Abstract

Abstract: PURPOSE: To compare the clinical effect of erythritol air-polishing and carbon fiber ultrasound working tip for peri-implant maintenance. METHODS: Seventy patients with single implant repair in Beijing Dongcheng District Chongwen Stomatological Hospital were randomly divided into erythritol air-polishing group(group A) and carbon fiber ultrasound working tip group(group B), with 35 cases in each group. Peri-implant maintenance was performed at 3, 6, 12 and 18 months after restoration, and the modified plaque index(mPLI), modified bleeding index(mSBI) and depth of investigation (PD) were measured immediately (baseline) and 3, 6, 12 and 18 months after restoration, respectively. Visual analogue scale(VAS) was used to evaluate the treatment comfort of patients. SPSS 17.0 software package was used for statistical analysis of the data. RESULTS: At 18 months after implant restoration, the incidence of peri-implant mucositis in group A was significantly lower than that in group B(P<0.05). The mPLI and mSBI at 3, 6, 12 and 18 months after implant restoration were increased compared with baseline(P<0.05), but there was no significant difference between the two groups(P>0.05). In both groups, there was no significant difference in PD at different periods after implant restoration compare with baseline. VAS score of treatment comfort in group A was significantly lower than that in group B(P<0.05). CONCLUSIONS: Erythritol air-polishing can be used during peri-implant maintenance phase with higher patient comfort.
