Abstract:

Objectives: The objectives of this research were to analyze the relationships between peri-implant conditions and periodontal conditions in Chinese patients with dental implants in place for at least 1 year. Methods: Seventy-six patients (mean age, 41±10 years; range, 21-69 years) who received placement of 120 dental implants (Straumann®), (mean 1.6 implants per subject; range, 1-5 implants per subject) after a mean period of 25 months (range, 12-66 months) responded to recall. Clinical examinations were performed around the implants and natural teeth. Peri-apical radiographs were taken by the long cone technique for implants and radiographic bone level (BL) was measured. Comparisons of the peri-implant conditions were performed between the patients with different periodontal conditions by t-test and chi-square test. The relative risk of periodontal condition as a risk factor for peri-implant conditions was analyzed by logistic regression. Results: Subjects who presented with �5% sites with probing depth (PD) �4 mm and �30% sites with bleeding on probing (BoP) in the dentition showed significantly poorer peri-implant conditions (58% vs. 18% subjects who had maximum modified gingival index (mGI) 2 or 3, P=0.003; 94% vs. 62% subjects who had maximum PD �4 mm, P=0.008; 100% vs. 79% subjects who had BoP, P=0.044; mean PD 3.36±0.66 vs. 2.75±0.66 mm, P=0.002; and sites% with BoP 68±23% vs. 36±31%, P<0.001), as compared with those who had <5% sites with PD�4 mm and <30% sites with BoP on the remaining teeth. The relative risk for subjects with the more severe and extensive periodontal conditions compared to those with better periodontal conditions to have PD�5 mm with BoP at peri-implant sites was 23.3 (P=0.003, 95% CI, 2.8-192.3). Conclusion: The peri-implant conditions were significantly related to the periodontal conditions around the remaining natural teeth, which imply that control of periodontal disease is essential for successful implant treatment.
