Does a Highly Filled Injectable Resin Composite Work Better Alone or in Combination With a Nanohybride Resin Composite?
Sponsor: Tolunay Aytas
Summary
This is a double blinded, randomized clinical study that evaluated the performance of a high filled injectable resin composite in polydiastema . The polydiastema disorders will be restored with high filled injectable resin composite (G'aenial Injectable Universal ) or anterior composite resin (G-aenial A'chord ). Restorations will be evaluated after 12 months according to FDI criteria and the data will be analyzed.

Interventions
Nanohybrid Composite (G-ænial A'Chord, GC Corp., Tokyo, Japan)
Conventional nanohybrid resin composite (G-ænial A'Chord, GC Corp., Tokyo, Japan) was used for direct anterior veneer restorations. The material was applied using a free-hand layering technique following digital smile design and wax-up. A transparent silicone index (Exaclear, GC Corp.) was used for shape guidance when necessary. The enamel surfaces were etched with 37% phosphoric acid and bonded with a universal adhesive (G2 Bond, GC Corp.) before composite application. This intervention represents the standard clinical technique for direct composite veneers and serves as the active comparator group.
Highly Filled Injectable Composite (G-ænial Universal Injectable, GC Corp., Tokyo, Japan)
Highly filled flowable injectable composite resin (G-ænial Universal Injectable, GC Corp., Tokyo, Japan) was used either as a sole restorative material or in combination with a nanohybrid composite for direct anterior veneers. For the injection process, a transparent PVS index (Exaclear, GC Corp.) was fabricated from a wax-up model and used to guide the placement of the material. In the combined technique, a 1-mm palatal layer of nanohybrid composite was placed first, followed by the injection of the flowable composite. The procedure aimed to improve adaptation, minimize voids, and optimize esthetic results compared to the conventional layering method.
