OBJECTIVES The objectives of this study were to determine the accuracy of Periotest to monitor primary implant stability at first-stage surgery, to identify by multivariate analysis the variables associated with early implant failure and to compare Periotest with radiographic study in the diagnosis of implant stability at second-stage surgery (during osseointegration period). MATERIAL AND MET...

PURPOSE This review describes a new interactive imaging program that allows computed tomography (CT) images to be used to virtually place dental implants and construct a precise guide splint and final prosthesis for delivery at the time of implant placement. MATERIALS AND METHODS Patients with edentulous arches were recruited to participate in a trial program to assess the feasibility of usin...

OBJECTIVES The aim of this prospective study was to evaluate clinically and radiographically the success and esthetic result of immediate implant placement at the time of extraction. MATERIAL AND METHODS Twelve patients with 14 titanium screw-shaped implants (13-16 mm length and 4.3 or 5 mm diameters) were placed in the extraction sockets. Defects after implant placement were recorded, and th...

PURPOSE To compare dental implant survival rates when placed in native bone and grafted sites. Additionally, risk factors associated with dental implant loss were identified. This study was based on the hypothesis that bone grafting has no effect on implant survival rates. MATERIALS AND METHODS A retrospective chart review was conducted for patients receiving dental implants at the University...

OBJECTIVES The objective of this study is to mathematically evaluate the influence of multiple factors on implant stability quotient values in clinical practice. PATIENTS AND METHODS Resonance frequency analysis was performed at T1 (measured immediately at the time of implant placement) and at T2 (measured before dental restoration) in 177 patients (329 implants). Using a multivariate linear ...

The position, depth and direction of implant placement are often planned based on evaluation of radiographs and study casts. Insertion planned in such a manner may not be adequate for precise and safe surgery in some cases due to inadequate working clearance in the oral cavity. In order to obtain high initial stability and ensure osseointegration at the implant-bone interface, careful and preci...
