Effect of varying horizontal mismatched implants on crestal bone level and peri-implant soft tissue: An in vivo study

AUTHOR(S): Dr. Renu Gupta, Dr. RP Luthra and Dr. Rajender Singh
ABSTRACT:Purpose: To evaluated the effect of varying horizontal mismatched implant-abutment interface on hard and soft tissue following one-stage dental implant placement in mandibular posterior region.
Materials and Methodology: A Prospective clinical study was conducted across 20 subjects (8 males and 12 females) based on the inclusion and exclusion criteria. Subjects were broadly divided into two groups with 10 dental implants in each i.e. implant with 0.3-0.6 mm implant-abutment interface horizontal mismatch and implant with 1-2 mm implant-abutment interface horizontal mismatch. Single stage protocol was performed. The subjects were evaluated radiographically at baseline (at time of implant placement) and 2 month, 4 month and 6 month post-operatively for crestal bone changes and soft tissue evaluation.
Result: The present study showed that on both proximal sides, the mean change from 0 month, 2 months, 4 months and 6 months for 1-2mm mismatch at bone implant contact was significantly lower than with 0.3-0.6mm mismatch (+0,07 against +0.26 mm on mesial side and +0.15 against +0.33mm on distal side at 6 months). This indicates that the loss of bone during the six-month period was significantly lower with 1-2mm mismatch compared to with 0.3-0.6mm implant-abutment interface mismatch. Therefore, the results of the present study confirms the hypothesis that increased mismatch at bone implant contact result in lesser crestal bone reduction.
Study also shows the comparison of probing depth (PD) and bleeding on probing (BOP) at different time interval between group with implant-abutment interface mismatch of 0.3-0.6 mm and group with implant-abutment interface mismatch of 1-2 mm. There was no statistically significant difference in PD and BOP of both the groups at baseline and 2nd, 4th and 6th month.
Conclusion: It was concluded from present study that use of 1-2mm implant abutment horizontal mismatch interface, preserve more periimplant crestal bone and produces more favourable soft tissue response than 0.3-0.6mm implant abutment horizontal mismatch interface.
