Abstract
Study Design Systematic Review and Meta-Analysis. Objective There has been an increasing trend in maxillofacial injuries associated with combat trauma. Within the maxillofacial complex, the mandible is the most likely structure to be damaged during combat. The structural deficits as a result can be reconstructed with many options. These include vascularised bone grafts (VBGs), non-vascularised bone grafts (NVBGs), alloplastic implants, reconstruction bars and distraction osteogenesis. This study aimed to determine the common modality and efficacy of mandibular reconstruction in combat trauma-related defects. Methods A literature search was conducted on Pubmed, Prospero, Dynamed, DARE, EMBASE, COCHRANE and BMJ databases. Results A total of six articles met the inclusion criteria identifying 165 patients requiring mandibular reconstruction. Non-vascularised iliac bone graft (n = 137) was the most common method followed by ileac crest bone chips harvest using Dacron urethran osteomesh tray (n = 24) and frontoparietal grafts (n = 4). Meta-analysis of five out of six trials demonstrated an overall success rate of 85% (95% CI 79-90; I2 = 59%). A total of 13% (n = 22) of reconstructions failed either completely or partially and 21% (n = 34) of patients suffered postoperative complications. Conclusions NVBGs are a practical, cost-effective and favourable method of war zone management of mandibular defects with success rates comparable to those reported in the civilian literature. However, general trauma principles take precedence to rule out life-threatening injuries. Due consideration of patient factors, surgical factors, and available resources are required in the first-line management of combat-related mandibular defects.

Abstract
Regenerative dentistry is a rapidly evolving field in dentistry, which has been driven by advancements in biomedical engineering research and the rising treatment expectations and demands that exceed the scope of conventional approaches. Tissue engineering, the foundation of regenerative dentistry, mainly focuses on 3 key components: stem cells, bioactive molecules, and scaffolds. Dental tissue-derived stem cells are especially significant in this regard due to their remarkable properties. Regenerative techniques have provided novel approaches to many conventional treatment strategies in various disciplines of dentistry. For instance, regenerative endodontic procedures such as pulp revascularisation have provided an alternative approach to conventional root canal treatment. In addition, conventional surgical and nonsurgical periodontal treatment is being taken over by modified approaches of guided tissue regeneration with the aid of 3-dimensional bioprinting and computer-aided design, which has revolutionised oral and maxillofacial tissue engineering. This review presents a concise overview of the latest treatment strategies that have emerged into clinical practice, potential future technologies, and the role of dental tissue-derived stem cells in regenerative dentistry.

Abstract
Background Although the uncommon dentinogenic ghost cell tumour (DGCT) is a benign entity, it possesses the ability to cause widespread destruction of the jaws and to recur after bone-preserving therapy. Hence, clear margins should be achieved upon surgery, and reconstruction techniques must often be used to restore osseous defects. However, this can be challenging in cases with involvement of the temporomandibular joint (TMJ), and especially in children. Case report We present a case of a DGCT in a 12-year-old boy with wide infiltration of the mandible and the TMJ. A two-staged reconstructive approach was performed. Upon primary surgery, tumour-free margins were obtained and mandibular anatomy was restored using an iliac crest graft and an alloplastic condyle implant for temporary TMJ reconstruction. In a second step 5 months later, having received a customized TMJ prosthesis consisting of a fossa and a condyle component, the TMJ was completely replaced for definitive reconstruction. Conclusion A customized TMJ prosthesis could be a solution for reconstruction of the TMJ in children. However, the further course with respect to growth disturbances must be evaluated upon short-term follow-ups and might require additional corrective interventions.

An Analysis of the Viability of Nonvascular Iliac and Fibula Grafts in Mandibular Reconstruction in Patients with Circulatory Diseases: A Prospective Randomized Study. Indian J Otolaryngol Head Neck Surg 2023; 75:170-177. [PMID: 37007888 PMCID: PMC10050606 DOI: 10.1007/s12070-022-03241-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2022] [Accepted: 10/11/2022] [Indexed: 12/23/2022] Open
Abstract
Vascularized bone grafts are considered as the gold standard for mandibular reconstruction. However, there are certain limitations of them, such as they are contraindicated in patients with circulatory disturbances. Therefore, Non-vascular bone grafts become the viable option for reconstruction. Our study aims to prospectively compare the long-term viability of avascular iliac and fibula bone grafts in the reconstruction of mandibular defects. Objectives were to evaluate the difficulty in swallowing, mastication, speech problems, infection, wound dehiscence, restricted limb movement, and altered gait among the iliac and fibula group. A total of 14 patients, planned for the reconstruction of mandibular defects from 2016 to 2018 were randomly allocated into two groups; nonvascular iliac and fibula graft groups. Clinical assessment for improvement in function, esthetics, wound healing, pain, and donor site morbidity was done and was followed up for one year. Digital orthopantomogram was taken for radiographic evaluation for up to one year. Difficulty in swallowing, mastication, speech, infection, restricted limb movement, and altered gait was statistically significant and was seen more in the fibula group. Wound dehiscence with graft exposure was found in one subject. The overall success rate was 100% in the iliac group and 85.7% in the fibula group. Considering the long-term complications and success rate, the nonvascular iliac graft was found to be superior and can be used as an alternative to a nonvascular fibula graft for a defect length up to 7 cm.

