Cranioplasty implants are routinely fabricated from commercially pure titanium plates by maxillofacial prosthetists. The differing fabrication protocols adopted by prosthetists working at different hospital sites gives rise to considerable variations in surface topography and composition of cranioplasty implants, with residues from the fabrication processes having been found to become incorporated into the surface of the implant. There is a growing recognition among maxillofacial prosthetists of the need to standardise these protocols to ensure quality and consistency of practice within the profession. In an effort to identify and eliminate the source of the inclusions associated with one such fabrication protocol, the present study examined the surfaces of samples subjected to each of the manufacturing steps involved. Surface and elemental analysis techniques identified the main constituent of the surface inclusions to be silicon from the glass beads used to texture the surface of the implant during fabrication. Subsequent analysis of samples prepared according to a revised protocol resulted in a more homogeneous titanium dioxide surface as evidenced by the reduction in area occupied by surface inclusions (from 8.51% ± 2.60% to 0.93% ± 0.62%). These findings may inform the development of improved protocols for the fabrication of titanium cranioplasty plates.

颅骨成形术植入物通常由颌面修复师使用商用纯钛板制造。在不同医院工作的假肢师采用的不同制造协议导致颅骨成形术植入物的表面形貌和成分发生相当大的变化，已经发现制造过程中的残留物会被结合到植入物的表面。颌面修复师越来越认识到需要标准化这些协议，以确保行业内实践的质量和一致性。为了识别和消除与此类制造协议相关的夹杂物的来源，本研究检查了经过每个制造步骤的样品的表面。表面和元素分析技术确定表面夹杂物的主要成分是来自玻璃珠的硅，该玻璃珠用于在制造过程中对植入物表面进行纹理化。根据修订后的协议制备的样品的后续分析导致更均匀的二氧化钛表面，这可以通过表面夹杂物占据的面积减少（从 8.51% ± 2.60% 到 0.93% ± 0.62%）来证明。这些发现可能会为钛颅骨成形板制造改进方案的开发提供信息。根据修订后的协议制备的样品的后续分析导致更均匀的二氧化钛表面，这可以通过表面夹杂物占据的面积减少（从 8.51% ± 2.60% 到 0.93% ± 0.62%）来证明。这些发现可能会为钛颅骨成形板制造改进方案的开发提供信息。根据修订后的协议制备的样品的后续分析导致更均匀的二氧化钛表面，这可以通过表面夹杂物占据的面积减少（从 8.51% ± 2.60% 到 0.93% ± 0.62%）来证明。这些发现可能会为钛颅骨成形板制造改进方案的开发提供信息。
