Facial disfigurement affects the functional, social and psychological well-being of an individual. It reduces an individual’s self esteem and acceptance in the society. It can be congenital or acquired. Prosthetic rehabilitation and surgical reconstruction techniques are the ways to lessen or diminish the problems associated with facial disfigurement. Prosthetic rehabilitation is favored as it is less invasive and affordable. The success of a prosthetic rehabilitation of any part relies on the availability of a method of attaching the artificial substitute securely to its place. Various means of retention have been developed over the years from metal bands to implants. With the advancing technology, in cases where anatomic undercuts are futile, craniofacial implants prove to be a boon for rehabilitation. In this literature review, the various modes of retention available for maxillofacial prostheses were assessed and appraised.

The balance and symmetry of mandibular function gets destroyed by the loss of continuity of the mandible, which deviates the residual fragment towards the resected side thereby altering the mandibular movements. Physical therapy in combination with prosthodontic treatment can be used to reduce the mandibular deviation and hence it improves the masticatory efficiency. Many prosthetic methods are discovered to minimize deviation and provide masticatory efficiency. Some of these methods are mandibular guide flange prosthesis, implant supported prosthesis and palatal guidance restoration. Contact of Tongue with palate is important for the production of normal speech, also the proper place of the tongue during certain sounds is important. In partial glossectomy conditions, tongue to palate articulation gets affected during speech and patient faces difficulty to pronounce certain sounds. For the rehabilitation of such patient thorough knowledge of the production of different sounds can be useful for diagnosis and treatment planning.

Aim - The aim of this study was to evaluate and compare the peri-implant strain transmitted through splinted and non-splinted prostheses cemented on implants of two different lengths (8mm and 11.5mm) when subjected to an axial load. Method – The study was conducted on two polypropylene models on which implants of 8mm and 11.5mm length were placed in the molar region. Splinted and non-splinted prostheses were cemented to the implant abutments placed on the implants. Metal jig simulating the anatomy of the opposing tooth was casted and adapted to the prostheses. An axial load of 400N was applied to the assembly using Universal testing machine. The peri implant strain transmitted through these prostheses was recorded using strain gauges attached to Wheatstone bridge circuit. RESULT – The observations showed that implant length and splinting of the prostheses, both significantly affect the peri implant strain as analysed by one way ANOVA statistical test. [F(3,36) = 1882.81 P<0.05]. Lowest peri implant strain was observed in splinted prosthesis cemented on implant with 11.5mm length followed by non-splinted prosthesis on 11.5mm length implant followed by splinted prosthesis on 8mm length implant followed by non-splinted prosthesis on 8mm length implant.

Purpose: The inter-disciplinary approach to practise and also should constantly update their knowledge to keep up with the demands that this field presents. Aim: The aim of this study was to evaluate the knowledge, attitude and practice of Esthetic dentistry amongst the practicing dentists of private dental colleges in Navi Mumbai, through a questionnaire- based study. Materials and Methods: Self-administered KAP (Knowledge, Attitude, Practise) questionnaires were distributed amongst the practicing dentists of private dental colleges in Navi Mumbai. A total of 100 questionnaires were distributed. Statistical analysis used: Pearson’s chi. Sq. test was applied and the likelihood ratio calculated for each question. Independent T Test was applied for equality of means between the groups, i.e. both gender and graduate and post graduate qualifications. Results: Most of the dentists were aware of the field and practise of Esthetic dentistry, although there were some differences found between the general dentists and specialists in adopting and accepting new dental procedures.  According to them, Finances played a major role in opting for an esthetic treatment by patients.   Conclusion: With the advances in esthetic dentistry and increased level of patients’ expectations and awareness, practicing dentists should be well versed with the same, by attending continuing dental education programs and courses to update their skill and knowledge. Also Finances plays a major role in opting for an esthetic treatment.
