The long-term success of an implant depends on the stability of bone support for the implant. Most crestal bone loss occurs in the first year of implant placement. Platform-switching is an approach which can be clinically applied to preserve the crestal bone. The concept of ‘platform switching’ refers to the use of a smaller-diameter abutment on a larger-diameter implant collar. The purpose of the present study was to evaluate crestal bone level around platform-switched implants.
Materials and methods
Twenty implants with 5 mm diameter were placed in mandibular molar region. All implants had been placed at the crestal level at the time of surgery. Radiographs with grid were obtained 3, 6 and 12 months after loading and were evaluated by screen caliper software measuring the location of the crestal bone level relative to the implant platform.
Results
The implants showed a mean bone loss of 0.76 ± 0.1265 mm on mesial side and 0.72 ± 0.1481 mm on distal side after 1 year.
Conclusion
The findings of the current trial indicated that the use platform-switched implants lead to better preservation of crestal bone.
