A computer guided protocol for post-extraction full-arch rehabilitations

In this case report the author illustrates a protocol for post-extraction fullarch rehabilitation produced with the use of computerized virtual treatment planning and guided surgery. In a 74-year old man presenting a failed maxillary attachment-retained removable partial denture, a treatment plan focused on the immediate loading of a post-extraction full-arch prosthesis was developed. Starting from prosthetic analysis a modular scan template for CBCT examination was designed, with a 3D simulation software a protocol for guided implants placement and prosthetic rehabilitation was setup. With the support of this procedure, the author performed the extraction of eight teeth, the placement of eight implants (including extraction sites) with flapless approach, and the immediate load of a provisional screw retained prosthesis. At one year follow-up clinical and radiographic results were stable. In selected cases, this protocol may offer significant advantages, including one-day treatment, reduced post-surgical discomfort and immediate improvement in function and aesthetics.
