A Digital Workflow for Interdisciplinary Full-Mouth Rehabilitation: Integration of Orthodontics and Prosthodontics

Abstract

A 60-year-old male patient presented seeking replacement of missing posterior teeth and improvement of his smile. Clinical findings included partial edentulism, bilateral posterior crossbite, secondary caries, defective restorations, anterior and posterior tooth wear, posterior gingival inflammation, supraeruption of the mandibular posterior teeth, and unfavorable inclination of the mandibular posterior teeth. An interdisciplinary treatment plan combining orthodontic, implant, and restorative therapy was selected to improve tooth position, occlusion, restorative space, and esthetics before definitive rehabilitation. Following orthodontic treatment, a digital workflow incorporating intraoral scanning, digital wax-up, restorative space evaluation, and computer-aided design was used to plan a full-mouth rehabilitation. Implant-supported restorations replaced the missing posterior teeth, while the remaining dentition was restored with tooth-supported restorations. Partial-coverage restorations and occlusal veneers were used posteriorly to preserve sound tooth structure, and minimally invasive labial veneers were used anteriorly to improve esthetics. Zirconia was selected because of its favorable mechanical properties and clinical versatility. Cementation was performed under complete dental dam isolation to minimize contamination. This case illustrates how a staged interdisciplinary approach supported by digital planning can facilitate conservative full-mouth rehabilitation and maintain satisfactory functional and esthetic outcomes over a 3-year follow-up.
