Abstract

Abstract: Objective: To evaluate the effects of implants following minimally invasive extraction and minimal flap in ridge preservation at molar extraction sockets with severe periodontitis after 1 year load. Methods: Eighteen patients with a total of 20 molar extraction sockets were recruited in the study from January 2015 to January 2017. At 1-month (baseline) and 1-year post-load,each implant was examined with the following parameters: plaque index (Silness & Leo Plaque Index,PLI), peri-implant probing depth (PPD), bleeding index (Mazza,BI), and width of keratinized tissue (KTW). Parallel periapical radiographs were taken at baseline and 1-year post-load to evaluate the peri-implant marginal bone loss (MBL). Results: The survival rate and success rate were 100% for 20 implants. There were no statistically significant differences in the PLI, PPD, BI, and KTW between baseline and 1-year post-load (P>0.05). MBL was (0.12±0.24) mm(P>0.05). Conclusion: The clinical outcomes of implant restoration were favorable following minimal flap and ridge preservation at molar extraction sockets with severe periodontitis after 1-year load.
