In the described technique, a vinyl polysiloxane material is used as a matrix for the indirect fabrication of multiple custom-cast posts and cores. The matrix technique enables the clinician to fabricate multiple posts and cores in a short period of time. The form, harmony, and common axis of preparation for all cores are well controlled before the definitive crown/fixed partial denture restorations are fabricated. Oral tissues are not exposed to the heat of polymerization or the excess monomer of the resin material when this technique is used.
在所描述的技术中，乙烯基聚硅氧烷材料被用作间接制作多个定制铸造桩核的基质。该基质技术使临床医生能够在短时间内制作多个桩核。在制作最终的冠/固定局部义齿修复体之前，所有桩核的形态、协调性和共同就位道都能得到很好的控制。使用该技术时，口腔组织不会暴露于聚合热或树脂材料的过量单体中。
