resin as a final preparatory step. Three laboratory tests were run: dye penetrant inspection, a Vickers microhardness test and a linear polymerization shrinkage test. The materials were layered and then cured with a polymerizing lamp emitting light of a wavelength of 400 Nm, according to the manufacturer's instructions. All the occlusal splints were fitted to upper dental arch. The devices had been made in an articulator on specially prepared gypsum models. The results were analyzed statistically using a one-sided binomial test, Spearman's rank-order correlation coefficient and the Friedman ANOVA (p=0.05). RESULTS In the dye penetrant inspection, only one sample out of sixty showed the effects of color penetration to the adhesive connection. The dye only penetrated the layer of lacquer coating the resin. The average value of the Vickers microhardness test with a load of F=50 g applied to the material surface for 30 s was HV0.05=7.43 N/mm2. The average linear shrinkage of the resin observed after polymerization was 1.175%. CONCLUSIONS Light-cured resin and an adhesive connection between the resin and thermoforming foil do not show susceptibility even to strong dye. The maximum polymerization shrinkage occurs immediately after curing. The light-cured resin that was tested seems to be a good alternative method for occlusal splints manufacturing.

Abstract
INTRODUCTION To investigate dentofacial characteristics of orthodontic patients with centric relation (CR)-maximum intercuspation (MI) discrepancy and to analyze changes in dentofacial characteristics between CR and MI positions in these patients using lateral cephalograms. MATERIALS AND METHODS Adult female patients were classified into two groups: large CR-MI discrepancy (greater than 2.0 mm horizontal or vertical mandibular incisor movements during CR to MI change, n = 20) and small CR-MI discrepancy (less than 1.0 mm horizontal and vertical mandibular incisor movements during CR to MI change, n = 22). All subjects underwent temporomandibular joint (TMJ) magnetic resonance imaging prior to treatment. Gnathological stabilizing splints were used to find a reliable CR position in patients with large CR-MI discrepancy. Sixteen variables from lateral cephalograms were analyzed to identify differences in cephalometric variables between CR and MI positions in patients with large discrepancy. Differences in dentofacial cephalometric variables at MI positions between patients with large and small CR-MI discrepancies were also analyzed. RESULTS Patients with large CR-MI discrepancy had backward positioning and rotation of the mandible at the MI position compared to the norm. In addition, the mandible moved more posteriorly and rotated more in a clockwise direction during MI to CR change. Interestingly, all patients with large CR-MI discrepancy had TMJ disk displacement. There were no significant differences in the cephalometric variables of the MI positions between patients with small and large CR-MI discrepancies. CONCLUSIONS This study suggests that adult patients with backward positioning and rotation of the mandible should be carefully evaluated as a result of the potential CR-MI discrepancy.

Abstract
OBJECTIVE To evaluate efficiency of pivot splints in jaw exercises, in combination with stabilization splints, in cases of anterior disc displacement without reduction of temporomandibular joint. SUBJECTS AND METHODS Twenty-three patients who referred to the prosthodontics clinic in 1995-1997 were included in the study, where anterior disc displacement without reduction of temporomandibular joint was diagnosed using magnetic resonance imaging and clinical examination. Pivot splints were used for jaw exercises for five minutes long; five times/day and stabilization splints were used at all other times. The patients were followed for 24 weeks. Lateral and protrusive excursions along with maximum mouth opening and were evaluated at each control. Bilateral palpation of temporal, masseter, sternocleidomastoid muscles and TMJ was assessed for pain perception before and after treatment. Data were statistically analyzed using Paired sample t-test and Independent Samples t-test (p < .05). RESULTS Mean mandibular range of motion measurements increased from 28.74 mm prior to 49.17 mm on maximum opening; right/left lateral excursion from 7.61 mm to 12.04 mm and 4.09 mm to 7.3 mm on protrusion after treatment. All changes observed before and after treatment were found to be statistically significant. (p < .001) Pain symptoms were eliminated at the end of 24 weeks of treatment in all patients. CONCLUSION Using pivot splints as an exercise regimen along with a stabilization splint may be a viable treatment option for patients with anterior disc displacement without reduction; as normal mandibular range of motion was established and pain was eliminated.

