Digital approach to complex oligodontia rehabilitation

Year: 2024

Type: article

Abstract: Full mouth rehabilitation poses significant challenges, particularly for young individuals afflicted with oligodontia. The key to simplifying a complex case lies in the unity and coordination of a multidisciplinary team, facilitated by comprehensive digital planning. By employing a combination of 2D Smile Design, 3D Diagnostic Mock-ups, and 4D Functional Mock-ups, each team member gains clarity on their role at every step, enabling constant verification through digital superimposition. A 31-year-old was referred due to masticatory dysfunction, aesthetic concerns, and a pronounced chin. After gathering data through intraoral scans, photographs, and CBCT. Patient had only two central incisors in the upper arch and complete anodontia in the lower arch. Diagnosed with oligodontia based on patient history and radiographic evidence, the team distinguished between true and pseudo skeletal class III malocclusion. Initial steps included digital planning for orthognathic surgery and the use of a mobile prosthesis for determining vertical dimension of occlusion and occlusal assessment. Subsequent stages involved guided implant surgery, preserving the central incisors in the upper jaw, and implementing an "All on 7" strategy in the lower jaw, complemented by orthodontics with aligners and aesthetic enhancements using veneers and removable dentures. Oligodontia results from mutations in specific homeobox genes critical for jaw development, leading to insufficient dental and bone development. A cause-and-effect-based treatment plan, utilizing Revers Planning, is essential for addressing these deficiencies comprehensively. Managing complex cases necessitates a structured approach, following a 2D-3D-4D protocol that clarifies each team member's responsibilities and integrates both medical objectives and patient-specific needs.
