In a case by Dr Francisco García Torres, we learn how he restored the teeth of a young patient using Prettau Skin veneers.
Initial situation: young patient suffering from caries, missing restoration of teeth 46 – 47 and different composite fillings.
Planned restoration: minimally invasive preparation of tooth enamel and restoration with Prettau Skin veneers, sandwich technique on tooth 23.
Workflow
- Digital tooth set-up in the Zirkonzahn.Modifier software using the DEMI tooth set from the Heroes Collection virtual library; tooth individualisation
- Design and milling of a digital block-out model for the upper and lower mock-ups in Temp Premium Flexible
- Based on the patient-specific model articulation and the selection of a digital Monsons Sphere with Ø 240 mm, the areas to be prepared in the occlusal region were highlighted and a preparation guide for the upper jaw was created. After determining the centric relationship, it turned out that, due to the new occlusal height, the canine 23 needed a palatal support surface to optimise function. Therefore, a vestibular and a palatal veneer were designed to avoid too invasive preparation of the natural tooth. During cementation, the vestibular veneer was applied first, and then the palatal one (‘sandwich technique’)
- Placement of a retraction cord, minimally invasive preparation of teeth and final intraoral scan with Detection Eye by the dentist
- Production of Prettau Skin veneers in Prettau 3 Dispersive zirconia with a minimum thickness of 0.2 mm
- Sintering and characterisation with the ICE Stains 3D by Enrico Steger
- Adhesive cementation of the final restorations; manufacture of a transparent splint to protect the zirconia restorations
- During follow-up by the practitioner, phonetics and aesthetics were rechecked, confirming the success of the treatment.
