SonicFill™ 2 System
From placement to polished restoration in less than 3 minutes
The potential benefits of bulk-fill composites are obvious. They offer faster and easier placement, simplifying one of the most time-consuming and tedious tasks in dentistry. However, some clinicians are rightly concerned that bulk-fill products may hinder the quality of their restorations, which is an unacceptable tradeoff.
Certainly, there are specific features any bulk-fill product must offer to alleviate these concerns. First, a bulk-fill product must achieve intimate adaptation with the often complex internal cavity surface. Failure to achieve this adaptation could result in gaps between the tooth/adhesive layer and the resin composite, which in turn present potential clinical problems or failures.
Adequate curing is essential to maximize the mechanical properties of the composite and reduce patient exposure to uncured methacrylate monomers, which can irritate oral tissue. Most materials can be reliably cured to 2 mm with a high-powered curing light, so a bulk-fill must cure beyond this depth. All composites shrink, and the force created by this volume loss can cause debonding, cuspal flexure, or both. Debonding may eventually lead to recurrent decay, and cuspal flexure could cause microfractures in the tooth and/or postoperative sensitivity. Bulk-fill resins must offer an equal, or even decreased, level of shrinkage stress compared to a conventional material placed in layers.
Beyond these three requirements, a bulk-fill resin must satisfy all the performance requirements that clinicians have come to expect of restorative composites. This includes adequate mechanical properties and esthetics acceptable for the application. Adaptation, depth of cure, shrinkage stress, mechanics, and esthetics provide a good framework for considering a bulk-fill product.
SonicFill 2 has been designed to meet all of the requirements with a single application of a single material. The system consists of a handpiece that applies sonic energy while dispensing a unique composite with modifiers that react to the sonic energy, greatly improving adaptation and reducing shrinkage stress. SonicFill 2 can be placed in increments of up to 5 mm. It offers excellent adaptation, low shrinkage stress, high depth-of-cure, improved strength and wear resistance, and outstanding color match and polishability.
