In recent years, dental implant rehabilitation has faced demands from prosthetic and esthetic arenas that call for increasingly ideal outcomes, which require precise surgical planning and placement. Anatomic limitations and bone quantity and quality can now be evaluated using more sophisticated radiographic techniques, although transferring this information to the surgical phase has been at best a difficult task. Recently, computer-aided design and manufacturing have made it possible to use data from computerized tomography to not only plan implant rehabilitation, but also to transfer this information to the surgery. One of these techniques uses stereolithography, a laser-driven polymerization process that fabricates an anatomic model and surgical templates. This novel approach is illustrated with two advanced cases, demonstrating that the technique not only allows for the precise translation of the treatment plan directly to the surgical field, but also offers many significant benefits over traditional procedures.
近年来,牙种植修复面临着来自修复和美学领域的需求,这些需求要求获得越来越理想的效果,而这需要精确的手术规划和植入。尽管将这些信息传递到手术阶段一直是一项艰巨的任务,但现在可以使用更先进的放射成像技术来评估解剖学限制以及骨量和骨质量。最近,计算机辅助设计和制造使得利用计算机断层扫描数据不仅能够规划种植修复,还能将这些信息传递到手术中成为可能。其中一种技术是使用立体光刻法,这是一种由激光驱动的聚合过程,可制造解剖模型和手术模板。本文通过两个先进病例说明了这种新方法,证明该技术不仅能够将治疗计划精确地直接转化到手术区域,而且与传统方法相比还具有许多显著优势。
