A new procedure for apical closure after apical root resection with a metal filling is presented which is easy to handle with appropriately standardized equipment and ensures exact apical closure. By conical preparation of the whole root, a standardized metal peg which resists distortion can be used for anchoring the crown prosthesis without further preparation. Temporarily a standardized guttapercha peg can be used for closure. Even if renewed work on the root becomes necessary later, the apical metal closure remains firm because of its wedging.
本文介绍了一种根尖切除术后用金属充填进行根尖封闭的新方法，该方法使用适当标准化的设备易于操作，并能确保精确的根尖封闭。通过对整个牙根进行锥形预备，可以使用一根抗变形的标准化金属桩，无需进一步预备即可用于固定冠修复体。临时可用标准化的牙胶尖进行封闭。即使之后需要对牙根再次进行操作，根尖的金属封闭由于其楔合作用仍保持牢固。
