Purpose: The aim of this retrospective study was to compare marginal bone loss and survival rates of double short implants(multiple implant) which had been installed and restored in severely atrophic maxillary molar site without a grafting procedure.
Material and Method: The subjects were patients (90 patients, 180 implants) who had been installed double short implants in severely atrophic maxillary single molar site without bone augmentation procedure from 2006 to 2014 in dental clinic in Chuncheon city. Following data were collected from dental records and radiographic panoramic views: patient’s age, gender, smoking status, implant site, timing of implant installation, residual ridge height. The correlation between those factors and survival rate and marginal bone loss were analyzed. Statistical analysis was performed using Chi-square test, Student’s t- test and ANOVA.
Result: Eleven implants in 6 patients failed and the cumulative survival rate was 93.9%. No significant differences were found in relation to the following factors: patient’s age, gender, implant site, timing of implant installation (P> .05). There were significant differences in smoking status and residual ridge height(P< .05). The average follow-up time was 45 ± 14.7 months. The mean marginal bone loss of survived 169 implants was 0.08 ± 0.59 mm.
Conclusion: Despite the short term outcomes, the survival rate of double short implants was comparable to normal length implants. This study demonstrated that placement of double short implants without the use of bone grafting procedure for severely atrophic posterior maxilla is a simple and predictable treatment procedure.
