Captive felids are prone to dental fractures, and the recommended treatment involves endodontics (root canal treatment), prosthodontics (coronal restoration), or tooth extraction. A single-unit dental prosthesis can restore the crown of a tooth whose structure has been partially or completely lost. Nine animals out of 35 captive wild felids kept under human care in 7 different Brazilian institutions were selected for the study. The animals selected included the little spotted cat (), ocelot (), margay cat (), pampas cat (), jaguarundi cat (), puma (), jaguar (), lion (), and tiger (). Nineteen canine prosthodontic crowns (18 full and one 3/4) were cemented using dual-cure resin cement and their feasibility was evaluated for 30 months. Fourteen (73%) remained fixed to the tooth and 5 (27%) were lost after the evaluation period. This study aimed to assess the longevity of prosthodontic crowns in the canine teeth of wild felids. Furthermore, it aimed to determine the functionality and longevity of teeth which had received prosthodontic crowns.
圈养的猫科动物容易出现牙齿骨折，推荐的治疗方法包括牙髓病学（根管治疗）、口腔修复学（牙冠修复）或拔牙。单单位牙齿修复体可以修复结构已部分或完全丧失的牙齿牙冠。从巴西7个不同机构人工饲养的35只圈养野生猫科动物中挑选了9只动物进行研究。所选动物包括小斑虎猫、豹猫、长尾虎猫、潘帕斯猫、美洲草原猫、美洲狮、美洲豹、狮子和老虎。使用双固化树脂水门汀粘结了19个犬齿修复牙冠（18个全冠和1个3/4冠），并对其可行性进行了30个月的评估。评估期结束后，14个（73%）仍固定在牙齿上，5个（27%）脱落。本研究旨在评估野生猫科动物犬齿修复牙冠的使用寿命。此外，还旨在确定接受了修复牙冠的牙齿的功能和使用寿命。
