前牙中度或重度牙周病患者常有较明显的深牙周袋。在上颌前牙区,牙周附着的丧失常原于牙周骨垂直性损害。一般牙周病治疗的主要目的是对病损区彻底清创,减少牙周袋深度从而维持良好的口腔卫生。进一步则是在可能的情况下,保护患者牙周组织的美观外形。传统的牙周病损区清创对牙周外形破坏较大,大多数患者难以接受。于此,本文作者介绍了用能诱导骨重建的移植材料(多晶羟基磷灰石微粒)整复垂直病损的牙周骨与能维护牙周组织外形的“关帘”术式(curtain technique)相结合的治疗方法,取得了满意的效果。方法病例选择要求:(1)患者有治疗修复要求;(2)骨缺损窄而深,足以容纳移植材料;(3)
Patients with moderate or severe periodontal disease of the anterior teeth often have more obvious deep periodontal pockets. In the maxillary anterior region, the loss of periodontal attachment often originates from periodontal bone damage. The main purpose of general periodontal disease treatment is to completely debridement of the lesion area, reduce the depth of the periodontal pocket in order to maintain good oral hygiene. Further, it is possible to protect the aesthetic appearance of the patient's periodontal tissue. Dental periodontal debridement of the traditional periodontal shape destruction, the majority of patients unacceptable. Here, the authors describe a technique called “curtain technique” that reconstructs orthodontic lesions with periodontal bone that can maintain the appearance of periodontal tissue with a graft material capable of inducing bone remodeling (polycrystalline hydroxyapatite particles) ) Combined with the treatment, and achieved satisfactory results. Methods Case selection requirements: (1) the patient has the need for treatment and repair; (2) the bone defect narrow and deep enough to accommodate the graft material; (3)
