PM wk 2 max technique

VI

Ophthalmic division

Season, enters through superior orbital fissure

When I was 1 I needed glasses which was not superior

v2

Maxillary division

Sensory, enters through foremen rotundum

2 year old max will turn into a rotund man w/ 4 men who are rotund

V/2 branches

Cranium, face, pterygopalatine fossa, infraorbital canal

Pterygopalatine fossa branches

Posterior superior alveolar nerve (psi), pharyngeal branch, pterygopalatine nerves, palatine branches (greater and lesser palatine nerves), nasal branches (nasopalatine nerve), orbital branches, zygomatic nerve,

Infraorbital canal

MSA and ASA

Nasopalatine route and supplies

Is it nose or palate, men are so indecisive lets go between

Incisive foramen → floor of nose, anterior nasal septum → incisive foreman

Supplies palatal mucosa from canine to canine

Greater palatine route and supplies

Pterygopalatine canal → palate (via greater palatine foremen)

Faux palate gets greater and turns into normal palate at 1st year of preschool

Palatal soft tissue and bone including 1st premol and some soft palate

PSA supplies

Posterior max alveolus, PDL, buccal ging, pulp tissue of molars 1, 2, 3

PSA its M not S and DL not SA, also your cheek and molar pulps will freeze

28% MB root of 1st molar absent

ASA supplies

Anterior max alveolus, buccal ging, PDL, pulp of central, lateral, canine

ASA its actually M not S and another 3 letter word, btw your cheek and one side of anterior pulp will freeze

Dental plexus

Network of sensory fibers formed by trigeminal branches that supply teeth, gingival, supporting structures

Superior dental plexus

ASAN, MSAN, PSAN

Hematoma

Comm w/ PSA (biggie), IANB, mental/incisive

PSA you could get a hematoma Ian so you have to decide if that will affect your mental state

Supraperiosteal injection general

Also known as local infiltration

Operator position varies

Admin slowly @ 1ml per 60 sec

Hold syringe parallel w/ long axis of tooth, insert height of mucobuccal fold above tooth, advance till tip is just above tooth apex (3-6mm)

Supraperiosteal injection supplies

Pulp of max dentition/mand incisor, buccal soft tissue, periodontium of target (small area)

MSA general

Use 27g short 10 o'clock, .9-1.2ml (1/2-2/3 cart)

Insert @ height of mucobuccal fold directly over max 2nd mol

Rely on crossinervation of PSA and ASA bc 28% don't have MSA

MSA supplies

Pulp of max premois, MB root of 1st mol (use for 28% w/o PSA MB)

ASA general

Use for 2+ adjacent anesthesia

25 or 27g short, 10 o'clock, .9 mL, 3-6 mm depth

Insert @ height of MSF just anterior / mesial to canine fossa, angle toward bone

ASA supplies

Max central, lateral, canine pulp
