A service evaluation investigating the composite outcome twelve months after periodontal regenerative surgery

Abstract

Aim: The aim of this study was to explore the relationship between patient- / site- factors and the outcomes of regen in intrabony defects with 12 months follow-up

Material and Method: Clinical, radiographic and intrasurgical measurements were collected prospectively from 248 regenerative/reconstructive periodontal surgeries as part of a service evaluation. Clinical and radiographic outcomes were reassessed 12 months post-surgery.

Results: After twelve months, the results of regenerative periodontal surgery were as follows: 57% of cases achieved pocket closure (PPD ≤ 4 mm), 44% met the composite outcome (CAL gain ≥ 3 mm and pocket closure), and 79% had a post-surgical PPD ≤ 5 mm. The mean clinical attachment level (CAL) gain was 2.8 ± 2.7 mm, with 54% of cases achieving a gain of ≥ 3 mm.

Conclusion: Based on the results of this study and in line with previous published data, regenerative periodontal surgery achieved favourable clinical outcomes, albeit not always predictably. Intrabony defect depth and tooth type seem to influence pocket closure and composite outcome twelve months following regenerative surgery of intrabony defects.
