Because movable dentures have little damage to the abutment, fixed dentures need to remove the supporting abutments from a large amount of dental tissue. In contrast, movable dentures only need to wear away a way that can support the socket or pass through the gap of the snap ring. Can be easily repaired. In addition, we can choose the quality and shape of the denture arbitrarily. We can choose different dentures according to our own economic conditions to achieve a satisfactory aesthetic effect.
Fixed dentures connect the prepared abutments or implants on both sides of the missing tooth to restore the anatomy and physiological functions of the chewing organ. However, this type of prosthesis cannot be taken and worn by the patient, and multiple teeth are connected together, and none of the teeth are beautiful in appearance. In addition, it is easy to have dead ends in cleaning. The last point is to increase the burden on the adjacent teeth.
