To change a maxillary lateral incisor into a central incisor by using a ceramo-metallic crown, it is required to schedule a rational plan of treatment. All the different pre-prosthetic (orthodontic, periodontic, and endodontic) and prosthetic steps are described and justified. In order to achieve a compromise between esthetic and a stable periodontium the mesial profile of emergence of the ceramic should be conceived to prevent any overcontour.
使用金属烤瓷冠将上颌侧切牙改造成中切牙时,需要制定合理的治疗计划。文中描述并论证了所有不同的修复前(正畸、牙周和牙髓)及修复步骤。为了在美观和稳定的牙周组织之间达成妥协,应设计陶瓷边缘的近中外形,以防止出现任何外形过度突出的情况。
