材料和方法 临床收集24例X光片上有一对或几对相似的牙周垂直或角形骨缺损的患者作为研究对象,其中男性11例,女性13例,年龄最大为50岁,最小为21岁,所有患者排除系统性疾病,颞颌关节病和偏侧咀嚼习惯。 术前处理:每位患者初诊时拍摄X光片记录菌斑指数(PLI),龈炎指数(GI),测量牙周袋深度,龈退缩程度,并行龈上洁治,龈下刮治,碘氧冲洗、调(牙合)、口腔卫生指导及用1:5000洗必太液漱口,待龈炎指数和菌斑指数控制在Ⅰ度以下后,测量患牙(牙合)力值,然后随机选择成对牙周骨缺损的患牙之一为实验组,另一为对照组,准备手术。(牙合)力是采用MOF-Ⅰ型(牙合)力微机测定系统进行检测的[3]。测定之前,对患者说明测试要
Materials and Methods Clinically, 24 patients with one or more pairs of vertical or angular periodontal defects with normal or angular periodontal defects were collected, including 11 males and 13 females, the oldest was 50 years old and the youngest was 21 years old. All patients ruled out systemic disease, temporomandibular joint disease and unilateral chewing habits. Preoperative treatment: X-ray film plaque index (PLI), gingivitis index (GI) were recorded at the time of first visit of each patient, the depth of periodontal pockets, the degree of gingival recession, parallel gingival scaling, subgingival scaling, iodine Oxygen flushing, adjusting (occlusion), oral hygiene guidance and 1: 5000 wash too fluid gargle, to be gingivitis index and plaque index control in Ⅰ below the following, measuring teeth (occlusal) force value, and then One of the teeth randomly selected from the paired periodontal defects was the experimental group and the other one was the control group, which was ready for surgery. (Occlusal) force is the use of MOF-Ⅰ (occlusal) force microcomputer detection system for detection [3]. Before testing, test the patient
