Clinical DENTAL TRIBUNE | OCTOBER 1-7, 200710
The PROBLEM is: How to restore a tooth that has
been endodontically treated. We see
many of these teeth in our practiceson a regular basis. We require a sim-plified and clinically proven tech-nique is required to restore theseteeth predictably. In many cases,much of the coronal tooth structurehas been lost to decay or to en-dodontic access, and the tooth is es-
sentially a remaining readicularstructure with little coronal toothshowing beyond the gingival mar-gin. Over the last decade, innovativeand increasingly stronger tech-niques and materials have simpli-fied this procedure and made it arapid and predictable clinical
process. The bonded post and corerestoration is compatible with anyendodontically treated tooth andcompatible with all types of crownsthat may be used to restore the toothto optimal form and function.

8. The ParaPost Taper Lux is inserted fully into the canal (thecolored sizing ring has been previously removed)
6. The bonding agent is applied into the canal and (inset) onthe remaining dentin as well
7. ParaCore Dentin shade is injected into the canal from bot-tom to top
3. The size-associated reamer is used to re-prepare the canalto the proper length
4. The ParaPost Taper Lux is tried into the proper depth
13. The post and core is now complete (buccal view)11. Additional ParaCore Dentin is immediately added to formthe full dimensions of the core
12. Once the core has been shaped to the required dimension itis light cured (inset)
9. The lubricated HuFriedy interproximal contact curing instrument is used to begin forming the core 10. The surface composite is light cured

5. The remaining radicular tooth structure is etched thoroughly.It is then washed and dried.
The SOLUTION is:
The long and complex post andcore procedure has been reduced toa simplified technique that utilizesthe post and core material as thepost cement as well. In order for thistechnique to function, the core mate-rial must be a dual cure compositeresin which will in the depths of thecanal around the deepest portions ofthe post, cure within 5-6 minuteseven though no light can actuallyreach it. Thus the post and core pro-cedure can be reduced to 15 minutesor even less in most situations. DT
