Topical Anesthetics

– which can be in a gel form, spray and ointment

form.

Application of topical anesthetics allows easier

and painless insertion of he sharp needle.

Local Infiltration

– When small terminal nerve endings are

anaesthetized and become insensitive to pain.

In this case incision is made in the same area

where the solution has been deposited.

Infiltration anesthesia is often used for minor

surgical and dental procedures.

With local infiltration we can anesthetize all

maxillary teeth and mandible incisors.

Nerve Block-Which nerves do we block on Maxilla?!

Infraorbital Nerve (Anterior superior alveolar

nerve, Middle superior alveolar Nerve)

Posterior Superior Alveolar Nerve (Tuberosity

N.Block)

Greater Palatine Nerve

Nasopalatine Nerve

Middle superior alveolar nerve

Posterior superior alveolar nerve

nasopalatine nerve anterior teeth

greater palatine nerve premolars & molars

Anterior superior alveolar

nerve

Premolars (4.5) &part of

first molar (6)

Anterior Teeth (1,2,3)

Molars, except root of first

molar

Nerve supply of maxillary teeth

Infraorbital Nerve Block

– Block of Anterior and Middle Superior Alveolar

Nerves

Infra Orbital Nerve Block

Areas Anesthetized:

Incisors

Canines (Cuspids)

Premolars (Bicuspids)

Part of the first molar (Mesiobuccal root)

Bony support and soft tissue

Upper lip

Lower eyelid

Portion of the nose

How to approach the Infra Orbital Nerve?

Area of insertion : Needle is inserted into the mucosa

and the areolar tissue using the Maxillary Bicuspid

as the guide and the needle should pass beneath

and lateral to the external maxil

Area will be anesthetized in 3-5 mins.

Posterior Superior Alveolar N.Block

anesthetize maxillary molars except the mesio-

buccal root of the first molar, which is supplied by the middle superior alveolar nerve

Posterior Superior Alveolar N.Block

Area of insertion - height of mucobuccal fold height of mucobuccal fold between 1st and 2nd molar

45 degree angle aimed superiorly,medially and

posteriorly = upward,backward,inward

Wait 5 minutes before working. Insert about 15 -

20mm

Incisive Nerve Block

(Nasopalatine nerve block)

Can be used to anesthetize the soft and hard tissue of the maxillary anterior palate

Nasopalatine nerve block

Area of insertion is incisive papilla into incisive

foramen

located in the midline behind the central incisors

Greater Palatine Nerve Block

Can be used to anesthetize the palatal soft tissue of

the teeth posterior to the maxillary

useful when treatment is necessary on the

palatal aspect of the maxillary premolar and

molar teeth

Foramen usually lies distal to the upper 2 molar,

but it can also be a bit anterior.

Greater Palatine Nerve Block

Area of insertion for the greater palatine nerve

block is one centimeter medial to the junction of the maxillary 2 and 3
