DENTAL ASIA JULY / AUGUST 2019 56 T he newly released DentalCAD 2.3 Matera from exocad is now available worldwide: with extended features and the new add-on module Smile Creator. With this new release, the company introduces next generation aesthetic planning for users of its leading dental CAD software, offering real in-CAD smile design. Smile creator enables easy-to-use, time-saving and predictable virtual planning of highly aesthetic restorations by combining patient photos, outlines and 3D situations. Read on asMr. Tillmann Steinbrecher, CEOof exocad, andDr.PaulSchnitzspan,SoftwareDevelopmentManageratexocad, explain how Smile Creator solves problems for its users. Next generation smile design According to Mr. Steinbrecher, conventional smile design software solutions rely exclusively on 2D as the basis for virtual planning of aesthetically challenging restorations. However, it is difficult to convert a pure 2D smile design into a three-dimensional prosthesis - with the result that the original planning often cannot be realised at all or only with increased effort. With exocad‘s combined 2D and 3D solution in Smile Creator this problem is solved. SmileCreator starts within the CAD software as an intuitive wizard workflowwhere the user is guided step by step through the design. Once the 2D patient image and scan data have been imported into the CAD software, the first step is to align the two-dimensional patient photo with the 3D models. To do this, the user simply marks two points on the 2D and 3D images and the software matches them (Fig. 1). Simplified workflow Consequently, the familiar procedure follows: models are aligned, the lip line is defined and a facial analysis is performed. The USP of SmileCreator is shown in theplacement of the teeth: simple2D tools Smile Design in 2D and 3D: Making Aesthetics Predictable can be used to edit the tooth shapes in the photo. In the background, the software calculates using real 3D tooth libraries and displays the 3D anatomy in real time for the coming prosthetics (in this case crowns). Parallel to 2D planning, the 3D anatomy can be evaluated and a decisionmade on whether the planned aesthetic can be implemented. The planning result is also a three-dimensional tooth arrangement (Fig. 2). Mr. Steinbrecher further explained, that users first select a template for anterior tooth aesthetics from exocad’s extensive library of tooth shapes, which is then displayed on the patient photo as contour lines, and can be individualised with simple 2D editing tools. In the background, however, exocad’s software uses real 3D tooth libraries and displays the adapted shapes from different angles in real time - in the context of the patient’s jaw scan. Additionally, Dr. Schnitzspan stated that parallel to 2D planning users can also assess the 3D situation. Users can now easily determine whether the planned aesthetics are actually feasible. The result is a complete three-dimensional tooth arrangement. Thanks to additional exocad modules, this can then serve as the basis for a printed mock-up model or the final restoration. The case does not have to be replicated in 3D in the laboratory. This is possible because Smile Creator is directly integrated into the exocad DentalCAD software calling it the In-CAD Smile Design. In the final step, the user selects the appropriate tooth shade to create a natural and aesthetic image of the patient. Various standard shades are available for this purpose; in addition, the user has the option of directly copying the patient’s tooth shade from the original image using a picker tool. The visualised final result can be sent as a Jpeg image to the dentist (Fig. 3). Fig. 1 Fig. 2