Abstract
Background: Squamous cell carcinoma is the most frequent malignant cancer of the oral cavity. Metastasis involvement is one of the most relevant prognostic factors in terms of survival probability. Patients with oral cancers often undergo extensive en bloc resective surgery of the mandible and maxilla, with or without cervical nodal dissection, based on the presence or occult risk of regional metastases. Several factors affect the choice of flap, to recover aesthetics and function. Case Presentation: The case of a 60-year-old man who underwent maxillectomy with neck dissection as well as a reconstruction with a combination of multiple vascularized free flaps is presented. Conclusions: The excellent integration of the free flaps and the total absence of complications led to a high-quality aesthetic and functional performance of the reconstruction obtained through two different flaps. More specifically, the fibular free flap for bone reconstruction allows a two-team approach and maintains an excellent vascularization, even in case of several osteotomies for the maxillary reconstruction as reported. In addition, the use of free radial forearm flap for soft tissue reconstruction permits to obtain long caliber vessels, thus facilitating surgery without repositioning of the patient during surgery and therefore, consequently reducing surgery times.

Abstract
Background: Cystic lesions of the jaw are commonly found in clinical practice. Large, expansive cysts raise challenges for the clinician from both diagnostic and surgical perspectives. The aim of our work is to present a combined, two-staged surgical approach in histologically confirmed non-aggressive cystic lesions of the jaw. Methods and Results: We report the case of an extensive mandibular cyst, associating a high risk of bone fracture, that is treated in the initial stage by cystic decompression through marsupialization with concomitant histological diagnostic confirmation, followed in the second stage by radical excision and mandibular reconstruction with titanium mesh, with the purpose of prevention for oro-cystic chronic fistula formation. Conclusions: Large odontogenic mandibular cysts imply a meticulously conducted assessment and treatment. Marsupialization should be taken into consideration for the treatment of large cystic lesions, followed by secondary enucleation, with minimal risks for the patient. The soft tissue healing process can be optimized with the use of titanium meshes, as an alternative for other reconstructive techniques, in the management of large cystic lesions.

Abstract
Autologous bone grafting is common in trauma and orthopaedic surgery. Both the Reamer Irrigator Aspirator (RIA) and Iliac Crest Bone Graft (ICBG) aim to obtain autologous bone graft. Although the process of harvesting a bone graft is considered simple, complications may occur. This study examined morbidity and pain at the donor site, blood loss, and iatrogenic fractures, comparing RIA and ICBG. The source of the autologous bone graft, the alternative graft sites, and the storage modalities of the harvested bone marrow were also evaluated. In May 2021, PubMed, Embase, Scopus, and Google Scholar were accessed, with no time constraints. RIA may produce greater blood loss, but with less morbidity and complications, making it a potential alternative source of bone grafting.

Intensive Care as an Independent Risk Factor for Infection after Reconstruction and Augmentation with Autologous Bone Grafts in Craniomaxillofacial Surgery: A Retrospective Cohort Study. J Clin Med 2021; 10:jcm10122560.

Abstract
Autologous bone grafts for reconstruction and augmentation are routinely used for maintaining functionality and facial aesthetics. Associated complications, however, have a significant impact on patients and health care systems. This study aims to investigate the possible risk factors associated with the occurrence of complications in order to provide evidence for the outcome of autologous bone graft reconstructive procedures. Patients from 2008 to 2018 who underwent autologous (mostly mandibular) reconstruction were included in the observational study. Clinical, pathological, and therapeutic factors were examined in univariate and multivariate analysis for significance with occurring complications. A multivariate model was used to create a prognostic model predicting the occurrence of complications. Graft complications requiring revision were exhibited by 33/128 patients. Infections were most frequent, with 4/22 patients affected by multi-resistant germs. Multivariate analysis showed radiotherapy (OR = 5.714; 95% CI: 1.839–17.752; p = 0.003), obstructive pulmonary disease (OPD) (OR = 4.329; 95% CI: 1.040–18.021; p = 0.044) and length of defect (in mm) (OR = 1.016; 95% CI: 1.004–1.028; p = 0.009) as independent risk factors associated with graft complications with high accuracy of prediction (AUC = 0.815). Intensive care (OR = 4.419; 95% CI: 1.576–12.388; p = 0.005) with a coefficient between intensive care and OPD (0.214) being low was identified as the most relevant risk factor for infection. Although intensive care is not a classic risk factor, but rather a summation of factors not reaching significance in the individual case, a stay in ICU (intensive care unit) needs to be considered for graft complications. As a clinical consequence, we recommend using the best possible hygienic measures during procedures e.g., while performing dressing and drainage changes in ICU.

