Aim: The aim of this study was to clarify the occurrence regions and sites of peri-implant bone resorption and inflammation in partially-edentulous patients.
Methods: Five hundred one partially-edentulous patients with 738 implants in function for more than 5 years were included in this study for the evaluation of the bone resorption by using dental radiograph and probing. Considering physiological bone remodeling, the mean mesio-distal bone resorption around the implant was measured on dental radiograph.
Results: In 65 patients (13.0% of the total patients) with 76 implants (10.3% of the total implants), peri-implant bone resorption was identified. The mean functional loading time of these implants was 8.4 years. Occurrence regions were frequently found in the molar regions in maxilla (15.4%) and the molar region in mandible (10.0%) In these leisions detected radiologically, the bleeding on probing was seen in 95.2% of the buccal sites in mandibular molar regions, 70.0% of the palatal sites in maxillary molar regions and 56.7% of the buccal sites in maxillary molar regions with statistically significant differences.
Conclusion: From the limitation of the information in this study, it was concluded that the sites that tend to be vulnerable to peri-implant inflammation were the buccal site in mandible, and the buccal and palatal sites in maxilla.
