Q

Passive Vs Active Clamps

A

Passive Clamps:

  • flat
  • no anesthesia needed
  • placed above gingival margin
  • cause minimal gingival trauma

Active Clamps:

  • narrow, curved
  • anesthesia needed
  • placed below gingival margin
  • can displace gingivae

Q

Winged Clamps Vs Wingless Clamps

A

Winged Clamp

  • endo use
  • interference w/ wedge and matrix
  • more retraction

Wingless Clamp

  • restorative use
  • less retraction
  • no interference w/ wedge and matrix

Q

Cervical retracting clamps

A
  • used in conjunction with a major anchor clamp
  • have small gripping power and so retention is provided mainly by impression compound
  • have limited life
  • single-bowed or double-bowed
  • jaws are movable even after attaching the clamp to the tooth

Q

Ivory Vs Stokes clamp forceps

A

Ivory clamp forcep:

  • prevents clamp rotation
  • it limits the use of these forceps to teeth that are within a range of normal angulation

Stokes clamp forcep:

  • rotation of clamp
  • has notches near beak tips
17
Q

Floss uses:

A
  • to tie the clamp and prevent the patient from aspirating or swallowing it
  • For testing the interproximal contacts
  • For passing the dam interproximally
  • For making ligatures when needed
  • For inverting the dam
18
Q

Floss uses:

A
  • to tie the clamp and prevent the patient from aspirating or swallowing it
  • testing the interproximal contacts
  • passing the dam interproximally
  • making ligatures when needed
  • inverting the dam
19
Q

What is single tooth isolation used for?

A
  • fissure sealants
  • class I and V restorations
  • endodontics
20
Q

What is multiple tooth isolation used for?

A
  • class II restorations
  • bonding indirect restorations
  • multiple restoration and quadrant dentistry
21
Q

What are the rules for multiple tooth isolation?

A

General rule: at least 1 tooth posterior and 2 anterior to the one being treated

Incisors: P to P
Canine: M1 to opposite I2
Premolars: 2 teeth distally to opposite I2
Molars: opposite I2 to as D as possible

22
Q

Clamp first

A
  • winged or wingless clamps
  • no M3
  • tightened w/ floss
  • easier than clamp and dam together
  • improved visibility
  • reduces the risk of traumatizing the gingival tissues
23
Q

Clamp and rubber dam together

A
  • M3
  • limited visibility
  • winged or wingless clamps
  • solves the difficulty of trying to pass the dam over a previously placed clamp
24
Q

Clamp, rubber dam and frame all together

A
  • winged clamp only

- limited space for stretching the rubber dam

25
Q

No clamp

A
  • for anteriors
  • less retraction provided
  • no risks associated w/ the use of clamps
26
Q

Spint dam

A
  • used when isolating a badly broken down tooth, the abutments of a bridge, partially erupted teeth, teeth with deep subgingival margins, anterior teeth and when preparing teeth for full crowns
  • essential to apply a sealing material to seal the voids and prevent leakage and contamination
  • 2 overlapping holes punched on dam or the dam is slit cut between the holes made for 2 adjacent teeth
