Clinical Use of Dentapreg™ SFM or SFU in Periodontics

• Temporary stabilisation before final solution – adjunct to periodontal therapy
• Stabilisation where tooth mobility is progressive with increased periodontal ligament width and reduced bone height – part of periodontal therapy
• Long-term stabilisation during regenerative stage of treatment – part of periodontal therapy
• Long-term stabilisation - palliative treatment (postponing the extraction)

Positioning of Dentapreg™ SFM or SFU

• Oral – middle third of the crown
• Vestibular – middle third of the crown
• Occlusal – on the level of the interproximal contacts

Clinical Use of Dentapreg™ SFM or SFU in Traumatology

Splinting is a required treatment in the case of following dental injuries (according to WHO System modified by Andreasen and Andreasen):

·         Injuries to the Hard Dental Tissues and the Pulp

Crown-root fracture (suggested splinting time: 3 months)
The emergency treatment objective is to stabilize the coronal fragment in its anatomically correct position to adjacent teeth with a splint to optimize healing of the PDL while maintaining esthetic and functional integrity. Further treatment depends on comlexity of the injury.

Root fracture (suggested splinting time: 3 months)

Treatment objectives: to reposition and stabilize the coronal fragment in its anatomically correct position to adjacent teeth with a splint to optimize healing of the PDL while maintaining esthetic and functional integrity

·         Injuries to Periodontal Tissues

Subluxation (loosening) (suggested splinting time: 7-10 days)

Treatment objectives: to optimize healing of the PDL by stabilizing loosen tooth to adjacent teeth with a splint.

Lateral luxation isolated (suggested splinting time: 2-3 weeks)

Lateral luxation Alveolar fx (suggested splinting time: 6-8 weeks)

Treatment objectives: to reposition and stabilize the coronal fragment in its anatomically correct position to adjacent teeth with a splint to optimize healing of the PDL while maintaining esthetic and functional integrity.

Extrusive luxation (suggested splinting time: 2-3 weeks)

Treatment objectives: to reposition and stabilize the coronal fragment in its anatomically correct position to adjacent teeth with a splint to optimize healing of the PDL while maintaining esthetic and functional integrity.

Intrusive luxation (suggested splinting time: 2-3 weeks)

Treatment objectives : to reposition and stabilize the coronal fragment in its anatomically correct position to adjacent teeth with a splint to optimize healing of the PDL while maintaining esthetic and functional integrity.

Avulsion (suggested splinting time 1-2 weeks)

Treatment objectives: to replant and then stabilize the replanted tooth in its anatomically correct position to adjacent teeth with a splint to optimize healing of the PDL while maintaining esthetic and functional integrity.

·         Injuries to the Supporting Bone

Fracture of the alveolar process (suggested splinting time: 6-8 weeks)

Treatment objectives: repositioning of the fragment and stabilizing it to adjacent teeth with a splint.

Fracture of the mandible (suggested splinting time: 6-8 weeks)

Treatment objectives: immobilization of mandibular fractures. There are two options for splinting:

1. splinting in the mandible (simple fracture of mandible body or alveolar process, patient cooperation necessary!)
2. maxillomandibular fixation - closed reduction

Note: Suggested splinting time means minimum time for splinting. Real splinting time should reflect the healing process of the individual clinical situation.

Positioning of Dentapreg™ SFM or SFU

• Vestibular – as close as possible to the middle third of the crown
• Vestibular and oral – for splinting teeth in mandible (immobilization of mandibular fracture)

 Clinical use of Dentapreg™ SFM or SFU 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 stabilizes periodontally compromised teeth after orthodontic treatment in the new position
• Accidental loss of Maxillary Incisor (children – canines and premolars have not yet erupted) - when 2 stage orthodontic treatment is indicated, Dentapreg™ SFM or SFU 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, Dentapreg^TM SFM or SFU  is placed lingually over six units and the situation may be treated with combination of removable plate or, by using the advantage of excellent esthetic of Dentapreg™ SFM or SFU, there may be placed additional vestibular six units retainer.

• 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™ SFM or SFU is bonded to the lingual or buccal part of the teeth and  in this position it allows undisturbed bone and soft tissue healing over long periods.

• Semipermanent single tooth replacement – see Prosthodontics
• Trauma fixation – see Traumatology

Positioning of Dentapreg™ SFM or SFU

• 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 – on the level of the interproximal contacts
