The use of modern CAD/CAM technology has revolutionized the manufacturing of veneers by enabling more precise, efficient and personalized treatment. This advanced manufacturing process includes several key steps, from the initial examination to the final placement of the veneers.
1.4.1 Initial examination and treatment planning
Clinical examination: The process begins with a comprehensive examination of the teeth and mouth to evaluate suitability for veneers, taking into account the patient's aesthetic and functional goals.
Defining the treatment goal: Together with the patient, the dentist defines the desired results of the veneer treatment, including improving the color, shape and alignment of the teeth.
Discussion of veneer options: The dentist informs the patient about the different types of veneers, their advantages and disadvantages, and the expected course of treatment.
1.4.2 Digital dental impression
Digital scanning: Instead of using traditional impression materials, a digital scanning device is used to create precise 3D images of the teeth and mouth. This step is quick, comfortable and provides highly accurate data for veneer production.
Creating a 3D model: The digital data is used to create a detailed 3D model of the teeth, which serves as the basis for the design of the veneers.
1.4.3 Design of the veneers
CAD software: Using special CAD software, the dentist or dental technician designs the veneers individually according to the anatomical conditions and aesthetic wishes of the patient.
Adjustment of shape, size and color: The design of the veneers is carefully adjusted to ensure optimal aesthetics and function, paying particular attention to harmony with the surrounding teeth.
1.4.4 Selection of material
Material selection: Depending on the aesthetic requirements and the preferred durability, the dentist selects the appropriate material for the veneers, distinguishing between different types of glass and composite.
1.4.5 CAM manufacturing process
Transfer to CAM unit: The digitally designed veneers are sent to a CAM unit, which precisely mills or 3D prints the design into the selected material.
Computer-controlled milling or 3D printing: Using advanced milling or 3D printing technology, the physical veneers are created and manufactured exactly according to the specified design parameters.
1.4.6 Post-processing and quality control
Hand polishing and adjustment: After production, the veneers are reworked by hand to ensure a smooth surface and precise edges and, if necessary, finalized in the ceramic oven.
Color and translucency adjustment: If necessary, the veneers are color-adjusted to achieve a natural aesthetic.
Quality control: The finished veneers are carefully checked to ensure that they meet high quality standards and fit the patient's teeth perfectly.
1.4.7 Adjustment and attachment to the patient
Fitting: The veneers are fitted in the patient's mouth to check the fit and appearance.
Attaching the veneers: After the final adjustment, the veneers are attached to the prepared teeth with a special dental cement and hardened using a light source.
Final inspection: Finally, a thorough inspection of the fit, bite and aesthetic result is performed to ensure that the veneers meet expectations and are comfortable.
The use of CAD/CAM technology in the production of veneers represents a significant advance in aesthetic dentistry. It enables a customized solution with high precision, leading to improved aesthetic results and increased patient satisfaction.
