Study Notes
Maxillary Anesthesia Techniques
- Supraperiosteal Injection Technique
- AKA: Field Block
- Anesthetizes: Terminal branches of the dental plexus
- Effective areas: Pulp of the tooth, root, periodontal ligament, alveolar bone surrounding tooth, buccal soft tissues opposite the tooth
- Indications: Pulpal anesthesia for one or two teeth, soft tissue anesthesia in a small area
- Contraindications: Infection/inflammation in the injection area, dense bone covering tooth apices
- Advantages: High success rate, easy technique, usually atraumatic
- Disadvantages: Not recommended for large areas, may have to use multiple injections with a larger volume of anesthetic
- Positive aspiration probability: Negligible but possible
Basic Maxillary Injection Techniques
- Supraperiosteal infiltration (Field Block): Suitable for one or two adjacent roots
- Posterior Superior Alveolar (PSA) Nerve Block: Suitable for multiple molars in one quadrant
- Middle Superior Alveolar (MSA) Nerve Block: Suitable for premolars in one quadrant
- Anterior Superior Alveolar (ASA) Nerve Block: Suitable for anterior teeth in one quadrant
- Maxillary (V2) Nerve Block: Suitable for all teeth in one quadrant
- Greater (Anterior) Palatine Nerve Block: Suitable for palatal soft tissue distal to the canine
- Nasopalatine Nerve Block: Suitable for palatal soft tissues from canine to canine
- Anterior Middle Superior Alveolar (AMSA) Nerve Block: Suitable for buccal and palatal soft and hard tissues and pulps of anterior teeth
- Palatal Approach ASA (P-ASA) Nerve Block
