研究设计:

半随机对照 

Study design:

Quasi-randomized controlled 

研究目的:

(1)评价后牙区两种位点保存术后软组织在组织学和形态学上的差异; (2)评价两种位点保存术牙槽嵴的水平向和垂直向骨量的变化及其成骨的效果。  

Objectives of Study:

(1) Evaluate the histological and morphological differences of the soft tissue after two socket preservation in posterior teeth. (2) Evaluate the changes of bone mass in horizontal and vertical direction and the osteogenic effect of alveolar ridge preservation at two sites.

药物成份或治疗方案详述:

在局麻下使用微创拔牙挺挺松患牙,微创拔除患牙,尽量减少拔牙过程中对牙槽骨壁的损伤。 CGF组:患牙微创拔除后,分离颊侧或舌侧的结缔组织,仔细清理牙槽窝,并用激光处理拔牙窝创面,搔刮牙槽窝使其充满新鲜血液,填入 Bio-Oss骨粉至高度略平于牙槽骨顶,表面覆盖CGF膜,局部减张,拉拢缝合。 Bio-collagen组:患牙拔除后,仔细清理牙槽窝,并用激光处理拔牙窝创面,搔刮牙槽窝使其充满新鲜血液,填入Bio-Oss骨粉至高度略低于牙槽骨顶,bio-oss骨粉颗粒上表面覆盖Bio-oss collagen,采用交叉褥式缝合拉拢缝合。 

Description for medicine or protocol of treatment in detail:

Extract the teeth as minimally invasive as possible under the anesthesia, try to protect the alveolar. CGF group: after tooth extraction, separate the buccal or lingual flap, then clear the tooth socket carefully. Finally clear the socket with laser. After the socket is free from inflammatory granulation tissue. Fill the socket fully with Bio-OSS, and with its surface covered with CGF membrane, then close the wound with modified horizontal mattress. Bio collagen group: after tooth extraction, separate the buccal or lingual flap, then clear the tooth socket carefully. Finally clear the socket with laser. After the socket is free from inflammatory granulation tissue. Fill the socket fully with Bio-OSS, and with its surface covered with Bio-collagen, then close the wound with modified horizontal mattress.