Abstract
Background: Several recent studies have attempted to document VBG and NVBG following mandibular reconstruction, mainly the advantages and disadvantages, but very few have specifically evaluated the differences in large parameters including both radiographic and functional aspects for long-term follow-up. However, the object of this study is to compare between two different methods of reconstruction in mandibular defects and to determine the outcomes of different reconstruction options using autogenous vascularized and nonvascularized bone grafts for mandibular reconstruction.
Patients and Methods: a total of 39 patients, 22 (56.4%) females and 17 (43.6%) males, with a mean age of 36.41 years at the time of presentation (age ranged for 48 years). Study was performed in two stages at the Department of Head and Neck Surgery - Oral and Maxillofacial oncology. In the First stage (N=39), bone-density, bone resorption, and bone graft failure were examined radiographically on panorex and CBCT. The second stage included functional evaluation (physical examination and questionnaire) based on pain, infection, speech and recurrence. Both groups were followed-up for at least 1month, 6 months and 1 year.
Results:the results show significant difference in Pain after one month (p=0.032), radiodensity (p=0.05), bone graft resorption (p=0.03) for 1 year follow-up in favor of the VBG group compared to the NVBG group, there was no statistical difference in bone graft failure, infection, speech and recurrence between the two groups.
Conclusion: Vascularized bone graft is the method of choice, especially in extensive malignant defects. On the other hand, novascularized bone graft (81.2% success rate) is a suitable complementary flap for mandible reconstruction mainly in benign and healthy patients. For future studies, large sample size with long-term follow-up more than 1 year will be required to validate our study.

Abstract
Oral surgery has undergone dramatic developments in recent years due to the use of biomaterials. The aim of the present review is to provide a general overview of the current biomaterials used in oral surgery and to comprehensively outline their impact on post-operative wound healing. A search in Medline was performed, including hand searching. Combinations of searching terms and several criteria were applied for study identification, selection, and inclusion. The literature was searched for reviews published up to July 2020. Reviews evaluating the clinical and histological effects of biomaterials on post-operative wound healing in oral surgical procedures were included. Review selection was performed by two independent reviewers. Disagreements were resolved by a third reviewer, and 41 reviews were included in the final selection. The selected papers covered a wide range of biomaterials such as stem cells, bone grafts, and growth factors. Bioengineering and biomaterials development represent one of the most promising perspectives for the future of oral surgery. In particular, stem cells and growth factors are polarizing the focus of this ever-evolving field, continuously improving standard surgical techniques, and granting access to new approaches.

Titsinides S, Agrogiannis G, Karatzas T. Bone grafting materials in dentoalveolar reconstruction: A comprehensive review. JAPANESE DENTAL SCIENCE REVIEW 2019; 55:26-32. [PMID: 30733842 PMCID: PMC6354279 DOI: 10.1016/j.jdsr.2018.09.003] [Citation(s) in RCA: 99] [Impact Index Per Article: 19.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2018] [Accepted: 09/10/2018] [Indexed: 12/11/2022] Open
Abstract
Bone deficits of the jaws are often attributed to accidents, surgical removal of benign lesions or malignant neoplasms, congenital abnormalities, periodontal inflammation, tooth abscess or extraction and finally jaw atrophy due to advanced age or general disease. These bone defects require rehabilitation for a variety of reasons, e.g. maintaining the normal anatomic outline, eliminating empty space, aesthetic restoration and placing dental implants. Today, several techniques have been developed to eliminate these bone deformities including bone grafting, guided bone regeneration, distraction osteogenesis, use of growth factors and stem cells. Bone grafts consist of materials of natural or synthetic origin, implanted into the bone defect site, documented to possess bone healing properties. Currently, a variety of bone restorative materials with different characteristics are available, possesing different properties. Despite years of effort the 'perfect' bone reconstruction material has not yet been developed, a further effort is required to make this objective feasible. The aim of this article is to provide a contemporary and comprehensive overview of the grafting materials that can be applied in dentoalveolar reconstruction, discussing their properties, advantages and disadvantages, enlightening the present and the future perspectives in the field of bone regeneration.
