Study Notes
Maxillary Innervation
- Maxillary teeth and surrounding tissues are innervated by branches of the maxillary nerve (V2), the second division of the trigeminal nerve (CN V).
- The maxillary nerve exits the skull through the foramen rotundum and enters the pterygopalatine fossa.
- From there, it gives rise to several branches including the anterior, middle, and posterior superior alveolar nerves, the greater palatine nerve, and the nasopalatine nerve.
- The anterior superior alveolar nerve innervates the maxillary incisors and canine, the labial soft tissues, and the palatal soft tissues.
- The middle superior alveolar nerve innervates the maxillary premolars and mesiobuccal root of the first molar, the buccal soft tissues of the ipsilateral premolars, and the palatal soft tissues.
- The posterior superior alveolar nerve innervates the maxillary molars except the mesiobuccal root of the first molar, the buccal soft tissues of the ipsilateral molars, and the palatal soft tissues.
- The greater palatine nerve innervates the palatal soft tissues of the molars and premolars.
- The nasopalatine nerve innervates the palatal soft tissues of the incisors and canines.
Supraperiosteal Injection Technique
- Supraperiosteal injection is a field block technique, also known as local infiltration (incorrectly).
- It involves delivering local anesthetic to the terminal branches of the dental plexus close to the apex of the tooth.
- This method provides anesthesia for the pulp of the tooth, the root area, the periodontal ligament, the alveolar bone surrounding the tooth, and the buccal soft tissues opposite the tooth.
- It is an effective technique for treatment involving one or two teeth.
- The technique is contraindicated in cases of infection or inflammation at the injection site, or in cases with dense bone covering the tooth apex.
- Supraperiosteal injection is generally advantageous due to its high success rate (>95%), ease of execution, and minimal trauma.
- However, for larger areas, the need for multiple injections and increased local anesthetic volume are drawbacks.
- The risk of intravascular injection is possible but considered negligible with this technique.
