FAQs

Unica anterior
When should I use myCustom Resin with Unica anterior?

The use of myCustom Resin is recommended for fixing Unica anterior when it is not possible to adapt the matrix with interdental wedges. For example, in the case of a class III cavity adjacent to the cervical area of the tooth, the interdental wedge would risk deforming and/or moving the matrix (fig. 1). Therefore, the use of myCustom Resin is recommended in this case (fig.2).

myClip 2.0
How to autoclave myClip 2.0: in one piece or separately? Bagged or not?

According to the cleaning and sterilization guides, all detachable components of the devices must be disassembled. The tines must be removed from the ring.

Will myClip 2.0 loose the separation force after extensive usage?

No, tests have shown that the force of myClip 2.0 would not vary for at least 300 usage cycle.

How should I place the matrix?

The matrix should be “smiling”. It should be used with the extremities facing upwards. (Like the letter U).

Are the tines single-use?

No, they are autoclavable, sterilisable and interchangeable.

Do the tines break easily?

The tines have been developed not to break easily and resist multiple uses. However, the plastic material has a limited life cycle, which is why they can be replaced.

What material is your myClip 2.0 ring made of?

Stainless steel with surface colouring treatment.

Is myClip 2.0 made of plastic?

No, only the tines are made of plastic while the ring body is made of stainless steel with a surface colouring treatment.

Are your matrices disposable or re-usable?

Matrices are always single-use since they are shaped on a case by case basis. Moreover, in case of steel matrices, they can lose their shape during extraction.

Do the matrices have a non-stick treatment?

No, however thanks to the very high quality of the steel used to produce our matrices, the extremely smooth surface prevents the adhesion of composite / ionomer glass to the matrix.

What are the advantages of using a sectional matrix over a Tofflemire matrix band?

The curved and anatomical shape of the sectional matrices, in combination with the clamping action of the ring, allows for an optimal reproduction of the original proximal anatomy of the contact point.

myRing Forte
Is it possible to perform restorations of two adjacent cavities, mesial and distal at the same time?

Yes, the strength of the myRing Forte is sufficient for a proper teeth separation, allowing to compensate the thickness of two matrices – However in this case we recommend the use of ultrafine matrices with a thickness of only 0.025mm – Moreover, the design of the tines makes it possible to clamp the matrix in an optimal way both on the mesial and distal walls.

Can I refit the ring in case of deformation?

Should myRing Forte deforms due to incorrect use, it can be reconditioned using the special ring notches on the forceps myForceps.

Does it keep the separation force?

Yes, the double spring geometry of myRing Forte has been studied specifically to retain the separation force and avoid the deformation of the ring.

Can I perform MOD cavity restorations with myRing Forte?

Yes, you can use myRing Forte for MOD cavity restorations.  The geometry of the sectional system has been specially developed to allow the use of two rings at the same time.

How should I place the matrix?

The matrix should be “smiling”. It should be used with the extremities facing upwards. (Like the letter U).

How many times can the tines be used?

The tests show a resistance of the material of about 50 autoclave cycles. However, it depends on the way in which they are used.

Do the tines break easily?

The tines have been developed not to break easily and resist multiple uses. However, the plastic material has a limited life cycle, which is why they can be replaced.

What is the material of the tines?

Autoclavable thermoplastic polymer.

What is the myRing Forte made of?

Stainless steel.

Is myRing Forte made of plastic?

No, only the tines are made of plastic while the ring body is made of stainless steel with a surface colouring treatment.

Are your matrices disposable or re-usable?

myRing Classico
Can I refit myRing Classico in case of deformation?

The myRing Classico ring is made of Nickel Titanium. This material allows myRing Classico to feature an outstanding elastic memory. Therefore, it cannot be permanently deformed even in case of excessive opening and it will always return to its original shape.

Can I perform MOD cavity restorations with myRing Classico?

Yes, you can use myRing Classico for MOD cavity restorations.  The ring and the tines’ geometry has been specially developed to allow the use of two rings at the same time.

How to autoclave: in one piece or separately? Bagged or not?

According to the cleaning and sterilization guides, all detachable components of the devices must be disassembled. The tines must be removed from the ring.

How should I place the matrix?

The matrix should be “smiling”. It should be used with the extremities facing upwards. (Like the letter U)

What material is myRing Classico ring made of?

Nickel titanium with autoclavable thermoplastic over-moulding polymer.

Is your myRing Classico ring made of plastic?

No, the ring body is made of Nickel titanium with autoclavable thermoplastic over-moulding polymer.

myCustom Rings
Can I use other resins with the myCustom rings technique?

The use of other resins is not recommended as they do not guarantee an optimal result.  myCustom Resin features ideal thyxotropy, polymerization time, and final hardness for the use with myCustom Rings’ technique.

What is myCustom Rings technique?

The myCustom Rings technique is a method that allows to easily recreate the pre-existing interproximal anatomy. The ring tines are custom-shaped by taking an impression of the healthy and intact proximal walls using the included light curable myCustom Resin. This enables to achieve strong contact points and precise proximal contour during restoration.

myForceps
Can I use other forceps to position your rings?

myForceps was developed especially for Polydentia’s sectional matrix systems and its use with our rings is strongly recommended.  Other forceps cannot guarantee the right fit and strength to operate our rings.

LumiContrast
What is the purpose of dark colour?

The black colour develops better contrast between the cavity and matrix. This makes it easier to identify the operating area and the low reflection reduces eye fatigue, especially when using microscopes or loupes.

Can the coating of the Lumicontrast sectional matrices peel off?

No, as this is not a coating but a surface modification of the steel surface.

myWedge
Can I use 2 myWedges one stacked on top of the other?

Yes, the hollow geometry allows the use of two stacked myWedge for a better cervical adaptation of the matrix, if the clinical situation so requires.

What is the difference between myWedge and a wooden wedge?

myWedge is a plastic v-shape, compressible, hollow wegde which allows to gently adapt the matrix to the tooth and does not perform an orthodontic action. For this reason, myWedge should be used with myRing Forte since the separating action is already produced by the ring.
Instead, wooden wedges should be used with myRing Classico and myClip 2.0, as they provide the separation force needed to perform the restoration

myCustom Resin
what is myCustom Resin?

myCustom Resin is a light-curable, flowable resin similar to a common liquid dam (often used in bleaching procedures). myCustom Resin features ideal thyxotropy, polymerization time, and final hardness for the use with myCustom rings and Unica anterior.

Can I remove the myCustom Resin easily after the treatment?

Yes, myCustom resin is easily removable by hand or forceps.
