Computer-aided design/computer-aided manufacturing (CAD/CAM) creates custom hydroxyapatite grafts for maxillary sinus augmentation. This technique ensures precise fit and successful dental implant integration, improving surgical outcomes.

Area of Science:

  • Biomaterials Science
  • Dental Implantology
  • Surgical Technology

Background:

  • Maxillary sinus augmentation is crucial for dental implant placement.
  • Current methods rely on manual graft shaping, leading to variability.
  • Surgeon experience significantly impacts graft fit and surgical success.

Purpose of the Study:

  • To develop and evaluate a computer-aided design/computer-aided manufacturing (CAD/CAM) technique for custom sinus graft fabrication.
  • To utilize cone-beam computed tomography (CBCT) for precise surgical planning and execution.
  • To improve the accuracy and predictability of maxillary sinus augmentation procedures.

Main Methods:

  • A novel CAD/CAM technique was employed to preoperatively design and fabricate custom hydroxyapatite (HA) block grafts.
Keywords:

Related Experiment Videos

  • Three-dimensional (3D) simulation guided the precise shaping of HA blocks.
  • A customized cutting guide was developed for accurate lateral wall preparation and membrane elevation.

    • Main Results:

    • Five patients received bilateral sinus augmentations using custom-made HA blocks.
    • Dental implants were successfully placed six months post-augmentation.
    • All implants remained functional for two years with no reported complications.

    Conclusions:

    • The presented CAD/CAM technique offers a precise method for fabricating custom block grafts for sinus augmentation.
    • This approach enhances surgical predictability and patient outcomes in dental implantology.
    • Customized HA grafts produced via CAD/CAM technology are a viable option for maxillary sinus augmentation.
