Synergistic effect of nicotine on different implant platform design in implant-assisted mandibular overdenture, 1- Year clinical and radiographic study

Abstract

Background In implant therapy, peri-implant bone loss has been noticed mainly in the first year after prosthesis insertion. This bone loss can sometimes jeopardize the outcome of the treatment. Different implant platform designs are widely used in implant dentistry; however, its influence on the health of the surrounding soft tissues and marginal bone level alterations in implant-assisted overdentures particularly in smoker patients, remains inconclusive. The purpose of this study will be to evaluate the effect of nicotine on different implant platform designs in complete mandibular implant-assisted overdenture patient. Materials and methods Ten male smoker patients were selected for this study. Split mouth study design will be used in this study where, Group I represented the right side of the patients’ mandibular interforamenal region restored with platform-switched implant and Group II represented the left side of the patients’ mandibular interforamenal region restored with nonplatform swithched implants. The patients received complete mandibular assisted overdenture with O-ring attachment. Clinical and Radiographic evaluations were carried out for every patient at regular recall visits at the time of insertion, 6, and 12 months. At the end of the study, all implants of both groups were successfully osseointegrated. The data of this study were collected, tabulated, and statistically analyzed by IBM-SPSS statistics software (Independent T-test Samples). Result There were insignificant differences between both groups regarding plaque index (PI), bleeding index (BI), pocket depth (PD) and stability of the implants. Radiographically, there were significant differences in the mandibular bone density at the bone implant interface and marginal bone loss between both groups. Group I implant represented less marginal bone loss and higher bone density than Group II implants. Conclusion In smoker patient Platform-Switched dental implant is the implant of choice to control marginal bone loss around implants.
