Active gum care the principle of the row of teeth

(1). Beautiful principle:

Restore the 1/3 of the patients under the surface morphology, reaching 1/3 of the surface under the coordination of the entire facial proportions, people look younger, gives a sense of beauty. Dentition radians to be consistent with the jaw arch type, with a radius of type tip round, oval, the location of the anterior teeth to bring out the upper lip fullness and to achieve the following: the row of teeth to reflect the personality of the patients, according to the face , age, color, selected teeth.

(2). Organizational health functions:

1. The arrangement of artificial teeth either hinders the activities of the tongue, lip and cheek muscles in the muscular equilibrium position.

2. Occlusal plane and the nose tragus line parallel to its height at the outer edge of the tongue side of the most prominent, easy to tongue the food to the occlusal surface of posterior teeth, which will help stabilize the denture in the functional state. Posterior teeth dental instruments function should try to be on top of the alveolar ridge, so that the occlusal force transmitted along the vertical direction to the alveolar ridge.

3. Alveolar ridge absorb more inclined posterior teeth inclination in the direction of adjustment according to the alveolar ridge slope, so that the occlusal force transmitted to the alveolar ridge as far as possible the vertical direction, if the alveolar ridge is severely resorbed, requires attention to dental work together to be the largest at the minimum on the alveolar ridge at the reduce denture Alice in functional status.

4. Front teeth are arranged in a shallow overbite, light coverage, the middle of the front teeth in the tooth timely contact in protrusive and lateral movement of at least 1mm within the next tooth along the tooth bevel slide freely.

5. Free sliding between the upper and lower teeth, have a balance of occlusal contact.

6. Reduce the destabilizing factor in the functional status should be appropriate to reduce non-functional tip, such as the molar buccal tip and lower molars tongue, reducing grind food, denture swing.
