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)
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 AND OBJECTIVE Patients with congenitally missing teeth may present with undeveloped alveolar bone morphology, making implant reconstruction a challenge. The aim of the present study was to evaluate the outcome of dental implants after ridge augmentation with cancellous freeze-dried block bone allografts in patients with congenitally missing(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)
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)
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)
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)
Three implant impression techniques, using 3 different splinting materials, were assessed for accuracy in a laboratory model that simulated clinical practice. For group A, an autopolymerizing acrylic resin was used to splint transfer copings. In group B, a dual-cure acrylic resin was used, and for group C, plaster, which was also the impression material,(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)
BACKGROUND A one-stage surgical technique has been adopted that allows simultaneous implant placement in as little as 1 to 2 mm of residual bone. The aim of this retrospective study was to describe results and complications in sinus augmentation of severely atrophic edentulous maxillae in patients with 1 to 3 mm residual bone height and compare them to a(More)
