为达到长期、有效地增加牙槽嵴的高度的目的,一期采用致密多晶羟基磷灰石(hydroxlaplatite HA)植入增高、加宽牙槽嵴,二期手术采用中厚游离皮片移植加深前庭沟。本组病例共7例。按 Block SM 对 HA 植入放射线曲面断层片定点测量的评定方法,牙槽嵴平均增高8mm～10mm。随访3a,无明显吸收。HA 植入配合中厚游离皮片移植,可增高牙槽嵴的有效高度,为义齿修复奠定基础。
In order to achieve a long-term and effective increase of height of alveolar ridge, the first stage is dense hydroxydophoric hydroxyapatite (hydroxlaplatite HA) implants, broaden the alveolar ridge, two-stage surgery with thick free skin graft deepen Vestibule ditch. This group of patients a total of 7 cases. According to the method of Block SM, the method of site-directed measurement of HA implanted radiological surface tomography was evaluated. The average height of alveolar ridge was 8mm ~ 10mm. Follow-up 3a, no significant absorption. HA implantation combined with thick free skin graft, can increase the effective height of alveolar ridge, laying the foundation for the denture repair.
