UNIVERSIDAD CATÓLICA SAN ANTONIO DE MURCIA (UCAM) INTRODUCCIÓN Y OBJETIVOS The most recent publications have proposed zirconia as a valid material for full arch implant-fixed prosthesis. Many research papers have provided great results for zirconia in terms of physical, mechanical, biological and aesthetic properties. However, it is important to know the limitations and drawbacks this material presents. The most challenging limitation about zirconia is its high modulus of elasticity, making it a really stiff material: it is a great material for working under compression stress but not under tension, compromising its longevity on determined types of prosthetic designs and opposing dentitions.To overcome these problems, a relatively new approach has been proposed for reconstructing atrophic patient’s maxilla’s and mandibles using a titanium-zirconia structure (with or without porcelain): a titanium bar as a primary structure and a zirconia framework as secondary structure. The main aim of this clinical poster is presenting a clinical case about a totally edentulous maxillary and partially edentulous mandibular severely atrophied patient who has been rehabilitated with a titanium-zirconia implant- fixed full arch prosthesis in the maxillary arch. METODOLOGÍA A 48 year old female patient with no medical antecedents presented with a maxillary complete denture and mandibular removable partial denture looking for a fixed solution both for the maxillary and mandibular edentulous areas. Presented extreme vertical and horizontal atrophy in the whole maxilla and severe atrophy in sextants four and six in the mandible.The patient was restored with a titanium-zirconia implant-fixed full arch prosthesis in the maxillary arch and two partial zirconia implant-fixed prosthesis in the mandible. RESULTADOS The placement of a titanium-zirconia implant-fixed full arch prosthesis in the maxillary arch worked in a satisfactory way for the patient and presents numerous advantages when compared with conventional full-contour zirconia full arch prosthesis:- Higher clinical predictability- Permits some degree of technical imprecisions (passivity)- Higher lab predictability- Best option for cantilevered zirconia restorations- Ease of maintenance. CONCLUSIONES Based on this case, it can be affirmed that atrophic patients who need implant-fixed full arch prosthesis can be approached in a predictable way using a titanium bar as a substructure for a zirconia supra-structure. However, further long-term data studies are needed in order to evaluate success and complications over the time. Pósteres Clínicos – PC SALA DE PÓSTERES
