Peri-implant transmucosal tissue, an essential element of peri-implant esthetics, is critical to the success of prostheses in the esthetic zone. The optimal transmucosal tissue profile can be transferred to the master cast with the aid of custom impression posts. In this clinical technique, the initial cast used to fabricate provisional prostheses was conveniently used to aid in the time-efficient fabrication of multiple custom impression posts simultaneously using self-cured acrylic resin. This technique also applies to single restorations. In addition, the use of an initial cast as holder makes it easy to transfer custom impression posts to the mouth accurately and efficiently.
种植体周围黏膜组织是种植体美学的一个重要组成部分，对于美学区修复体的成功至关重要。借助定制印模桩，可以将最佳的黏膜组织形态转移到工作模型上。在这项临床技术中，最初用于制作临时修复体的工作模型被方便地用于同时使用自凝丙烯酸树脂来高效制作多个定制印模桩。这项技术也适用于单颗牙修复。此外，使用初始模型作为印模桩的固位体，便于准确、高效地将定制印模桩转移到口腔中。
