Giant pandas have a high incidence of tooth wear, loss, and fracture since their diet is specifically bamboo. Dental implantation is a common treatment for tooth loss in humans while rarely reported in wild animals. To explore the applicability of dental implantation in giant pandas, this study measured mandible parameters of the giant panda, from an adult skeletal specimen. The mandible bone block model was developed using computer-aided design 3D mechanical drawing software. Implants of different radius and thread types of the third premolar tooth (PM3) were assembled and imported into an analysis software system for finite element analysis. As a result, the reverse buttress implant with a radius of 7.5 mm and 8.3 mm, and a length of 15 mm was found to be the most suitable implant for use in the giant panda PM3. This study provides a reference for appropriate clinical giant panda dental implantation, although, the feasibility of giant panda dental implantation needs to be studied further.
由于大熊猫的饮食主要是竹子，它们牙齿磨损、脱落和骨折的发生率很高。牙齿植入是人类牙齿缺失的常见治疗方法，而在野生动物中很少有报道。为了探索牙齿植入在大熊猫中的适用性，本研究从一个成年骨骼标本中测量了大熊猫的下颌骨参数。使用计算机辅助设计3D机械绘图软件建立了下颌骨块模型。将不同半径和螺纹类型的第三前磨牙（PM3）植入物进行组装，并导入分析软件系统进行有限元分析。结果发现，半径为7.5 mm和8.3 mm、长度为15 mm的反向支撑植入物是最适合用于大熊猫PM3的植入物。本研究为大熊猫适当的临床牙齿植入提供了参考，不过，大熊猫牙齿植入的可行性还需要进一步研究。
