A single prosthesis (crown) is used to replace one missing tooth – each prosthetic tooth attaches to its own implant. A partial prosthesis (fixed bridge) can replace two or more teeth and may require only two or three implants. A complete dental prosthesis (fixed bridge) replaces all the teeth in your upper or lower jaw. The number of implants varies depending upon a variety of factors. A removable prosthesis (over denture) attaches to a bar or ball-in-socket attachments, whereas a fixed prosthesis is permanent and removable only by the dentist.nnDrs. Fettig, Naumann, Pruner and Zemplenyi perform in-office implant surgery in a hospital-style operating suite. Inpatient hospital implant surgery is for patients who have special medical or anesthetic needs, or for those who need extensive bone grafting.
