Chief complaint

Unstable removable prosthesis that prevented the patient from eating or speaking well. Main request to improve esthetics of the restoration.

Oral examination

The clinical evaluation and radiological exams (OPG and CBCT) revealed moderate resorption in the maxilla and a severely reduced vertical dimension in the posterior region.

Treatment

Fixed immediate rehabilitation using four Straumann® BLX (posterior tilted) implants, due to limited posterior bone availability and further placement of the monolithic zirconia restoration.

Clinical and radiographic examination

The radiological exams (OPG) revealed moderate resorption in the mandible, narrow edentulous ridges and limited vertical bone availability in the posterior areas.

Digital impression

Fixed scans have been performed for the Straumann® RevEXTM workflow: four intraoral: opposing arch, soft tissue with screw-retained abutments in place, screwed temporary denture in place, bite registration and one extraoral scan of the temporary restoration with Straumann® RevEXTM  scanbodies in place.

Final restoration

“The Straumann® RevEXTM scan bodies provides an alternative method to efficiently and precisely capture complete arch implant positions. Better yet, this extraoral technique overcomes the challenges of intraoral scanning making it a practical way for clinicians to stay in a digital workflow. “
