1. Teeth grinding

In order to ensure that the thickness of the completed porcelain crown does not exceed the original thickness of the outer teeth after being inserted, it is generally necessary to grind part of the natural teeth to make porcelain teeth. In addition, in order to make the dentures sit smoothly and achieve good retention, the abutment teeth must be prepared into a certain shape. The quality of the abutment preparation is related to whether the dentures are easy to put in and how strong they are.

2. Taking the impression

Before sending it to the factory, the doctor must make a record of the condition of the prepared teeth to provide a basis for the production of porcelain teeth. In two steps, first take a rough impression: use silicone bold to make a rough impression, and trim the undercut portion to create the overflow channel. Then take a fine impression.

3. Color comparison

In order to ensure that the color of the porcelain teeth is similar to that of the original teeth or adjacent teeth, the doctor must quickly browse the color guide and compare it with the original tooth color of the affected tooth. Compare and determine the approximate hue range on the color guide.

Requirements: Under natural light, select a color in the upper 1/3 area of ??the crown of the natural tooth, and use this area color as the main body color, and then compare the neck and incisal color with the main color. Determine the color of these two areas.

4. Trial bonding

The porcelain teeth will be completed in about 1 week. First, after a trial fit, check the tightness of the shoulder, that is, the fit of the crown edge must meet the standards, whether the color is consistent, whether the shape is beautiful, as well as the adjacency relationship, occlusion relationship, etc. If it is confirmed that there are no problems, the doctor will use a special adhesive to bond it to the pre-repaired tooth, and the repair work of the porcelain tooth will be completed.
