What is the recommended position for a zygomatic implant relative to the lateral canthus?

• A. 2cm inferior, 1.5-2cm lateral
• B. 3cm superior, 2-3cm lateral
• C. 1cm inferior, 1cm lateral
• D. 2cm superior, 1cm lateral

Answer: (A)

The recommended position for a zygomatic implant is crucial for achieving successful osseointegration and proper function. Positioning the implant relative to the lateral canthus is based on ensuring appropriate angulation and distance to avoid nearby anatomical structures while providing sufficient support for maxillary prosthetics. The option that suggests a position of 2 cm inferior and 1.5-2 cm lateral to the lateral canthus presents a clinically accepted guideline for zygomatic implant placement. This positioning allows the clinician to achieve adequate bone density in the zygomatic bone while ensuring that the implant is oriented favorably to provide the necessary support for dental restorations in cases of severe maxillary resorption. Properly positioning the implant in this manner minimizes the risk of complications, such as neurovascular injury or improper angulation, which could compromise the prosthetic outcome. This recommendation is relevant in clinical practice as it aligns with anatomical studies and previous literature that have emphasized these particular measurements for optimal zygomatic implant success. While other measurements may exist, they either suggest positions that are not as commonly referenced or might compromise the structural integrity and support needed from the zygoma, making the selected position the most rational choice for clinical application.
