Effect of guided bone regeneration on gingival aesthetics and alveolar bone resorption of dental implants in the anterior region

doi:10.19438/j.cjoms.2020.03.009

Abstract

Abstract: PURPOSE: To understand whether guided bone regeneration (GBR) can be used in patients with bone defects at the implantation site in the anesthetic area of the anterior teeth to obtain similar gingival aesthetic effects in patients without obvious bone defects after implantation, and to evaluate the effects of GBR on bone alveolar resorption. METHODS: A total of 31 patients who underwent anterior dental implantation at the Stomatology Center of the First Affiliated Hospital of the University of Science and Technology of China (Anhui Provincial Hospital) from August 2017 to June 2018 were selected. The width of the alveolar bone at the implantation site was measured in all 31 patients before surgery. The patients with a width of less than 6.8 mm were in the GBR group, and the patients with a width of more than 6.8 mm were in the non-GBR group. The two groups of patients were compared for gingival esthetic score, probing depth and alveolar bone resorption during the second-stage restoration. SPSS 19.0 software package was used to perform two independent sample t tests on the data. RESULTS: The gingival aesthetic score of the GBR group was significantly higher than that of the non-GBR group(P<0.01). There was no significant difference in the probing depth between the GBR group and the non-GBR group(P>0.05). Alveolar bone resorption in the GBR group was significantly smaller than that in the non-GBR group(P<0.01). CONCLUSIONS: The use of GBR can slow down the rate of bone resorption and make the patients with local alveolar bone defect reach the similar aesthetic effect of patients without alveolar bone defect after dental implantation.
