Assessment of the effect of clinical risk factors on marginal bone loss in 2 implant-supported locator retained mandibular overdentures

The objective of this study is to evaluate the effect of clinical parameters of gender, age, implant length, implant diameter, interimplant distance and locator height on marginal bone loss in 2 implant-supported locator retained mandibular overdenture prosthesis in 6., 12. and 24. recall sessions after loading. Clinical and radiographic data of patients who were treated between 01/01/2014 and 01/04/2018 were retrieved from the archieves. The clinical data of gender, age, implant length, implant diameter and locator height was recorded. The mesial and distal marginal bone levels of all implants and interimplant distances were determined at baseline and 6., 12, and 24. month recall sessions on panoramic radiographs in a computer program. Statistical analysis was used to evaluate the effect of implant length, implant diameter, gender, age, interimplant distance and locator height on marginal bone loss in 6., 12. and 24. month control evaluations. A total of 57 patients with a mean age of 59,2±9.8 and 114 implants were included in the study. Among the aferomentioned parameters, only the locator height had major effect on the distal and mesial marginal bone loss.(p
