Abstract

Dental caries involving proximal surface of the anterior teeth can present both esthetic and restorative challenges, especially if right in the midline. A restorative material which can flow, and can be manipulated as well, can serve as an apt material in such cases. Activa Pronto is one such novel material which can be used for esthetic restorations with additional bioactive property, as it releases and recharges calcium, phosphate and fluoride, and is indicated for all classes of cavities. This case report describes one such case of restoring Class 3 dental caries with Activa Pronto.

Introduction

Placement of physiologically contoured, esthetic Class III composite restorations can be a deceivingly difficult procedure. These types of lesions may present with limited clinical access, making traditional composites tough to place without creating marginal voids. Although flowable composites are better suited for this task due to their ease of placement, their use becomes limited when the depth of the preparation is greater than 2 mm from the facial to the lingual aspects. 1 Many flowable composites are being widely used recently with wide range of applications.
Activa Pronto is a universal, stackable and shapeable, light cure composite that is strong, durable, wear and fracture resistant, releases and recharges calcium, phosphate and fluoride, and is indicated for all classes of cavities. It is described asthe first light cure composite designed to mimic the properties of natural teeth.2This material has a depth of light cure upto 2.6mm and 70% filler by weight.
This case report describes the restoration of class 3 carious lesion using this novel bioactive material with the aim of achieving optimal esthetic outcome and create a restoration that mimics the natural teeth.

Case Narrative

A 22 year old female presented to clinic complaining of decayed upper front tooth. On examination, class 3 carious lesion was noted on 11 and 21. Minor anterior crowding was also noted. (Fig:1 A-C)

Etching was done using total-etch technique followed by bonding agent, after which matrix band was applied and mesial shelf was created using Activa Pronto A2 shade (Fig 3 A-C)

Patient Perspective

Patient’s main concern was the esthetic problem caused by the carious lesion. Optimal aesthetics and function were successfully restored to patient satisfaction.

Conclusion

For many years, it has been a goal to develop composite restorative materials that facilitate a more simplified, less technique-laden approach to clinical placement. The additional benefit of bioactivity of the material can be advantageous to the patient as well as the clinician in providing long lasting esthetic restorations. This, combined with its high polishability and shade-matching ability, makes Activa Pronto a high-quality restorative option for a variety of clinical applications.

Planning a Class III restoration in a rotated tooth

Rotation changes access, contact position, emergence profile and the apparent distribution of light. The restoration must therefore reproduce not only colour but also contour and cleansability. Isolation, conservative caries removal, matrix stabilisation and a planned finishing sequence are central to the result.

ChallengeClinical objectivePractical control
Restricted proximal accessPreserve sound enamelSelect the least destructive access consistent with caries removal
Midline contactCreate a cleansable contact and embrasureStabilise an anatomically adapted transparent matrix
Shade mismatchReproduce value, chroma and translucencyChoose shade before dehydration and verify with cured samples
Visible transitionBlend restoration and enamelUse controlled contouring, finishing and polishing

For a detailed colour workflow, continue with composite shade selection. For indirect alternatives, compare inlay and onlay impression principles. Broader restorative planning is covered in crowns and bridges clinical tips.

Frequently asked questions

When should shade be selected?

Before prolonged isolation dehydrates and lightens the tooth, under neutral and consistent lighting.

Why is matrix adaptation critical?

It influences contact, cervical seal, contour, finishing access and periodontal cleansability.

Should every Class III preparation receive a bevel?

No. Bevel design depends on margin location, remaining enamel, occlusion and restorative objectives.
