Complete denture row of teeth to consider the aesthetic, functional and organizational health care in three aspects, as follows: 1, the principle of aesthetics, complete denture to restore the physiological shape of the lower 1/3 of the patient’s face, to achieve the proportion of the lower 1/3 of the face and the entire face is harmonious. The beauty of full denture is mainly reflected in the arrangement of upper anterior teeth, to achieve the beautiful need to pay attention to the curvature of the teeth and jaw arch form consistent, the position of the upper anterior teeth to set off the fullness of the upper lip, the arrangement of the teeth to reflect the patient’s personality. In the selection of teeth, according to the patient’s face, age, skin color and the size of the jaw arch selection of teeth, as far as possible to mimic the patient’s original arrangement of real teeth; 2, the principle of tissue health care, the arrangement of artificial teeth does not impede the activities of the lips, tongue, buccal muscles in a balanced position of the muscles, the function of the back teeth as far as possible arranged in the alveolar ridge at the top of the front teeth arranged in the shallow overlay (teeth together), shallow coverage, orthodontics, front teeth do not contact when the jaw in the front of the extended jaw and the side of the jaw movement When at least within the range of 1mm, the lower teeth should slide freely along the upper teeth bevel, there is a balanced contact when sliding freely between the upper and lower teeth to reduce the instability of the functional state, and the non-functional tip is appropriately lowered; 3. Principle of mastication function. Effective mastication and satisfactory occlusion are the main functions of the artificial posterior teeth, there should be the widest cusp contact, the cusp-fossa relationship should be stabilized, and as far as possible, anatomical or semi-anatomical teeth should be selected.
