Abstract

ABSTRACT

 

Aim The purpose of this study is to evaluate the success of a new three-dimensional CAD/CAM processing technique in full-arch implant supported rehabilitations of edentulous patients.

Materials and methods Healthy patients with edentulous mandible and/or maxilla arch were selected for the present study. The Full-Arch Implant Supported Virtual Protocol has been applied with immediate loading fixed rehabilitation. Effectiveness of digital and surgical planning, marginal bone loss, implant and prosthetic failure were recorded at 6-and 12 months follow up.

Results Seventy-six implants were placed in 15 patients, and 15 full arch  rehabilitations were delivered. Patients found  smile design previsualization very effective (93%),  guided surgery very effective (94%), and  immediate loading and temporization very effective (92%). No implant were lost (survival rate = 100%). At the 6-months radiographic evaluation, average perimplant crestal bone loss was 0.56 ± 0.12 mm for maxillary implants (n = 64 ), 0.59 ± 0.16 for mandibular implants (n = 12 ) and 12-months average perimplant crestal bone loss was 0.67 ± 0.11 mm for maxillary implants (n = 64 ) and 0.69 ± 0.16 for mandibular implants (n = 12 ). Two unscrewing episodes and one provisional prosthesis fracture occurred. No paresthesia and no prosthetic complications in definitive prostheses were registered in the whole sample.

Conclusions Within the limitations of the present study, the Virtual Implant-Prosthetic Procedure could be a satisfactory treatment in edentulous patients.

PlumX Metrics

PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
