17
Q

how can you locate the foramen

A

palpation

18
Q

how far away is the foramen from the vestibule

A

~16mm

19
Q

what is the insertion depth for the ASA nerve block

A

1/2 length of needle

20
Q

where should you orient the needle bevel in the ASA nerve block

A

towards the bone

21
Q

how much should you inject in the ASA nerve block

A

0.9-1.2mL

22
Q

when should you apply pressure to the foramen during the ASA nerve block

A
  • during injection
  • maintain pressure one minute after injection
23
Q

what areas are anesthetized in the ASA nerve block

A
  • maxillary central through canine
  • premolars
  • MB root of first molar in 28% of patients
  • buccal periodontium and bone
  • lower eyelid, side of nose, upper lip
24
Q

what are the indications for the ASA nerve block

A
  • procedures on two or more teeth
  • inflammation or infection
  • dense cortical bone making supraperiosteal injections ineffective
25
Q

maxillary labial bone is:

A

porous

26
Q

describe local infiltration/ supraperiosteal injection

A

-insert superior to root apex
- orient needle bevel towards bone
- inject 0.6 mL of anesthetic

27
Q

what areas are anesthetized in supraperiosteal injection

A

-tooth
- buccal periodontium and bone
- labial or buccal mucosa

28
Q

what are the indications for supraperiosteal injection

A
  • procedures on one tooth
  • soft tissue surgery in a small area
29
Q

what are the advantages and disadvantages supraperiosteal injection

A

-advantages: simple and high success rate
- disadvantages: not useful in inflamed area, large volumes needed to treat multiple teeth

30
Q

how do you do a greater palatine nerve block

A
  • path of insertion
  • locate foramen with cotton tip
  • apply topical for 2 minutes
  • move applicator over foramen: apply direct pressure for 30 seconds
  • place needle bevel against tissue and bow the needle
  • administer a few drops of local
  • straighten and advance the needle
  • contact bone
  • aspirate, deposit 0.45 to 0.6mL
31
Q

what areas are anesthetized in the greater palatine nerve block

A
  • posterior portion of hard palate
  • overlying soft tissues
  • no anesthesia of teeth
32
Q

what are the indications of the greater palatine injection

A
  • when palatal soft tissue anesthesia is needed - extractions, sub gingival restorations
  • pain control during periodontal or oral surgical procedures
33
Q

how do you do a nasopalatine nerve block

A
  • apply topical for two minutes lateral to papilla
  • apply direct pressure
  • contact bone, administer 0.45 mL
34
Q

describe the nasopalatine nerve block- trans papillary approach

A

-apply topical lateral to frenum
- blanching of labial tissue
- insert through papilla towards palate
- administer 0.3mL into papilla

35
Q

what are the areas anesthetized with nasopalatine nerve block

A
  • anterior portion of hard palate
  • both hard and soft tissues
  • no anesthesia of teeth
36
Q

what are the indications for nasopalatine injection

A
  • when palatal soft tissue anesthesia is needed - extractions, subgignvial restorations
  • pain control during periodontal or oral surgical procedures
37
Q

what are the approaches for the maxillary nerve block

A
  • high tuberosity approach
  • greater palatine canal approach
38
Q

what advantages or disadvantages of the high tuberosity approach for the maxillary nerve block

A
  • advantages: atraumatic, 95% success rate, minimizes volume of local
  • disadvantages: risk of hematoma, absent bony landmarks, lack of hemostasis
39
Q

what are the advantages and disadvantages of the greater palatine canal approach for the maxillary nerve block

A

-advantages: usually atraumatic, 95% success rate, minimizes volume of local
- disadvantages: lack of hemostasis, potentially painful injection
