Abordagem digital para redução da tuberosidade maxilar com reabilitação protética imediata

Abstract

Digital planning with printed surgical guides is widely used in the installation of dental implants, offering greater predictability and accuracy. This technique, when applied in pre-surgical prosthetic planning in cases of bone changes, optimizes the function and aesthetics of the future prosthesis, ensuring more predictable results. Therefore, this work aims to describe a digital approach to the planning and making of printed guides for bilateral tuberoplasty, followed by the manufacture of an immediate removable partial prosthesis (PPR) printed three-dimensionally (3D). The steps performed were: (1) extraoral scanning of the lip in maximum smile and the models of the partially edentular maxilla and mandible with the respective intermaxillary record in the appropriate DVO; (2) alignment of the virtual models with the scan of the lip and tomography; (3) simulation of the tuberoplasty in Exocad (occlusal plate module) in the axial and coronal planes and design of surgical guides for bone reduction in height and on the vestibular face of the maxillary tuberosities; (4) preparation of the immediate PPR on the virtually operated model using the Exocad total prosthesis module; (5) three-dimensional printing of the surgical guides and the PPR Immediate. The technique described results in the reduction of laboratory and clinical time, enabling a more precise and assertive surgery, in which the patient can be rehabilitated immediately after surgery with the provisional PPR, restoring aesthetics, function and increasing the quality of life.
