the post-operative sensitivity in the procedure, is from the tissues and bone in the areas of the teeth. At the next surgical visit, the flapping back of the tissues is again accomplished, the implant is seated (9), and the tissues are sutured together (10). The anterior teeth are completely ignored in designing the universal subperiosteal implant. It is designed exactly as is a subperiosteal implant for a totally edentulous mandible with one or two exceptions.

Depending on how many teeth remain present, the universal subperiosteal implant may only contain two posterior posts, one on each side of the arch, or in those situations where only cuspids exist, four posts are designed in the implant framework, the anterior ones, however, being in the area of the bicuspids rather than in their usual cuspid area. (fig. 11)

A time lapse of at least three weeks should take place after the implant had been inserted before an impression is taken. This delay in time is primarily so that the gingival tissues around the remaining teeth have sufficient time to heal. The teeth should be reprepared to form new finishing lines to make sure they go well underneath the sometimes receded gingival tissues, and the elastic impression, and bite registration are taken (12), (12a) . The final restoration in these situations can be a full arch fixed bridge (13) or a removable prosthesis that fits over soldered copings and a continuous connecting Dolder bar (14), with or with-out the various types of attachments such as inter-coronal (I-C) attachments, internal clips, Ceka or Gerber or Lew.
