老年患者牙齿残根、残冠的治疗和修复

目的 探讨老年患者牙齿残根、残冠治疗和修复的方法和效果，以提高治疗水平。方法 对68例老年患者202颗牙的残根和47颗牙的残冠拍X线片，了解其残根的长度，残根、残冠的治疗和根尖周状况，进行全面治疗设计，包括完善根管治疗、根面充填、核桩冠以及铸桩修复，或作固定桥基牙。并对修复体的使用及牙周健康状况进行了为期1．5～3年的随访观察。结果 行完善根管治疗，前牙109颗，双尖牙74颗，磨牙26颗，成功率92．3％～94．5％，修复体恢复了功能和美观，没有根面龋。修复治疗的失败率为5．5％～7．7％。核桩冠87颗中1颗根裂，7颗松动2～3度的牙均为活动义齿基牙和独立牙，可能与负担过重和创伤有关。64颗铸桩固定桥中，6颗崩瓷，可能与创伤有关。牙龈炎症主要表现在基牙和独立牙。结论 综合治疗和修复老年患者牙齿的残根、残冠，可以保证牙周健康，并能较好地改善咀嚼功能。

Treatment and restoration of residual dental root and crown in the elderly

Objective To investigate the effect of treatment and restoration of residual dental root and crown in the elderly. Methods A total of 68 elderly patients with 202 residual roots and 47 residual crowns was treated.Radiography was taken to find out the length of residual roots and the status of treatment. A comprehensive treatment plan was made for each case, including restoration, extraction and endodontic treatment, etc. The restoration and the periodontal health of abutment teeth were followed up for 1 5 to 3 years consecutively. Results In endodontically treated teeth, the success rates of anterior 109, bicuspid 74, molar 26, were 92 3% 94 5%. In 87 post core crowns, 1 root cracked, 7 teeth mobility was 2 0 3 0 , all of which were the abutment teeth of removable dentures and single tooth. Maybe it was the impact of load heavy and occlusal trauma. In 64 post core fixed bridges, 6 ceramic broken was the impact of occlusal trauma. The function of restorations was good, with no root caries. Periodontitis was mainly in the abutment teeth and single tooth. Failure rate of restorative was 5 5% 7 7%. Conclusions Comprehensive treatments and restorations for residual root and crowns in the elderly would improve periodontal health and chewing function.
