OBJECTIVE This study compared the effects of three different methods of preparing bone implant sockets (drilling, osteotomes, and piezoelectric device) on osseointegration using resonance frequency analysis (RFA). STUDY DESIGN An experimental prospective study was designed. MATERIAL AND METHODS Ten adult beagle dogs were studied. After 5 weeks, 23 out of 28 initially placed implants in the ...

Background. The aim of the present study was to have normative data of nasal bone thickness for use before reconstructive surgery and nasal augmentation through radiography analysis. Methods and Materials. In this descriptive-analytical study, 74 patients were selected from people referred to Radiology Department of Isfahan University for CBCT examination in 2012. Patients with a history of nas...

STUDY DESIGN A retrospective study. PURPOSE To determine the feasibility and effectiveness of revisional percutaneous full endoscopic discectomy for recurrent herniation after conventional open disc surgery. OVERVIEW OF THE LITERATURE: Repeated open discectomy with or without fusion has been the most common procedure for recurrent lumbar disc herniation. Percutaneous endoscopic lumbar discect...

Objectives The objective of the present study is to present the current best evidence for enhancement of the vertical alveolar bone height and oral rehabilitation of the atrophic posterior maxilla with dental implants and propose some evidence-based treatment guidelines. Material and Methods A comprehensive review of the English literature including MEDLINE (PubMed), Embase and Cochrane Libra...

BACKGROUND The use of osteotome for vertical bone augmentation and localized sinus elevation with minimal surgical trauma represents a suitable procedure to increase the vertical dimension of available bone for implant placement. PURPOSE The aim of this study was to report clinical and radiographic results of localized management of sinus floor (LMSF) in fresh molar sockets at 13-year follow-...

BACKGROUND Migration of dental implants into the maxillary sinus is an uncommon, but increasingly reported complication. Implant migration may result from initial lack of primary stability, intrasinusal and nasal pressure changes, autoimmune reaction to the implant or incorrect distribution of occlusal forces. This retrospective study aims at analyzing the factors that may influence implant mig...

Introduction The investigation of the trabecular bone strength in acetabular area and its dependence on age gender may provide a theoretical basis for development implants replacement. purpose this study was to determine mechanical characteristics tissue supra-acetabular region patients different groups. Materials methods cadaveric material 60 studied included 20 young (age range, 18 44), middl...

Objective: Although endoscopic drill has the advantages in manipulation and hemostasis, whose low efficiency blurred vision reduce efficacy of lumbar unilateral laminotomy with bilateral decompression (LE-ULBD). The present study was designed to evaluate safety full-visualized trephine/osteotome LE-ULBD surgery for severe stenosis.Methods: Fifty-seven stenosis patients who underwent between Jan...

PURPOSE Implant survival rates using a bone-added osteotome sinus floor elevation (BAOSFE) procedure with simultaneous placement of a non-submerged sand blasted with large grit and acid etched (SLA) implant are well documented at sites where native bone height is less than 5 mm. This study evaluated the clinical results of non-submerged SLA Straumann implants placed at the time of the BAOSFE pr...
