Our case reports

Class II with Estelite Asteria

Dr. Andrea Fabianelli

” A young patient comes to our office for a routine check-up. The clinical examination and transillumination disclose discoloured distal areas on teeth 14 and 15. The subsequent x-ray examination reveals two distal carious lesions on such teeth. After placement of the rubber dam,  careful excavation of the infected tissues and application of an enamel-dentin bonding agent, sectional matrixes are applied and we start restoring the teeth with a first 0.5 mm layer of fluid composite (Estelite Flow Quick High Flow). Afterwards, the interproximal wall is reconstructed using Estelite Asteria WE enamel and the residual cavity is restored with horizontal layers of Estelite Asteria body shade A3B. The last occlusal half millimetre is reconstructed using Estelite Asteria NE and WE enamels and stains are applied to simulate sulcus pigmentations. The restoration is polished and the dam is removed.
The characteristics of the Asteria composite make polishing fast and glossy, with excellent esthetic and mimetic results. ”

Fig. 1:

The clinical examination shows two distal discoloured areas of teeth number 14 and 15 and the x-ray confirms that they are two D2 carious lesions in Lutz’s classification

Fig. 2:

The lateral view hints at a more extensive carious lesion on tooth 15

Fig. 3:

The dam is applied

Fig. 4:

Access to the carious lesions is gained first occlusally and adjacent teeth are protected with metal matrix pieces while the residual interproximal walls are removed

Fig. 5:

The infected, softened dentin is removed using zirconia round burs, at low-speed and air jet cooling

Fig. 6:

The infected dentin has been completely removed, residual tissues are checked with a handheld excavator and they are hard

Fig. 7:

The undermined enamel is removed with red ring burs on a multiplier contra-angle handpiece

Fig. 8:

Interproximal margins and the cervical step are finished with diamond tips mounted onto a subsonic instrument

Fig. 9:

Cavities are finally prepared and ready to be restored

Fig. 10:

Liquid dam is applied on a small gap close to the clamp to ensure isolation during adhesion and restoration

Fig. 11:

Sectional matrixes are placed with separating rings and wedges

Fig. 12:

The selected bonding agent is applied following the producer's instructions

Fig. 13:

The bonding agent is cured with a high power light

Fig. 14:

A first, thin layer of flowable composite (Estelite Flow Quick High Flow) is applied to reduce marginal infiltration and improve the adjustment of the restoration material itself to the cervical step

Fig. 15:

Interproximal walls are sculpted with Estelite Asteria WE enamel, transforming a class II into a class I. The worsening of the cavity factor is compensated for by the flexibility of the wall itself, which is very thin

Fig. 16:

Restorations are completed by layering with dentin masses (Estelite Asteria, Body shade A3B) and with occlusal enamels (Estelite Asteria, Enamel shades: NE and WE)

Fig. 17:

Restorations are polished with abrasive discs, silicone cups and tips

Fig. 18:

Lateral view of the restoration

Fig. 19:

Restorations are glossed with felt wheels and polishing pastes
