Chewing side preference is a factor that could effect prosthodontic treatment. The purpose of this study was to determine whether chewing side was another type of hemispheric lateralization comparable with footedness, handedness, eyedness and earedness. Chewing side preference was tested in 189 subjects of whom 84 were partially edentulous, 98 had a full(More)
BACKGROUND This investigation is a clinical and histological assessment of fresh-frozen bone use in the reconstruction of maxillary alveolar ridges. The study evaluates the effectiveness of this material as a bone filler prior the placement of dental implants. PATIENTS AND METHODS Sixteen patients with atrophic maxillary ridges underwent maxillary(More)
Variations in the bulk of wash in a putty-wash impression technique can result in dimensional changes proportional to the thickness of the wash material during setting. The purpose of the study was to determine the amount of wash necessary to achieve accurate stone models while using a two-step putty-wash impression technique with polyvinyl siloxane (PVS)(More)
STATEMENT OF PROBLEM Cements that yield high retentive values are believed to allow use of shorter posts. PURPOSE This study investigated the use of reinforced composite resin cement as compensation for reduced dowel length. MATERIAL AND METHODS The retention values of stainless steel posts (parallel-sided ParaPost and tapered Dentatus in 5-, 8-, and(More)
PURPOSE To review the published data on the treatment outcomes of restoring the partially edentulous patient with implant-supported removable partial dentures (ISRPDs) and describe the concept of ISRPDs and the clinical guidelines for placing implants for ISRPDs, and evaluate case series results. MATERIALS AND METHODS For the review, a literature search(More)
PURPOSE Implant failures can be divided into early and late according to the timing of failure. The purpose of this study was to characterize and compare both types. PATIENTS AND METHODS A retrospective cohort study was conducted in 194 patients (98 men and 96 women) who presented after dental implant failures during a 6-year period (2000 to 2006). The(More)
PURPOSE To assess the clinical effectiveness of immediate nonfunctional loading for single-tooth implants placed in the anterior maxilla following augmentation with cancellous freeze-dried block graft. MATERIALS AND METHODS The clinical outcomes of immediately nonfunctionally loaded implants up to 18 months after placement in the anterior maxilla were(More)
BACKGROUND Pre-implant augmentative surgery is a prerequisite in many cases in the anterior maxilla to achieve a stable, long-term esthetic final result. PURPOSE The aim of the present study was to evaluate the outcome of ridge augmentation with cancellous freeze-dried block bone allografts in the anterior atrophic maxilla followed by placement of dental(More)
STATEMENT OF PROBLEM There is much discussion in the dental literature concerning the effect of the impression technique on the accuracy of cast restorations. PURPOSE This study assessed the accuracy of 3 putty-wash impression techniques using the same impression material (polyvinyl siloxane) in a laboratory model. MATERIAL AND METHODS The 3 putty-wash(More)
PURPOSE To prospectively evaluate the outcome of dental implants placed in the post-traumatic anterior maxilla after ridge augmentation with cancellous freeze-dried block bone allografts. MATERIALS AND METHODS Patients presenting with a history of anterior dentoalveolar trauma with bony deficiencies in the sagittal (≥3 mm) and vertical (<3 mm) planes(More)
