[ 1 ] - The Amount of Wear in Attachment of Implant-Supported Overdentures in Mandible
Background and objectives: One of the simplest and cheapest attachments for overdentures, is the ball-type attachment, however, keeping it during the first year of prosthesis delivery and after that is one of the main concerns of dentists. The present study aimed to assess the wear of matrix in overdentures attachment supported by one, two and three implants in the mandible. Materials and metho...
[ 2 ] - Evaluation of Strain Distribution in Bone around Implant in Treatment Design of Overdentures Using Computer and Modeling of Finite Elements
Introduction: Introduction: Few studies have investigated the distribution of stress around implants. In this study the distribution of stress in bones around implants was investigated in five overdenture (OD) treatment designs including OD-1, OD-2, OD-3, OD-4 and OD-5. Materials and methods: The Catia modeling software was used in order to simulate the tooth/implant model and bone. First, the ...
[ 3 ] - Evaluation of the Effect of 2 Flask Investment Materials on Color Stability of 5 Brands of Denture Teeth
Introduction: The purpose of this study was to investigate the effect of flask investment materials on the color changes of different brands of resin denture teeth. Methods: Resin denture teeth (560) were divided into 2 groups according to the materials used for flask investment (silicone or gypsum). All the specimens were thermocycled between 4°C and 60°C with 60-s dwell times for 1,000 cycles...
[ 4 ] - بررسی ارتباط پلی مورفیسم ژن IL-4R با شدت پریودنتیت مزمن
Introduction & Objective: Periodontitis is a multifactorial disease in which host immune system and genetic factors have an important role in its pathogenesis. Genetic polymorphisms in cytokines and their receptors have been proposed as potential markers for periodontal diseases. The aim of the present study was to evaluate whether IL-4R gene polymorphism is associated with chronic periodonti...
