An implant-supported crown represents an established and validated option for single-tooth replacement; however, a restorative solution should be selected according to a wide number of factors including patient's desire, expectations, specific clinical conditions, and financial possibilities. The aim of this case report is to describe a conservative rehabilitation strategy for the replacement of a periodontally compromised mandibular incisor: the extracted natural tooth was used as a pontic bonded to adjacent elements with polyethylene fiber and resin composite. This way, a chairside fabrication of a resin-bonded fiber-reinforced prosthesis is possible, using the patient's own tooth. After showing a satisfactory functional and esthetic result, advantages and pitfalls of this technique along with available data on the literature regarding the natural tooth pontic are addressed. Both patients and clinicians should be aware of minimally invasive, successful solutions for single-tooth replacement; whether indicated or necessary, the natural tooth pontic technique leaves open other treatment options for the future.
种植体支持的冠修复是一种成熟且经过验证的单颗牙缺失修复选择；然而，应根据众多因素选择修复方案，包括患者的意愿、期望、特定临床情况和经济状况。本病例报告的目的是描述一种用于替换牙周状况不佳的下颌切牙的保守修复策略：将拔除的天然牙用作桥体，通过聚乙烯纤维和树脂复合材料与相邻牙体相连。这样，利用患者自身牙齿，在椅旁即可制作树脂粘结纤维增强修复体。在展示了令人满意的功能和美学效果后，讨论了该技术的优缺点以及文献中关于天然牙桥体的现有数据。患者和临床医生都应了解单颗牙缺失的微创、成功修复方案；无论是否适用或必要，天然牙桥体技术都为未来留下了其他治疗选择。
