I find the consistency of inspiro very firm; is this normal?
The high viscosity of the product results mainly from its technology with a homogeneous dispersion of the nanoparticles which produces a thickening effect of the composite; this property is initially surprising for some practitioners, especially those who use low viscosity products. In fact, this firm consistency turns out to be a "plus" for modelling a composite, ensuring its shape stability before photopolymerization. This composition of inspiro also gives in return excellent mechanical properties and surface finish.
Our tip: Use a composite warmer (for example: ADDENT)
I find the consistency of inspiro a little dry at the beginning of its application; is this normal?
The sensation that inspiro is a little "dry" can occur at room temperature, especially when using the first portion of composite extracted from a syringe or a compule.
Our advice: place the product in the mouth and after a few seconds of handling, you will appreciate that the increase in temperature (about 32° C in the oral cavity) will provide a much better plasticity through the thixotropic behaviour of inspiro.
Can I heat inspiro?
It is quite possible to use one of the many devices available on the market to heat inspiro and make it softer when it is placed in a cavity or on the tooth. This is a popular way of working, although the use of a heated composite is a personal choice and is not imperative. Be careful, however, of a possible increase in chemical reactivity of the material with a slight reduction in working time (as it is the case with any composite material).
Should I expect a loss in luster for fillings made with inspiro, as it happens with some other nano-hybrid composites?
The "classic" nano-hybrid composites have an inhomogeneous structure containing clusters and prepolymers of nanoparticles, while inspiro is a new type of homogeneous nano-hybrid composite without mini or macro clusters and prepolymers, which are common in old nano-hybrid materials. The surface features of inspiro are therefore significantly improved both in terms of polishing and luster stability.
Is inspiro very sensitive to light and does it allow enough working time?
In order to guarantee a good polymerization and storage time, it is necessary to have a good (= just quantity) of photoinitiator and it is not possible to work the product under the operating light at full power, especially with LEDs which contain more light in wavelengths close to blue compared to the old halogen lamps. The working time of inspiro is nevertheless among the best in its category.
Our advice: It is necessary to decrease the intensity of your operatory lamp and to move it away from the operative field, by directing the flow of light with the lowest possible angle (grazing light) on the working area; thus, the light is reflected on the shiny surface of the composite instead of penetrating deeply.
keyboard_arrow_rightPhysicochemical properties of inspiro
Does inspiro contain and release BPA (B-phenol A)?
Only materials containing Bis-DMA are capable of releasing Bis-Phenol A (BPA) under the physiological and biochemical conditions of the oral cavity; inspiro does not contain any Bis-DMA. The inspiro matrix contains Bis-GMA, a monomer containing two BPA nuclei in its center; however, the release of these BPA molecules is impossible chemically or mechanically (i.e. by wear) and inspiro must be considered "non-BPA releasing" (without release of BPA) as long as it is properly cured, as more than 90% of the composites currently on the market. However, it is crucial to apply a "BPA free" protocol that consists of polymerizing the composite completely and under glycerine gel before removing the isolation (rubber dam or cotton rolls). Finally, it is important to know that the doses possibly released from composites materials are considerably lower than those needed to obtain a biological effect, toxic or hormonal, in the unlikely event that the composite would not have been correctly polymerized and manipulated. Unfortunately, we are in an environment heavily polluted by BPA, found in air, soil, dust and water, and sources of non-dental contamination account for 99.999% of present risk (see below).
What is the composition of inspiro?
The filler amount
The filler loading of the product is 83% (Weight) and 65% (Volume) for the restorative masses of and 65,5% (W) and 38% (V) for the flowable masses. Filler loading is a good (but not the only) indicator of the mechanical performance and shrinkage rate of the product. The filler volume is seldom used and therefore does not allow comparisons between products.
The Barium Glass in the filler
It is softer (i.e. compared to Strontium glass) and has better surface qualities for aesthetic restorative material (luster) as well as good wear resistance as it is easier to silanize (essential for the cohesion between the load and the matrix).
