Injection Molding Technique

Details and patient eligibility

About

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.

Full 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.

Enrollment: 20 estimated patients

Sex: All

Ages: 20 to 45 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

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.

Spacing in the maxillary anterior teeth area treated with injectable resin composite technique.

Experimental group

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 Spaces will be restored with injectable resin composite.

Treatment:

Procedure: Injectable resin composite technique.

Spacing in the maxillary anterior teeth area treated with conventional layering composite technique.

Active Comparator group

Description:

shade mapping of enamel and dentin, then isolation the teeth with rubber dam. Palatal index will be done on waxing up and applied against the palatal surface to check the adaptation of the index. Then, the enamel shade adapted on the index in the spacing area. index will be placed back on the anterior teeth to build the palatal wall. A brush will be used to adapt the composite to the margin. After removing excess material, light curing will be carried out for 20 seconds. 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.

Treatment:

Procedure: Conventional layering technique
