  • Product details

    Revolutionise your dental restorations with Dentapreg® UFM – ultra-thin glass fiber composite flexible and formable mesh, designed to reinforce and extend the life of composite work significantly.
    The fiber-reinforcement disperses occlusal forces mimicking the effect of dentinoenamel junction to prevent common fractures, ensuring better durability and longevity of your work.
    This innovative solution offers versatile applications, from crown reinforcement to incisal edge reconstruction, reducing the risk of fractures in high-failure scenarios and thus enhances your patient satisfaction.


    Dentapreg® is the perfect tool for biomimetic dentistry. For composite restoration to be successful there needs to be precise imitation of the original structure of the tooth. Two innovative products – Dentapreg® UFM and Dentapreg® PINPost – have been developed to do just that. The toughness of Dentapreg®’s unique fiber-glass, light-curing stretchable strip, allied with its ability to adapt perfectly to any shape of dental crown, make it indispensable for any minimally invasive dentistry toolkit. For restorations of all sizes and complexity, Dentapreg® is able to mimic the tooth’s dentinoenamel junction (DEJ) – as a result, occlusal forces are spread across the crown, thus preventing cracks and boosting the longevity of large restorations.  And when you need to reconstruct teeth following endodontic treatment or the fracturing of vital teeth, look no further than the Dentapreg® PINPost for fast, risk-free crown retention. 


    Rather than preparing a tooth for a crown restoration or fully extracting it, Dentapreg® can help to save a tooth quickly, without the need for complex techniques, materials or instruments. Dentapreg® UFM has the unique property of being able to mimic a tooth’s DEJ when placed in a restoration. This means greatly increased durability for your composite restoration work. These ultra thin, highly adaptable strips are made for minimally invasive dentistry – and for very noticeable clinical success stories.


    Dentapreg® UFM’s smart flexibility means that it’s suitable for a variety of different applications in restorative dentistry and minimally invasive prosthetics: crown build up and restoration, the strengthening of large restorations, the reinforcement of composite veneers and the reconstruction of incisal edges. Class IV restorations, such as for a chipped incisal edge, have by far the highest failure rate: they fracture all too often. To prevent the risk of a restored crown fracturing again, reach for an ultra thin glass fiber strip from Dentapreg®. This reinforcement will act as a biomimetic replacement of the DEJ by spreading the occlusal forces across the entire crown and preventing stress concentration in a single point, and thus: no fracturing. Not only can you trust Dentapreg® UFM to prevent restoration fractures, but it also delivers highly aesthetic results thanks to its overall malleability and ability to smoothly blend in with the colour of the surrounding composite.
  • Q&A

    General Dentapreg FAQ

    What does Dentapreg® look like?

    The strips and pins consist of specially surface treated glass fibers impregnated with high viscosity light-curable resin matrix. The fibers are in the form or unidirectionally oriented bundle or braided multidirectionally oriented flat tape. The dimensions vary depending on the indication range of a specific product. The strip is slightly sticky and can easily be formed and adapted into the desired position. The strip is placed under the non-transparent foil in protective films and sealed in a blister with aluminium foil.

    Why is Dentapreg® strip 6 cm long?

    Over the years, we have followed the recommendations from our customers and set a standard length of the pre-impregnated strips to 6 cm. This length is optimal for the needs of most applications and for minimizing the waste.

    What needs to be taken care of when handling Dentapreg® products?

    During manipulation, it is recommended to use powder-free latex or vinyl protective gloves and to use non-contact technique. Do not touch the unprotected strip with bare hands. Avoid using direct and intense light in the working area as this could lead to the loss of application properties. Do not use the product if it becomes contaminated or otherwise damaged while being placed.

    How to cut Dentapreg® strip or pin to the desired length?

    The strip can be cut using regular scissors. However, it is recommended to use clinical scissors. To avoid contamination, cut the strip when it is still placed in the protective films.

    What instruments can be used when forming and adapting Dentapreg® strips and pins?

    The strip can be formed and adapted in the desired position using standard instruments, such as tweezer, spatula, condenser and other composite filling instruments. Using of instruments with sharp edges should be avoided as they can damage the reinforcing fibers.

    Is it necessary to treat the surface of Dentapreg® products before use?

    There is no need for additional treatment of the strips or pins. The fibers are already impregnated by dental resin matrix to enssure strong and reliable adhesion.

    Which adhesive system can be used in combination with Dentapreg®?

    For optimal bonding, it is recommended to use a standard two-step etch-and-rinse protocol. Self-etching single step adhesive protocol is less desired and should be used in the case of short-term applications only.

    Which resin composite materials can be used in combination with Dentapreg®?

    Dentapreg® products are designed to be used in combination with any light or dual-curable resin composites  and cements available on the market today. The selection of a specific material depends on the given clinical situation and the dentist’s preferences.

