Dental treatment designed to repair defects in accordance with biological, mechanical and aesthetic criterion three, more comprehensive analysis and when to think, to a coherent and coordinated. What are three considerations?
1. Try to keep dental hard tissue
(1) Preparation of the relative axial tooth Kazakh, cut to about 6 ° C for the polymerization, such as the fire would tilt too much worn out tooth structure. And affect the retention
(2) In addition to the surface of the ground surface in accordance with anatomical shape, the average mill recovery data required in addition to the appropriate thickness.
2. Preparation of o near the tissue surface maintenance available when housing (housing with silicon carbide films) to maintain close to the organization. Maintenance of vital teeth pulp tissue preparation for when water temperature, modulus, after doing a temporary crown.
3. Prosthesis position the edge and the edge of the shape usually have two: one for the non-angular shoulder, the other for the angular shoulder. Two kinds of shoulder edge of the prosthesis has sufficient thickness, the edge position to understand, easy to manufacture, the former is Scaling the different teeth whitening porcelain commonly used in metal casting and PFM crowns the lingual metal edges, and are commonly used in the anterior PFM the edge of the lip surface.
