Orthodontics

How to permanently maintain achieved results after treatment of malocclusion – this is probably one of the greatest problem for orthodontists. Thanks to PDL´s memory orthodonticaly treated teeth tend to relapse to thein originál positions. Fixed retainers are the reliable solution to permanently maintain achieved results after treatment. Functionally reliable and highly esthetic alternative of fixed retainers offers Dentapreg™ Retainer.

DentapregTM Retainer Provides Several Important Advantages:

for permanent maintaining of achieved results of orthodontic treatment:
  • Simple procedure – no special tools nor adhesive systems required, fast two handed procedure
  • First class esthetics, subtle but strong devices
  • Outstanding biomechanical capability of retention thanks to glass fiber reinforcement
  • Metal free - no alergic
  • Patient friendly – non invasive, time saving, no need for long-term patient cooperation
  • Temporary to semi-permanent and permanent retentions
  • Good adhesion of the strip to the teeth and high stiffness of the strip provide appropriate rigid retainer structure which is necessary for stability of the retention.
  • Differentiation of retentions thanks to variability of shape and architecture of  Dentapreg™ strips
The shape, strenght and positioning of the retainer should reflect the strongest or most important predilection site for relapse. Dentapreg™ Retainer provides great freedom in choosing appropriate shape, architecture (strenght) and placing of the retention. Dentapreg™ Retainer serves as an high-tech but still easy to use tool for preparing retainers which exactly fit most individual postorthodontic situations.

Typical Situations for Clinical Use of DentapregTM Retainer in Orthodontics:

  • Closed Median Diastemas – short or long term retention, usually 4 unit retention
  • Multiple spacing of Anterior Teeth – difficult to retain, long term retention, strips with enhanced strength required
  • Periodontal Conditions with Tooth Migration – permanent retainer avoids jiggling forces and stabilize periodontally compromised teeth after orthodontic treatment in the new position
  • Accidental loss of Maxillary Incisor (childern – canines and premolars have not yet erupted)- when 2 stage orthodontic treatment is indicated, DentapregTM Retainer is bonded to the lingual surfaces of the approximated lateral incisors.
             Note: This approach can be chosen  in other two-stage operations.
  • Rotation of Maxillary Incisors – rotated incisors have a great tendency to relapse, DentapregTM Retainer is placed lingualy over six units and the situation may be treated with combination of removable plate or using advantage of excellent esthetic of Dentapreg™ Retainer there may be placed additional vestibular six units retainer.
  • 3 – 3 retention – retention bar
  • 21 – 12 retention – where there is uncertain optimal intercanine distance or there is need to settle canine undisturbed for other reason
  • Palatally Impacted Canines – display great relapse tendency in lingual direction, Dentapreg™ Retainer is bonded to the lingual or buccal of the teeth and it allows in this position undisturbed bone and soft tissue healing over long periods.
  • Space Maintainers – see Pediatric Dentistry
  • Semipermanent single tooth replacement – see Prosthodontics
  • Trauma fixation – see Traumatology

Positioning of Dentapreg™  Retainers:

  • Oral  – middle third of the crown, if a deep overbite situation remains, Dentapreg™ strips may be bonded gingival to the contact line
  • Vestibular – middle third of the crown
  • Occlusal – in the level of the interproximal contacts
