OBJECTIVE This study evaluated the effect of chemical polishing on the internal adaptation of complete denture bases fabricated with Veracril® resin and polymerized by either the conventional (C) or microwave (M) techniques. MATERIAL AND METHODS Six groups (n=6/group) were tested: 1) C + no polishing (CO); 2) C + chemical polishing (CQ); 3) C + immersion in hot water at 75ºC (CW); 4) M + no p...

Objectives; This study was carried out to compare the posterior palatal base distortion of denture bases processed with ProBase Hot to those processed by conventional heat cure acrylic resin (Acrostone) before and after water immersion. Study design; Twenty waxed denture bases were prepared for U-shaped palatine arch form, ten for each denture base material. Waxed denture bases were flasked, pa...

The objectives of this study were to compare the arrangement of teeth according to the bone support concept with the neutral zone concept, Evaluate the influence of two arrangement schemes on denture success. A total of 128 patients were equally allocated into two groups, according to period of edentulism. All groups were provided neutral zone and conventional dentures. Post insertion assessmen...

Maxillary labial and buccal frena are considered as normal anatomic structures in the oral cavity. However, they may exist intraorally as a thick broad fibrous attachment and/or become located near the crest of the residual ridge, thus interfering with proper denture border extension resulting in inferior denture stability, retention and overall patient satisfaction. This case report highlights...

Objective. To investigate the influence of reproduction of different thickness and palatal rugae materials on complete dentures speech using Computerized Speech Lab (CSL) (spectrogram). Materials and Methods. Three completely edentulous male patients (aged 50-60 years) were selected for reading a paragraph. Twelve upper dentures were constructed, four for each patient. The patients' speech grou...

statement of the problem: candida species are believed to play an important role in initiation and progression of denture stomatitis. the type of the denture material also influences the adhesion of candida and development of stomatitis. purpose: the aim of this study was comparing the adherence of candida albicans to the conventional and injection molding acrylic denture base materials. materi...

The aim of this in vitro study was to compare the color stability of commercially available porcelain, reinforced acrylic, and conventional acrylic denture teeth materials used in removable prostheses. Two brands of porcelain (Unilux-Enta Lactona-Holland and Vivoperl-Ivoclar-Liechtenstein), 2 brands of reinforced acrylic (Optodent-Bayer-Germany and Ivolek-Ivoclar-Liechtenstein), and 2 brands of...

A dental implant is a surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown,bridge,denture,facial prosthesis or even can act as an orthodontic anchor.A variable amount of healing time is required for osseointegration before either the dental prosthetic (a tooth, bridge or denture) is attached to the implant or an abutment is placed w...
