替代吸收率是一个可变的过程，它取决于年龄、基础代谢率、牙槽外时间、再植前的治疗、根部牙本质的数量、创伤的严重程度和牙周膜坏死的程度。在7-16岁的患者中，牙齿在牙根吸收开始后3-7年内丢失。儿童恒切牙强直可能导致的并发症是由于不可避免的创伤牙齿的早期丢失和牙槽骨发育的局部停滞。强直的牙齿应该在变化变得如此明显之前被移除，以免影响未来的修复治疗。治疗方案可能包括：截断性再生治疗、早期拔除强直牙、正畸间隙关闭、故意再植、拔除强直牙齿后立即加高/保留牙槽骨、自体移植、单牙齿骨截骨术和去冠术。本文的目的是回顾在使用去结缔组织技术治疗被诊断为强直的恒切牙的决策中所涉及的考虑因素。
Replacement resorption rate is a variable process, and is dependent on age, basal metabolic rate, extra-alveolar time, treatment prior to replantation, amount of root dentin, severity of trauma, and extent of periodontal ligament necrosis. In patients 7-16 years old a tooth is lost 3-7 years after the onset of root resorption. The complications that may develop as a consequence of ankylosis of a permanent incisor in children are due to the inevitable early loss of the traumatized tooth and local arrest of alveolar bone development. An ankylosed tooth should be removed before the changes become so pronounced that they compromise future prosthetic treatment. The treatment options may involve: interceptive regenerative treatment, early extraction of the ankylosed tooth, orthodontic space closure, intentional replantation, extraction of the ankylosed tooth followed with immediate ridge augmentation/preservation, auto-transplantation, single tooth dento-osseous osteotomy, and decoronation. The purpose of this article was to review the considerations involved in the decision-making concerning the use of the decoronation technique for the treatment of a permanent incisor diagnosed as ankylosed.
