Currently, there are two main ways to restore missing teeth in the clinic: movable prosthesis and fixed prosthesis. The movable denture is made of plastic or metal, with a ring and denture attached to the base, which is fixed on the original teeth by the ring, and can be taken off and worn by the patient. The advantages of movable denture are: wide range of application, from missing a tooth to all missing teeth can be used; less abrasion of dental tissues during restoration, the patient can take off and wear on his/her own, easy to scrub and clean to maintain good oral hygiene, easy to make, low cost, if the movable denture base is broken or artificial teeth are added, as well as other problems can be remodeled on the original denture and other advantages. However, compared with fixed denture, the disadvantage of removable partial denture is large size, more parts, the patient will often feel a foreign body sensation when first wearing, sometimes affect the pronunciation, and even cause nausea, its stability and chewing performance are not as good as fixed denture, serious cases will lead to damage to the abutment teeth, mucosal ulcers, plaque and tartar buildup, dental caries and periodontitis, accelerated resorption of the alveolar ridge, TMJ disorders, and other adverse consequences. The volume of denture is similar to the volume of original natural teeth, the edge of the denture is close, the patient feels comfortable without obvious foreign body sensation, it is easy to adapt to, and no need for the patient to take off and wear, it is easy to use; 4, the denture on the tongue of the functional activities of the obstacle is small, it does not affect the pronunciation function of the patient, and it will not cause nausea and other symptoms; 5, the color of the fixed denture is close to the natural teeth, which is in line with the aesthetic standard. However, the adaptive range of fixed denture is narrower than the movable denture, not in any case can choose fixed restoration; fixed bridge after cementation is not easy to repair; fixed restoration of the cut abutment tooth body tissue is relatively more, which is the biggest disadvantage of fixed denture restoration Which kind of denture restoration to choose according to the patient’s oral cavity depends on the specific situation, if the oral cavity and good health, the number of missing teeth is less than three oral cavity If the oral and physical health condition is good, and the number of missing teeth is less than three, you can choose fixed denture repair, and if the number of missing teeth is more, and do not want to grind the teeth, then you can choose the movable denture for repair. Of course, these are subject to the clinician’s examination. Regardless of the movable denture or fixed denture, the best denture is the one that suits you!
