OBJECTIVE To obtain information about the subjective oral health status of non-clinical elderly populations of urban regions of Germany, one in the East and one in the West, by using OHIP-14 and, for first time, the GOHAI, and, furthermore, to compare the results obtained by use of both instruments. BASIC RESEARCH DESIGN Cross-sectional. CLINICAL(More)
OBJECTIVES The objective of this study was to evaluate the clinical performance of zirconia-based all-ceramic fixed partial dentures anchored by inlays. METHODS A total of thirty FPDs, manufactured using a zirconia frame and veneered with press ceramic, were anchored by use of inlay retainers. All FPDs were designed to replace one missing molar and were(More)
OBJECTIVES Translation, reliability analysis and validation of a German version of the Geriatric/General Oral Health Assessment Index (GOHAI) was the aim of this study. METHODS Translation was performed by a forward-backward process. Validity was assessed as convergent validity in comparison with another self-perceived assessment of oral health (OHIP-14)(More)
OBJECTIVE The purpose of this study was to evaluate temporomandibular joint morphology and to compare possible structural variations in the temporomandibular joint anatomy of symptomatic anterior disk displacement patients with possible structural variations in the temporomandibular joint anatomy of symptom-free volunteers. STUDY DESIGN Fifty-six(More)
AIMS To investigate the course of myofascial pain defined by Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) over a period of 5 years, and to identify prognostic factors from baseline data. METHODS Subjects were 155 consecutive patients and 80 community cases identified from an age-stratified representative population sample; all(More)
PURPOSE The objective of this retrospective study was to compare the incidence of chipping of implant-supported, all-ceramic, and metal-ceramic single crowns. MATERIAL AND METHODS One hundred fifty-three patients (51.7% male, mean age 55.0 years) received 232 cemented implant-supported single crowns. One hundred and seventy-nine crowns had a metal(More)
PURPOSE The aim of this prospective randomized controlled trial was to evaluate the influence of clinical baseline characteristics on the survival of 2 post systems. MATERIALS AND METHODS One hundred patients needing a post were included. Half the patients received a glass fiber-reinforced post (FRP), and the other half received metal screw posts (MSP).(More)
The purpose of this study was to evaluate enamel wear caused by monolithic zirconia crowns and to compare this with enamel wear caused by contralateral natural antagonists. Twenty monolithic zirconia crowns were placed in 20 patients requiring full molar crowns. For measurement of wear, impressions of both jaws were made at baseline after crown cementation(More)
The purpose of this prospective cohort study was to assess the performance of tooth-supported, extended zirconia, fixed dental prostheses (FDPs). Thirty FDPs with span-lengths between 36 and 46 mm (mean: 40.33 mm), four to seven units and with connector dimensions of approximately 9 mm(2) were inserted (19 in the posterior region, 11 including anterior(More)
OBJECTIVE To assess the survival rate of two different post systems after 5 years of service with a prospective randomized controlled trial. METHOD AND MATERIALS One hundred patients in need of a post were studied. Half of the patients received long glass fiber-reinforced posts, while the other half received long metal screw posts. The posts were assigned(More)
