Comprehensive Analysis of Repair/Reinforcement Materials for Polymethyl Methacrylate Denture Bases: Mechanical and Dimensional Stability Characteristics
Medknow - Tập 13 - Trang 439-449 - 2013
R. Venkat, N. Gopichander, M. Vasantakumar
Fracture of complete denture is a common problem as acrylic resins hold inherent limitations. This necessitates affirmation of a selection criterion by evaluating the critical requirements of repair materials. The study intended to evaluate mechanical properties and dimensional stability of common denture base repair and reinforcement materials under standard experimental protocol. Seven types of ... hiện toàn bộ

This survey is undertaken to: (1) assess the perceptions of prosthodontist towards the concept of natural dentition archival (NDA); and (2) to obtain any further suggestions/recommendations regarding it. 616 prosthodontist across India participated in the study. Data was collected using a self- designed, self-administered, pilot tested, structured 10 item questionnaire. Results indicate that 32.1 ... hiện toàn bộ
Comparative Evaluation of Dimensional Accuracy and Tensile Strength of a Type IV Gypsum Using Microwave and Air Drying Methods
Medknow - Tập 13 - Trang 525-530 - 2012
Anuraag Sharma, Manoj Shetty, Chethan Hegde, N. Sridhar Shetty, D. Krishna Prasad
To evaluate dimensional accuracy and tensile strength of a type IV gypsum product, at different time intervals, dried in air or a microwave oven. Eighty specimens prepared from a cylindrical mould were used for measuring tensile strength (group A). Twenty specimens from a master die mould were used for determining dimensional accuracy (group B). In group A, 40 specimens were dried in open air at r... hiện toàn bộ

Rajani A. Dable, Pradnya B. Wasnik, Babita J. Yeshwante, Smita I. Musani, Ashishkumar K. Patil, Sunilkumar N. Nagmode
Dental students using conventional chairs need immediate change in their posture. Implementing an ergonomic posture is necessary as they are at high risk for developing musculoskeletal disorders. This study recommends the use of an ergonomic seat and magnification system to enhance the visibility and the posture of an operator. The aim of this study is to make a foray into the hazards caused by in... hiện toàn bộ
Internal Characterization of Denture Base by Using Acrylic Stains and Tissue Paper
Medknow - Tập 11 - Trang 202-204 - 2011
Seema Pattanaik, Bikash Pattanaik
Characterization of an artificial denture is required to give the denture a more natural appearance. This article describes the laboratory procedures for internal characterization of denture base in a removable prosthesis using acrylic stains and absorbent tissue paper incorporated in the heat cure polymerizing denture base resin at the stage of packing.
Craniofacial Prosthetic Reconstruction Using Polymethyl Methacrylate Implant: A Case Report
Medknow - Tập 14 - Trang 303-307 - 2014
Paul Simon, Jayashree Mohan, Sunantha Selvaraj, B. S. Saravanan, Parikodaiarasan Pari
Large cranial defects of complex geometric shapes are challenging to reconstruct. The cranial implants has to be fabricated prior to the cranioplastic surgery. The ideal material for cranial implant has to be inert, light weight, easy to fit and adaptable to the defect, offering the best aesthetic and functional results. Here is a clinical case report of a patient who was operated for osteomyeliti... hiện toàn bộ
Efficacy of Different Disinfectant Systems on Alginate and Addition Silicone Impression Materials of Indian and International Origin: A Comparative Evaluation
Medknow - Tập 10 - Trang 182-189 - 2011
R. K. Samra, S. V. Bhide
Study was planned to evaluate the efficacy of commonly used disinfectants and to study qualitatively and quantitatively the persistence of microflora on the untreated (control group) and the disinfected impression surface after 24 h. Disinfectant systems used were immersion systems like glutaraldehyde, sodium hypochlorite and the ultraviolet chamber. The effect of disinfectant on most commonly use... hiện toàn bộ
