摘要
目的以复合树脂充填和金属烤瓷全冠修复为对照,研究钴铬合金高嵌体治疗活髓隐裂牙的临床效果。方法将201例患者201颗隐裂牙按照临床症状分为3组:轻微咬合不适组(A组)、轻微咬合痛伴一过性冷热刺激痛组(B组)、咬合痛伴延缓性冷热刺激痛组(C组)。每组患牙分别采用复合树脂充填、钴铬合金高嵌体和金属烤瓷全冠修复。随访2年,观察各组患者治疗的有效率。结果 A组、B组和C组有效率比较,差异有统计学意义(P<0.05);钴铬合金高嵌体和金属烤瓷全冠修复的有效率显著高于复合树脂充填(P<0.05)。结论对于轻微咬合不适和轻微咬合痛伴一过性冷热刺激痛的患牙,钴铬合金高嵌体是有效的修复方法。
Objective To investigate the effect of cobalt chromium alloy onlay on the direct repair of cracked vital pulp teeth with the resin compostie filling and porcelain-fused-to-metal （PFM ） crown repair as the control .Methods 201 cracked vital pulp teeth from 201 cases were randomly divided into 3 groups according to the clinical symptoms ：mild discomfort at occlusion （group A） ,pain at occlusion accompanied with transient pain to cold or hot stimulation （group B） and pain at occlusion accompanied with continuous pain to cold or hot stimulation（group C） .The cracked teeth directly were restored by the resin composite filling ,cobalt chromium alloy onlay and PFM crown repair and the effective rate in each group was observed after 2-year follow up .Results The effective rate of the group A ,B and C were statistically significant different from each other （P〈0 .05） .The effective rate of the co-balt chromium alloy onlay and the PFM crown was statistically significant higher than that of resin composite （P〈0 .05） .Conclusion The direct repair with cobalt chromium alloy onlay is an effective repair method for the cracked vital pulp teeth with mild discomfort at occlusion and mild pain accompanied with transient pain to cold or hot stimulation .
