Abstract

PURPOSE
This study is to evaluate the clinical significance of the platform switching concept by comparing the marginal bone loss around platform-matched and platform-switched implants.
MATERIALS AND METHODS
Date of implant placement, diameter, length, implant-abutment connection type and absence of splinting prosthesis were investigated on patients who performed treatment with implant placement at Wonkwang University Dental Hospital Implant Center. To measure the marginal bone loss around implants, periapical radiographs of patient were used when implant was placed and when visited the center most recently by using the program, Emago advanced v5.6.
RESULTS
As a result of observing on 150 implants of 82 patients for 6 - 63 months, platform-matched implants showed 1.16 +/- 0.54 mm, platform-switched implants showed 0.68 +/- 0.27 mm of marginal bone loss.
CONCLUSION
It was considered that there is the positive effect to reduce marginal bone loss around platform-switched implants.
