摘要
目的:评价利用髓室固位制作嵌体冠修复磨牙残冠的效果。方法:对61颗磨牙残冠经完善根管治疗后,制作髓室固位的铸造金属嵌体冠,修复完成后,定期进行临床检查,评价修复效果。结果:经过1～5a的随访观察,61颗患牙经过修复治疗后获得满意效果,个别病例出现修复体颈缘密合不良、牙龈炎,或继发龋、食物嵌塞。结论:利用髓室固位的铸造金属嵌体冠治疗磨牙残冠,是一种简单易行、经济实惠、效果良好的修复方法,严格选择适应证以及准确的牙体预备和精确的加工制作,是修复成功的关键。
PURPOSE： To evaluate the effect of casting inlays with pulp chamber retention to restore extensively damaged crowns of molars. METHODS： After root canal treatment, sixty-one extensively damaged molar crowns were restored by casting inlays with pulp chamber retention. All the patients revisited after treatment at regular intervals and routine clinical examinations were performed. RESULTS： During the follow-up period from 1 to 5 years, all the 61 restorations functioned well. However, gingivitis, secondary caries or food impaction due to ill-fitting margins of prosthesis were observed in some cases. CONCLUSIONS： Casting inlays with pulp chamber retention is a simple, economic and effective method to restore extensively damaged crowns of molars. Strict choices of indication, precise preparations of the teeth and well-made prosthesis are the key points for long-term successful restorations.
