MARCUS VACCAREZZA, Natalia et al. Rehabilitation of severely atrophic full arches using hybrid prostheses made with chrome-cobalt laser sintering technology: A case report. Rev. Clin. Periodoncia Implantol. Rehabil. Oral [online]. 2016, vol.9, n.1, pp.13-18. ISSN 0719-0107.ínico10.1016/j.piro.2015.03.007.

Abstract Implant-retained metal-acrylic hybrid prostheses provide a functional and aesthetic solution to rehabilitate severely atrophic complete arches, and are an alternative to more complex reconstructive surgeries. the prosthetic substructure must adjust passively on the implants. With the CAD-CAM technology, the manual design of the substructures, by lost wax, has been replaced by digital design. Laser sintering technology in the production of metal substructures has advantages, such as, decreased accumulation of errors, fabrication speed and design of complex geometry, according to the needs of the case. Case report Hybrid prostheses in the maxilla (8 implants) and jaw (Revitalize®) were planned in a patient with no teeth, using Co-Cr alloy substructures by laser sintering, which have similar long-term results as obtained with noble structures, but with lower cost and high predictability. Conclusions Hybrid prostheses with Co-Cr substructures using laser sintering could improve prognosis by incorporating CAD-CAM in their preparation to obtain fine adjustments.
