Clinical Trial Summary

The Aim of this study randomized prospective clinical trial is to examine and compare periimplant tissue changes between heavy smokers and non-smokers at 12 months post loading using the alpha Bio Neo standard diameter implants with conical abutment.

Description:

Peri-implant marginal bone level is one of the most important references criteria to monitor peri-implant health.A radiographically measured marginal bone loss of up to 1.5 mm during the first year of loading, followed by a marginal bone loss of up to 0.2 mm for each succeeding year, is an acceptable criterion to determine implant success. Smoking has been implicated in many adverse systemic outcomes, including tooth loss, alveolar bone loss and dental implant failure. Platform switching, also known as platform shifting, is whenever an abutment is used that is smaller in diameter than the implant platform. Platform switching can help prevent crestal bone loss. The hypothesis of the present study is that the use of conical abutment might reduce marginal bone loss around dental implants in both smokers and non-smokers alike.
