Q

How do the couplands help with extracting?

A
  • Curved surface placed against flat of the tooth and PUSH APICALLY.
  • SEVERS THE ALVEOLAR CREST FIBERS AND WIDENS THE LABIAL PLATE –> MAKES SOCKET WIDER THAN TOOOTH AND ALLOWS FORCEP BEAKS TO GO DEEPER.

Q

How can the Couplands be used to extract?

A
  • Place couplands at mesial/ distal between the TOOTH and the ALVEOLAR CREST and push APICALLY then switch position of handle to 90 degrees.
  • Turn in a CLOCKWISE direction.
17
Q

What is the preferred instrument for extracting lower 3rd molars?

A

Couplands at 90 degrees

18
Q

When are couplands at 90 degrees not recommended?

A

when there is a tooth behind as the forces get pushes distally.

19
Q

What size couplands would you use for lower incisors?

A

smallest size.

20
Q

A

medium size?

21

A

medium size.

22
Q

What size couplands would you use for molars?

Largest size.

23
Q

What are the functions of the luxator (general).

A

ONLY used to FACILITATE THE ENLARGEMENT OF THE SOCKET.

24
Q

How are Luxators used?

A
  • used along VERTICAL AXIS of tooth and PUSH apically.
  • DO NOT TWIST (as already curved - no point in twisting) and NEVER USE AT 90 DEGREES.
25
Q

What is the best instrument for extraction of lingually or palatally impacted premolars?

A

Warwick james.

26
Q

What is the best instrument when extracting in tight spaces?

A

Warwick James.

27
Q

How are Warwick james used (4 steps).

A
  1. Place blade of the cryers interproximally on the SURFACE OF THE TOOTH YOU WANT TO EXTRACT.
  2. Push apically so the blade engages the tooth you want to remove and the alveolus.
  3. Push the blade of interproximal with supporting hand and secure the blade of the tooth with your non dominant hand.
  4. Rotate the blade which pushes the tooth BUCCO-DISTALLY. Can EXTRACT a tooth like this.
28
Q

How are Cryers used?

A
  1. Place blade of the cryers interproximally.
  2. Push apically so the blade engages the root of the tooth.
  3. Secure the blade of the tooth with your non dominant hand.
  4. Rotate the blade which pushes the tooth BUCCO- DISTALLY. Can EXTRACT a tooth like this.
29
Q

What 2 cases are warwick james useful for?

A

Impacted premolars

Tight spaces

30
Q

What instrument is best indicated for extraction of upper third molars?

A

Cryers.

31
Q

What instrument is best indicated for retained roots?

A

Cryer forceps.

32
Q

How can a distal retained root of a lower 1st molar be removed?

A

Place cryers mesially into the socket and turn the blade to break inter-radicular septum. This creates a point of application on the distal root and that elevates the distal root.

33
Q

What are 2 indications for cryers?

A
  • Extraction of upper 3rd molars.
  • Retained roots.
34
Q

What determines if a tooth can be elevated?

A
  • Root morphology. Simple conical roots are easier to elevate.
