Esthetic and Clinical Assessment of Injectable Resin Composite Technique

Esthetic and Clinical Assessment of Injectable Resin Composite Technique Compared to Conventional Layering Technique in Patients With Multiple Spacing in the Maxillary Anterior Teeth Area.

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.

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.

Inclusion Criteria:

• Sound and vital upper anterior teeth.
• Spacing in the maxillary anterior teeth area ranging from .5mm to 2mm.
• Minor misalignment, correction of peg laterals.

Exclusion Criteria:

• Non-vital, fractured, or cracked teeth.
• Teeth with caries or in need of replacement of existing restorations.
• Rampant caries, atypical extrinsic staining of teeth.
• Heavy occlusion and occlusal contacts or history of bruxism.
• Severe periodontal affection.
