What causes the opening and closing of anterior teeth of complete denture?

Complete denture is a complete denture. It is best to try it on first to see if the base is stable. It is used to reset the occlusion relationship and rearrange the teeth. If the incisor inclination is too small, the cusp balance slope is too large to cause the anterior teeth to open and close. The typical clinical manifestation is that the posterior teeth contact the anterior teeth without contact or the posterior teeth contact the anterior teeth incompletely. The adjustment method is to increase the incisor inclination, increase the overlap, raise the lower anterior teeth, and reduce the cusp balance slope. If the overbite is normal, select a tooth with smaller cusps, increase the incisal slope and decrease the cusp balance slope. If the anterior teeth are still not in contact after decreasing the balance slope, decrease the cusp balance slope, increase the incisal slope, and decrease the curvature of the compensation curve.
