                 When all teeth are missing in one arch, the
           patient may choose to have them replaced with
           multiple dental implants. There are multiple ways
           to restore teeth over dental implants. Deciding
           factors include the amount of available bone for
           implantation and costs associated with restoring
           the actual teeth. If enough bone is available,
           porcelain or porcelain fused to metal crowns over
           the implant abutment will provide the most natu-
           ral looking results.

                 A less costly alternative might be plastic
           teeth fused to a metal framework, which is then
           secured to the implants below (figure 39). Either
           way, these restorations are permanent and not
           removable by the patient.

                  If only a limited amount of bone is available
           after the loss of all the teeth in once arch, only
           two or four implants are placed. Upon these
           implants, a metallic bar can be fastened. Then a
           full set of teeth will be fabricated that can “clip” or
           “snap” onto the bar, thereby holding the teeth in
           place. (figure 39). This is called a fitted removable
           prosthesis or an overdenture.

                   There are times when not enough bone
           available. Other times, medical conditions, or
           financial considerations may preclude tooth
           replacement with dental implants.

                                                                                    31
