已经证实羟磷灰石是一种有高度组织相容性的亲骨性材料。作者从1978年以来曾用数种方法作牙槽峭增高200余例,虽有较好效果,但有些缺点仍难以克服,于是设计了本术式。方法:在离牙槽嵴顶部约3cm,从一侧磨牙后区至另一侧磨牙后区的唇颊粘膜上作一弧形切口。用小弯剪仔细在粘膜下分离,直达牙槽嵴顶,以形成一全厚粘膜瓣。骨膜瓣的形成是沿牙槽嵴项全长作直达骨面的切开。在牙槽后部之骨膜瓣向外侧翻开可到外斜线,而牙槽前部的翻瓣则依病人下颌牙槽嵴吸收的程度有所不同。在严重骨萎缩病例(Ⅲ、Ⅳ度骨吸收),骨膜瓣同粘膜瓣一样均 Hydroxyapatite has been shown to be a highly histocompatible, bone-friendly material. The author has used several methods since 1978 to alveolar height more than 200 cases, although better results, but some of the shortcomings are still difficult to overcome, so the design of this technique. METHODS: An arc-shaped incision was made in the labial buccal mucosa at a distance of about 3 cm from the top of the alveolar ridge from the posterior region of the molars to the posterior region of the molars. With a small bend carefully submucosal separation, direct alveolar crest, to form a full thickness mucosal flap. The formation of periosteal flap along the alveolar ridges item length for direct bone surface incision. In the back of the alveolar calf flap open to the outside to the external diagonal, while the anterior alveolar flap according to the patient's mandibular alveolar ridge absorbed to varying degrees. In severe cases of bone atrophy (Ⅲ, Ⅳ degree of bone resorption), the periosteal flap with the same mucosal flap
