Exodontia: Slides Flashcards
Last tooth in arch is mobilized with…
Straight elevator
What is ALWAYS used when performing and extraction
Gauze throat pack
How many steps are there in a routine extraction
5
All should be considered, but some can be skipped in certain situations
What is general step 1 of an extraction
Loosen soft tissue
What instrument(s) do you use to loosen soft tissue
1 Woodson Elevator
Periosteal elevator (Moldt #9)
What is step #2 of a routine extraction
Luxate tooth with elevator
What instrument is used to Luxate tooth
Usually the small straight elevator #301
What should be used as a fulcrum
The bone, not the adjacent teeth
What is step 3 of a routine extraction
Adapt Forceps to Root
Seat lingual beak first
Position beaks apically under soft tissue
Grasp root
Keep beaks of forceps parallel to root
Sub steps to General Step 3 (Adapt Forceps to Root)
As beaks are worked ______, bone ______ and movement of tooth out of socket may even begin
apically, expands
What is step 4 of a general extraction
Luxate tooth with forceps
- Strong apical pressure
- Slow, firm pressure
- Buccal first and most (usually), alternate buccal and lingual pressure
- Always apical pressure, with some combo of
Luxation
Rotation - Reapply apical pressure
Substeps of General Step 4 (Luxate tooth with Forceps)
What is general step 5 in a routine extraction?
Remove tooth from socket
- Gentle traction, usually toward buccal
- Luxation or rotation must first
expand socket
Disrupt periodontal ligament - Teeth are never removed by “pulling”
Substeps of General Step 5 (Remove tooth from socket)
What does socket debridement mean
Remove granulation tissue with curette
Irrigate if debris is present
- Debride if needed
- Check for sharp bone margins, smooth if needed (bone file/Rongeur)
- Trim excess gingiva
- Place gauze for pressure over extraction site
- Consider suture if papillae significantly loosened
Steps of Closure
General Order of Extraction
Maxillary First
Posterior First
Most difficult (First or Last?)
Symptomatic teeth first if an doubt re: ability to complete procedure in a single setting
What can occur if you over-luxate the tooth?
Buccal plate fracture
Root fracture
What direction are you moving the tooth when you talk about traction
Incisally out of the socket
- No absolutes, just general principles
- Position self based on good ergonomics and ability to apply controlled, effective forces
- Palm up and palm down grip on forceps both have applications
- Patient position may vary with chair design
- Most operators stand, though some are effective with seated technique
General Rules for Patient and Operator Positioning
General Guideline for Patient Positioning for Maxillary Teeth
Patient semi-reclined so that maxillary oclusal plane is about 60 degrees to the floor
height should be at elbow level
General Guidelines for patient positioning for mandibular teeth
Patient somewhat upright, so that lower occlusal plane is nearly parallel to floor
Height adjusted so the arms are comfortable bent (could be elbow level or below)
Specific technique for Mx First Premoalrs
Gentle buccal/palatal luxation
