目的观察慢性牙周炎患者行种植修复后中短期内的种植体存活情况。方法 52例行种植修复慢性牙周炎患者,分为轻度组(13例,种植体25个)、中度组(30例,种植体85个)以及重度组(9例,种植体20个)。比较三组种植修复后3年的种植体存活情况及种植体周围炎发生情况。结果 52例患者种植修复后3年种植体存活率为97.7%(127/130)。三组种植体存活率比较差异无统计学意义(P>0.05);重度组种植体周围炎发生率高于轻度组、中度组,差异具有统计学意义(P<0.05);在非定期牙周支持治疗(SPT)中,重度组种植体周围炎发生率显著高于轻度组、中度组,差异具有统计学意义(P<0.05)。结论慢性牙周炎行种植修复,在中短期内种植体存活率较高,定期行牙周支持治疗、积极控制菌斑使牙周炎程度减轻可降低种植体周围炎发生率。
Objective To observe the survival of patients with chronic periodontitis in the short and medium term after implantation. Methods Fifty-two patients with chronic periodontitis were routinely repaired and divided into mild group (13 cases, 25 implants), moderate group (30 cases, 85 implants) and severe group (9 cases, 20 implants ). The survival of implants and peri-implantitis after 3-year implants implantation were compared between the three groups. Results The survival rate of three-year implants in 52 patients after implantation was 97.7% (127/130). There was no significant difference in the survival rate among the three groups (P> 0.05). The incidence of peri-implantitis in severe group was higher than that in mild group and moderate group (P <0.05) In periodontal support treatment (SPT), the incidence of peri-implantitis in severe group was significantly higher than that in mild group and moderate group (P <0.05). CONCLUSIONS: Chronic periodontitis is implanted and repaired in a relatively short period of time. The survival rate of the implants is high in the short and medium term. Regular periodontal supportive treatment of the periodontitis can reduce the periodontitis and reduce the incidence of peri-implantitis.
