Preserving esthetics, occlusion and occlusal vertical dimension in a patient with fixed prostheses seeking dental implant treatment

Evaluation of complacency about dental implants with shared decision making and satisfaction scores: A cross-sectional study

Background

The dentist-patient relationship is delicate. Engaging the patient in the dental treatment planning especially for lengthy procedures as dental implants improves the relation as well as treatment outcomes including patient satisfaction. We aimed at evaluating the importance of Shared Decision making (SDM) and level of satisfaction among dental implant patients by employing SDM and satisfaction scores.

Materials & Methods

The present cross-sectional study was pursued between April 2019 to September 2019, among dental implant patients (n = 144) who have completed their prosthetic part of implant treatment with at least 3 months of post-restoration evaluation. Demographic and implant data were collected from electronic filing system (Salud) as well as measurement of SDM score. Data were analyzed using SPSS 24.0 version statistical software.

Results

The mean satisfaction score was higher for implant placement with Periodontists (31.9%). However, among surgical specialist the mean satisfaction score was found to be higher for oral surgeons who had 1–5 years of experience (46.5%). Patients reported that their decision making was greatly influenced by the treating dentist. A statistical significance was found where (64.6%) of Implant patients would like to undergo the procedure again (p < 0.0001).

Conclusion

Shared decision-making and patient satisfaction enables the treatment delivery to be more effective and ethical, in addition to being patient-centered care.

Prosthodontic Applications of Polymethyl Methacrylate (PMMA): An Update

A wide range of polymers are commonly used for various applications in prosthodontics. Polymethyl methacrylate (PMMA) is commonly used for prosthetic dental applications, including the fabrication of artificial teeth, denture bases, dentures, obturators, orthodontic retainers, temporary or provisional crowns, and for the repair of dental prostheses. Additional dental applications of PMMA include occlusal splints, printed or milled casts, dies for treatment planning, and the embedding of tooth specimens for research purposes. The unique properties of PMMA, such as its low density, aesthetics, cost-effectiveness, ease of manipulation, and tailorable physical and mechanical properties, make it a suitable and popular biomaterial for these dental applications. To further improve the properties (thermal properties, water sorption, solubility, impact strength, flexural strength) of PMMA, several chemical modifications and mechanical reinforcement techniques using various types of fibers, nanoparticles, and nanotubes have been reported recently. The present article comprehensively reviews various aspects and properties of PMMA biomaterials, mainly for prosthodontic applications. In addition, recent updates and modifications to enhance the physical and mechanical properties of PMMA are also discussed.

An Anthropometric Study of Cranio-Facial Measurements and Their Correlation with Vertical Dimension of Occlusion among Saudi Arabian Subpopulations

BACKGROUND

Determining and restoring physiological vertical dimension of occlusion (VDO) is the critical step during complete mouth rehabilitation. The improper VDO compromises the aesthetics, phonetics and functional efficiency of the prosthesis. Various methods are suggested to determine the accurate VDO, including the facial measurements in the clinical situations with no pre-extraction records. The generalisation of correlation between the facial measurements to VDO is criticised due to gender dimorphism and racial differences. Hence, it is prudent to verify the hypothesis of facial proportion and correlation of lower third of the face to remaining craniofacial measurements in different ethnic groups. The objective of the study was to evaluate the correlation of craniofacial measurements and OVD in the Saudi-Arabian ethnic group.

METHODOLOGY

Total of 228 participants from Saudi-Arabian Ethnic group were randomly recruited in this cross-sectional study. Fifteen craniofacial measurements were recorded with modified digital Vernier callipers, and OVD was recorded at centric occlusion. The obtained data were analysed by using the Spearman's correlation and linear regression analysis.

RESULTS

The Mean OVD in male participants was higher (69.25 ± 5.54) in comparison to female participants (57.41 ± 5.32). The craniofacial measurement of Exocanthion-right labial commissure and the Mesial wall of the right external auditory canal-orbitale lateral had a strong positive correlation with VDO. The strong correlation was recorded with a trichion-upper border of right eyebrow line and trichion-Nasion only in males. Meanwhile, the length of an auricle recorded the positive correlation in female participants.

CONCLUSIONS

Being simple and non-invasive technique, craniofacial measurements and linear equations could be routinely utilised to determine VDO.
