In addition to dental implants, missing teeth can also be restored through fixed and removable dentures. According to the patient’s condition, requirements and economic status and other factors, choose the appropriate treatment program. 1. Dental implant: In the location of missing teeth, dental implants are surgically inserted into the alveolar bone to achieve the purpose of restoring missing teeth. The advantages are that there is no obvious foreign body sensation, high degree of simulation, and can better restore the chewing efficiency, which is the preferred restoration method for patients with missing teeth. 2. Fixed denture: It is a denture fixed on the healthy teeth on both sides of the missing teeth gap, which can not be taken off and worn freely. Generally can be used for a long time, the advantages are high chewing efficiency, comfort, aesthetics and so on. The disadvantage is the need to wear both sides of the teeth. 3. Activity denture: that is, the surface means that you can remove the denture, the use of remaining natural teeth and the remaining alveolar ridge for support. The advantages are lower cost and relatively less teeth grinding. However, it is not beautiful enough, low comfort, and poor chewing efficiency. It is recommended that patients can choose the appropriate treatment plan according to their own requirements, financial status, condition and other factors.
