Area of Science:

  • Oral and Maxillofacial Surgery
  • Dental Implantology
  • Computer-Aided Surgery

Background:

  • Zygomatic implant surgery presents challenges due to limited visibility and complex anatomy.
  • These difficulties can increase the risk of serious surgical complications.

Purpose of the Study:

  • To evaluate the precision of zygomatic implant placement using computer-guided surgical templates.
  • To assess the accuracy of implant positioning in relation to anatomical structures and planes.

Main Methods:

  • 13 zygomatic implants were placed in four participants using computer-guided surgical templates and double-sleeve drill guides.
  • Accuracy was measured by linear (platform, apex) and angular deviations.
  • Implant deviations from sagittal, horizontal, and coronal planes were analyzed.

Main Results:

  • Mean linear deviation at platforms was 2.44 mm ± 1.57; at apices, 2.32 mm ± 1.
  • Mean angular deviation was 3.6° ± 1.92.
  • No statistically significant differences were found in implant deviations across the three spatial planes.

Conclusions:

  • Computer-guided templates and double-sleeve drill guides provide favorable control during zygomatic implant osteotomy.
  • This method aids in avoiding vital structures and achieving optimal prosthetic positioning.
  • The protocol warrants further research for predictable surgical outcomes and complication prevention.
