Summary

injectable resin composite technique will show a better clinical and esthetic performance compared to conventional layering resin composite technique in patients with multiple spacing in the maxillary anterior teeth area or not.

Detailed description

The injectable composite resin technique is an indirect/direct method that uses a transparent silicone index for accurate and predictable translation of diagnostic wax-up into composite restorations without the need for tooth preparation. The injection molding technique has the advantage of replicating the excellent anatomy defined by a lab-made diagnostic wax-up whereby it would be used for the fabrication of direct restorations, so excellent anatomy results, verifies aesthetics, phonetics, and occlusion, avoids misunderstandings, as it is easy to implement and repair.

Interventions

Type	Name	Description
PROCEDURE	Injectable resin composite technique.	A metal impression tray was filled with transparent vinyl polysiloxane (EXACLEAR, GC) and used to copy the stone model with the wax-up. Then, the replica will be separated from metal tray and a needle-shaped bur will be used to drill holes through the silicone key ending in the middle of the incisal edge. It will be checked whether the holes were large enough to enable the tip of the composite syringe to pass easily and completely. Neighbouring teeth (mesial and distal one) isolated using Teflon tape, as each tooth will individually be restored for establishment of satisfactory contact points. Following etching and rinsing, the tooth dried, and a dental cord (Ultrampak, Ultradent) will be packed into sulcus for mechanical prevention of subgingival composite flow. Then, the transparent silicone index will be placed in the correct intraoral position, and a syringe filled with flowable composite will be inserted through the hole on the incisal edge.
PROCEDURE	Conventional layering technique	the palatal surface will be restored by enamel shade; adapted on the index in the spacing area then The Unica matrix (Polydentia) will be used to restore the proximal wall, and to achieve a good seal with the palatal wall. The matrix can be stabilized with a wedge if necessary. Building the proximal wall using the enamel shade, and the incisal halo by using a dentin shade, the frame to layer the core of the restoration will be ready.