Abstract
AIMS To carry out a systematic review and meta-analysis comparing the effects of occlusal splint therapy ("usual treatment") and psychosocial interventions for the treatment of myofascial temporomandibular disorder (TMD) pain in adult patients. METHODS Independent screening and evaluation of randomized clinical trials included comparisons between "usual treatment" based on splint therapy and psychosocial interventions for TMD treatment within electronic databases (PubMed/MEDLINE, CENTRAL, EMBASE), ongoing trials databases (Current Controlled Trials, ClinicalTrials.gov), and additional sources. The outcomes selected for the systematic review were self-reported pain, pain interference, unassisted jaw opening without pain, muscle pain upon palpation, depression, and somatization. The effect measures were analyzed using a random-effect model (Review Manager computer program). RESULTS The outcomes "longterm self-reported pain" and "long-term depression" were significantly different for the comparisons of "usual treatment" and psychosocial interventions, and they favored the latter (P < .005 and P < .05, respectively). These results must be viewed with caution due to the limited number of studies available. A tendency toward greater improvements of psychological outcomes was observed for psychosocial interventions, while physical functioning was slightly more responsive to "usual treatment." CONCLUSION No evidence was found to distinguish the clinical effectiveness between "usual treatment" and psychosocial interventions for myofascial TMD pain. Future studies of TMD and related subdiagnoses should be reported according to core standardized outcomes to facilitate comparisons.

Abstract
OBJECTIVE This study aims to determine whether bruxism and the use of occlusal splints affect the survival of porcelain laminate veneers in patients treated with this technique. MATERIAL AND METHODS Restorations were made in 70 patients, including 30 patients with some type of parafunctional habit. A total of 323 veneers were placed, 170 in patients with bruxism activity, and the remaining 153 in patients without it. A clinical examination determined the presence or absence of ceramic failure (cracks, fractures and debonding) of the restorations; these incidents were analyzed for association with bruxism and the use of splints. RESULTS Analysis of the ceramic failures showed that of the 13 fractures and 29 debonding that were present in our study, 8 fractures and 22 debonding were related to the presence of bruxism. CONCLUSIONS Porcelain laminate veneers are a predictable treatment option that provides excellent results, recognizing a higher risk of failure in patients with bruxism activity. The use of occlusal splints reduces the risk of fractures.

Abstract
PURPOSE This 10-year follow-up prospective study aimed to evaluate the effects of treatment with a mandibular protruding device (MPD) on respiratory parameters and subjective symptoms in patients with obstructive sleep apnea (OSA) or snoring. METHODS Seventy-seven consecutive patients diagnosed with OSA or snoring were treated with an MPD. At baseline and the 10-year follow-up, a polygraphic examination and questionnaires on sleep quality were administrated and weight, and neck size was measured. RESULTS At the 10-year follow-up, we examined 64 of the 77 patients and recorded their current treatment (45 MPD, 9 continuous positive airway pressure (CPAP), and 10 no treatment). For MPD patients, 89 % reported MPD use every night and 9 % several nights a week. Compared to baseline, MPD users with OSA had a significantly decreased oxygen desaturation index (ODI) (p = 0.006) and increased lowest arterial oxygen saturation, SaO2 nadir (p = 0.007) after 10 years. MPD treatment was successful for 70 % of OSA patients, yet 89 % subjectively considered themselves cured, indicating overestimation of the treatment effect. OSA patients who responded to treatment maintained baseline weight and neck size, while these increased for non-responders. Of the baseline snorers still using an MPD, 93 % maintained an ODI value of <5. All CPAP users had an ODI value of <5. Both OSA and snorers using an MPD had significantly fewer self- and relative reports of snoring, apnea, daytime tiredness, and poor night sleep quality (p < 0.001). CONCLUSIONS MPD treatment is well tolerated and effective in a long-term, 10-year perspective. Weight gain may jeopardize MPD effects. Both patients and relatives reported significantly less snoring and fewer periods of apnea.

