RESINS

Composite resins have become the material of choice for aesthetic restorations. Many clinicians have developed different adhesive techniques which we will be mentioning below.

Adhesive Techniques

Composite resin restorations require modern adhesive placement techniques that allow for more natural aesthetics. Also the ability to place minimal invasive restorations that conserve more natural tooth structures. That is as compared to other restorative choices.

Con­traction and shrinkage stress are major disadvantages of composite resin materials. The polymerization of composite resins gives rise to internal stresses. This is due to contraction of the material during polymerization. Shrinkage stress occurs when the material can’t contract. Or it has already hardened enough to prevent the flow of plastic compensation.

Composite resins are often used in replacing defective amalgam fillings. Yet clinical challenges can also be linked to these materials. Like recurrent caries, dental and material fracture, and postoperative sensitivity occur via structural failures. Inherent in the composites themselves, originating from the polymerization shrinkage. Able to cut any associated problems manufacturers have focused their attention on producing materials.

Composite resins and adhesive techniques have changed the approach to teeth restorations. This has improved the performance of the composite restoration in posterior teeth. As well as reduced the operative time required for placement. A new class of bulk-fill resins was recently introduced in the market. This material advancement allows the clinician to place a single layer of the composite. This is 4.0 to 5.0 mm thick. Then light cured in a single step. Microleakage compared to different bulk-fill resins concluded that these have adequate cave surface sealing. That is like that of conventional resins applied in the incremental technique.

Devices

The recent introduction of SonicFill continues in this direction. This system combines the attributes of low flowable viscosity and standard universal viscosity. These are materials in the same nanoparticle-resin. Also this incorporates about 83.5 wt% fillers with specific components that react to sonic energy.

Applied sonic energy; the viscosity of the composite decreases up to 87%. This causes the resin to flow. By activating the resin with ultrasonic energy and increasing the flowability. It makes it possible to fill the cavity. At the end the consistency of the composite changes back to a higher viscosity.  This is ideal for compressing and shaping posterior Class I and II restorations. As well as for the reconstruction of cusps as well as a cavity base after endodontic treatment. The well-designed long handpiece allows for easy access in the molar area.15

The use of SonicFill device. In the creation of 2 single-increment composite restorations in posterior teeth.

Finally, the SonicFill system is an efficient technique. Convenient of use and reliable when used for restoration of cavities in posterior teeth. This system demonstrates improved handling characteristics with excellent material consistency. It is also able to sculpture any restoration with favorable marginal adaptation. As well as provide patients with quality composite resin restorations.
