clinical performance of short fiber reinforced resin composite versus indirect nanohybrid resin composite onlay restorations in complex proximal cavities of molar teeth will be evaluated over one year.
Resin composite materials have been rapidly developed in the latest few years. Direct resin composite restorations become the golden standard for restoring intracoronal cavities. While for the extracoronal cavities, the indirect resin composite onlays tend to replace metallic restorations in most situations being more esthetic and conservative with lower cost (Rocca \& Krejci, 2007).
Indirect resin composite onlays usually are lab processed in two appointments but it can be made in one appointment through CAD/CAM technology or by flexible model technique (semidirect technique).
These restorations offer more control on the proximal contacts and the anatomic form over the direct approach. Polymerization shrinkage occurs outside the patient mouth so the stresses are decreased and become limited to the width of the luting space. Annual failure rate (AFR) of indirect posterior resin composite restorations is up to 10% (Manhart et al, 2004).
One of the advancement in resin composite technology is the evolution of short fiber reinforced resin composite (SFRC) material that allows making a direct onlay restoration possible thus offers less procedural steps and saves more time (Garoushi et al, 2013).
This material is made to be used as a dentine substitute in the high stress-bearing areas. It is covered by a conventional resin composite filling to act as the enamel replacement this combination gives us a kind of biomimetic restoration.
Exclusion Criteria:
Short fiber reinforced resin composite restoration (Ever X Posterior, Gc Europe) that is used in high stress bearing areas as direct onlay restoration.
Other: Ever X Posterior
Nanohybrid resin composite (GrandioSO, VOCO GmbH Germany ) that can be used to make indirect restorations in posterior teeth.
Other: Ever X Posterior
Resin composite restoration can be made as a direct onlay
Also known as: Short fiber reinforced resin composite
Change in the Clinical performance
Measured using modified USPHS criteria for clinical evaluation of restoration failure
Time frame: Change from the Baseline at six months and 12 months.
