Reinforcement - Clinical Applications

Typical Indications

Dentapreg® SFU is a dependable, easy-to-use and esthetic option for tooth stabilization in periodontics, tooth stabilization in orthodontics, space maintanance and endodontics.

Stabilizing teeth with 
Dentapreg® SFU is required in the following situations:
- teeth become loose due to secondary occlusal trauma when normal occlusal forces are applied to periodontally compromised dentition (periodontics).
- healthy dentition tends to shift or relapse out of position (orthodontics)
- Stabilization of teeth with increasing mobility that have not responded well to occlusal adjustment and periodontal treatment.
- Stabilization of teeth with advanced mobility when there is interference with normal function and patient comfort.
- Facilitation treatment of extremely mobile teeth by splinting them prior to periodontal instrumentation and occlusal adjustment procedures.
- Prevention of tipping, drifting and supraeruption of unopposed teeth.
- Stabilization of teeth following orthodontic treatment when necessary.
- Creating adequate occlusal stability when replacing missing teeth.
- Splinting during a root amputation procedure when using the crown retained as a pontic is indicated.


Dentapreg® splint provides three-dimensional stabilization with simple application procedures. Dentapreg® splint is fixed to the tooth in a relatively large surface area. This fact, together with excellent adhesion between the fiber strip and the composite, provides appropriate rigidity of the connection of the splint to the tooth and does not allow the dentition to rotate or shift.

Specific clinical situations for use of Dentapregreg® SFU in periodontics include the following:
- Stabilization where tooth mobility is progressive with increased periodontal ligament widening and reduced bone height – adjunct to periodontal therapy.
- Permanent stabilization during regenerative stage of treatment adjunct to periodontal therapy.
- Permanent - palliative treatment (postponing of extraction).



Using Dentapreg® for post-orthodontic stabilization provides several important advantages for semi-permanent and permanent maintenance of achieved results of orthodontic treatment. Dentapreg® has outstanding biomechanical capability of retention thanks to glass fiber reinforcement and is non-invasive and patient friendly (no need for long-term patient cooperation as with conventional removable retainers). It also allows for the maintenance of proper oral hygiene.

Dentapreg® SFU can be successfully used as a post-orthodonitc retainer in the following situations:
- closed median diastemas
- periodontal conditions with tooth migration
- premature loss of maxillary incisor (children – canines and premolars have not yet erupted)
- rotation of maxillary incisors – rotated incisors have a great tendency to relapse
- 3 – 3 retention during and post treatment
- 21 – 12 retention – where there is uncertain optimal inter-canine distance or there is a need to leave the canine undisturbed for other reason
- palatally impacted canines – display great relapse tendency in lingual direction, correction of 2nd and 3rd molar - joint anchorage in mesial area of the denture (usually adult patients, pre-implant treatment).



Together with Dentapreg® PINPost, Dentapreg® SFU is a very useful product for a minimally invasive post-endodontic treatment. It can be used as a post to retain a crown after a root canal therapy. The advantage of Dentapreg® as compared to conventional pre-fabricated posts is that Dentapreg® adapts perfectly to the shape of the root canal and does not therefore require the dentist to enlarge the root canal to accomodate the post. 
Our recommendation is to use Dentapreg
® PINPost for smaller root canals and Dentapreg® SFU for larger root canals.

For more information on how to use Dentapreg® SFU for crown retention, please consult the instructions of use and look at the clinical examples.


Pediatric Dentistry

Dentapreg® SFU can be used to create a space maintainer as part of a therapy to maintain existing space once primary teeth have been lost prematurely.
