A predictable aesthetic restoration is not limited to the restored teeth; it has to include the gingival unit and its interface with the teeth involved. Orthodontic forced eruption may be a suitable approach without risking the aesthetic appearance in tooth fracture below the gingival attachment or alveolar bone crest. It is a well-documented clinical method for altering the relation between a non-restorable tooth and its attachment apparatus, elevating sound tooth material from within the alveolar socket to create a ferrule effect which is considered to be crucial for the optimal biomechanical behaviour of restored teeth. This report presents the reconstruction of a traumatised and fractured left maxillary lateral incisor by building a cast core with a cast post to perform orthodontic extrusion before placing porcelain fused to metal crown as the final restoration.
可预测的美学修复并不局限于修复的牙齿;它必须包括牙龈单位及其与相关牙齿的界面。正畸强制萌出可能是一种合适的方法,不会对牙龈附着或牙槽嵴下方的牙齿骨折的美学外观造成风险。这是一种有充分文献记载的临床方法,用于改变无法修复的牙齿与其附着装置之间的关系,从牙槽窝内提升健康的牙齿材料以产生箍效应,这被认为对修复牙齿的最佳生物力学行为至关重要。本报告介绍了通过制作带铸造桩的铸造核来重建创伤性骨折的左上颌侧切牙,在放置金属烤瓷冠作为最终修复体之前进行正畸挤压。
