Restore your love for Class II Procedures

Every year, a large percentage of your patient base will receive a Class II restoration, providing an opportunity to strengthen their relationship with your practice. Yet, they are tedious and can be difficult to place efficiently and predictably. An approach that addresses the most common challenges with Class II restorations can help you be successful.

Approach Class II cases with confidence. The Dentsply Sirona Class II Approach is the first and only complete approach to Class II restorations designed to increase efficiency and predictability for more consistent, successful clinical outcomes.

Class II Restorations complete procedure solution

Contact creation presenting a challenge?

For 70% of clinicians, contact creation is the most challenging part of a Class II restoration.1

You'll love our Palodent Family of Matrix Systems!

When using resin-based composite materials, both isolation and accurate contact creation are essential for successful Class II restorations. Palodent sectional and circumferential matrix systems are designed to help you get it right the first time, every time. The retaining ring, wedge, and sectional or circumferential matrix bands are designed to complement the tooth’s natural anatomy, working together to isolate, seal, and shape the restoration.

Radiographs inconclusive?

It can sometimes be difficult to determine whether a radiolucent area is caries or adhesive.

You'll love Prime&Bond universal Universal Dental Adhesive!

Thick adhesives can pool in the corners of the proximal box, leading to possible misdiagnosis as secondary decay on radiographs. Prime&Bond active offers a low film thickness, minimizing the risk of adhesive pooling and overtreatment without sacrificing the bond strength that is needed for successful restorations. And with almost no reported postoperative sensitivity, Prime&Bond universal helps to ensure patient satisfaction.

Uncertain of gap formation?

2 out of 3 dentists indicate cavity adaptation is the most important attribute for a successful restoration.2

You'll love SDR flow+ Bulk Fill Flowable!

SDR flow+ material is a one-of-a-kind breakthrough in dentistry—a bulk fill flowable that combines exclusive self-leveling properties and category-best shrinkage stress—which allows for placement up to 4 mm with excellent cavity adaptation, enabling the placement of gap-free restorations.

Too many Choices?

Dentists may spend as much as 14% of chair time selecting the appropriate composite shade.3

You’ll love Neo Spectra ST Universal Composite Restorative! 

A2 easily matches 80% of cases with a chameleon effect that's far more natural than single-shade universal composites.

Simplify shade matching by using the A2 shade for the final occlusal layer. Combined with preferred handling and a formula that does not stick to instruments, Neo Spectra ST with SphereTEC Filler Technology delivers the benefits that matter to dentists: optimized handling, enhanced chameleon blending ability, and improved durability, including stain resistance. For full VITA® shade coverage, choose from additional CLOUD shades A1, A3, A3.5, and A4.

Unsure if material at the floor of the proximal box is fully cured?

Many lights deliver less than 35% of their stated output to the floor of a proximal box.6

You’ll love SmartLite Pro Modular LED Curing Light!

Confidently cure even large restorations to the full depth and width of the restoration with 4 optimized LEDs that provide uniform light distribution over a full 10-mm diameter. A low profile design provides excellent access to posterior restorations, and combined with excellent beam collimation, the SmartLite Pro easily handles wide restorations and cures reliably even over larger distances.

Spending too much time finishing restorations?

Finishing and polishing represents 14% of total chair time for a Class II restoration. 7

You’ll love Enhance Finishing System!

The Enhance Finishing System accomplishes the entire process of excess removal, contouring, and finishing simply by varying the pressure. Push harder to remove excess composite; lessen the pressure for final results. The Enhance Finishing System delivers a smooth, contoured surface with a natural-looking finish in just 1 step.

Solutions for key challenges of class II restorations

Navigating key challenges of Class II Restorations

It may be difficult to achieve your goals due to challenges associated with Class II restorations. Predictably and efficiently manage Class ll restorations to keep patients happy and your practice profitable. Learn more!

Isolation

2/3 of doctors' experience difficulty achieving adequate isolation in a Class II restoration. 12

If the restorative field is contaminated with moisture, the physical properties and ultimate success of the composite restoration may be compromised.13

Learn more

Contact Creation

70% of clinicians find contact creation to be the most challenging part of a Class II restoration. 14

An open or improperly placed or shaped proximal contact can result in a fracture or food impaction, which can lead to periodontal inflammation, bone loss, and recurrent caries.15

Use Palodent Matrix System together with SDR flow+ material to alleviate the challenges of contact creation.

Sensitivity

Research shows that on average, 10-15% of posterior composite restorations result in postoperative sensitivity.5

The leading causes of postoperative sensitivity are:

  • Over-etching of the dentin8
  • Insufficient adhesive sealing of the dentin 9,10
  • Poor adaptation, leading to unfilled areas or voids 9,10
  • High shrinkage stress11
Learn more

Adaptation

2 out of 3 dentists indicate cavity adaptation is the most important attribute for a successful restoration. 16

High shrinkage stress may lead to marginal gap formation. Even if unfilled areas are avoided during placement, a gap-free restoration isn’t guaranteed if materials with high shrinkage stress are used.17,18

Use Prime&Bond active together with SDR flow+ material to alleviate the challenges of adaptation.

Shade Matching

Dentists spend as much as 14% of Class II chair time selecting the appropriate composite shade. 19

Closely matching the shade of a natural tooth can be challenging because of the time spent taking a shade and the inherent limitations of the human eye to accurately match color.20,21

Depth of Cure

Many lights deliver less than 35% of their stated output to the floor of the proximal box. 22

An insufficient cure can lead to adverse effects on physical properties, including:23

  • Reduced bond strengths
  • Breakdown at the margins
  • Microleakage
  • Secondary caries

Cure fully and reliably with confidence, including bulk filled restorations. Use SmartLite Pro curing light together with SDR flow+ material for faster, fully cured restorations that last.
