无机牛骨用于牙槽嵴的增高已有多年的历史,本文介绍在口腔颌面外科其它方面的应用并作出评估。 患者与方法 牛骨用乙二胺处理24h即可作为移植块,它不会引起宿主排斥反应。把26个病例依类型分为4组。A组主要包括对先天性发育不全病例的矫正,共7例。无机牛骨的皮质骨塑形后,经口内切口插入骨膜下袋内;1例术后颞肌萎缩并留有颞区凹陷者,通过原双侧冠状切口,将牛骨置于凹陷处,缝合覆盖其上的骨膜以固位;B组,矫正外伤后畸形,共8例。包括:通过口内径路将无机牛骨的皮质骨放在骨膜下增高损伤后的颧骨,并用微型钛板螺钉固位;并采用无
Inorganic bovine bone for the alveolar crest has been increasing for many years, this article describes the other aspects of oral and maxillofacial surgery and make an assessment. Patients and methods Bovine bone treated with ethylenediamine for 24 h can be used as a graft, it will not cause host rejection. The 26 cases were divided into 4 groups by type. Group A mainly includes the correction of congenital hypoplasia cases, a total of 7 cases. Inorganic bovine cortical bone shaping, the endo-incision into the subperiosteal pocket; 1 case of postoperative temporal muscle atrophy and left temporal recess, through the original bilateral coronal incision, the bovine bone placed in depression, suture Cover the periosteum to fix it; Group B, correct traumatic deformities, a total of 8 cases. Including: placing the cortical bone of the inorganic bovine bone in the periosteum to increase the cheekbones after the injury through the intraoral approach and fixing with the mini-titanium plate screws; and adopting
