Injection Penetration Site and Depth of Insertion

this will be on the test so know it duh

Where is the penetration site for ASA?

Height of the mucobuccal fold-between canine and lateral incisor. Slightly mesial to the canine eminence.

Where is the penetration site for MSA?

Height of the mucobuccal fold- above the second premolar apex or between the first and second premolars

Where is the penetration site for PSA?

Height of the mucobuccal fold- distal of the second molar

Where is the penetration site for GP?

Palatal soft tissue slightly anterior to the GP foramen

Where is the penetration site for NP?

Palatal mucosal lateral to the widest anteroposterior dimension of the incisive papilla (middle of the teardrop)

Where is the penetration site for IAL?

Slightly lateral to the pterygomandibular raphe at a height 2-3mm superior the coronoid notch

Where is the penetration site for LB?

External oblique ridge distal to the most posterior molar
