Why use DeltaFil?

Reliable restoration

Patented technology

Tailored colour range

Indicated at every stage of life

For effective treatment: Something for every patient

Everyday dental practice can be challenging:

Vulnerable patient groups such as the elderly and children present special challenges as they can be less cooperative.
High-risk patients who are particularly vulnerable to caries are a therapeutic challenge and require restoratives with a preventive effect.
With the EU banning amalgam, a suitable alternative needs to be found.
Tailored filling treatment must be affordable for all patients – regardless of their individual budget limits.

Reliable in any situation

DeltaFil can make your everyday dental practice flexible and reliable, and synonymous with high quality. Its special material properties enable satisfying treatment – even in patients that have special requirements. Unlike cost-intensive filling materials like composites, DeltaFil also offers financial advantages for patients.

Elastomeric micelle technology

Unique through innovation

When do conventional glass ionomer cements reach their limits?

When conventional glass ionomer cements (GICs) are subjected to high chewing pressure, crack initiation and crack propagation can occur within the GIC matrix.² The mechanical properties are limited, as fracture toughness and flexural strength are comparatively low.^3.4 Microfractures caused by repeated flexural and tensile stresses increase the risk of crack propagation within the cement matrix and damage in the cervical area.^5.6

DeltaFil: the unique and patented solution

Unlike conventional GICs, the elastomeric micelle technology (EMT) developed and patented by DMG makes DeltaFil an innovative filling material with unique improved mechanical properties that have been verified in a large number of preclinical studies.

High mechanical stability and increased resilience^7.8
Crack propagation minimised by micelles⁷
Chewing stability and abrasion resistance verified in preclinical tests⁹
Surface with very good initial and long-term stability – regardless of the finishing method used¹⁰

* The factors stated are based on the mean values for DeltaFil compared with the average values for standard glass ionomer filling materials in each test category. The comparison group is made up as follows: Fracture toughness: Fuji IX GP, Ketac Universal, Chemfil Rock (mean = 0.29 MPa*m^0.5). Flexural strength: Riva SC HV, EQUIA Forte HT, Ketac Universal (mean = 21.47 MPa) Abrasion: Ketac Universal, Fuji IX GP (mean = 13.47 mm³). The factors were calculated as ratios of mean DeltaFil value to mean competitor value. These comparisons are descriptive and not inferential statistical comparisons. Standard deviations were not taken into account in the calculation of the factor values.

The difference? Elastomeric micelles in the GIC matrix to minimise crack propagation

The micelles embedded in the material act like a shock absorber in the GIC matrix. They absorb tension, distribute it within the material and thus reduce local tension concentrations. This minimises crack propagation, which increases the material’s structural stability.⁷

Adapted range of shades

The extended range of shades was developed especially for deciduous teeth and teeth with age-related discolouration. The colour White is also ideal for bleached teeth.

Indicated at every stage of life

Good fillings feel good.

From the beginning: Suitable for deciduous teeth

For the treatment of carious deciduous teeth, glass ionomer cements like DeltaFil are particularly popular with patients and parents, especially under difficult treatment conditions.¹³ Your young patients benefit from DeltaFil’s broad spectrum of colours, including White, in the treatment of their deciduous teeth.

Support for vulnerable patients:
During and after tooth development

DeltaFil is suitable as a minimally invasive treatment method for the temporary restoration of “chalky teeth”, or molar-incisor hypomineralisation (MIH).

Treatment of adult teeth

Whether for patients with special requirements or those without any special risk factors, DeltaFil offers a flexible solution for patient-friendly permanent teeth treatment.

Targeted indications in advanced age: Treatment in advanced age

Those of advanced age often have limited oral hygiene – for reasons such as restricted movement or difficulties in accessing dental care. Furthermore, comorbidities and medication can often cause dryness in the mouth and reduce the buffering capacity of saliva.

This makes the ability of glass ionomer cements to release fluoride especially important. Elderly patients are also more likely to suffer from root caries and non-caries-related cervical lesions, and glass ionomer cements offer advantages in the restorative care of these conditions where limited patient cooperation and difficult isolation conditions are concerned and because of their cost-effectiveness.¹⁴

DeltaFil and chalky teeth (MIH)

MIH affects roughly one child in seven in Europe.¹⁵ This means that MIH is not an uncommon condition, and part of everyday dental practice. Hypersensitive porous molars and limited cooperation in children call for a treatment that is fast, gentle and reliable.

Enjoy the benefits of DeltaFil. The glass ionomer filling material for treating MIH

Moisture-tolerant and self-adhesive for hard-to-reach places
EMT reduces crack propagation and contributes to mechanical stability⁷
Fast, minimally invasive application without any complicated steps
Highly viscous consistency supports short treatment times
Fluoride release promotes remineralisation, particular relevant for increased caries risk because of MIH^1,16

Permanent indications:

Suitable for Class I, II* and V restorations and for the sandwich technique. Can also be used for extended fissure sealing, as a base/liner.

*Suitable for areas subject to occlusal load, provided the isthmus measures less than half of the intercuspal area.

Temporary indications:

Suitable for Class I, II, III and V temporary restorations and deciduous teeth. Offers flexible application options in various clinical scenarios.
