牙缺失修复不同骨质患者行即刻种植与常规种植临床比较研究

目的比较即刻种植和常规种植在不同骨质牙缺失修复中的近期和远期效果,为临床牙缺失种植提供参考.方法选择牙缺失修复患者96例,以接诊顺位分为两组,单数48例患者为常规修复组,采用常规种植;双数48例患者为即刻修复组,采取即刻种植,比较两组治疗时间,种植后使用Osstell谐振频率分析仪测定种植体稳定性(ISQ值);随访24个月,评价远期效果.结果常规修复组不同类骨质牙缺失患者种植后ISQ值与即刻修复组比较差异无统计学意义(P0.05).即刻修复组Ⅰ,Ⅱ,Ⅲ,Ⅳ类骨质牙缺失患者治疗时间均明显短于常规修复组(P0.05).随访24个月,常规修复组Ⅰ,Ⅱ,Ⅲ,Ⅳ类骨质牙缺失患者种植成功率分别为100%,100%,85.71%,80.0%;即刻修复组种植成功率分别为100%,100%,75.0%,83.33%(P0.05).两组牙齿松动、牙龈红肿、牙周脓肿发生率差异无统计学意义(P0.05).结论即刻种植法修复牙缺失可缩短治疗时间,而且近远期效果与常规种植相当,可用于不同骨质的牙缺失修复.

Clinical Comparative Study on Immediate Implantation and Routine Implantation of Dental Implants in Dental Restorations of Patients with Different Sclerotin

Objective To compare the near-term and long-term effects of immediate implantation and conventional implantation in the treatment of tooth loss of patients with different sclerotin,to provide a reference for the clinical treatment. Method 96 patients with anodontia were selected, and divided into two groups according to their visiting orders,48 patients whose visiting numbers were odd numbers in conventional repair group were treated with the conventional implanting and 48 patients whose numbers were dual in immediate repair group and underwent an immediate implanting,and the treatment time was compared between the two groups. The implant stability ( ISQ) was measured by Osstell resonant frequency analyzer after the implantation,and the long-term effect was evaluated by 24 months. Results There was no significant difference in the ISQ value between the conventional repair group and the immediate repair group (P>0. 05). The treatment time for patients with anodontia and classⅠ,Ⅱ,Ⅲand IV sclerotin in the immediate repair group was significantly shorter than that in the conventional repair group (P<0. 05). The results from the follow-up for 24 months showed that the success rate of implantation of the patients with classⅠ,Ⅱ,ⅢandⅣsclerotin in the conventional repair group was 100%,100%, 85. 71% and 80. 0%,respectively,and that in the immediate repair group was 100%,100%,75. 0%,and 83. 33%, respectively (P>0. 05). There was no significant difference between two groups in the incidence of tooth mobility, swelling of the gums and the incidence of periodontal abscess (P>0. 05). Conclusion Immediate implantation can shorten the treatment time,and the near-term and long-term effect is comparable to that of conventional cultivation. It can be used in the treatment of bone loss with different sclerotin.
