目的研究应用金属烤瓷和铸造桩核修复牙列缺损及残根残冠，并对其优点和临床操作出现的问题和处理方法进行探讨。方法３５２例１２１９个牙齿采用金属烤瓷修复体进行修复。金属烤瓷固定桥２６９件，其中固位体７８６个，桥体３５０个，金属烤瓷套冠８３个，半口固定义齿１３件，全口固定义齿９副，牙根铸造桩核１０１个。经３个月～１．５ａ随访到３４３例。结果优者３０４例，占８８．６３％，良者２５例，占７．２９％，差者１４例，占４．０８％。结论金属烤瓷修复体不仅能达到外形自然、逼真，而且坚固耐用，咀嚼功能良好，是目前理想的固定修复方法。不但适用于牙列缺损的固定修复，而且适用于残根残冠的保存治疗和错畸形的修复性矫正治疗，具有较高的临床应用价值。
Objective To study the application of metal porcelain and cast post to repair dentition defect and residual root crown, and to discuss its advantages and problems in clinical practice. Methods 352 patients (1219 teeth) were repaired by metal porcelain restoration. There were 269 metal porcelain fixed bridges, including 786 retainers, 350 pontics, 83 porcelain crowns, 13 half-denture dentures, 9 full-denture dentures, and 101 dental cast post cores. After 3 months ~ 1.5a follow-up to 343 cases. The results were excellent in 304 cases, accounting for 88.63%, good in 25 cases, accounting for 7.29%, poor in 14 cases, accounting for 4.08%. Conclusion Metal-ceramic restoration can not only achieve the natural appearance, lifelikeness, but also be durable and have good chewing function. It is the ideal method of fixed restoration at present. Not only for fixed dentition defect repair, but also for the preservation of the residual root crown and the correction of the wrong correction of deformity treatment, has a high clinical value.
