Purpose:
The Gow-Gates technique is said to have several advantages over traditional techniques to achieve mandibular nerve anesthesia; however, its routine use is quite limited, mainly due to complications during visual alignment of reference landmarks. The purpose of this study was to verify the validity and accuracy of a new method to reach the injection site.
Material And Methods:
Fifteen magnetic resonance images were captured. Distances from the ideal injection point in the condylar neck (puncture ideal) to the injection points located in the alpha and beta plane intersection (puncture Gow-Gates and puncture modified) were measured and compared.
Results:
Positive and significant (P
Conclusions:
The modified technique proved to be valid and precise and has a determined and an effective injection site.
