ABSTRACT

Traditional surgical techniques for insertion of osseointegrated implants require the performance of full surgery. Recent years have seen the clinical introduction of surgical techniques that require no incisions or mucoperiosteal detachments, which have been framed within the concept of minimally invasive surgery, and among them, computer-guided surgery, perhaps being the most increasingly common clinical application.

The advantages, as noted, are obvious, but we want to emphasise two aspects: first, complete planning and knowledge of the case in question, much more than when planning cases with implants and negatoscope template; and second, the reduction of common postoperative complications (pain, swelling, bruising…) in conventional techniques, making it the best choice for older patients.

This is a female carrying a complete upper prosthesis for the last 10 years, who comes to see us for a restoration of the upper maxilla with a fix prosthesis. No relevant medical history.

Planning is performed via assembly in the articulator and making a dental scan prosthesis. With it properly articulated, a CAT scan is performed and the image processed via the Impla- metric application from the DICOM radiological data obtained.

Insertion of 10 implants (MG Osseous, Mozo-Grau, Valladolid, Spain) is planned and it is performed via guided surgery, using the surgical splint provided by the software supplier.

After the osseointegration time has passed, the implant-supported prosthesis is inserted and the correct adjustment and articulation of the restoration are checked.
