WEGO种植系统的临床观察

Clinical observation of WEGO implant system

背景:随着种植义齿愈来愈多的应用于口腔修复领域,全球约近千种品牌不同表面处理及平台设计的种植体问世,然而国内已应用于临床的种植系统极少。目的:通过临床试验,观察和评价WEGO种植系统临床应用的安全性和有效性。方法:募集志愿者并经过严格的病例筛选,排除全身及局部禁忌症(血常规、血凝长规、肝肾糖查体等),根据个体条件不同,分别采用埋入式、非埋入式方案,选择60例牙列缺损患者植入喷砂和酸蚀(SLA)表面处理的WEGO种植体60枚,2-4个月行种植修复,三个月血液指标检查,通过临床检查及影像学分析对临床效果进行评价。结果和结论:60例患者植入前后血液指标差异无统计学意义(P<0.05),此种植系统临床安全性可靠。依照Albrektsson等的口腔种植评价标准60枚种植体骨结合良好,留存率100%,成功率100%,宿主无不良反应。种植术后即刻、修复后即刻、植入后1年种植体近中边缘骨高度分别为(0.33±0.45)、(0.14±0.43)、(0.16±0.37)mm;远中边缘骨高度分别为(0.17±0.43)、(0.04±0.49)、(0.11±0.40)mm,种植体植人后第1年颈部骨吸收量近中为(0.16±0.37)mm,远中为(0.04±0.35)mm。结果表明喷砂和酸蚀(SLA)表面处理的WEGO种植系统临床应用安全,修复效果有效。

Background： With denture planting more and more applications in dental restorations, brand around the world nearly one thousand kinds of different surface treatment and platform design of implants, but the domestic is very little cropping system has been applied in clinical. Objective：Through clinical experiment, to observe and evaluate WEGO planting system the safety and efficacy of clinical application. Methods： Volunteers who passed strict screening were selected as study subjects. Systemic and local contraindications were excluded （blood routine, blood clotting and hepatorenal index, etc）. A total of 60 patients who had 60 WEGO implants implanted were followed up for one year. Permanent restorations were finished 2 to 4 months after the implantation. And blood index would be tested again after three months. Clinical effects were evaluated through clinical and imaging examination. Results and Conclusion： There was no statistically significant difference of postoperation blood indexes. So WEGO planting system is safety and reliable in clinical. Clinical effects were evaluated with the Albrektsson＆#39;s criteria. Favorable osseointegration was formed rapidly. Both the survival rate and successful rate of implants were 100%. High degree of satisfaction from patients was achieved. Planting immediately after surgery, immediately after the restoration, 1 year after surgery marginal bone height in nearly is respectively （0.33 ±0.45）, （0.14 ±0.43）, （0.16 ±0.37）mm. Marginal bone height in far is respectively（0.17±0.43）、（0.04±0.49）、（0.11±0.40）mm. The marginal bone loss 1 year after surgery was （0.16 ±0.37）mm in nearly and （0.04 ±0.35）mm in far. WEGO planting system could be considered as a manageable and satisfactory implant system. This system can obviously reduce bone resorption.
