The influence of 3D-CBCT on diagnosis and therapy for surgical interventions of impacted teeth and oral implants
De invloed van 3D-CBCT op diagnose en therapie bij chirurgische verwijdering van ingesloten tanden en plaatsing van orale implantaten
Guerrero Acevedo, Maria; S0161049
For many decades two-dimensional radiographs have been considered as the primary diagnostic tool in oral health care, yet the introduction o f three-dimensional imaging has taken a giant leap forward. This techniq ue offers a series of benefits for clinicians and patients at the expens e of an increased dose. In the present thesis, we aimed to provide infor mation on the role of CBCT in the surgical management of patients with i mpacted mandibular third molars and implant treatment of partially denta te patients. For wisdom tooth removal, CBCT was found superior to panora mic radiography in predicting mandibular nerve exposure during third mol ar removal, and allowed a better description of third molar root morphol ogy. Furthermore, CBCT-based preoperative planning of implant placement allowed observers to plan surgical implant placement with higher scores for subjective image quality and improved surgical confidence. Panoramic -based surgical planning demonstrated clinically important discrepancies as compared to the final surgery, while CBCT-based presurgical planning provided a better agreement with the final surgery.
