Fractures? Chippings? Repairs with iBond Universal.
Repairs help preserve sound tooth structure and prove to be a safe and effective procedure that can save time and money with relatively minor effort. iBond Universal is ideal for intraoral repairs.
Why is iBond Universal so ideal for intraoral repairs?
- Preserve sound tooth tissue
- Just one bottle for most materials
- No need to apply hazardous hydrofluoric acid
- Minimally-invasive and cost-effective solution
The intelligent formula of iBOND Universal contains MDP and provides instant and reliable bond strength. Scientists from Europe and Japan have cooperated in order to equip our clients with a bonding that combines the best of two worlds. The different components interact to allow effective etching, good penetration into the dentinal tubules, durable and consistent bond strength as well as optimal bonding to ceramic, metal and tooth surface.
Why are repairs preferable to replacements?
Localised restoration defects, such as fractures and chippings, often still result in the replacement of the total restoration. Yet, recent clinical studies show that repairs are a state-of-the-art treatment of localised restoration defects.
They help preserve sound tooth tissue and prolong the restoration lifecycle, as every replacement destroys more sound tooth structure.

FAQs about intraoral repairs with iBond Universal...
When can I repair and when should I make a replacement?
A recently published review article from the University of Munich has defined 4 treatment options for defective restorations:
1. Monitoring of restorations in case of minor shortcomings as restoration discolouration or small marginal imperfections which do not bear disadvantages for the patient if left untreated.
2. Refurbishment of a restoration if the shortcoming can be adjusted without the need of adding new restoration material. Examples are removal of overhangs, polishing of discoloured margins, sealing of small voids or pores.
3. A repair is indicated if the restoration has localised shortcomings which require the addition of restorative material. A repair needs to be done, if the imperfections would lead to a deterioration if left untreated. Examples are localised caries adjacent to the filling margins, fractures of the restoration material or the surrounding tooth, marginal gaps.
4. A replacement is indicated if the restoration shows generalised or serious issues which require a treatment. Also, if the defect cannot be accessed completely or is not reasonable, a replacement of the restoration should be done. Examples for necessary replacements are massive caries or a variety of shortcomings on one tooth. 2

Which surfaces can be bonded with iBond Universal?
iBOND Universal can bond to the following surfaces: zirconia, precious and non‐precious alloys as well as composites/compomers. To bond and repair silicate ceramics, apply iBOND Ceramic Primer before to the fractured ceramic surface.
What pre‐treatment is necessary to the preparation, and/or tooth, when repairing a restoration?
Roughen the surface of the substrate to be repaired using a diamond bur or sandblasting. Rinse thoroughly and dry with an oil‐free air flow. In case of silicate and glass ceramics, the restoration surface needs to be pre‐treated with iBOND Ceramic Primer.
Follow this by applying iBOND Universal in a gentle rubbing motion for 20s, air‐dry and light cure for 10s prior to application of the composite.
What is the benefit of using the iBOND Universal system for intraoral repairs of silicate (glass) ceramics?
When placing indirect restorations made of silicate ceramic, the ceramic surface needs to be etched using hydrofluoric acid followed by the application of a silane as iBOND Ceramic Primer. The extraoral usage of hydrofluoric acid to etch the ceramics is safe. But contrary to that, the intraoral usage of hydrofluoric acid contains the risk of severe necrosis of mucosal tissue or even bone necrosis. When using hydrofluoric acid during an intraoral repair on silicate ceramics, tight fitting rubber dam needs to be applied and the acid needs to be handled with extra care. Thanks to the iBOND Universal system, this risk can be avoided because for intraoral repairs of silicate ceramic the hazardous usage of hydrofluoric acid is not needed. The usage of iBOND Ceramic Primer followed by the application of iBOND Universal on the ceramic surface is sufficient.
For which material does iBOND Universal require a primer (silane)?
iBOND Universal requires iBOND Ceramic Primer on silicate/glass ceramics.
Why is a primer (silane) for silicate/glass ceramic required?
For the bonding to silicate ceramics the ceramic surface needs to be pre-conditioned always using an additional silane. Therefore, iBOND Ceramic Primer needs to be applied on the fractured ceramic surface prior to the application of iBOND Universal. An independent study from the University of Erlangen has shown that it is always recommended when using universal adhesives to silanise silicate ceramic surfaces using an extra silane to obtain higher bond strength. 1

What happens if the iBOND Ceramic Primer comes accidentally in contact with the tooth surface?
Do not apply iBOND Ceramic Primer on enamel or dentine as it reduces bond strength to the tooth. Use a thin brush (for example our green applicator tip) for applying it on the restoration in narrow cavities. If accidently the tooth surface is contaminated by iBOND Ceramic Primer rinse it off with water-air stream before starting the bonding procedure as written in the instruction for use.
Can I buy the iBOND Ceramic Primer separately?
Yes, iBOND Ceramic Primer (1x4ml) is available as a refill: (article code: 66061416)
In which repair situations can I use a phosphoric acid etchant prior to iBOND Universal?
Some dental practitioner clean restoration surfaces using phosphoric acid etchants prior to repair. This can be done as long as the fractured surface is made of silicate/glass ceramic or composite. If the surface to be repaired is metal or zirconia, the surface must never be touched by phosphoric acid. The bonding to metal and zirconia surfaces is done by the phosphoric groups of the MDP-monomer which is also an ingredient of iBOND Universal. If the metal or zirconia surface came previously in contact with phosphoric acid, the metal or zirconia surface is covered already by phosphate which makes it impossible for the phosphoric groups of the MDP-monomer to bond to the metal and zirconia surface.