Abstract
OBJECTIVE To investigate the efficacy of conservative dental treatment (occlusal splint and pharmacologic therapy) and invasive therapy (prosthetic restorations) in the treatment of tension-type headache (TTH). METHOD AND MATERIALS The study sample was composed of 70 patients who presented with symptomatic TTH and were assigned to three treatment groups according to their treatment needs. Group A (30 patients): a conservative treatment protocol with a combination of an occlusal splint and analgesic and muscle relaxant medication. Group B (10 patients): invasive prosthodontic procedures. Group C (30 patients): patients who refused any type of treatment but consented to the study served as a control group. Pain quality was measured with the Headache Impact Test (HIT-6). The statistical analysis was performed with the Wilcoxon rank test (P≤.05). RESULTS Conservative treatment with splints and analgesic medication and invasive treatment by prosthetic rehabilitation relieved the TTH symptoms. The patients who received treatment experienced a significant reduction in their discomfort after 6 months (P≤.01), whereas the patients who refused therapy remained, on average, at the same pain level (P≤.117). In group A, the HIT-6 score was reduced for 26 patients, and in group B for 8 patients. In group C a reduction of HIT-6 scores was observed in 10 patients. CONCLUSION Conservative or invasive occlusal adjustments may serve as a useful tool in the treatment of TTH.

Abstract
Despite the documented excellent clinical performance of dental implants, concerns linger regarding the best way to protect the restored dentition in patients with bruxism. This is because of the risk of occlusal overload that is reported to cause biological and biomechanical failures in the implant-prosthesis system. To better distribute occlusal loads to the rigid components of the prosthesis and to the interface between bone and implant during parafunctional movements, several dentists prescribe acrylic resin occlusal splints for nocturnal use by patients considered at risk. However, it is unclear whether this recommendation is based on scientific evidence or expert clinical opinion. This report reflects our effort to employ the systematic review protocol to assess whether there is scientific evidence to recommend an occlusal splint in bruxers after implant therapy.

Abstract
AIM Occlusal therapy is employed to alleviate the symptoms of a temporomandibular disorder (TMD) at times. However, the long-term effect of occlusal therapy in the masticatory system is not well understood. This case study aims to present a 30-year follow-up of a TMD case. METHODOLOGY The patient developed TMD with intermittent closed lock of the left temporomandibular joint (TMJ). Chief complaints included trismus, pain, and noise of the left TMJ during function. The patient's occlusal disharmony was assessed with use of electronic instruments and corrected based on the neuromuscular concept. A minimum-invasive and reversible approach using adhesive occlusal restorations was used. RESULTS The jaw movement and masticatory muscle activity assessed at the 7- and 23-year follow-ups revealed that the established occlusion was well adapted, and re-established the patient's functional occlusion system. The patient has been free from TMD symptoms with the corrected occlusion for 30 years. CONCLUSIONS Occlusal reconstruction based on the neuromuscular concept can be stably integrated into the patient's functional occlusion system.

Abstract
Several etiologic routes have either been determined or proposed for Temporomandibular Disorders (TMD). Notable among these are myofascial, disc displacement, and arthritides disorders. The absence of concrete and universally accepted evidence-based treatment approaches means that debates as to the precise etiology and treatment of TMDs continue while practitioners attempt to treat and improve the lives of patients who present with these debilitating disorders. The use of oral splints (OS) by clinicians with responsibility to manage TMDs is quite popular, even though its mechanism of action and efficacy remains unclear. This article reviews the rationale for the continued use of OS for the management of TMDs.

