What is this instrument? and use?
- Molt Currettes: 2 and 4
- straight instruments
What are the options for holding the mouth open? Why/when to use?
- Use when/why:
- Extractions on mandibular teeth
- supports mandible to prevent stress on TMJ (protect)
- Extractions on mandibular teeth
- Silicone Bite Blocks
- Molt Mouth Prop
What is this instrument? and use?
- Silicone Bite Block
- hold mouth open
What is this instrument? and use?
- Molt (side-action) mouth prop
- open mouth wider
- Useful for:
- deeply sedated patients
- mild trismus
What is this instrument? and use?
- Towel Clip
- hold towels and drapes In position
What is this instrument? and use?
- Monojet Syringe
- irrigating
- When hand piece and bur used to remove bone
- cools the bur and prevents build up of bone-damaging heat
- increases efficiency
- washes bone chips from flutes
- after completion of surgical procedure and before suturing=irigate
What is this instrument? and use?
- No. 9 Molt periosteal elevator
- used to raise full thickness flap after mucoperiosteal incision
- Pointed End
- begin periosteal reflection
- reflect dental papillae b/w teeth
- Broad/rounded end
- continue the elevation of periosteum from bone
- Push Stroke=most efficient
Retractors: function & types/names
- Fxn:
- Retract cheeks, tongue, and flaps
- provide access and visibility
- protect soft tissues from sharp cutting instruments
- Before flap is created→ in cheek
- reflect flap→edge on bone and retract flap
- Types:
- Austin
- Minnesota
- Seldin
- Weider/Sweet heart
What is this instrument? and use?
- Austin Retractor
- Right Angle
- Retract cheek, tongue or flaps
What is this instrument? and use?
- Minnesota retractor
- offset
- retract cheeks and flaps
What is this instrument? and use?
- Seldin (bottom)
- leading edge is not sharp
- dont elevate mucoperiosteum
- retract soft tissues
- Henahan (bottom)
What is this instrument? and use?
- Weider/Sweet heart
- tongue retraction
- dont position to posterior=gag
What is this instrument? and use?
- Hemostat
- control hemorrhages and dissection
What is this instrument? and use?
- Fraser suction tip
- place finger over hole→increase suction
What is the purpose of suctioning?
- visualization
- suction blood, salt a, and irrigating solutions from site
- Surgical suction
- orifice-rapid evacuate fluids from site
- soft tissue wont aspirate into suction hole→prevents injury
- orifice-rapid evacuate fluids from site
Purpose of using dental elevators?
- luxe teeth from surround bone
- easier to remove w/dental forceps
- minimize broken roots, teeth, and bone
Indications for use of elevators
- Luxate teeth before forceps
- luxate or remove teeth that cant be grasped by forceps
- impacted teeth
- malposed teeth
- fragile
- cervical caries
- Forceps. might cause ttrauma
- root removal
Rules of Elevator use
- Never use adjacent teeth as fulcrum
- unless tooth is being extracted
- Control movements to avoid slipping
- damage soft or hard tissues
Straight Elevators
- most commonly used to luxe teeth
- Small straight: No 301
- begin lunation of erupted tooth
- Large Straight: No 34:
- displace roots from socket
- luxate teeth when
- spaced wide
- small straight is less effective
- Cryer elevator-most common
- Aka East West elevators
- Remove broken root
- when adjacent socket is empty
What is this instrument? and use?
- Crane Pick
- elevate whole roots or teeth after purchase point has been prepped w/bur
What is this instrument? and use?
- Root tip pick (apex elevator)
- small root tips from sockets
- vertical displacement concept→tip into PDL
