OBJECTIVES The purpose of this prospective long-term study was to evaluate the incidence of the most common technical problems, namely screw loosening, screw fracture, fracturing of veneering porcelain and framework fracture in implant-supported fixed partial dentures (FPDs), and assess the survival and success rate (event-free survival) after 5 years of(More)
UNLABELLED Implant overdentures and conventional prostheses have been compared in several trials using a variety of functional and oral health-related quality of life (OHQOL) outcomes. In this paper, we describe the impact of implant overdentures on general and OHQOL in seniors. OBJECTIVES To compare the oral health-related and general quality of life of(More)
Dental implants provide patients with restorative options for the edentulous maxilla. Both fixed and removable prostheses can be attached to the edentulous maxilla, but the efficacy of different designs has not been determined. In this two-session within-subject crossover trial we compared maxillary implant retained fixed prostheses with removable implant(More)
OBJECTIVES This study compared the fracture strength and survival rate of endodontically treated crowned maxillary incisors with approximal class III cavities and different core build-ups. METHODS Sixty-four caries free human maxillary central incisors were selected for standardized size and quality, endodontically treated and prepared with approximal(More)
STATEMENT OF PROBLEM Prefabricated metal and ceramic posts can be used with direct or indirect cores as an alternative to the conventional cast post and core. It is unclear how the fracture strength of zirconia posts with composite or ceramic cores and titanium posts with composite cores compares to the fracture strength of gold posts and cores after(More)
The study was designed to provide clinical outcome data for two treatments of the shortened dental arch (SDA). In a multicenter randomized controlled clinical trial, patients with complete molar loss in one jaw were provided with either a partial removable dental prosthesis (PRDP) retained with precision attachments or treated according to the SDA concept(More)
OBJECTIVES To measure expectations of satisfaction with implant and conventional denture treatment in 2 groups of edentulous people and compare them with their resultant ratings of satisfaction to determine if either treatment meets the pretreatment expectation. METHOD AND MATERIALS One hundred sixty-two edentulous middle-aged (MA, n = 102) and senior (S,(More)
PURPOSE To review the influence of prosthodontic and dental implant treatment on patient satisfaction and oral health-related quality of life (OHQOL) based on a systematic search of the literature. MATERIALS AND METHODS A systematic literature search was carried out for articles published between 1960 and February 2003. Details of the search process and(More)
The aim of this study was to compare titanium-reinforced ZrO(2) and pure Al(2)O(3) abutments regarding their outcome after chewing simulation and static loading. Forty-eight standard diameter implants with an external hexagon were divided into three groups of 16 implants each and restored with three different types of abutments (group A: ZrO(2) abutments(More)
