Intaglio surface dentistry7/21/2023 It is essential to understand whether a lab-fabricated crown has been sent to the office pre-etched. When a commercial laboratory fabricates the restoration, the lab (if instructed) will send it to the office pre-etched (figures 3 and 4). It is essential that the etching-silanating process occurs after the restoration has been tried in for the fit to be verified intraorally and before the bonding process.įigures 1 and 2: Hydrofluoric acid and silane in separate steps Monobond Plus (Ivoclar Vivadent), a silanating agent Lab-fabricated all-ceramic restorations Although Ivoclar Vivadent manufactures this silanating agent, most companies that make bonding resins have a silanating agent as part of their bonding kits. One such silanating agent is Monobond Plus (Ivoclar Vivadent) (figure 2). Many dentists who mill restorations in their offices conventionally etch the restorations with a hydrofluoric acid etchant and then apply a silane coupling agent prior to bonding (figure 1). Although many of us focus on proper diagnosis, treatment planning, and restorative design, proper conditioning of the bonding surface is a crucial part of the adhesive luting process. The long-term success of these restorations is dependent on multiple factors, including preparation design, the type of ceramic for the clinical scenario, occlusion, and how the surface of the ceramic is treated prior to bonding.

In this article, Maryanne Salcetti, DDS, explains how you should be pretreating restorations you've milled in your office and lab-fabricated restorations, and she identifies a solution for simplifying the etching and silanating process. This article presents computer-guided implant planning, using a patient's existing RPDP.Pretreating all-ceramic restorations is critical to their long-term success. However, although a misplaced implant under an RPDP can cause various complications, as yet, no technique has connected the information on a patient's existing RPDP to the implant planning software. This procedure can be done by connecting the data from the intaglio surface of the RPDP to the residual ridge data of the cone beam computed tomography scan with implant planning software. ![]() This article presents computer-guided implant planning, using a patient's existing RPDP.ĪB - Converting a conventional removable partial dental prosthesis (RPDP) into an implant-assisted removable partial dental prosthesis (IARPDP) may be facilitated by using data from the intaglio surface of the RPDP for proper implant placement.
