The use of prefabricated titanium tissue abutments for the construction of a maxillary subperiosteal implant.

This article presents a bimodal procedure for a patient with an implant-supported fixed partial denture (FP2 class of Misch) where endosteal implants (EOIs) and a subperiosteal implant (SPI) were indicated in different sections of the same arch. In edentulous patients, heterogeneous bone volume and density may be encountered in different regions of the same arch. When the available bone is favorable, the use of EOIs is simpler and less time consuming.