The matrix of inspiro
The matrix is based on BIS-GMA. Bis-GMA has a very low water absorption (that does not cause any loss of mechanical performance) but is very useful for relaxation of polymerization stresses. Reinforcement by homogeneously distributed nanoparticles in the matrix provides better mechanical performance and helps to reduce the contraction of polymerization compared to a conventional micro-hybrid material.
The material has a volumetric contraction rate of 1.8%, being similar to conventional nano-hybrids but has much better mechanical and surface characteristics than the previous composite generation with an inhomogeneous structure. In comparison, bulk-fill materials have a contraction rate of 1%
keyboard_arrow_rightOptical properties and tint concept of inspiro
What are the optical properties of inspiro?
The hue concept of the inspiro system
The inspiro system is the latest development among composite systems based on the Natural Layering Concept, developed by Dr. Didier DIETSCHI. This simple but extremely powerful concept is based on the application of two basic layers (dentin and enamel) whose optical characteristics are ideally mimicking natural dental tissues. Five Effect shades complete this system to reproduce the polychromatic appearance of certain teeth.
Body (dentine) and Skin (enamel) tints
All masses "body" have the same color ("hue") and are declined in 8 levels of saturation (chromatic density), from Bi0 to Bi7. It must therefore be remembered that color and saturation are two different optical dimensions. The skin enamel masses have all the variations of hue and translucency to faithfully reproduce natural enamel variations.
The refractive index of inspiro
The refractive index of inspiro has not been measured since many scientific studies have shown that all composites have a refractive index of between 1.55 and 1.57, which is identical to dentin (IR = 1.52) and very close to enamel (IR = 1.63); the average difference between composite and natural enamel is then only 3 to 4%! Moreover, no study has confirmed a possible influence of this property on aesthetic integration. Other optical properties such as translucency/opacity, brightness, color and opalescence, however, have a proven importance on aesthetic integration.
What are the conditions influencing the optical transition at the margin of a restoration?
The determining factors for a smooth optical transition at the margins of a restoration are:
- type of finish (bevel, hard edge, chamfer, etc ...)
- the configuration of the cavity and tissue thickness at the margin (the most important)
- the thickness and opacity of the adhesive
- the optical properties of the composite
Our advice: We recommend the preparation of a medium extent chamfer, with a slight dentine shoulder when possible to avoid a shadow in the marginal area.
How does the inspiro shade guide work?
The choice of dentine chroma is made by comparison and selection of the adequate dentin shade sample in the cervical third where there is a thin enamel layer. The choice of the enamel color is done directly in superposition on the dentine sample previously selected. It is normal for cervical chroma to appear slightly weaker in the cervical area when both samples (dentin and enamel) are superimposed. In comparison with the VITA ™ shade samples, the durability requirements of the composite shade guide mean that the side areas are thicker than the natural enamel, reducing slightly the perceived chroma as compared to the VITA ceramic system samples. Knowing that it is necessary to place the incisal edge of the shade guide against that of the tooth (rather than side by side), this small difference in chroma does not interfere with the precision of the choice of color.
What is the difference between the MIRIS 2™ (Coltenewhaledent) shade guide and the INSPIRO® shade guide?
The function of both shade guides is 100% similar (with glycerin between the two parts) but it is crucial to know that, being particularly the enamel colors of inspiro very different from Miris2, we cannot use mix and match the shades of one of the products for the other!
Is there a correspondence between the inspiro shade guide and the VITA Classic™ one?
The inspiro-VITA ™ correspondence table presented in our catalogue and on the website is not intended to suggest the use of the VITA shade guide for the selection of inspiro colors in the mouth. This table is simply a didactic aid to understand the NLC system and its relation with the VITA system.
In which material is the inspiro shade guide manufactured with?
The inspiro shade guide samples are made from the same composite material as found in the inspiro syringes and compules, unlike the vast majority of other products.
How to clean and disinfect the inspiro shade guide?
The samples can be disinfected cold with an alcoholic solution (wipes and sprays ...) or with a product based on chlorhexidine. However, we do not recommend immersion of the shade guide in these solutions for a prolonged period (30s or more), as this may cause deposits or alteration of the shade samples surface.
