Official title
Clinical, Radiographic, and Histomorphometric Analysis of AstraTech Implant EV Placed and Immediately Provisionalized Into Preserved Alveolar Ridges: A Prospective 3-Year Outcomes Study
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The revised purpose of this study is to compare and evaluate the stability of the implant body, survival rate, bone-level changes, and the implant's soft-tissue outcomes over a period of 1 year. Only 1 tooth is studied per participant. In July of 2024, the revised protocol and revised Statistical Analysis plan were amended post-hoc, and the revised protocol and statistical analysis plan were approved by the IRB review committee in July of 2024. As a result, the study has been terminated due to a change in the study's data analysis, and so the study will only analyze data up to and including the 1-year point.
