When multiple teeth are missing
In many cases, more than one teeth are missing. In these cases the clinician may choose either the construction of classical prosthetic work on teeth or the placing of fixed prosthesis on 2 or more implants. Classical prosthetics could be either an extended metal ceramic bridge or a partial denture. In both cases, on the other hand, there is need to modify the supporting teeth, and these teeth will receive chewing forces greater than those for which they were intended to.
The procedure of placing and restoring multiple implants is by large the same like in the cases of a single implant. It should be borne in mind, however, that the surgical field is larger, so the patient is expected to experience slightly larger discomfort.
