Aim: To compare the effects of cast partial denture with conventional all acrylic denture in respect to retention, stability, masticatory efficiency, comfort and periodontal health of abutments. Methods: 50 adult partially edentulous patient seeking for replacement of missing teeth having Kennedy class I and II arches with or without modification areas were selected for the study. Group-A was t...

The debonding of acrylic resin teeth with the denture base resin has been related to several different factors of which contamination of the bonding surfaces with wax has been suggested as the major cause. The purpose of this study was to determine the efficient method of wax removal from denture teeth using hot water at different temperatures ranges. Acrylic rods were used as tooth analogues a...

in this investigation the thickness of enamel in the gingival, middle, and incisal thirds of the labial surface of the anterior teeth were measured regarding preparation of the teeth for porcelain laminate veneers.part one, 20 extracted intact human maxillary central and lateral incisors ten of each were selected. the teeth were imbedded in autopolimerize acrylic resin. cross section was prefor...

INTRODUCTION A dental impression is a negative imprint of an oral structure that can be used to produce a positive cast of a patient's teeth as a permanent record. The accuracy of the impression affects the accuracy of the cast, and a precise impression is needed in order to create prosthesis with optimal fitting. Minimization of misfit is an important aim in prosthesis science and dental impla...

The purpose of the present study was to evaluate how ultraviolet light (UV) irradiation using an ordinary UV sterilizer would affect the bonding of experimental composite resins to an autopolymerizing acrylic resin. To this end, three composite resins and one unfilled resin--of which the compositions were similar to commercial composite resin artificial teeth--were prepared as repair composites...

Acrylic resin denture base material has been available to the dental profession for over 60 years, and although materials with superior properties have on market some time, it still remains most popular choice of clinicians. The requirement simple processing equipment low cost fabrication process are reasons its continued popularity. However, debonding acrylic teeth from resins a problem both p...

Purpose: This study was conducted to evaluate the effect of different staining solutions on color stability and surface roughness (SR) Nano hybrid composite acrylic denture teeth. Materials Methods: Fifty specimens divided into two main groups. Each group 5 subgroups each teeth were used in this test. Teeth immersed four coloring addition distilled water. Color measurements erformed using spect...

Ectodermal dysplasia is a hereditary disorder associated with abnormal development of embryonic ectodermally-derived organs including teeth, nails, hair and sweat glands. Hypodontia of the primary and permanent dentition is the most com-mon oral finding. Therefore, affected patients need dental prosthetic treatments during their developmental years. This re-port presents two cases of children a...
