Non-Syndromic Tooth Agenesis: Interdisciplinary Case

This case employed orthodontic space redistribution for missing teeth, integrating digital technologies (intraoral scanning, CAD-CAM) for diagnostic and definitive prosthesis fabrication. Resin-bonded bridge wings utilized polyetherketoneketone (PEKK), while fixed bridges adopted high-translucency zirconia ceramic materials. A 17-year-old patient presented with a 10-year history of tooth loss and malocclusion. Extraoral examination was normal, while intraoral findings included partial anodontia, retained deciduous teeth, and an impacted 45th tooth. Anterior dental diastemas and a right-deviated maxillary midline were noted. Treatment involved extraction of retained deciduous and impacted teeth, orthodontic alignment to optimize anterior space, and restoration of maxillary edentulous areas with PEKK-bonded bridges and mandibular defects with fixed zirconia bridges. Non-syndromic congenital tooth agenesis is prevalent in clinical practice, primarily managed via restorative modalities. PEKK resin-bonded bridges offer favorable biomechanical properties, whereas high-translucency zirconia provides superior optical characteristics suitable for anterior single crowns, bridges, and veneers. Digital workflows ensure precise, efficient data acquisition and prosthesis design. Multidisciplinary management of non-syndromic congenital tooth agenesis achieves optimal outcomes by combining orthodontic alignment, advanced biomaterials (PEKK and zirconia), and digital technology for functional and esthetic rehabilitation.
