Abstract

Background: Surgical excision of the maxilla results in communication between the oral cavity, nasal cavity and maxillary sinus. Rehabilitation of such defects involves fabrication of obturator prosthesis by the maxillofacial prosthodontist. Various techniques and materials have been used in the past for rehabilitation of such defects. Aim: To Fabricate a Obturator Prosthesis using Light Cure Wax Pattern. Case Description: A 65-year-old man reported with the chief complaint of inability to chew food due to an ill-fitting prosthesis. His history revealed that patient had undergone maxillectomy of left side due to Carcinoma maxilla 03 years back, followed by the fabrication of a definitive obturator prosthesis. Intraoral examination revealed a well healed Aramany’s Class II post maxillectomy defect on the left side measuring 5 cm X 3.5 cm anteroposteriorly and mediolaterally, with everted margins and irregular borders. This clinical report describes rehabilitation of maxillectomy defect with definitive obturator prosthesis. A light cure wax pattern was used (LiWa®; Willmann & Pein Gmbh) for the fabrication of metal framework. Conclusion: Fabrication of a cast metal framework involves a complex laboratory procedure to achieve the clinical success of the prosthesis. LiWa light curing waxes can be successfully used as an alternative to the conventional wax pattern for the fabrication of cast partial dentures framework for definitive obturators. Clinical Significance: The light cure wax pattern helped in reducing the number of laboratory steps and allowed wax pattern trial in the patient's mouth, saving precious time and ensuring a precise fit of the prosthesis.   Keywords: Maxillectomy, Obturator, Cast Partial Denture, LiWa Pattern, Hollow

Abstract

With the advancing digital technology and introduction of newer biocompatible materials with properties similar to biological tissues, CAD CAM fabricated restorations are gaining wide popularity. Introduction of Zirconia and BioHPP (High Performance Polymer) Polyether-ether-ketone (PEEK) has widened the horizons of clinical prosthodontics. Its use has been successfully demonstrated in implantology for fabrication of frameworks and as substructures for replacement of missing teeth. Literature evidence and clinical reports highlighting their usage for long span FDPs is however scanty. This article aims to highlight a combination of digital-analogue procedure for successful rehabilitation of mutilated and missing anterior teeth in a young adult using virtual articulator, modified Bio-HPP PEEK restorations and manufacturer recommended Visio.lign system. Keywords: Virtual Articulator, BioHPP PEEK, Visiolign.

Abstract

Congenitally missing teeth or hypodontia are conditions which compromise the functional, esthetics and phonetic demands of the patients. Adjunct esthetic treatment procedures like orthodontic space regaining lead to predictable outcomes and create a myriad of available treatment options. This case report is a step-by-step procedure in which congenitally missing maxillary anterior teeth were restored with modern contemporary prosthodontic rehabilitative techniques integrated with adjunctive orthodontics and implantology. Keywords: Adjunct Orthodontics, Hypodontia, Cad-Cam.

Abstract

Bone grafting is a method by which bone deficient areas are built up with the use of different materials, such as autografts, allografts, alloplasts and xenografts. Bone graft materials are placed in different locations for various indications like in alveolar sockets post extraction, to refill a local bony defect due to trauma or infection, to refill a peri-implant defect due to peri-implantitis, for vertical and horizontal augmentation of the mandible and maxilla. Grafts materials acts as a filler and scaffold to help bone formation and promote wound healing. The dental implant therapy demands sufficient bone volume, biologic quality and certain dimensional properties for long term success. In many situations this makes bone grafting necessary along with the dental implant placement. Despite of the advancements in the field of bone graft materials and implants, the perfect bone reconstruction material for dental implant has not yet developed. The aim of this article is to provide a contemporary and comprehensive review of the bone graft materials that can be used in dental implants, discussing their properties, advantages, disadvantages, enlightening the present and the future perspective in the field of bone regeneration. Keywords: Bone graft, Dental implant, Graft material.
