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.

Medical and Biotech [MESH] Definitions

Inability or inadequacy of a dental restoration or prosthesis to perform as expected.

The degree of approximation or fit of filling material or dental prosthetic to the tooth surface. A close marginal adaptation and seal at the interface is important for successful dental restorations.

A prosthesis or restoration placed for a limited period, from several days to several months, which is designed to seal the tooth and maintain its position until a permanent restoration (DENTAL RESTORATION, PERMANENT) will replace it. (From Jablonski, Dictionary of Dentistry, 1992)

The process of repairing broken or worn parts of a PERMANENT DENTAL RESTORATION.

An operation in which carious material is removed from teeth and biomechanically correct forms are established in the teeth to receive and retain restorations. A constant requirement is provision for prevention of failure of the restoration through recurrence of decay or inadequate resistance to applied stresses. (Boucher's Clinical Dental Terminology, 4th ed, p239-40)
