摘要
对3例全口无牙颌或重度慢性牙周炎牙列缺损患者术前制作全口义齿或即刻全口义齿,拔除全口余留牙,在下颌植入4颗Ankylos种植体,上颌植入6颗种植体,将SynCone套筒基台接入种植体,再套入预成圆锥形外冠,完成临时义齿修复。3～12个月后将临时义齿更换为铸造支架覆盖义齿。随访12～24个月,除1例种植体在植入后1个月松动拔除而重新植入种植体外,其余种植体均未出现明显的牙槽骨吸收。
Completed denture or immediate completed dentures were manufactured before operation to three patients with edentulous mandible and maxillary or severe chronic periodontitis. The remnant teeth of patients were extracted. Four Ankylos implants were implanted in mandible, and six implants were implanted in maxillary. SynCone conical bases were placed into implants, prefabricated conical crowns were inserted into conical bases, and temporary dentures were completed. After 3-12 months, temporary dentures were replaced by overdenture with casting frame. Except that one implant had been lost and was replaced by a new implant after 1 month of treatment, the rest implants had no obvious frontal resorption in 12-24 months of follow-up.
