Introduction: To investigate the influence of implant restoration scheme after routine extraction and site preservation extraction on implant restoration and periodontal status in patients with severe chronic periodontal disease.

Methods: 207 patients with severe chronic periodontal disease admitted to our hospital from January 2017 to January 2021 were included in this study. They were divided into 2 groups, including 127 cases receiving implant restoration scheme after routine extraction (Group A) and 80 cases receiving implant restoration scheme after site preservation extraction (Group B). The implant success rate, excellent and good rates of restoration, periodontal indicators before and after treatment and scores of patients’ subjective assessment scale were compared. 

Results: The implant success rate and excellent and good rates of restoration in Group B were significantly higher than those in Group A (P<0.05). In both groups, the levels of sulcular bleeding index (SBI), probing depth (PD), attachment loss (AL) and plaque index (PLI) 4 weeks after treatment were significantly lower than those before treatment (P<0.05). There were no sig-nificant differences between 2 groups in the levels of sulcular bleeding index and plaque index four weeks after treatment (P>0.05). The levels of probing depth and attachment loss in Group B were significantly lower than those in Group A four weeks after treatment (P<0.05). The scores of chewing function, aesthetics and overall satisfaction in Group B four weeks after treatment were significantly higher than those Group A and before treatment (P<0.05). 

Conclusion: Compared with implant restoration scheme after routine extraction, implant restoration scheme after site preservation extraction can efficiently ameliorate implant restoration and reduce probing depth and attachment loss in patients with severe chronic periodontal disease and help improve the subjective satisfaction of patients
