摘要
目的探讨无牙颌患者经口腔种植修复后种植体不同负重时机对治疗效果的影响,为指导临床工作提供依据。方法回顾性收集2018年9月至2022年9月于广东省第二中医院择期开展种植修复治疗的28例无牙颌牙周炎患者的临床资料,根据术后负重时机不同分为即刻组(n=14,共64枚种植体)、延期组(n=14,共64枚种植体),其中即刻组患者于种植体植入后72 h内安装临时固定修复体;延期组患者于种植体植入后两周安装过渡义齿;两组术后3~6个月行永久修复,比较两组患者的种植成功率、修复体并发症、种植体边缘骨吸收量、患者主观满意度。结果在种植修复完成后12个月随访期间,即刻组患者的种植成功率为96.88%,与延期组的100.00%比较差异无统计学意义(P>0.05);即刻组患者种植修复后12个月修复体并发症发生率为4.17%,明显低于延期组的10.12%,差异有统计学意义(P<0.05);即刻组平均骨吸收量为(0.60±0.10)mm,低于延期组的(0.65±0.11)mm,差异有统计学意义(P<0.05),且同组内上颌骨边缘骨吸收均值均大于下颌骨边缘骨吸收量,差异有统计学意义(P<0.05);即刻组总体满意度评分为(7.88±0.94)分,高于延期组整体满意度评分的(6.89±1.43)分,差异有统计学意义(P<0.05)。结论相较于延期负重,无牙颌患者经种植修复治疗后予以即刻负重修复可有助于提升短期种植成功率,降低骨吸收风险,提升满意度。
Objective To investigate the effects of different implant loading timings on the treatment outcomes of edentulous patients undergoing oral implant restoration,providing evidence for clinical guidance.Methods The clin-ical data of 28 edentulous patients with periodontitis who underwent elective implant restoration at Guangdong Second Traditional Chinese Medicine Hospital from September 2018 to September 2022 were retrospectively collected.Based on the postoperative loading timing,the patients were divided into an immediate loading group(immediate group,n=14,64 implants)and a delayed loading group(delayed group,n=14,64 implants).In the immediate group,temporary fixed prostheses were installed within 72 hours after implant placement,while in the delayed group,transitional dentures were installed two weeks after implant placement.Both groups of patients underwent permanent restoration 3-6 months post-operatively.The implant success rate,prosthetic complications,marginal bone resorption,and patient subjective satisfac-tion were compared between the two groups.Results During the 12-month follow-up after implant restoration,the im-plant success rate in the immediate group was 96.88%,showing no statistically significant difference compared to 100.00%in the delayed group(P>0.05).The incidence of prosthetic complications in the immediate group at 12 months was 4.17%,significantly lower than 10.12%in the delayed group(P<0.05).The average bone resorption in the immedi-ate group was(0.60±0.10)mm,significantly lower than(0.65±0.11)mm in the delayed group(P<0.05).Within each group,the mean marginal bone resorption in the maxilla was greater than that in the mandible(P<0.05).The overall satis-faction score in the immediate group was(7.88±0.94)points,significantly higher than(6.89±1.43)points in the delayed group(P<0.05).Conclusion Compared to delayed loading,immediate loading restoration after implant treatment in edentulous patients can improve short-term implant success rates,reduce the risk of bone resorption,and enhance patient satisfaction.
