种植体表面粗糙度引导成骨细胞趋化及骨结合的效应:Straumann种植系统临床应用

背景:作为非潜入式种植系统的代表,Straumann种植系统较潜入式种植系统操作简单、无需二次手术,更易被患者接受.目的:观察经喷砂酸蚀表面处理的非潜入式种植体Straumann种植系统对牙列缺损或缺失的修复效果.方法:选择2007-06/2009-06就诊于青岛大学医学院附属医院口腔种植中心使用Straumann种植系统修复的患者124例,排除全身及局部禁忌证,依据不同情况,分别采用常规术式、即刻种植、引导骨再生技术、不翻瓣种植等方案植入218枚种植体,随访观察3～24个月.依照Albrektsson等的口腔种植评价标准对临床效果进行评价.结果与结论:218枚种植体均未见松动、脱落和植入体根周X射线透射区,留存率100%,成功率100%,患者满意度高.经大颗粒喷砂后酸蚀处理的种植体表面粗糙度更有利于引导成骨细胞趋化,加速骨结合.提示Straumann种植体是一种临床操作方便、疗效满意的非潜入式种植体.

Effect of dental implant surface roughness on guiding osteoblasts chemotaxis and osseointegration: Clinical application of Straumann implant system

BACKGROUND: As a new-type and effective restoration means of dentition defect and edentulous,implant denture is a restoration method most closely related to natural teeth,and is accepted by more and more patients.OBJECTIVE: To investigate the clinical effects of non-submerged dental implants with sandblasted and acid-etched surface preparation(Straumann implants system).METHODS: Patients who visited Oral Implantology Center of the Affiliated Hospital of Qingdao University Medical College from June 2007 to June 2009 were selected as study subjects.Systemic and local contraindications were excluded.A total of 124patients who had 218 Straumann implants implanted were followed up for 3 to 24 months.According to various patients' conditions,conventional approach,immediately implanted,GBR technique and flapless operation were adopted respectively.Clinical effects were evaluated with the Albrektsson's criteria.RESULTS AND CONCLUSION: There was no implant loosen,shedding or X-ray transmission in 218 implants.Both the survival rate and successful rate of implants were 100%.High degree of satisfaction from patients was achieved.Straumann implants system could be considered as a manageable and satisfactory non-submerged implant system.
