牙齿缺失后牙槽嵴吸收萎缩给义齿修复造成困难,近年来多采用羟基磷灰石植入整复牙槽嵴。我院自1988年起使用羟基磷灰石颗粒植入牙槽窝配合即刻义齿修复治疗60例,效果满意,现报告如下。本组60例中男42例,女18例,年龄39～64岁。平均53岁,因牙周病拔牙48例,因龋病拔牙12例。拔牙总数738颗,其中上颌牙425颗,下颌牙313颗,人均拔牙12.3颗。总义齿45例,失牙多的局部义齿15例。种植材料为直径1mm致密多晶羟基磷灰石颗粒(华西医科大学口腔医学院和四川大学研制)。
Loss of teeth after alveolar ridge absorption atrophy to the denture repair difficult, in recent years more use of hydroxyapatite implants alveolar ridge. Our hospital since 1988 using hydroxyapatite particles implanted alveolar nest with immediate denture repair treatment of 60 cases, the results are satisfactory, are as follows. The group of 60 patients, 42 males and 18 females, aged 39 to 64 years. Average 53 years old, 48 cases of periodontal extraction, 12 cases of dental extraction due to dental caries. Tooth extraction total 738, of which 425 maxillary teeth, mandibular teeth 313, per capita extraction of 12.3. 45 cases of total denture, partial dentures with more teeth loss in 15 cases. The planting material is 1mm in diameter polycrystalline hydroxyapatite particles (developed by Huaxi Medical University School of Stomatology and Sichuan University).
