T he removable partial denture (RPD) continues to be an essential prosthetic consideration in many oral reconstructions, especially when edentulous ridges posterior to a patient’s remaining teeth are to be restored. Posterior distal extension partial denture bases present a number of design challenges. Of particular concern is the equitable distribution of forces to maintain remaining alveolar ...

Microwave energy has been used as an alternative method for disinfection and sterilization of dental prostheses. This study evaluated the influence of microwave treatment on dimensional accuracy along the posterior palatal border of maxillary acrylic resin denture bases processed by water-bath curing. Thirty maxillary acrylic bases (3-mm-thick) were made on cast models with Clássico acrylic res...

Purpose: To evaluate patient satisfaction, the retentive characteristics, and masticatory efficiency in maxillary single denture wearers with 3 different bases. Material Methods: 40 patients; 10 dentate (control group (GC)) 30 completely edentulous ridges patients (43-56 years) were selected for this study. The divided into groups randomly; each received dentures; Group I (GI) conventional heat...

PURPOSE The purpose of this preliminary in vivo study was to compare force distribution on abutments (tooth or implant) and tissues supporting overdentures with two or four abutments. MATERIALS AND METHODS A convenience sample of five subjects with tooth and/or implant-supported overdentures was enrolled. Recordings were completed on each subject using a force-measuring system mounted on a me...

BACKGROUND The impact strength of denture base resin is of great concern and many approaches have been made to strengthen acrylic resin dentures. The objective of this study was to compare the impact strength of the denture base resin with and without reinforcement and to evaluate the impact strength of denture base resin when reinforced with stainless steel mesh, glass fiber, and polyethylene ...

Polymethyl methacrylate (PMMA) is one of the most widely used materials in prosthetic dentistry. Since it was introduced to dentistry, it has been successfully used in construction of denture bases. Acrylic resins have been successful as denture bases because of their ease of processing, low cost, light weight, and colour matching ability,however, acrylic resin denture base materials are low in...

PURPOSE This study evaluated the bond strength between porcelain denture teeth (Bioblend 43D) and four different polymerized denture resins (Lucitone 199, Palapress, Acron MC, Triad) with and without a bonding agent and after four different types of surface treatment (polished, HF etched, sandblasted, air-abraded). MATERIALS AND METHODS Central incisor porcelain denture teeth were divided int...

Pressure-indicating media have more diverse applications than merely the identification of areas on the denture base that cause mucosal pressure and pain. The purpose of this article is to provide guidelines for optimal use of the media and to identify alternative uses that could be considered in daily practice.
