下颌前牙区种植修复的临床应用研究

Abstract

Abstract: [Abstract] Objective To investigate the clinical effect of implant prosthesis in mandibular anterior teeth. Methods 60 patients with mandibular anterior teeth implanted in our hospital from February 2013 to August 2017 were selected as the research objects. According to the conditions and indications of the implant area, the control group and the experimental group were set up, 30 cases in each group. Immediate implantation was performed in the experimental group and selective implantation in the control group. The periodontal tissues of the two groups were compared after restoration [improved gingival sulcus bleeding index (mBI), probing depth (PD) and marginal bone resorption (MBL)]. The aesthetic effects of the two groups were evaluated by red aesthetic index (PES). The implant retention of the two groups was monitored one year after restoration. Results There was no significant difference in the mBI index between the experimental group and the control group at 1, 6 and 12 months after repair (p > 0.05, no statistical significance); there was no significant difference in the PD value between the experimental group and the control group at 1, 6 and 12 months after repair (p > 0.05, no statistical significance); the MBL value of the experimental group at 1, 6 and 12 months after repair (0.37±0.11 mm, 0.52±0.13 mm, 0.54±0.17 mm) was significantly lower than that of the control group. Group (0.65±0.12, 0.93±0.19, 0.85±0.33 mm), the difference was statistically significant (p < 0.05). The PES scores of (+ aesthetic effect in the experimental group (9.19±1.32, 9.86±1.02, 10.04±1.14) were significantly higher than those in the control group (7.27±1.63, 8.63±1.37, 8.02±1.25), and the difference was statistically significant (p < 0.05). There was no significant difference in the implant retention rate (93.75%) between the experimental group and the control group (93.55%) one year after restoration (p > 0.05). Conclusion Immediate implantation in mandibular anterior teeth can effectively reduce bone resorption and improve aesthetic effect, and has no significant impact on periodontal tissue and implant retention. It can be the preferred method for implant restoration in mandibular anterior teeth.
