Stepwise osteotomy protocol for zygomatic implant placement under navigation in patients with extra-sinus trajectory

Area of Science:

• Oral and Maxillofacial Surgery
• Dental Implantology
• Surgical Navigation

Background:

• Zygomatic implant placement is crucial for severe maxillary atrophy.
• Current osteotomy techniques can be challenging under navigation.
• Minimizing free-hand drilling is desirable for enhanced precision.

Purpose of the Study:

• To describe a novel stepwise osteotomy protocol for zygomatic implant placement.
• To evaluate the feasibility of this technique under navigation.
• To improve control and reduce free-hand drilling during zygomatic osteotomy.

Main Methods:

• A stepwise osteotomy protocol dividing the trajectory into three co-axial components was developed.
• The technique utilizes virtual markers for registration under surgical navigation.
• Shorter drills are used initially, followed by a long drill to complete the osteotomy.

Main Results:

• The stepwise osteotomy protocol was successfully applied in a patient.
• Preliminary results indicate a promising approach for zygomatic implant surgery.
• The technique allows for better control during navigation and minimizes free-hand drilling.

Conclusions:

• The stepwise osteotomy protocol offers a controlled method for zygomatic implant placement.
• Further prospective clinical studies are needed to confirm its effectiveness.
• This technique may enhance precision in extra-sinus zygomatic implant trajectories.