    Must the entire surface of the strips or pins be covered with a covering composite layer?

    Strips and pins must be covered with a composite along the entire length. This is necessary in order to avoid irritation of soft oral tissues by exposed fibers and to protect the integrity of the framework structure. In the case of splinting, if there are no points of contact, build them from condensable resin composite.

    What are the storage conditions before opening the blister?

    Dentapreg® products should be stored at temperatures between 4 and 25 ºC (39 to 77  ºF) in an intact blister away from direct light sources. Do not expose to temperatures higher than 25 ºC (77  ºF) for extended periods of time. Do not use after the expiry date stated on the packaging.

    How long after opening the blister can Dentapreg® strips be used?

    After opening the blister, unused parts of the pliable strip in the protective films can be stored in the light protection box included in the packaging. In this packaging, store the product in a refrigerator at temperatures between 4 and 10 ºC, and use it within four weeks. If no contamination occurs, Dentapreg® pins can be stored without any restrictions in the original packaging for the entire shelf life.

    Does the original dimensions of Dentapreg® strips change upon forming?

    The strips with the multidirectionlly oriented fibers in the form of flat tape (Dentapreg® SFM and PFM)  are tightly interwoven and will not change the original dimensions upon forming. In the case of ultra-fine membrane (Dentapreg® UFM), the threads of fibers are loosely woven to provide flexibility and stretchability when adapted to a complex surface. The strips with unidirectionally oriented fibers (Dentapreg® SFU and PFU) allow for dimensional change of their cross-section due to limited flow of the impregnating resin matrix and corresponding movement of the individual fibers.

    What kind of curing light can be used to cure Dentapreg®?

    The type of curing light will not affect the properties of the final application, but affects the time necessary to cure the strip. Keep in mind that a successful application of splints, retainers or frameworks requires curing the strip along its entire length and hence multiple light exposure steps progressing from one side of the application to the other are required. When using standard LED curing light with power of around 700 mW/cm2, the curing step for one tooth is 40 s. When using a high-power curing light, the light-exposure time can be adjusted accordingly.

    Are there any contraindications and safety precautions to keep in mind during application of Dentapreg®?

    In very rare cases, the use of Dentapreg® medical devices may be associated with an allergic reaction. The use is contraindicated in patients with known over-sensitivity to any of the components contained (especially methacrylate monomers and polymers). During application, avoid contact with eyes, skin and soft tissues and ingestion. In the case of a contact of an uncured strip with soft tissues, gently wipe the affected area with a cotton swab or gauze, and rinse with water.

    Are there any special precautions to keep in mind after the application of Dentapreg®?

    Inform the patient of the necessity of following hygiene principles to preserve esthetics and reduce the risk of caries. Also, instruct the patient to see the dentist without delay in the event of functional failure.

    How to remove Dentapreg® application in case of need?

    The removal procedure is related to the specific type of application. The procedure of splint removal after it served its desired purpose has three steps. First, remove the covering layer of the composite by using a bur or using a polishing wheel to heat up the surface of the composite. The heated composite becomes soft and can be removed with a scaler. Next, remove the strip from the surface of the teeth. The easiest way is to use a scaler or orthodontic pliers and pull it from the interproximal spaces. Finally, clean and polish the teeth. The procedure of bridge removal has four steps. This includes cutting the retentions using a diamond bur, removing the pontic, removing the rest of the composite from the abutment teeth and finally, cleaning and polishing the abutment teeth.

    “Dentapreg fiber-reinforced composites have been an important part of my practice for over eleven years.  The SFM reinforced periodontal splints and PFM reinforced anterior bridges have given years of service.  In October 2023, I examined a periodontal splint from tooth #22 to tooth #27 which was placed in March 2013. The splint has never broken and the only maintenance was reattaching tooth #23 to the splint in November 2017.  An anterior bridge to replace tooth #23 was placed in July 2014 and is still performing well.”

  • Dr. Nikhil Bahuguna
    Director and Chief Dentist at Demystifying Smiles, Noida, India, with international dental qualifications and leadership roles.

    “Restorative dentistry, a name synonymous with BioMimetic Dentistry requires the use of materials and techniques mimicking nature. The use of stress reducing and dissipating materials like the Dentapeg® fiber reinforcement and the Fibrafill® range of flowable and bulk-fill dentin based composites has made a huge difference in the bio-mechanical outlook of doing restorations in my practice. The physical properties which match the natural flexure give stronger and longer lasting core restorations and the minimally invasive radicular reinforcement protecting against cracks and fractures of the tooth-restoration complex  is the biggest asset in saving the teeth for long term success. The unique, pre-impregnated, flexible glass fiber technology is a boon, helping us dentists save, restore and rehabilitate human dentition with predictability and enables us to provide clinical longevity with ease.”
