The philosophy of a gradual transition to an implant retained prosthesis in cases of full-mouth or extensive rehabilitation usually involves a staged treatment concept. In this therapeutic approach, the placement of implants may sometimes be divided into phases. During a subsequent surgical phase of treatment, the pre-existing implants can serve as anchors for the surgical template. Those modified surgical templates help in the precise transferring of restorative information into the surgical field and guide the optimal three-dimensional implant positioning.
This article highlights the rationale of implant-retained surgical templates and illustrates them through the presentation of two clinical cases. The templates are duplicates of the provisional restorations and are secured to the existing implants through the utilization of implant mounts.
This template design in such staged procedures provided stability in the surgical field and enhanced the accuracy in implant positioning based upon the planned restoration, thus ensuring predictable treatment outcomes.
Successful rehabilitation lies in the correct sequence of surgical and prosthetic procedures. Whenever a staged approach of implant placement is planned, the clinician can effectively use the initially placed implants as anchors for the surgical template during the second phase of implant surgery.
在全口或广泛修复病例中,逐步过渡到种植体支持的修复体的理念通常涉及分阶段治疗概念。在这种治疗方法中,种植体的植入有时可分为几个阶段。在随后的手术治疗阶段,先前植入的种植体可作为手术导板的锚定物。那些经过修改的手术导板有助于将修复信息精确地传递到手术区域,并指导种植体进行最佳的三维定位。
本文重点介绍种植体支持的手术导板的基本原理,并通过两个临床病例进行说明。这些导板是临时修复体的复制品,并通过使用种植体基台固定到现有的种植体上。
在这种分阶段手术过程中,这种导板设计在手术区域提供了稳定性,并提高了基于计划修复的种植体定位的准确性,从而确保了可预测的治疗效果。
成功的修复取决于手术和修复程序的正确顺序。每当计划采用分阶段植入种植体的方法时,临床医生在种植体手术的第二阶段可以有效地将最初植入的种植体用作手术导板的锚定物。
