This document discusses various techniques for maxillary anesthesia when performing dental procedures:
1. It describes different injection techniques for the maxilla including supraperiosteal, periodontal ligament, intrasseptal, and nerve blocks of the posterior superior alveolar, middle superior alveolar, anterior superior alveolar, maxillary, greater palatine, and nasopalatine nerves.
2. The posterior superior alveolar nerve block technique is outlined which anesthetizes the posterior superior alveolar nerve to numb the maxillary molars and buccal tissue.
3. Advantages, indications, contraindications, and potential complications are provided for the different maxillary anesthesia techniques
9. Areas Anesthetized
Entire area innervated by the large terminal
nerve branches:
Tooth pulp and root area
Buccal periosteum
Mucous membrane and connective tissue
10. Disadvantages
Not suitable for large areas
Multiple needle insertions
Large volumes of anethetic solution
13. Technique
Apply topical
Landmarks - mucobuccal fold
long axis of tooth
Insert needle at height of mucobuccal fold
Target area - apex of tooth
Aspirate, deposit approx. 0.6-1 ml solution
31. Technique
25 gauge, long needle
Position patient and identify landmarks
Advance needle upward, inward and
backward
Aspirate, inject 1.8 ml of solution

34. Failures of Anesthesia
Needle too lateral
Needle not deep enough
Needle too far superior