Abstract
OBJECTIVES This guideline aims to promote high-quality care by medical specialists for subjects who snore and is designed for everyone involved in the diagnosis and treatment of snoring in an in- or outpatient setting. DISCUSSION To date, a satisfactory definition of snoring is lacking. Snoring is caused by a vibration of soft tissue in the upper airway induced by respiration during sleep. It is triggered by relaxation of the upper airway dilator muscles that occurs during sleep. Multiple risk factors for snoring have been described and snoring is of multifactorial origin. The true incidence of snoring is not clear to date, as the incidence differs throughout literature. Snoring is more likely to appear in middle age, predominantly in males. Diagnostic measures should include a sleep medical history, preferably involving an interview with the bed partner, and may be completed with questionnaires. Clinical examination should include examination of the nose to evaluate the relevant structures for nasal breathing and may be completed with nasal endoscopy. Evaluation of the oropharynx, larynx, and hypopharynx should also be performed. Clinical assessment of the oral cavity should include the size of the tongue, the mucosa of the oral cavity, and the dental status. Furthermore, facial skeletal morphology should be evaluated. In select cases, technical diagnostic measures may be added. Further objective measures should be performed if the medical history and/or clinical examination suggest sleep-disordered breathing, if relevant comorbidities are present, and if the subject requests treatment for snoring. According to current knowledge, snoring is not associated with medical hazard, and generally, there is no medical indication for treatment. Weight reduction should be achieved in every overweight subject who snores. In snorers who snore only in the supine position, positional treatment can be considered. In suitable cases, snoring can be treated successfully with intraoral devices. Minimally invasive surgery of the soft palate can be considered as long as the individual anatomy appears suitable. Treatment selection should be based on individual anatomic findings. After a therapeutic intervention, follow-up visits should take place after an appropriate time frame to assess treatment success and to potentially indicate further intervention.

Abstract
BACKGROUND The use of a Tanner type stabilization splint, fabricated on a leaf gauge articulation for the treatment of patients with disc displacement without reduction, is lacking in the literature. OBJECTIVES The purpose of the study is to collect non-controlled, therapy-related observations; in other words, to demonstrate the efficacy of this appliance for the treatment of patients with disc displacement without reduction. METHODS The study enrolled 55 patients, 5 men, and 50 women, with the clinical diagnosis disc displacement without reduction, 42 with and 13 without limited mouth opening. All patients received a splint in the musculoskeletally stable centric relation (CR) position. Mouth opening, clinical performance, and the timeframe of splint treatment were assessed. RESULTS For 37 patients with a disc displacement without reduction with limited opening, the largest increase in mouth opening (9.5 +/- 5.6 mm) occurred in the first week (7.9 +/- 2.5 days). No occlusal adjustment of the splint was needed during the treatment sequence. For three patients, treatment took up to 3 months (8.1%), for 13 patients, between 3 and 6 months (35.1%), and for 17 patients, within a year (45.9%), making a total of 89.1% successfully treated patients. Out of 50 patients, 29 had a total resolution of signs and symptoms, whereas 21 patients still suffered from solitary temporomandibular disorder (TMD) signs. CONCLUSION A Tanner type stabilization splint, fabricated in the musculoskeletally stable CR position, appears to be an effective and efficient means for the treatment of patients with disc displacement without reduction. Its efficacy makes it eligible to be tested in a randomized controlled trial. CLINICAL IMPLICATIONS The efficacy of this specific splint, fabricated in the musculoskeletally stable CR position, makes it a promising tool to treat TMD patients with disc displacement without reduction.

Abstract
INTRODUCTION Mandibular fractures are relatively less frequent in children when compared to adults. Pediatric patients present a unique challenge to maxillofacial surgeons in terms of their treatment planning and in their functional needs. We currently describe our experience with lateral compression open cap splint with circummandibular wiring as a treatment modality which involves fewer risks in treating pediatric symphysis/parasymphysis/body mandibular fractures. MATERIALS AND METHODS A retrospective analysis of pediatric patients with mandibular symphysis/parasymphysis/body fractures operated from January 2007 to January 2012 was performed. Clinical photographs and orthopantomogram assessment at the time of presentation, after treatment, and at 6 months postoperatively were evaluated. RESULTS All the 10 patients were followed up until the period of 6 months, and none of them had any major complications. Postoperatively, there was satisfactory healing and union of fracture fragments in all the patients. Only one patient developed infection at submental region. The 6-month follow-up showed good occlusion, without interference in teeth eruption and no signs of temporomandibular joint problems. CONCLUSIONS Lateral compression open cap splints for treatment of pediatric mandibular symphysis/parasymphysis/body fractures are reliable treatment modalities with regard to occlusion-guided fracture reduction.

