Retrospective study on marginal bone loss around maxillary anterior implants with or without bone graft / 대한치과보철학회지

ABSTRACT

PURPOSE: This study is to evaluate the clinical significance of implantation with simultaneous bone graft by comparing the marginal bone loss around maxillary anterior implants with or without bone graft MATERIALS AND METHODS: Patients treated with implant-retained restorations on maxillary anterior region at Implant Center, Dental Hospital, Wonkwang University between June 2011 and May 2014 were included in this study. Date of implant placement, implant diameter, implant length, implant-abutment connection type and whether the bone graft was done were investigated. The patient's periapical radiographs taken immediately after implantation and at the most recent visit were compared. Marginal bone loss was measured using Emago advanced v5.6 program (Oral diagnostic systems, Amsterdam, Netherlands). Statistical analysis was done in independent t-test by using SPSS 22.0 program. RESULTS: As a result of observing on 83 implants (without bone graft 44, with bone graft 39) of 52 patients for 6 - 45 months (average 18.4 months), implants without bone graft showed 1.42 ± 0.42 mm, implants with bone graft showed 1.28 ± 0.45 mm of marginal bone loss. CONCLUSION: In limitations of this study, implants with simultaneous bone graft had significantly less marginal bone loss than implants without bone graft.
