Abstract:
Objective:To evaluate the medium and long term clinical effect of three bone graft materials on periodontitis after periodontal regeneration.Methods:Initially, 16 patients with periodontitis after periodontal regeneration in Tianjin Stomatological Hospital from July 2017 to November 2018 were divided into three groups: Bio-Oss ( n=6), Bio-Gene ( n=5) and Bone 3(n=5) according to the differences in bone materials. Clinical and radiological results were evaluated at pre-surgery, post-6 months, and post-4 years. Results:The 6-month and 4-year clinical follow-up showed that, the depth of exploration (PD) and clinical attachment loss (CAL) of patients in the three groups were lower than those before operation (all P<0.05), and the changes of PD (ΔPD) and CAL (ΔCAL) were not statistically significant (all P>0.05). There was no statistically significant difference in gingival recession (GR) between the three groups (all P>0.05), and there was no statistically significant difference in the change of GR (ΔGR) between the groups (all P>0.05). From 6 months to 4 years after operation, there was no significant difference among ΔGR, ΔPD and ΔCAL groups (all P>0.05). At 6 months and 4 years after operation, the residual alveolar bone height (RBH%) of the three groups was significantly higher than that before operation (all P<0.05), and there was no significant difference between the two groups (all P>0.05); From 6 months to 4 years after operation, there was no significant difference in RBH% between the groups (all P>0.05). Conclusions:Three kinds of bone graft materials have significant clinical effects on periodontitis after periodontal regeneration, which can provide a reference for the selection of clinical regeneration materials.
