industry report _ minimal invasive treatment I the future would be possible without having to make functional or aesthetic compromises. _Planning the correct way As usual, we documented the preoperative situ- ation with photographs. In addition, we determined the where and how of the restorative procedure on thebasisofworkingmodels.Ouraimwastoproduce an appearance that would meet the requirements of thepatient.Adiagnosticwax-upwasproducedanda silicone matrix was created in the dental laboratory, takingintoaccounttheclinicalrequirementsandthe technicallimitations(Fig.4).Incasessuchasthisone, the materials that are selected for the treatment are an important component of the treatment plan.

Therefore, a com- positeresinwasappliedtoteeth#14and24.Thesize of the two deciduous teeth was increased and the appearance of the existing canines was transformed with the composite resin to look like lateral incisors (Fig. 6). Even though the proportions of the central incisors were not yet in harmony with the overall appearance, the patient was satisfied with the aes- theticsofthetry-inofthisminimallyinvasivesolution. _Implementation The final restorative procedure involved ten teeth. With the mock-up as a reference, the shape, size and minimal thickness of the restorations were established. Measures were taken to ensure the predictabilityofthequalityandcontrolofthetech- nical and clinical aspects of the procedure (Figs. 7 & 8). On the basis of the wax-ups fabricated on the working models, six very thin veneers (facial) were planned for teeth #14, 24, 53, 63, 11 and 21. The veneers were so thin that the teeth did not require Fig. 4_A diagnostic wax-up and a silicone matrix were fabricated. Fig. 5_The silicone matrix was used to produce a mock-up of the restoration.
