Fully digital fixed orthodontic prosthesis: use of PEEK technopolymer in cases of early loss of primary incisors

Abstract

BACKGROUND: The aim of this paper is to illustrate a new, fully digital approach to temporary rehabilitation in the case of premature loss of deciduous incisors, using a metal-free fixed orthodontic prosthesis made of polyether ether ketone (PEEK). CASE REPORT: Clinical report: Technopolymer Orthodontic Prosthesis (TOP) is a complete CAD-CAT (Computer Aided Design-Computed Aided Technofacturing) fixed device that can be used to rehabilitate the mouth of very young patients, both from an aesthetic and functional point of view as well as maintaining space and controlling growth. The appliance is customised, designed to be cemented with adhesive technique, using deciduous teeth as anchorage. Two cases of patients in deciduous dentition with early loss of incisors are illustrated to present this procedure. In the first case the patient lost 2 central incisors and in the second one 3 lower incisors were lost due to trauma. CONCLUSION: TOP, made by metal-free technopolymer and cemented on deciduous teeth, proved to be comfortable, aesthetic, easy to apply and efficient in rehabilitating smile and mastication in case of trauma or premature loss of deciduous incisors.
