The big teeth are lost and need veneers which can be repaired by implant denture, fixed denture or removable denture, as follows. 1. Implant Denture: It is a method to implant the implant into the jawbone to provide support, and use the abutment and the restoration on it to restore the shape and function of the teeth. Fixed implant denture or semi-maxillary overdenture can be chosen. It should be noted that implant denture requires more jawbone than other restorative methods. 2. Fixed Denture: Fixed denture needs to grind down the teeth on both sides of the prepared big teeth as abutment teeth, and then make crowns, which is damaging to the neighboring teeth. 3. Removable Denture: Using natural teeth, mucous membrane and jawbone as support, artificial teeth are used to restore the form and function of teeth. Patients can remove and wear it by themselves, which is easy to scrub and repair, but due to its large size and many parts, patients have obvious sense of foreign body. In addition, its stability is not as good as implant denture. For the same disease, patients have different conditions and choose different treatments, so it is recommended to visit the hospital.
