Anatomical bases for the insertion of zygomatic implants

Area of Science:

• Oral and Maxillofacial Surgery
• Anatomical Studies
• Dental Implantology

Background:

• Zygomatic implants offer a solution for severe maxillary atrophy.
• Precise anatomical measurements are crucial for successful zygomatic implant placement.
• Understanding zygomatic bone and maxilla anatomy is key to avoiding surgical risks.

Purpose of the Study:

• To determine anatomical parameters for four-implant zygomatic techniques.
• To provide measurements of the maxilla and zygoma for implant installation.
• To establish critical angles and distances for zygomatic implant surgery.

Main Methods:

• Performed linear and angular measurements on 40 dry human skulls.
• Analyzed anatomical landmarks of the maxilla and zygoma.
• Collected data for conventional and four-implant zygomatic techniques.

Main Results:

• Installation angles for the four-implant technique ranged from 25-47 degrees; conventional zygomatic implants ranged from 39-62 degrees.
• Distances from the alveolar crest to the orbital socket lateral margin were measured (53.42 mm canine, 42.47 mm premolar).
• The required length for additional implants exceeded the maximum available length (61.94 mm vs. 52.5 mm).

Conclusions:

• Avoid perforation risks by adhering to specific angle ranges for both implant techniques.
• Careful measurement is essential as additional implant lengths may exceed current market availability.
• These anatomical insights aid in planning safer and more effective zygomatic implant procedures.
