Description
technical field [0001] The invention relates to the technical field of protective appliances, in particular to a special protective appliance for oral clinical tooth preparation. Background technique [0002] The so-called tooth preparation is to grind the tooth into the shape needed to repair the defect. Generally, the cavity should be guided into a square shape according to the situation, and the porcelain tooth is generally prepared into a cone-shaped cylinder with a taper of 10%, just like building a house. The principle of knocking, knocking, and dismantling is that the incisal edge of the crown should be inclined to the lingual side, so that the prepared teeth present an inclined plane, so that the prepared teeth will look better, and the braces will be more secure. The angle of inclination can also be chosen by the doctor according to the condition of the teeth. Whichever angle is suitable, the angle can be chosen. The purpose of tooth preparation is to ensure that th...
