STATEMENT OF PROBLEM Most processed resin denture bases do not fit the cast accurately because of polymerization changes in the resin. The fit is more noticeable in the palate between the denture base and the cast. Therefore, development of a polymerization system that will improve the fit of a denture base to the cast is lack of worth considering to improve the fit and retention of the denture...

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...

PURPOSE To study the frequency of and factors associated with the decision to perform single implant treatment after tooth extraction by general practitioners in a private, fee-for-service setting. MATERIAL AND METHODS One hundred practitioners with a general dental practice in Ghent were randomly selected. Clinicians were asked to fill in a study form for every single extraction they perform...

objective: studies have demonstrates that physical properties of denture base affect patient satisfaction and acceptance. thermal conductivity is among the most important properties of denture base influencing the sense of taste and gingival health. the conventionally used acrylic resin has a low coefficient of thermal conductivity. this study aimed to improve the thermal conductivity of acryli...

The prosthetic rehabilitation of patients with an edentulous maxilla opposing mandibular anterior natural teeth is one of the most challenging situations that a clinician encounters. Occlusal forces from the opposing natural teeth may cause fractures in the maxillary prosthesis and also result in residual ridge resorption of the edentulous maxilla. Prosthodontists try overcoming this Combinatio...

Background The purpose of this study was to compare the displacement tooth arrangement in dentures fabricated by additive manufacturing (AM) and heat curing. Methods Three-dimensional (3D) scanning performed for edentulous jaw models. After teeth were arranged, 3D wax denture performed. Heat-cured with heat-cure polymer resin. Based on data obtained subtracting model from data, AM ultraviolet-c...

PURPOSE The present material reports on prosthodontic complications in a trial of 51 patients with prostheses supported by single-stage implants over a period of 36 months. MATERIALS AND METHODS One hundred eighty-six single-stage implants were placed in 51 patients over a 3-year period in 2 carefully controlled prospective clinical trials. Nineteen of the patients (103 implants) were complet...

The aim of the study was to examine changes in the position of the abutment teeth (AT), size of undercuts for a denture clasp, as well as an existence of an adequate preparation of abutment teeth. A total of 156 casts of partially edentulous jaws, with 460 AT, were analyzed. The size of undercuts, a degree of abutment rotation, inclination and migration were measured using a dental parallelomet...

Fluorinated denture base acrylic resins can present more stable physical properties when compared with conventional polymers. This study evaluated the incorporation of a fluoroalkyl methacrylate (FMA) mixture in a denture base material and its effect on roughness and flexural strength. A swelling behavior assessment of acrylic resin specimens (n=3, per substance) after 12 h of FMA or methyl met...
