Investigational Clinical Trial of a Prototype Optoelectronic Computer-Aided Navigation Device for Dental Implant Surgery.

Purpose: New digital technologies enable real-time computer-aided (CA) three-dimensional (3D) guidance during dental implant surgery. The aim of this investigational clinical trial was to demonstrate the safety and effectiveness of a prototype optoelectronic CA-navigation device in comparison with the conventional approach for planning and effecting dental implant surgery.

Materials And Methods: Study participants with up to four missing teeth were recruited from the pool of patients referred to the University of Toronto Graduate Prosthodontics clinic.

Benchmarking Outcomes in Implant Prosthodontics: Partial Fixed Dental Prostheses and Crowns Supported by Implants with a Turned Surface over 10 to 28 Years at the University of Toronto.

Purpose: The aim of this noninterventional, retrospective study was to benchmark the outcomes of patients with partial fixed prostheses supported by implants treated at the University of Toronto at least 10 years earlier. A study protocol for assessing outcomes on like patients developed at the University of Bern, Switzerland, was followed.

Materials And Methods: All patients who had received at least one implant before 2002 were considered eligible to be included in the study (n = 298).
