Why Every Millimeter Matters in Dentistry

maxillary posterior teeth and the maxillary sinus or neurovascular bundle

This image highlights the anatomical relationship between the maxillary posterior teeth and the maxillary sinus or neurovascular bundle — a critical consideration in surgical and prosthetic dental procedures.

📌 Measured Distances:

M2 (Second Molar): 13.9 ± 1 mm

M1 (First Molar): 13 ± 2.4 mm

P2 (Second Premolar): 13.8 ± 2.1 mm

P1 (First Premolar): 11.8 ± 2.2 mm

C (Canine): 9.9 ± 2.9 mm

🚨 Clinical Relevance:

Implant Placement: Avoid nerve damage & sinus perforation.

Endodontic Treatment: Prevent over-instrumentation and complications.

Surgical Extractions: Helps assess risk of oroantral communication.

Local Anesthesia: Influences effective infiltration or block.

🎯 As dental professionals, understanding anatomical proximity helps us plan treatments that are safe, precise, and minimally invasive.
