Abstract：
Ectopic teeth are an eruption disorder in which teeth are located in anatomical structures where, physiologically, they should not occur. An ectopic tooth is a very rare phenomenon, affecting approximately 0.5% of the canine population, and few descriptions of the treatment of such teeth in dogs can be found in the available literature. This article describes the diagnostic and therapeutic handling of cavities following extraction of ectopic teeth in nine dogs. The cases are subdivided into uncomplicated (when the ectopic tooth was encapsulated in the surrounding connective tissue, without lysis of the bone around the tooth) and complicated (in which, in addition to the presence of the ectopic tooth, a dentigerous cyst had formed). Four cases of complicated ectopic teeth are described in more detail. In this study, special attention was paid not only to the technique of tooth extraction itself but also to the method of securing and healing large bone defects after the extraction using hydroxyapatite curdlan polymer. Owing to the plastic properties of the bone substitute preparation, it was possible to implant the material without enlarging the bone defect created during the tooth extraction. Control radiographs showed features of bone regeneration, and clinical examination at both the early and late stages revealed no postoperative complications.
摘要：
异位牙齿是一种萌出障碍，其中牙齿位于解剖结构中，生理上,他们不应该发生。异位牙齿是一种非常罕见的现象，影响了大约0.5%的犬类人口，在可用的文献中可以找到关于狗的这种牙齿的治疗的描述。本文介绍了九只狗在拔除异位牙齿后的诊断和治疗方法。这些病例被细分为简单的（当异位牙齿被包裹在周围的结缔组织中时，没有溶解牙齿周围的骨头)和复杂的(其中，除了异位牙的存在，形成了牙质囊肿）。更详细地描述了四例复杂的异位牙齿。在这项研究中,不仅要特别注意拔牙技术本身，而且要特别注意使用羟基磷灰石curdlan聚合物在拔牙后固定和愈合大型骨缺损的方法。由于骨替代制剂的塑性特性，可以在不扩大拔牙期间产生的骨缺损的情况下植入材料。对照X光片显示骨再生的特征，早期和晚期的临床检查均未发现术后并发症。
