Abstract

Soft tissue healing around implants may turn out to be the most decisive factor in the success or failure of the prosthesis. Dimension, configuration, and material of the healing abutments play a pivotal role in achieving optimal soft tissue architecture around implants. Digital imaging with computer-aided designing and computer-aided machining (CAD-CAM) technology, has made it easier to illustrate, design, replicate maxillofacial structures, and generate its supporting elements in a reliable, faster, and more convenient manner. This case report highlights the issue relevant to the implant-supported prosthetic replacement, on a site previously attempted for surgical reconstruction of the missing ear. Presurgical DICOM data were used to obtain custom CAD-CAM polyetheretherketone (PEEK) healing abutments on implants in a patient with an excessive amount of tissue in the missing right ear region. It is probably the first extraoral use of PEEK as a healing abutment in the workflow of implant retained maxillofacial prosthetics. No issue warranting the removal of the PEEK component was observed during the duration of its use.

摘要

种植体周围的软组织愈合可能是假体成败的最关键因素。愈合基台的尺寸、形状和材料在实现种植体周围最佳软组织结构方面起着关键作用。借助计算机辅助设计和计算机辅助加工（CAD-CAM）技术的数字成像，能够更轻松地以可靠、快速且便捷的方式呈现、设计、复制颌面结构并生成其支撑元件。本病例报告重点介绍了在先前尝试进行缺失耳部手术重建的部位进行种植体支持的假体置换相关问题。术前DICOM数据被用于为一名右耳缺失区域组织过多的患者在种植体上获取定制的CAD-CAM聚醚醚酮（PEEK）愈合基台。这可能是PEEK在种植体固位颌面修复流程中首次在口腔外用作愈合基台。在其使用期间未观察到需要移除PEEK组件的问题。
