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.
异位牙是一种萌出障碍，即牙齿位于其在生理情况下不应出现的解剖结构中。异位牙是一种非常罕见的现象，约影响0.5%的犬类种群，在现有文献中很少能找到关于犬类此类牙齿治疗的描述。本文描述了9只犬异位牙拔除后龋洞的诊断和治疗处理。这些病例分为简单型（异位牙被包裹在周围结缔组织中，牙齿周围骨质无溶解）和复杂型（除异位牙外，还形成了含牙囊肿）。详细描述了4例复杂异位牙病例。在本研究中，不仅特别关注拔牙技术本身，还关注拔牙后使用羟基磷灰石-可德兰聚合物固定和愈合大的骨缺损的方法。由于骨替代制剂的可塑性，无需扩大拔牙时造成的骨缺损即可植入材料。对照X光片显示有骨再生特征，早期和晚期的临床检查均未发现术后并发症。
