![]() Too much soft tissue silicone and the analog may become unstable in the cast. The Gingitech should cover the prosthetic connection, just apical to the head of the implant analog. Next, syringe the soft tissue silicone (Gingitech, Ivoclar Vivadent). Since the silicone tends to adhere to the PVS impression material, apply a thin layer of silicone separator to the impression (Divorce, Anaxdent USA). In this step, the silicone gingival mask will be added. (Click the link to learn more about using an implant abutment placement jig.) Verify the components are seated and then insert the impression post/analog complex into the impression. Chairside or in the laboratory, connect the impression post with an appropriate analog. Remove the closed-tray impression post and replace the healing abutment. In this example, I am using a closed-tray technique, but an open-tray approach would work just as well. Option 1: The Soft-Tissue Working Cast Step 1 - Impression Nevertheless, it is always beneficial to know more than one way to complete a project. Inevitably, both clinicians and technicians will tend to gravitate toward a preferred method of cast fabrication. In the second article, I will describe the steps required for fabricating a stone working cast. In this article, I will describe the steps involved with fabricating a soft-tissue cast. In this two-part series, I’ll describe two techniques for fabricating an implant working cast. When using an indirect method, it is necessary to fabricate a working cast. Generally speaking, implant provisionals may be fabricated either directly or indirectly. Several techniques for fabricating provisional implant restorations exist. Typically, we think about this approach for anterior implant restorations, yet the significant size discrepancy between the mesial-distal width of the edentulous space and healing abutment caused me take this additional step. In other words, I wanted to create a customized emergence profile. I wanted to create a more optimal connection between the desired supragingival restorative contours and the implant’s prosthetic connection. In the case above, I chose to use a provisional restoration to prosthetically sculpt the peri-implant gingival tissues. Evaluating status of osseointegration, especially with a “questionable” implant.Interim restoration as an aid in sequencing or phasing a case.Rationale for implant provisionalization includes: There are many reasons clinicians may choose to fabricate and utilize a provisional implant restoration.
