Modern
concept for partial restoration of pulpless teeth |
|
| |
|
|

Endodontically treated teeth are very often the
subject of a systematic prosthetic treatment that does not take
into account the amount of loss of the coronal tooth material. Enhancement
of our knowledge concerning non vital teeth, advances in the field
of biomaterials and a longer span of life increase the potential
for retreatment thus leading to a relevant alternative choice for
the classical crown. So, Dr F.BUKIET and I devised the Restaurations
Partielles Collées (R.P.C) or Partially Bonded Restorations.
Those restorations follow the guidelines of modern odontology: conservation
and adhesion: :
|
|
| |
* Less mutilation of dental tissues.
* Quality immediate temporization in endodontics or periodontology.
* Ease of reintervention for endodontics.
* Periodontally less aggressive.

Field of indication for RPCs on non vital teeth
will be analysed from a set of parameters among which loss of tooth
substance will be essential (volume, architecture and localisation).
RPCs whether in the anterior or posterior region can be elaborated
with different materials: ceramics, composite, fibre or metal reinforced
composite, metal. These restorations will be cemented or bonded.Our
presentation will show different clinical cases with their rationale.
Nevertheless those new techniques are not yet sufficiently proven
in the clinic. Multicentric prospective studies seem to be necessary
to test their long term reliability as well as many other techniques
now in use
