Linguoversion of deciduous mandibular canine teeth can be a painful condition, interferes with the development and growth of the jaws, and potentially leads to further malocclusions affecting permanent dentition. Extraction of linguoverted deciduous mandibular canines is considered an interceptive orthodontic procedure that would allow unimpeded development of the jaws and permanent teeth. This study assessed clinical records of 124 dogs that had linguoverted deciduous mandibular canine teeth surgically extracted between October 2010 and September 2019 in a veterinary dental referral clinic. Seventy-seven cases fulfilled the study criteria. Fifty-one percent of these patients required further orthodontic treatment of the permanent occlusion and forty-nine percent demonstrated atraumatic permanent occlusion. The study found no correlation of the outcome with age at the time of surgery. The class of malocclusion (class 1 or class 2) at the time of surgery was also not associated with the outcome.
乳下恒前牙舌侧错位可能是一种疼痛的病症,会干扰颌骨的发育和生长,并可能导致进一步的错颌畸形影响恒牙。拔除乳下恒前牙被认为是一种阻断性正畸治疗,可以允许颌骨和恒牙不受阻碍地发育。本研究评估了 2010 年 10 月至 2019 年 9 月期间在一家兽医牙科转诊诊所接受手术拔除乳下恒前牙的 124 只狗的临床记录。77 例符合研究标准。其中 51%的患者需要对恒牙咬合进行进一步的正畸治疗,49%的患者表现出无创伤性的恒牙咬合。研究发现手术时的年龄与结果之间没有相关性。手术时的错颌畸形(1 类或 2 类)也与结果无关。
