Abstract:
Objective · To observe short and medium term survival of implants in patients with chronic periodontitis after implantation. Methods · 54 patients with chronic periodontitis (133 implants) were enrolled from August 2011 to August 2013. The survival of implants was observed and the periimplant diseases were compared and analyzed between patients with different degrees of chronic periodontitis. Results · The 3-year survival rate of implants was 97.74%. The differences between patients with different degrees of chronic periodontitis were not statistically significant (P=0.452). Periodontal pocket depth (PPD) and modified plaque index (mPLI) were significantly higher in patients with severe chronic periodontitis than in patients with mild and moderate chronic periodontitis. For patients not receiving supportive periodontal therapy (SPT), the peri-implantitis rate in patients with severe chronic periodontitis was significantly higher than that in patients with mild and moderate chronic periodontitis (P=0.009). For smokers, the periimplantitis rate in patients with severe chronic periodontitis was significantly higher than that in patients with mild and moderate chronic periodontitis (P=0.016). Conclusion · For patients with chronic periodontitis, the theraputic effect of implant treatment is good. Plaque control, SPT, and smoking cessation can reduce the incidence of peri-implantitis.
