Purpose: Scientific data on wear from toothbrushing of luting cements for fixed partial dentures (FPDs) are limited and inconsistent, therefore the study aimed: (1) to investigate the effect of marginal gap width on cement wear and (2) to compare the resistance to wear from toothbrushing of five luting materials in an in vitro model. Materials and Methods: one zinc phosphate cement (ZPC), glass...

INTRODUCTION Chronic regurgitation of gastric acids in patients with gastroesophageal reflux disease may cause dental erosion, which can lead in combination with attrition or bruxism to extensive loss of coronal tooth tissue. CASE PRESENTATION This clinical report describes treatment of severe tooth wear of a gastroesophageal reflux disease patient who is 54-year-old Turkish male patient. Aft...

AIM To examine the oral mucosa under the denture base and to determine the influence of local factors that contribute to denture stomatitis. METHODS In this prospective, case control study 30 patients with palatal inflammatory lesions were evaluated. A degree of palatal inflammation was scored. Swab samples were taken from tongue and palatal mucosa for microbiological examination. Denture pla...

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 The purpose of this study was to evaluate the effect of differences in the retainer design on load on abutment teeth and displacement of the denture base in mandibular unilateral extension base partial removable dental prosthesis to determine the optimum design for a mechanically appropriate retainer. METHODS Three models were used. Each incorporating a removable denture with differen...

The incorporation of computer-aided design/computer-aided manufacturing (CAD/CAM) technology into complete denture fabrication brings about several advantages to the fabrication process, providing better predictability of the desired outcomes and high accuracy of denture fit, mainly because the milling of prepolymerized acrylic resin eliminates the shrinkage of the acrylic base. Also, there is ...

PURPOSE The aim of this study was to evaluate whether there is any typical deformation pattern existing in complete denture when it was dried by using the 3D scanner and surface matching program. MATERIALS AND METHODS A total of 28 denture bases were fabricated with heat curing acrylic resin (each 14 upper and lower denture bases), and 14 denture bases (each 7 upper and lower denture bases) w...

Owing to economic conditions, removable dentures remain popular despite the discomfort and reduced chewing efficiency experienced by most denture wearers. However, there is little evidence to confirm that the level of mucosal load exceeds the pressure pain threshold. This discrepancy stimulated us to review the current state of knowledge on the biomechanics of mastication with complete removabl...

PURPOSE The aim of our study was to explore the effects of different loading positions on the movements of the abutment tooth and denture base of removable partial denture with unilaterally designed framework (RPD-U). MATERIALS AND METHODS The experiment was carried out with a simulation model of a mandible without left molars. The movements of abutment tooth and denture base of the unilatera...

The purpose of this study was to evaluate differences between the occlusal contacts of edentulous patients with mandibular implant-supported hybrid dentures opposing maxillary complete dentures and those of patients with conventional maxillary and mandibular complete dentures. Six parameters related to occlusion were measured in the 2 groups (n = 40 for each group) using pressure-sensitive film...
