This case report refers to the esthetic and functional restorations of extensively damaged maxillary central incisors with dental caries in a 32-year-old woman, with the use of posts and crowns made from natural extracted teeth. Proper restoration of such teeth with the use of natural teeth fragments are known as "biological restoration." Biological restorations can be done by using the fragments of the patients own tooth and if that is not available, tooth fragment can be obtained from an extracted tooth. These biological posts and crowns present a low cost option and an alternative technique for the morphofunctional recovery of extensively damaged teeth. There are limitations with the use of natural extracted teeth (homogenous bonding) for restoration such as the difficulty of finding teeth with a similar color and shape as that of the destroyed element, or patient may refuse to accept a tooth fragment from another patient, which prevents execution of the restoration.
本病例报告涉及一名32岁女性上颌中切牙因龋齿而严重受损后的美学和功能修复，采用了天然拔除牙制作的桩和冠。使用天然牙碎片对这类牙齿进行适当修复被称为“生物修复”。生物修复可以使用患者自身牙齿的碎片来完成，如果无法获得自身碎片，也可以从拔除牙中获取牙碎片。这些生物桩和冠为严重受损牙齿的形态功能恢复提供了一种低成本选择和替代技术。使用天然拔除牙（同质粘结）进行修复存在一些局限性，比如难以找到与受损牙颜色和形状相似的牙齿，或者患者可能拒绝接受来自其他患者的牙碎片，这会妨碍修复的实施。
