With single-tooth implant restorations, a divergence between implant and crown axes, a lack of interocclusal space, and supracrestal implant placement may result in fabrication problems for the prosthetic crown. It was found that the CeraOne abutment can be modified in three ways: (1) height reduction is possible; (2) a 15-degree taper can be applied; and (3) the cervical shoulder can be reduced in height with a chamfer remaining. For these modified abutments, the Celay-InCeram system was used to create individual, all-ceramic crowns for these modified abutments with improved esthetics.
对于单颗牙种植修复，种植体与牙冠轴线之间的差异、牙合间间隙不足以及种植体龈上位置可能会导致修复牙冠的制作问题。研究发现，CeraOne基台可以通过三种方式进行修改：（1）可以降低高度；（2）可以应用15度锥度；（3）可以降低颈部肩台高度并保留倒角。对于这些修改后的基台，使用Celay-InCeram系统为这些修改后的基台制作个性化的全瓷牙冠，以改善美观效果。
