Resin restoration of splinted split teeth: a scanning electron microscopic study 劈裂牙结扎后塑化治疗的扫描电镜研究
Most of longitudinal split of teeth occurred in first molars and was usually found in the teeth of nonvital pulp. 牙冠纵向劈裂多见于死髓牙,好发牙位为第一磨牙,且上颌牙多于下颌牙。
【 Methods 】 Thirty-six molars with vertical split were treated by teeth hemisection first, then rigid fixed bridge ( 20 cases) or cantilever fixed bridge ( 12 cases) were used to restore the remaining teeth structures. 【方法】采用牙体半切术切除32例(36颗牙)纵裂牙根,余留牙体分别以单端固定桥修复(12例)和双端固定桥修复(20例)。
Conclusion: The method of restoring seamen's split teeth with metal full crown is very effective, and should be chosen first. 结论:金属全冠对舰艇人员折裂牙的修复非常有效,应作为折裂牙修复之首选。
Objective: To find out the effect of metal full crown in the restoration of seamen's split teeth. 目的:了解金属全冠对舰艇人员折裂牙修复的作用。
Objective To study the clinical possibility and practical range of palliative treatment for split teeth. 目的探讨劈裂牙姑息保留治疗方案广泛应用于临床的可能性及其应用于临床的实际范围。
