Common Problems With Active Dentures

1. Pain is the most common problem: including base tooth pain and soft tissue pain, base tooth pain is mostly due to excessive force or ring side outward force. Soft tissue pain is caused by the baseto edge is too long, too sharp, the baseto tissue surface has small tumor, etc. , but also because the tooth groove part has bone tip or bone protrusion, bone crucible, forming tissue indentation, covering the mucous membrane thin, the denture squeeze baseto sinking, sharp grinding and so on caused.

2. Poor fixation and stability, mainly manifested as:

(1) bouncing, the card ring did not enter the indented area of the base teeth;

(2) the swing, swing, up and down, because the card ring body and the base to do not fit, indirect solid position placement is not appropriate, tooth-in-place, card ring in the tooth surface to form a fulcrum, the card ring does not hold the position force;

(3) the baseto and the organization is not tight, the edge is not closed ;

(4) the base tooth crown is small, or cone-shaped solidity difference,

(5) the position of artificial tooth arrangement is not correct, when the bite occurs warping,

(6) the edge of the baseto is too long, affecting soft tissue activities.

3. Poor function of tooth chewing, may be related to the bad shape of artificial tooth gnashing surface, bad denture bite, low vertical distance, poor base teeth, tooth groove conditions

4. Removal difficulties: the card ring is too tight, Kitto close to the tooth surface, indented area kitto buffer is not enough, the patient did not master the direction and method of denture removal, can cause removal difficulties.

5. Food plug: between the dentures and tissues between the inlay and stranded food, the original base and tissue is not close, the ring and the base teeth do not fit, kitto and natural teeth between the gap, can cause food plug.
