The aim of this study was to present the different stages of prosthetic treatment planning involved in the design of an esthetic smile and improving masticatory function using CAD/CAM technology.The patient underwent the following tests and procedures: CBCT cone beam computed tomography (CS9300, Carestream, USA), intraoral scans and occlusal detection (CS3600, Carestream, USA), a portrait session (Nikon D610, Tokyo, Japan), a face scan (Bellus 3D FaceApp, iPhone XS, Apple ) and registration of individual TMJ angles and mandibular movements with a Zebris for Ceramill device (Amman Girrbach, Germany). All the data were transferred to a Ceramill Mind software (Amman Girrbach, Germany) where they were integrated. The face scan and photos were superimposed on the CBCT. Scans of the dental arches were combined with the CBCT. On this CBCT basis, position of the condyles in the articular fossae was determined.. A Virtual Artex CR articulator (Amann Girrbach, Germany) was attached to the 3D object. Individual TMJ angles and mandibular movements were then introduced.A virtual patient was created in the Ceramil Mind software. The optimal shape and position of each tooth were designed into the programme The wax-up was printed using a 3D printer and a temporary mock-up and final restoration were made for the patient. In te same time, the aesthetics of the smile was improved and a harmonious central occlusion and articulation were obtained on virtual models and in in the patient's oral cavity.The presented digital planning protocol allows to work out an optimal solution in complicated patient cases from a functional and aesthetic point of view. |
