牙周骨移植术成败的关键除了取决于材料的来源、颗粒大小和抗原性处理等技术外,移植材料在骨缺损区固位的优劣也是一个不容忽视的重要环节。因此,选择适当的手术方法使移植材料在骨缺损区良好固位对提高疗效具有重要的临床意义。本文采用常规翻瓣(24个手术区)和有关学者报道的龈乳头保留翻瓣(18个手术区)施行牙周骨移植手术,并取得了较好的效果,现将结果报告如下。材料和方法一、患者的选择和分组选择确诊为不同类型的牙周病患者34人,其中男16人,女18人,年龄16～46岁。所有患者口内至少有
The key to the success or failure of periodontal bone graft depends on the source of the material, the particle size and the antigenicity of the technique. The advantages and disadvantages of the retention of the graft material in the defect area of the bone are also an important aspect that can not be ignored. Therefore, the choice of appropriate surgical methods so that a good graft material in the bone defect retention has important clinical significance to improve the curative effect. In this paper, the use of conventional flap (24 operating area) and reported by scholars to retain flap flap (18 operating area) periodontal bone graft surgery, and achieved good results, the results are reported as follows. Materials and methods First, the patient's choice and group selection of patients diagnosed with different types of periodontal disease 34 people, including 16 males and 18 females, aged 16 to 46 years.
