摘要

A search of the medical and dental records at Evidensia L?renskog Dyreklinikk, in L?renskog, Norway, was conducted to identify dogs that received temporary crown extensions (TCEs) to correct linguoverted mandibular canine (LMC) teeth over a 54-month investigation period (2012-2016). Criteria for inclusion into the study were the presence of complete medical and dental records, pre- and postoperative clinical photographs and intraoral radiographs of the affected canine teeth, adequate information pertaining to the procedures performed, and at least 1 follow-up >3 months after appliance removal. Seventy-two dogs with LMC teeth were treated with TCE. Thirty-nine breeds were represented in this study. Mean age at the time of appliance installation was 6.4 (range, 4.7-13.4 months [median, 5.9 months] months). Fifty-three (73.6%) dogs presented with class I malocclusion, 14 (19.5%) dogs with class II malocclusion, and 5 (6.9%) dogs with class III malocclusion. Twenty-five (34.7%) dogs were considered to have mild, 32 (44.4%) dogs to have moderate, and 15 (20.8%) dogs to have severe mandibular canine malocclusion. The TCE was combined with other treatment modalities (active orthodontics, extraction of nonstrategic teeth, gingivectomy, and inclined bite plane and ball therapy) to correct mandibular canine tooth malocclusions in 19 (26.4%) dogs. Fractured or detached crown extensions were seen in 9 (12.5%) dogs. Soft tissue ulceration or inflammation was seen in 7 (9.7%) dogs. The mandibular canine teeth occlusion resolved completely with self-retaining, functional, nontraumatic occlusion in 56 (77.8%) dogs. Fifteen dogs (20.8%) resolved with functional, nontraumatic occlusion, but the mandibular canine teeth were too short to be perfectly self-retained, thus left with 1- to 2-mm crown extensions for permanent retention. In 1 (1.4%) dog, both mandibular canine teeth relapsed almost back to original position. The results show that TCE is a viable treatment option to correct LMC teeth in young dogs.
