Implant success often relies on the interface between bone and implant, and there are many possible causes of bone loss. A recent study has investigated the effect bone vascularisation and cortical bone levels have on marginal bone loss around implants.
Researchers at KU Leuven in Belgium evaluated 1,701 implants for the study. Radiographs were taken at placement, abutment connection and at one year following loading. The vascularisation of the bone was judged subjectively by the surgeon as either good, medium or poor. CBCTs were analysed to determine bone quality and additional data, such as ISQ values and position of implant, were also taken.
The researchers found that there was more bone loss during the early stages of healing for those with poor vascularisation. After abutment connection there was no difference between the groups. Bone loss after one year was significantly less in cancellous bone.
This study supported earlier observations that cancellous bone is better suited to rapid healing compared with cortical bone. The study, though limited in its scope, suggests that the amount of vascularisation and proportion of cortical bone should be considered when planning an implant.
This study was presented as an e-poster at the 2017 EAO Congress.
