Inhouse workflow for single-stage, indirect restorations.
The digital inhouse workflow consists of the components optical impression, computer-aided design (CAD) and machine manufacturing. In the sense of a time-optimized workflow, coordinated, closed systems prove to be the better solution. The company 3Shape (Copenhagen, Denmark) started with the existing Trios Intraoral Scanner and added both the software component Trios Design Studio and a number of 'trusted connection mills.' In combination with a collection of 'trusted materials,' a fast workflow with high clinical safety can ultimately be guaranteed. In order for a single-stage in-house restoration to be successfully completed, it is advisable to carry out thorough diagnostics and pretreatment; prepare the restoration by machine with a clear representation of the margin lines; organise the manufacturing process in a competent manner; and use an adhesive, target-oriented fastening strategy. Individual sections of the workflow can be delegated to specially and comprehensively trained medical staff. The increasing networking of digital processes creates very useful synergy effects such as the visualization of possible therapy results, follow-up, smile design, and the planning of implant restorations. A clinical case of a single-stage, in-house restoration with three posterior crowns is presented.
