This paper describes the combined efforts of an orthodontist, periodontist, and a restorative dentist to save an unrestorable tooth by clinical crown lengthening. A maxillary lateral incisor, originally treatment planned for extraction, was treated with orthodontic extrusion, circumferential fiberotomy, and metal-ceramic crown restoration. To maximize the esthetic appearance of the tooth during orthodontic treatment, an acrylic resin facing was designed together with the orthodontic appliance used to facilitate vertical extrusion. Clinical crown lengthening may be used as an alternative approach to the treatment of severely broken down anterior teeth.
本文描述了一位正畸医生、一位牙周病医生和一位修复牙医共同努力，通过临床牙冠延长术挽救一颗无法修复牙齿的过程。一颗原本计划拔除的上颌侧切牙，接受了正畸牵引、环切纤维切断术和金属烤瓷冠修复治疗。为了在正畸治疗期间使牙齿的美观效果最大化，设计了一种丙烯酸树脂贴面，并与用于促进垂直牵引的正畸矫治器一起使用。临床牙冠延长术可作为治疗严重损坏的前牙的一种替代方法。
