IDB Technique Materials •  •  •  •  •  •  •  •  •  •  •  •  •  •  • 

Avex Brackets! Aisler or Alcote Separator! Thick Brush for Separator! Red and Black Mechanical pencils! Zand gauges! Boley Gauge! Affinity Crystal Clear! Opal Seal! Opal Bond MV! Opal Bond Flow! McLaughlin IDB placement chart! Clear Rope wax! VALO Ortho or VALO Cordless curing light! Plastic Sheet Protectors! Black model boxes


•  With a black mechanical pencil (0.5) draw a line down the centre of the tooth to the end of the root


IDB Technique •  Using a boley gauge measure the clinical crown length of the central incisor and divide by 2 • 

Refer to the McLaughlin IDB placement chart for the measurements of the horizontal guide line


•  Use the appropriate Zand Gauge to mark the horizontal guide lines on the facial surface, not marking the premolars


•  With a red mechanical pencil draw a line across the facial surface of the premolars and molars connecting the mesial and distal marginal ridges


•  Using the boley gauge measure the distance between the red and black lines on the molars and record the measurement


•  The distance between the red and black lines on the molar is then brought to the premolars and a black line is placed the same distance below the red


IDB Technique • Apply a tinfoil substitute (separator) such as Alcote or Aisler to model and wait until dry.! • Drying can be done quickly by using a hair dryer or compressed air


•  • 

Next coat the under surface with OpalBond MV! PLEASE NOTE: If using Avex ceramic brackets, a thin coating of OpalSeal must be applied to the base of the bracket prior to the adhesive.


•  Place the bracket on the model lining up the midline marking on the bracket with the vertical line on the model and the slot with the horizontal line and repeat with remaining brackets •  Do not light cure until all brackets have been placed

!


Place brackets and clean off excess adhesives. Then place models in a black box until final bracket placement is approved by the orthodontist.


•  When bracket placement has been verified, cure directly over each bracket for 3 seconds each with VALO Ortho in Xtra Power mode.


•  Using a clear rope wax create a border for your matrix


•  Using a clear rope wax create a border for your matrix


!

•  Express Crystal into borders created with rope wax •  Place on labial, buccal, occlusal and palatal surfaces


!

•  Express Crystal into borders created with rope wax •  Place on labial, buccal, occlusal and palatal surfaces

•  Express Crystal into borders created with rope wax •  Place on labial, buccal, occlusal and palatal surfaces


!

•  Express Crystal into borders created with rope wax •  Place on labial, buccal, occlusal and palatal surfaces


• 

To make the matrix smooth roll the long plastic sheet to facial surface with gentle pressure


• 

Next roll the square plastic sheet to the occlusal surface with gentle pressure, than wait until set


• 

Once Crystal is set remove plastic


IDB Technique

•  Place model in a bowl of warm water for 15-20 minutes, this allows the separator to release the brackets from the model.


•  Press firmly downwards on buccal and labial aspect of the matrix to release the brackets from the model, if they do not release reach under matrix with a plaster knife.

!


•  Using ORTHO Prophy SA-85 blast the undersurface of the brackets to clean off excess separator or stone

!


IDB Technique •  Now the matrix and brackets are ready for indirect placement.! •  Bonding Procedure! 1. Etch entire facial surface of enamel and rinse! 2. Apply OpalSeal Primer to the entire facial surface ! 3. Apply OpalBond Flow to undersurface of brackets! 4. Place matrix in mouth and cure 3 seconds per bracket with Valo Ortho in Xtra Power mode! 5. Remove Matrix and cure each bracket again for 3 seconds with Valo Ortho in Xtra Power mode