Abstract
Osteoarthrosis is a disease that affects the temporomandibular joint (TMJ). This case report chronicles the diagnosis and treatment of a patient for whom this pathological condition was accompanied by a rupture of the articular disc. The patient presented with loud sounds in the left TMJ and an irregular mandibular occlusal plane due to condylar intrusion in the glenoid fossa on the ipsilateral side. A noninvasive treatment was selected. A 4-month follow-up revealed remission of the articular sounds, and tissue regeneration was noted. These improvements remained visible at 5-year follow-up.

Abstract
The aim of the study was to evaluate changes in pain intensity and self-perceived quality of life in patients with temporomandibular disorders (TMD) during stabilization splint therapy. The hypothesis was that the clinical subtype of TMD, depending on whether pain is of muscular or temporomandibular joint origin, and pain chronicity (acute vs. chronic pain) differently affect treatment response. Thirty patients were included and treated with a stabilization splint in a 6-month clinical trial. Treatment outcomes included pain-free maximal mouth opening (MO), assisted maximal MO, path of MO, asymmetry in lateral excursions, spontaneous pain intensity (visual analog scale, VAS), and self-perceived quality of life (Oral Health Impact Profile, OHIP-14). Overall, VAS and OHIP-14 scores changed significantly over time (VAS: F = 80.85, p < 0.001; OHIP-14: F = 34.78, p < 0.001). After 6 months, changes in pain intensity did not differ significantly between myofascial pain (MP) and disc displacement (DD) groups (F = 0.497, p = 0.685, effect size = 0.018), or between acute pain (AP) and chronic pain (CP) patients (F = 1.856, p = 0.144, effect size = 0.064). Changes in self-perceived quality of life did not differ significantly between MP and DD groups (F = 0.213, p = 0.847, effect size = 0.008), or between AP and CP patients (F = 0.816, p = 0.489, effect size = 0.029). Linear regression analysis was used to assess the contribution of each predictor variable to the explanation of the OHIP summary score variance. Results showed pain reduction (coefficient = 0.303; 95% CI: 0.120 to 0.485) and MO increase (coefficient = 0.149; 95% CI: 0.037 to 0.260) to be independent predictors of the OHIP-14 summary score changes (R2 = 0.453), whereas other variables did not affect treatment outcome as assessed by OHIP-14. In conclusion, during 6-month stabilization splint therapy, significant changes in VAS and OHIP-14 summary scores were found. However, there were no significant differences in improvement rates between subjects with acute and chronic pain. Furthermore, no significant differences in improvement rates were found depending on whether pain was of muscular or temporomandibular joint origin.

Abstract
This study was designed to evaluate masticatory performance in bruxist patients. The experimental group was composed of 16 dentate volunteers presenting with bruxism and treated by interocclusal appliances and a control group, consisting of 16 dentate volunteers with no symptoms of bruxism. To evaluate masticatory performance, the volunteers chewed .03 grams of peanuts contained in polyvinyl wrapper for four and twelve masticatory cycles. The number of chewed particles was counted using an optical scanning method by Image-Pro Plus 1.4 software (Media Cybernetics, Inc., Silverspring, MD). The score was expressed as the mean of the number of chewed particles for each wrapper. Masticatory performance evaluations were carried out in a single period for the control group and for the experimental group, before interocclusal appliance insertion, and after seven, 15, 30, and 60 days. Comparison between groups, as well as between before and after interocclusal appliance insertion, showed no significant differences (P>.05), irrespective of the number of masticatory cycles.
