Clinical efficacy of implant treatment following alveolar ridge preservation or natural healing in the extraction sockets of molars with severe periodontitis
摘要
Abstract
Objective To observe the clinical efficacy of implant treatment following alveolar ridge preservation in the molar extraction sockets with severe periodontitis and compare it with the natural healing control group.Methods Ten patients with a total of 13 molar extraction sockets with severe periodontitis receiving implant placement following alveolar ridge preservation (6 patients,6 tooth)or natural healing (5 patients,7 tooth)were recruited in Peking University School and Hospital of Stomatology from 2013 to 2016.In a 12-30 months follow-up period,each implant was examined with the following parameters:probing depth,bleeding index,plaque index,papilla index(PI) and food impaction.Parallel periapical radiographs were taken every 6 months to evaluate the peri-implant marginal bone loss.Success rate was defined using the criteria from Karoussis et al (2004).Additionally,each patient completed retrospectively a satisfaction questionnaire using Visual Analog Scale (VAS).Results There was a 100％ survival rate of implants in both groups.The success rate was around 100％ for implants in ridge-preserved sites and around 42.9％ for implants in natural healing sites.There were no statistically significant differences in the BI,PLI or PI between two groups except for the PD(P ＜ 0.05).Marginal bone loss of the implant in both groups at the 12th month after implant loading was ＜1 mm.After the first year of service,annual marginal bone loss did not exceed 0.2 mm in ridge preservation group,the mesial and distal sites were(0.03 ± 0.16)mm and(0.05 ± 0.10)mm on average.All the patients were satisfied with the implant with VAS ≥ 85.There were no statistically significant differences between PI and food impaction.Conclusion Implant placement at ridge-preserved molar sites with severe periodontitis is a predictable procedure resulting in very high survival rates and higher success rates compared to implant placement in natural healing sites.关键词
