目的观察评价球帽式附着体固位结构在全颌种植体支持覆盖义齿修复中的临床效果。方法收集上下颌重度牙槽骨吸收的无牙颌患者6例,分别在在尖牙区或前磨牙区种植2颗种植体,4月后应用球帽式附着体作为固位结构行上下颌覆盖式总义齿修复,义齿戴入后1周、1月、6月,每12月进行随访观察,平均观察24月,评价患者的满意度,观察种植体周围软硬组织健康状况及义齿机械并发症。结果 6例患者在24个月的随访期内对义齿满意度均高于原来使用的总义齿,24颗种植体周围骨结合良好,球基台周围粘膜健康,义齿完好,无重衬及折断现象发生,除2颗球基台金质球帽磨损,固位力下降,更换球帽后固位力恢复。结论对于重度牙槽骨吸收萎缩的无牙颌患者,在依从性良好,身体及经济状况允许的情况下,球帽式附着体固位的覆盖义齿修复是一种理想的修复方法。
Objective To evaluate the clinical effect of the ball-cap attachment retention structure in the repair of overdenture with all-jaw implants. Methods Six cases of edentulous patients with maxillary and mandibular alveolar bone resorption were collected. Two implants were implanted in the canine or premolar area respectively. After April, the ball and cap attachment was used as the retention structure for mandibular and mandibular coverage The total denture was repaired and the denture was put in for 1 week, 1 month, 6 months and 12 months respectively. The patients were followed up for 24 months on average. The patients’ satisfaction was evaluated. The mechanical and mechanical complications of the soft and hard tissue around the implant were observed. . Results Six patients were satisfied with the denture at the 24-month follow-up period. The periosteum around the 24 implants was good, the mucosa around the ball abutment was healthy, the denture was intact, no reunion and fracture were found Occurred, in addition to 2 ball base ball cap wear, retention decreased, the replacement of the ball cap retention after the restoration. Conclusion For edentulous jaw patients with severe atrophy of the alveolar bone, the overdenture repair with ball-cap attachment retention is an ideal method to repair patients with good compliance and physical and economic conditions.
