Background
The first year of prosthetic loading is crucial to peri‐implant bone levels; however, contributing factors are yet barely understood.
Purpose
The purpose of the study is to investigate the influence of patient‐, implant‐, and prosthetic‐related parameters on marginal bone resorption in partially edentulous patients within the first year of prosthetic loading.
Materials and Methods
This retrospective multifactorial analysis involved the following influencing factors: patient gender and age, implant diameter, implant location and neck design, insertion torque, insertion depth, splinted versus single‐tooth restorations, crown height space, and crown‐to‐implant ratio.
Results
Mean peri‐implant bone resorption around 200 dental implants was 0.98 ± 0.76 mm and significantly correlated to higher implant insertion depth (p < .001), whereas no association to prosthetic parameters could be observed.
Conclusions
Within the limits of the present analysis, it can be concluded that apical implant positioning may constitute a relevant determinant of early peri‐implant bone resorption.
