ABSTRACT

The growing interest in digital technologies has affected, in recent years, many areas of various fields of work, and dentistry is one of them; in fact, implantology and modern prosthetics are increasingly turning to digital technology. Both the traditional and digital impressions are operator dependent, so it is necessary that each prosthodontist, or rather any dentist, knows how to best capture the anatomical/mechanical details, in the case of implants, of each patient treated. Failure to do so would mean sending into production an artifact that already has underlying defects inherent in the impression taken poorly by the dentist or cast incorrectly by the dental technician. The purpose of this study is to compare analog and digital work-flow, in the design of the surgical and prosthetic procedures using CSR implants (CSR Implant System, Sweden&Martina, Due Carrare, Padua, Italy) associated with conometric technique. The innovative part of the CSR implants (CSR Implant System, Sweden&Martina, Due Carrare, Padua, Italy) lies in the DAT connection: a double internal conical contact interface between the abutment and the implant and between the screw and the abutment. In fact, the tapered technique that we find in the DAT connection just mentioned allows to obtain an implant-supported fixed prosthesis without the use of cement or screws fixation between abutment and prosthesis which, at the same time, is easily removable by the clinician, while still being a fixed prosthesis. The aim of this study is to evaluate the stability of implant prostheses rehabilitation, comparing the traditional technique (control group) with the digital technique (test group).
