What are removable dentures?

Dentures are a product that was created to repair missing teeth in the human body. They are artificial false teeth. Dentures can be commonly divided into removable dentures, fixed dentures and the newly invented invisible dentures. Removable dentures are popular among people because of their simple production and relatively low price, and are widely used. So what exactly are removable dentures? Let me introduce it in detail below.

Removable dentures are also called removable dentures. Removable dentures are divided into removable partial dentures and complete dentures. Removable dentures are a method of restoring missing teeth by replacing them with artificial teeth, using a base to repair the missing mucosa and hard tissue, and using natural teeth and bases for retention and support to repair the missing tooth tissue. Patients can take off and put on removable dentures by themselves. Depending on the material, removable dentures are divided into cement-bonded removable dentures and metal-frame removable dentures.

Common problems of removable dentures 1. Pain is the most common problem: including abutment tooth pain and soft tissue pain. Abutment tooth pain is mostly caused by excessive force or lateral external force from the clasp. Soft tissue pain is mostly caused by the base edge being too long or too sharp, small tumors on the base tissue surface, etc. It can also be caused by the presence of bone tips or bone protrusions or bone ridges on the alveolar ridge, which form tissue concave depressions, thin covering mucosa, dentures squeezing the base downward, and sharp ridges being worn. 2 Poor retention and stability, mainly manifested as: ① Bounce, the clasp does not enter the concave area of ​​the abutment tooth; ② Tilting, swinging, and up and down movement. The reason is that the clasp body does not fit the base, the indirect retainer is placed in an improper position, the occlusal support, the clasp forms a fulcrum on the tooth surface, and the clasp has no retention force; ③ The base and tissue are not in close fit, and the edge is not well sealed; ④ The crown of the abutment tooth is small, or conical, resulting in poor retention; ⑤ The artificial tooth is improperly arranged, and it tilts during occlusion; ⑥ The edge of the base is too long, affecting soft tissue activity. 3. Poor chewing function of dentures may be related to poor shape of the occlusal surface of artificial teeth, poor denture occlusion, too low vertical distance, poor conditions of abutment teeth and alveolar ridges. 4. Difficulty in wearing and removing: the clasp is too tight, the base is close to the tooth surface, the base in the concave area is not sufficiently cushioned, and the patient does not master the direction and method of wearing and removing the denture, which can cause difficulty in wearing and removing. 5 Food impaction: Food impaction and retention between the denture and tissue, the original base not fitting tightly against the tissue, the clasp not fitting well against the abutment tooth, and there is a gap between the base and the natural tooth can all cause food impaction.
