custom made provisional restoration
CUSTOM MADE PROVISIONAL RESTORATION
  • THIS RESTORATION IS FABRICATED TO REPRODUCE THE ORIGINAL CONTOURS OF THE TOOTH
  • AN IMPRESSION OF THE PREPARED TOOTH IS MADE AND A CAST IS POURED
  • PREPARED TOOTH ON THE CAST IS WAXED UP AND CARVED TO REPRODUCE THE ORIGINAL CONTOURS

PREFORMED PROVISIONAL RESTORATION
  • THESE ARE COMMERCIALLY AVAILABLE PREFABRICATED CROWNS
  • AVAILABLE IN VARIOUS SIZES
  • OPERATOR CHOOSES THE BEST ONE SUIT TO THE PATIENT
  • BEFORE CEMENTATION THESE CROWNS ARE SLIGHTLY ALTERED AND MODIFIED TO FIT THE TOOTH

1.COMMONLY DONE WITH ALGINATE IMPRESSION MATERIAL

2.OVERIMPRESSION CAN BE MADE FROM THE PATIENTS MOUTH OR FROM THE DIAGNOSTIC CAST.

3.WHEN THE ALGINATE HAS SET OVERIMPRESSION IS REMOVED AND CHECKED FOR COMPLETENESS.

www.rxdentistry.net

slide28
4.THIN FLASHES OF IMPRESSION MATERIAL THAT REPLICATE THE GINGIVAL CREVICE ARE REMOVED TO INSURE THAT NO IMPEDIMENT TO THE COMPLETE SEATING OF THE CAST INTO THE OVERIMPRESSION LATER.

5.IMPRESSION IS THEN WRAPPED IN A WET PAPER TOWEL AND PLACED IN A ZIPLOCK PLASTIC BAG FOR LATER USE.

slide29
6.WHEN THE TOOTH PREPARATION IS COMPLETED,ANOTHER QUADRANT IMPRESSION IS MADE WITH ALGINATE

7.THIS IMPRESSION IS THEN POURED WITH A THIN MIX OF QUICK SETTING PLASTER.

8.THEN TRY TRIMMED QUICK SET PLASTER CAST IN THE OVERIMPRESION TO MAKE SURE THAT IT WILL SEAT COMPLETELY

www.rxdentistry.net

slide30
9.COAT THE PREPARED TOOTH AND ADJACENT AREAS OF THE CAST LIBERALLY WITH A “TIN FOIL SUBSTITUTE” SEPERATING MEDIUM

10.MIX TOOTH COLORED ACRYLIC RESIN IN A DAPPEN DISH WITH A CEMENT SPATULA

11.PLACE THE RESIN IN THE OVERIMPRESSION SO THAT IT COMPLETELY FILLS THE CROWN AREA OF THE TOOTH

slide31
.

.

12.SEAT THE CAST INTO THE OVERIMPRESSION ,MAKING SURE THAT THE TEETH ON THE CAST ARE ACCURATELY ALIGNED WITH THE TOOTH IMPRESSION.

13.FORCE USED TO SEAT THE CAST INTO THE ALGINATE IMPRESSION IS CRITICAL.EXCESSIVE FORCE CAN OVERSEAT THE CAST AND UNEVEN FORCE CAN TORQUE THE CAST.

14.ONCE THE CAST HAS BEEN FIRMLY SEATED HOLD THE CAST IN PLACE WITH A LARGE RUBBER BAND

www.rxdentistry.net

slide32
15.PLACE THE OVERIMPRESSION-PLASTER CAST ASSEMBLY IN A PLASTER BOWL FULL OF HOT TAP WATER OR APPROX. 5 MIN OR INTO A PRESSURE POT UNDER 20 PSI.

16.WHEN THE RESIN HAS POLYMERISED.REMOVE THE RUBBER BAND TO DISASSEMBLE IT.
