Abstract
Objective
To evaluate the influence of patient and implant-related factors on the changes of marginal bone levels (MBL) at implants with a follow-up ≥5 years.
Materials and Methods
At baseline (within 6 months from prosthetic insertion) and long-term (≥5 years after implant placement) visits, interproximal (mesial and distal) MBL were radiographically evaluated. To analyze factors predicting MBL change, the site (either mesial or distal) showing the highest MBL change (hChMBL site) was identified for each implant. Multilevel regression models were built to explain MBL change as well as the probability for a bone loss ≥2 mm at long-term.
Results
942 implants in 312 patients with a mean follow-up of 8.02 ± 2.5 years were analyzed. MBL change was significantly predicted by baseline MBL, oral bisphosphonate (BP) intake, history of periodontitis, diabetes, and super-hydrophilic implant surface. Higher risk for a bone loss ≥2 mm was observed in patients with history of periodontitis (OR = 9.52, 95% CI 0.72–3.79) and taking BP (OR = 6.84, 95% CI 0.21–3.63). Mandibular implants had higher odds for bone loss ≥2 mm compared to maxillary implants (OR = 3, 95% CI 0.39–1.87).
Conclusions
The findings of the present study contribute to the identification of specific clinical scenarios at higher risk for implant-supporting bone loss that need to be strictly monitored during maintenance.
期刊介绍:
Clinical Oral Implants Research conveys scientific progress in the field of implant dentistry and its related areas to clinicians, teachers and researchers concerned with the application of this information for the benefit of patients in need of oral implants. The journal addresses itself to clinicians, general practitioners, periodontists, oral and maxillofacial surgeons and prosthodontists, as well as to teachers, academicians and scholars involved in the education of professionals and in the scientific promotion of the field of implant dentistry.
