INJECTION TECHNIQUES
• Commonly used injection techniques

MAXILLARY INJECTION TECHNIQUES
• Supraperiosteal Injection (Local Infiltration)
• 25-gauge short needle
• Syringe parallel with long axis of tooth
• Insert at height of mucobuccal fold
• Advance until at or above apex of tooth
• Aspirate
![Page 10: IDC COURSE BASIC LOCAL DENTAL ANESTHESIA...maxillary molars •High success rate •Atraumatic •Minimizes number of injections and volume of anesthetic solution MAXILLARY INJECTION](https://reader030.fdocuments.in/reader030/viewer/2022041023/5ed5665975bf2c1ab115726a/html5/thumbnails/10.jpg)
• Commonly used injection techniques
• Posterior Superior Alveolar Nerve
Block (PSA)
• Indicated for 2 or more
maxillary molars
• High success rate
• Atraumatic
• Minimizes number of
injections and volume of
anesthetic solution
MAXILLARY INJECTION TECHNIQUES
• Area anesthetized – Maxillary 1st, 2nd,
3rd molars
• Small percentage of maxillary 1st
molar failure – additional local
infiltration

MAXILLARY INJECTION TECHNIQUES
• Posterior Superior Alveolar Nerve
Block (PSA)
• 25-gauge short needle
• Syringe parallel with long axis of
tooth
• Insert at height of mucobuccal
fold above maxillary 2nd molar
• Advance upward, inward and
backward, until 4mm of needle
remains visible
• Aspirate

• Commonly used injection techniques
• Inferior Alveolar Nerve Block
(IAN)
• Most frequently used
injection technique
• Indicated for multiple
mandibular teeth
• High risk of positive
aspiration
• Areas anesthetized – mandibular teeth
to midline
• Not including buccal soft tissues
of molars – additional buccal
nerve block
• Small percentage of failure with
incisors – additional local
infiltration
MANDIBULAR INJECTION TECHNIQUES

MANDIBULAR INJECTION TECHNIQUES
• Inferior Alveolar Nerve Block (IAN)
• 25-gauge long needle
• Area of insertion – mucous
membrane on the medial side of
the mandibular ramus
• Place barrel of syringe in the
corner of the mouth on the
contralateral side
• Advance needle until bony
resistance, withdraw 1mm and
aspirate

• Commonly used injection techniques
• Buccal Nerve Block
• Indicated for buccal soft
tissue anesthesia
• Used in conjunction with IAN
to anesthetize mandibular
molars
• Areas anesthetized – soft tissues
buccal to mandibular molars
MANDIBULAR INJECTION TECHNIQUES

MANDIBULAR INJECTION TECHNIQUES
• Buccal Nerve Block
• 25-gauge long needle
• Area of insertion – mucous
membrane distal and buccal to

mucoperiosteum is contacted,
usually 1-4mm

• Commonly used injection techniques
• Vazirani-Akinosi Closed-Mouth
Mandibular Block (Akinosi)

MANDIBULAR INJECTION TECHNIQUES
• Vazirani-Akinosi Closed-Mouth
Mandibular Block (Akinosi)
• 25-gauge long needle
• Area of insertion – soft tissue at
medial border of ramus adjacent
to maxillary tuberosity at the
height of the mucogingival
junction of maxillary 3rd molar

slightly laterally, parallel with the
maxillary occlusal plane, 25mm
into tissue
