Restoring occlusal anatomy and achieving subtle shade integration were the aims of this clinical case by Dr Diana Villanueva: two direct restorations in molars 3.6 and 3.7 using Aster+ Kameleon, Kiyomi Dental’s new single-shade chameleon composite.
Restoring posterior teeth presents a challenge that goes beyond rebuilding lost tissue. Shape, colour and function must come together within a tooth structure that retains its own characteristics, including staining from previous restorations.
This case is one of the first clinical experiences shared with us by a clinician using Aster+ Kameleon. Its interest lies in observing how this new material blends into an everyday clinical situation: restoring molars with existing amalgam restorations and caries.
The clinical case: direct restoration of molars 3.6 and 3.7
Dr Diana Villanueva restored teeth 3.6 and 3.7, the lower left first and second molars, which presented with existing amalgam restorations and caries.
Treatment involved a direct restorative technique using Aster+ Kameleon from Kiyomi Dental, with three aims: to preserve as much tooth structure as possible, restore occlusal morphology and achieve natural aesthetic integration with the remaining tissues.
A particular feature of this case was the staining caused by the old amalgam. This adds interest to the assessment of the outcome: the composite needed to blend with a substrate that retained variations in colour.
Occlusal anatomy and shade integration: two aspects of the same outcome
According to the clinical description provided, the result shows well-defined occlusal anatomy and a subtle visual transition between the composite and the tooth structure, despite the pre-existing staining.
Anatomical reproduction and shade continuity both contribute to the appearance of the restoration. In this case, reconstruction of the occlusal surface aimed to respect the characteristics of the molars and restore their morphology.
The experience shared by Dr Villanueva illustrates the aesthetic outcome achieved in these two teeth. Clinical follow-up will allow their progress to be assessed; the available report focuses on the restorative outcome described.
What does the new Aster+ Kameleon offer?
Aster+ Kameleon is a light-cured, single-shade universal restorative composite with a chameleon effect. Its distinctive concept is designed to facilitate visual blending with a wide range of tooth shades and simplify shade selection.
This new material from Kiyomi Dental offers an approach involving fewer shade options where clinically indicated. Its formulation incorporates nanofiller technology, with SiO₂ and ZrO₂ nanoclusters ranging from 50 to 200 nm. This innovative filler optimises material performance, offering improved non-stick handling, excellent polishability and high mechanical strength. It is indicated for direct anterior and posterior restorations, including occlusal surfaces.
The appeal of its single-shade concept lies in combining simpler shade management with the aim of achieving a natural blend. Material selection still depends on the characteristics of the tooth, the substrate and the restorative needs of each case.
An early clinical experience with a single-shade composite in molars
Dr Diana Villanueva’s case brings the launch of Aster+ Kameleon into clinical practice. Beyond a technical description, it offers a specific application: two posterior restorations in teeth with existing amalgams, caries and residual staining.
Its contribution lies in demonstrating subtle shade integration alongside well-defined occlusal anatomy in the reported case. This early experience is of interest to clinicians wishing to understand how a single-shade composite could fit into their restorative procedures.
As this case illustrates, a posterior restoration should rebuild tooth structure, reproduce anatomy and aim for natural, functional integration.
