PURPOSE Osteoblast attachment on titanium surfaces is necessary to achieve new bone formation and osseointegration. The purpose of this study was to examine osteoblast attachment on irradiated titanium disks. MATERIALS AND METHODS Machined, hydroxyapatite (HA)-coated, sandblasted, and titanium plasma-sprayed (TPS) surfaces were irradiated with either a(More)
INTRODUCTION As a consequence of extraction, the height of the buccal wall tends to decrease and results in the disappearance of bundle bone. To modify bone remodelling after extraction, various ridge preservation techniques have been proposed. The present research was drawn up with the following considerations in mind: to evaluate and to compare changes of(More)
Advances in biomaterial technology and clinical research have equipped clinicians with efficient tools to provide advanced treatment options. As a result, some of the original prerequisites for osseointegration have been redefined to satisfy patients' expectations of reduced treatment time, improved aesthetics, and increased comfort. Novel treatment(More)
PURPOSE The purposes of this study were to evaluate the clinical success of bone reconstruction of the severely atrophic maxilla using autogenous bone harvested from the anterosuperior edge of iliac wing and to analyze the clinical success and the marginal bone level of dental implants placed 4 to 5 months after bone grafting and before prosthetic(More)
PURPOSE The aim of this study was to evaluate the rate of complications in maxillary sinus augmentation surgery and the impact of complications on subsequent implant treatment in a patient population with severe maxillary atrophy scheduled for treatment under general anesthesia. MATERIALS AND METHODS The study population consisted of 70 patients (124(More)
BACKGROUND The preservation of bone volume immediately after tooth removal might be necessary to optimize the success of implant placement in terms of esthetics and function. The objectives of this randomized clinical trial were two-fold: 1) to compare the bone dimensional changes following tooth extraction with extraction plus ridge preservation using(More)
The aim of the present clinical study was to evaluate the placement of transmucosal implants into fresh extraction sockets and their immediate restoration with temporary crowns. A series of 22 cases with a 12-month follow-up is presented. Twenty-two patients (15 women and 7 men; mean age 39 years) who needed a single tooth replaced because of vertical or(More)
OBJECTIVES The aim of the present study was to investigate in a randomized-controlled clinical trial the performance of rotary instruments compared with a piezoelectric device during maxillary sinus floor elevation. MATERIALS AND METHODS Thirteen patients who required a bilateral maxillary sinus augmentation for implant-prosthetic rehabilitation were(More)
PURPOSE To examine the distribution of bacteria into the internal and external surfaces of failed implants using histologic analysis. MATERIALS AND METHODS There were 10 failed pure titanium and 5 failed hydroxyapatite-coated titanium implants consecutively removed various years after their placement. Criteria for fixture removal were peri-implant(More)
BACKGROUND Some of the original surgical protocols for implant surgery have been reassessed to satisfy the patient's continuously increasing expectation for shorter rehabilitation time, improved esthetics, and increased comfort. The aim of this study was to evaluate the 12-month clinical success of 18 single-tooth implants inserted immediately after tooth(More)
