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)
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 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)
The aim of this study was to investigate the reliability between different examiners when using the axis I of the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). The hypothesis was that the standardized RDC/TMD examination protocol enables calibrated examiners to evaluate all examination items reliably. After calibration training by(More)
PURPOSE The aim of this study was to investigate the ability of clinical and magnetic resonance imaging (MRI) diagnoses to predict pain in the temporomandibular joint (TMJ). MATERIALS AND METHODS One hundred forty-nine patients were examined by 2 calibrated examiners in strict accordance with the Research Diagnostic Criteria for Temporomandibular(More)
OBJECTIVES The purpose of this study was to evaluate both reliability and validity of the assessment of the shape of the mandibular condyle in panoramic images of the TMJ. STUDY DESIGN Forty subjects were included and were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders. Panoramic radiographs (PRs) and magnetic(More)
INTRODUCTION This hypothesis-generating study was performed to determine which items in the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and additional diagnostic tests have the best predictive accuracy for joint-related diagnoses. METHODS One hundred forty-nine TMD patients and 43 symptom-free subjects were examined in clinical(More)
The purpose of this prospective cohort study was to assess the performance of tooth-supported, long-span, zirconia fixed dental prostheses (FDPs). Thirty FDPs with span lengths from 36 to 46 mm (mean 40·33 mm), with 4-7 units and with connector dimensions ∼9 mm(2) were inserted (19 in the posterior region, 11 including anterior teeth) using glass-ionomer(More)
The aim of this in vitro study was to evaluate the fracture resistance of upper and lower incisors restored with glass fiber reinforced posts (FRP). There were 32 upper and 32 lower incisors endodontically treated and FRPs were cemented, using pretreated (Rocatec) and non-pretreated posts. Crowns were fabricated and cemented with Ketac-cem or Panavia.(More)
The purpose of this study was to evaluate the fracture-load values of cantilevered all-ceramic fixed partial dentures (FPDs). Fifty FPDs were manufactured using a zirconia frame to replace a missing molar. The FPDs were divided into five groups, each with a different framework design. After thermocycling and mechanical loading, the load to fracture was(More)
