研究目的:

本研究的目的是在临床上评价采用L形无机骨胶原联合胶原膜(Geistlich Bio-Gide?)的GBR与采用无机牛骨(Geistlich Bio-Oss?)联合胶原膜(Geistlich Bio-Gide?)的GBR在HT0(垂直于种植体肩台长轴的方向)水平骨增加量方面(术后6个月时通过锥形束计算机断层扫描测量)的差异。  

Objectives of Study:

This study is aimed to clinically evaluate whether GBR with L-shape anorganic bone collagen in combination with a collagen membrane (Geistlich Bio-Gide?) differs from GBR with anorganic bovine bone (Geistlich Bio-Oss?) in combination with a collagen membrane (Geistlich Bio-Gide?) in terms of the amount of horizontal bone gain at HT0 (lines perpendicular to the implant's long axis at the implant shoulder) measured by cone-beam computed tomography (CBCT) at 6 months after surgery.

药物成份或治疗方案详述:

正中牙槽嵴切开后,从牙槽嵴顶抬高全层黏骨膜瓣,轻轻清创骨缺损。然后根据生产商的说明,将种植体固定装置(Straumann BL,Straumann Implant)插入理想的义齿位置。试验组受试者将接受采用L形技术的GBR。 使用15号刀片将去蛋白牛骨矿物质C(Geistlich Bio-Oss?胶原,250?mg,Geistlic Pharma AG,Wolhusen,瑞士)适当修剪成L形,并直接应用于开裂缺损处,使软块的内表面与暴露的种植体固定装置的咬合面和颊侧面相匹配。 在颊侧和咬合侧,对种植体周围开裂缺损处进行增量,使缺损处周围的骨壁凸出至少1 mm。随后,使用双层可吸收的天然双层胶原膜(NBCM,Geistlich Bio-Gide? 13×25 mm,Geistlich Pharma AG)覆盖L形DBBM-C。 

Description for medicine or protocol of treatment in detail:

After midcrestal incision, full-thickness mucoperiosteal flaps will be elevated from the alveolar crest, and osseous defects will be gently debrided. Then the implant fixture (Straumann BL, Straumann Implant) will be inserted in the ideal prosthetic position according to the manufacturer's instructions. Participants in the test group will undergo GBR with L-shape technology. Demineralized bovine bone mineral-C (Geistlich Bio-Oss? Collagen 250 mg, Geistlich Pharma AG, Wolhusen, Switzerland) will be appropriately trimmed to an L-shape with a #15 blade and applied directly to the dehiscence defect, fitting the inner surface of the soft block to the occlusal and buccal surfaces of the exposed implant fixture. Peri-implant dehiscence defects will be augmented to achieve a minimum of 1 mm over-contour for the bony wall surrounding the defect, both at the buccal and occlusal aspects. Subsequently, the L-shaped DBBM-C will be covered using a double layer of absorbable native bilayer collagen membrane (NBCM, Geistlich Bio- Gide? 13 × 25 mm, Geistlich Pharma AG).

随机方法(请说明由何人用什么方法产生随机序列):

随机数字用于分组。基本概念为: 1)为入组临床试验的每例受试者生成相应的随机数字。 2)按从小到大(或从大到小)的随机数字排序。 3)根据每个治疗组预设的样本量,以随机数字顺序选择相应的样本量,并分配给不同的治疗组。

Randomization Procedure (please state who generates the random number sequence and by what method):

Random numbers are used for grouping. The basic idea is: 1) Generate a corresponding random number for each subject included in the clinical trial. 2) Sort by random numbers from small to large (or from large to small). 3) According to the preset sample size of each treatment group, select the correspond
