Background summary
After endodontic treatment, a good coronal seal is a prerequisite for long term
success. There are several methods of establishing such a coronal seal and
restoring the function of a tooth: 1) a direct restoration made of composite
and 2) an indirect restoration made of indirect composite, glass ceramic, high
performance ceramic or metal-ceramic.
In the past, indirect restorations on endodontically treated teeth were often
supported by a post-and-core build-up. However, this requires a post
preparation, which further weakens the tooth.
Endocrowns are a viable alternative to the traditional post-and-core build-up
in severe structurally compromised molar teeth. Endocrowns are monolithic
restorations that extend into the pulp chamber of endodontically treated teeth
with severe loss of coronal hard tissue. An endocrown can be made directly
(composite) of indirectly (porcelain).
In the case of severe structurally compromised molar teeth where no or only a
single coronal wall remains that require restoration, the clinician and patient
have to consider treatment alternatives in relation to costs and durability.
Indirect restorations are relatively costly and frequently overstretch the
patients* financial budget, particularly immediately after an (expensive)
endodontic treatment. The possible alternative could be a directly made massive
composite build-up. This is a clinical challenge since it is difficult to
provide proper marginal adaptation and adequately restore anatomical form
directly in the mouth.
There is a lack of evidence concerning the survival and clinical performance of
the aforementioned two restoration types.

Study objective
To investigate the performance of indirect glass ceramic and direct composite
endocrowns in the restoration of severe structurally compromised endodontically
treated molar teeth.
Study design
Randomised 5-year clinical study and evaluation of direct versus indirect
endocrowns fabricated on endodontically treated molars.
Intervention
The patient will be allocated at random to a direct or indirect endocrown.
Direct endocrowns will be fabricated in one session using composite. During the
indirect procedure, a preparation will be made and subsequently scanned. The
restoration will be milled in dental laboratory. In a second session the
restoration will be cemented onto the molar.
Study burden and risks
No additional risks are anticipated. Both treatment modalities are being used
nowadays in the clinic. Clinical data are collected during regular checkups, no
different from the usual clinical procedure. The process of collecting data for
the research is only little extra time consuming and is anticipated to be an
extra hour, with one extra session involved.
