The objective of this study was to compare the effects of using short and continuous fibres for repairing compression-induced tooth crown damage. Human teeth were used for the study. They were upper medial incisors and maxillary first premolars lost due to periodontal causes. The teeth were divided into two groups with Hahnenkratt and short glass fibres. Teeth compressive strength tests were carried out. Then micro-CT imaging of the teeth and their fractures obtained after compression was performed. The teeth restored with Hahnenkratt's glass fibre posts showed higher compressive strength than the teeth restored using the EverX Posterior material. The tooth's most weakened and sensitive point after endodontic treatment was the cervical area of the tooth. All cracks were parallel to the root canal.
本研究旨在比较使用短纤维和连续纤维修复因压缩导致的牙冠损伤的效果。研究采用人类牙齿，即因牙周原因缺失的上颌中切牙和上颌第一前磨牙。将牙齿分为 Hahnenkratt 和短玻璃纤维两组。对牙齿进行抗压强度测试，然后对牙齿及其压缩后的骨折进行微 CT 成像。用 Hahnenkratt 玻璃纤维桩修复的牙齿的抗压强度高于用 EverX Posterior 材料修复的牙齿。根管治疗后牙齿最脆弱和敏感的部位是牙齿的颈部。所有的裂缝都与根管平行。
