OBJECTIVE To analyze the stress-strain states of bone and abutment teeth during the use of different prosthetic designs of fixed partial dentures with the use of relevant mathematical modeling principles. MATERIALS AND METHODS The use of Comsol Multiphysics 3.5 (Comsol AB, Sweden) software during the mathematical modeling of stress-strain states provided numerical data for analytical interpre...

AIM This study was aimed at evaluating the quality of written prescriptions for fixed and removable prosthesis in Tabriz, northwest Iran. METHODS To assess the quality of written prescriptions for fixed and removable partial dentures, a total of 600 questionnaires were distributed among 15 licensed dental laboratories receiving both fixed and removable prosthesis projects. The technicians wer...

The accuracy of 12 impression materials of six different types were studied by using complete-arch FPD impressions. Sixty impressions were made of a Columbia dentoform maxillary model with complete cast crown abutment preparations on the canines and the second molars. A one-piece casting was constructed by connecting the four individual castings made for the four abutment teeth. The master pros...

OBJECTIVES Computer-aided design (CAD) and manufacturing (CAM) allows the milling of high strength zirconia fixed partial dentures (FPD), however bonding to an inert ZrO(2) ceramic surface may effect the marginal integrity of the FPDs. The aim of this investigation was to evaluate the marginal adaptation of zirconia FPDs at the interfaces between zirconia, cement, and tooth. METHODS 32 3-unit...

Resin-bonded fixed partial dentures have been in use for over 30 years, since the concept was first introduced in the 1970s. Initial efforts in this field suffered frequent early debond, but advances in metal alloys, treatment of the fitting surface and bonding techniques have made the resin-bonded fixed partial denture a predicable treatment modality. Design principles have also evolved. Origi...

A meta-analytic technique was used to estimate the survival of implants supporting bridges or single crowns in partially edentulous patients. A survey of the literature revealed 66 studies, published between 1986 and 1996. Nine studies on single implants and 10 studies on fixed partial dentures met the inclusion criteria for the meta-analysis. Data from a total of 2686 implants, 570 single crow...

OBJECTIVES Tooth-coloured customised implant abutments and full ceramic supraconstructions thereon can be made of zirconia by computer-aided manufacturing (CAM). The aim of this study was to examine the potential limits of zirconia three-unit fixed partial dentures made on customised zirconia implant abutments in implant-tooth supported cases. MATERIAL AND METHODS Rigidly mounted implants (Xi...

Aims: To assess the treatment need among Saudi female patients attending for dental treatment at the College of Dentistry, King Saud University, Riyadh. Methods: The sample included all female patients referred to the Comprehensive Dental Course for treatment by 5th year students at the College of Dentistry, King Saud University during the academic year 2014-2015. Patients were clinically exami...

OBJECTIVE The aim of this study is a systematic review of the literature on the strength and long-term behavior of zirconia FPDs. METHODS The literature search was performed using as the primary source the Medline database. Were also imposed a set of inclusion and exclusion criteria in order to narrow the search to differentiate the two distinct parts in which it was structured the review. In...
