Abstract

The technique described allowed an implant custom tray to be fabricated referencing the location of connected impression copings. The technique uses dental computer-aided design (CAD) software and 3D printing technology. The method controls the thickness of the impression material around the impression copings, improving the impression-making process.

Discussion

Healing abutments and impression copings of varying diameters and heights were connected to laboratory analogs and scanned to construct the library, which was then used to fabricate implant custom trays. When making a preliminary impression with only the intraoral healing abutment connected, it is possible to simulate the connection of the coping to the implant fixture. Therefore, the CAD software can be used to control the area and amount of impression material so that it can evenly cover not

Summary

The technique presented allows an implant custom tray to be manufactured based on the prediction of impression copings already installed. The manufacturing method allows control over the even covering of impression material around the impression copings.

    In view of the design of a 3D-printed custom tray, the workflow in the present study was simplified and time-efficient, taking a skilled operator about 3 to 7 minutes with the dedicated software program. In previous reports,33-35 the preliminary impression needed pouring and the custom open tray design made with the physical diagnostic cast. Moreover, the procedures used in those reports required switching between different sophisticated software programs, additional time, and a longer learning curve.

    A biomimetic plywood design was adopted to improve elastic modulus, plastic deformation, fracturing and buckling. Dental implant abutments were 3D printed using plastic and metal (Kalman, 2018; Kim et al., 2019b). Presotto et al. (2019) compared the standard casting techniques to selective laser melting and found the 3D printed casts to be the most precise fit for fixed partial dentures (FPD).
