Dental implant, Implant stability, Resonance frequency analysis, Bone loss


Background : The patients who had lost their natural teeth and have been wearing the full denture for a long time, will have an ill-fitting lower denture. Two implants for retaining a full lower denture can solve the problem.

Objective : The project was to examine the implant’s stability, using the resonance frequency analysis (RFA) method. The marginal bone loss was measured from a panoramic radiograph.

Method : Thirty patients, age over 60, have been chosen from the implant project celebrating King’s 80th Birthday Anniversary on 5 December 2007. All of them were treated at Institute of Dentistry, Department of Medical Services. The study was followed the implant stability and the marginal bone loss around the implants.

Result : The study showed the follow-up 20 ± 8.49 months in average. The implant stability quotient (ISQ) value was 71.24 ± 2.95 and the mean marginal bone loss was 1.52 ± 0.59 millimeters.

Conclusion : Khao Aroi implant system had high stability and the level of bone loss meets the standard success criteria.
