Clinical Outcome of Dentsply Sirona EV Implants: A Retrospective Study of 500 Implants With 6-year Follow-up
Clinical Outcome of Dentsply Sirona EV Implants: A Retrospective Study of 500 Implants With 6-year Follow-up
Retrospective observational study of 500 implants placed between 2014 and 2020 of the same dental implant system (AstraTech Implant System EV, Dentsply Implants, Mölndal, Sweden).
The purpose of this study is to assess the cumulative survival, success and complications rates obtained with the use of AstraTech Implant System EV in one clinical center from market launch to 2020
All clinical records of patients with this implant system will be collected and the following data will be recorded:
Patient gender Date of placement Dimensions and location of implant(s) placed Type of implantation Design of the implant-supported dental prosthesis, single or partial, screw-retained or cemented Date of last radiographic control Type of biological and/or mechanical complications that occurred In biological complications, presence or absence of inflammatory signs and presence or absence of peri-implant bone loss.
For mechanical complications, screw loosening, porcelain fracture, fracture of the prosthetic abutment or fracture of the implant.
Date of explantation if present
The mean, standard deviation (SD), and percentage will be calculated for all recorded parameters.
A life table will be made with cumulative survival and success rate (CSR), according to Kaplan-Meier analysis. Correlations and regression analysis will be performed to assess the influence of the variables on the outcomes
Conclusions will be drawn based on the results obtained.
Inclusion Criteria:
All patients who receive Astra Tech EV dental implant system placement.
Exclusion Criteria:
None
