C-tube And C-palatal Plates

Screws | Plates

C-tube and C-palatal plates are included in the OrthoAnchor System for situations in which anchorage screws cannot be applied. These include:

  • Lack of space between tooth roots. Plates can be placed away from tooth roots and "reach" down with orthodontic attachment.
  • Monocortical depth fixation (4-5mm screws can be used).
  • Situations in which screws do not provide adequate fixation or force vector. Plates also have multiple points of anchorage (micro screws) in the bone and form an independent, stable structure.

The easily adaptable plates are placed directly on the bone, requiring a small soft-tissue flap and periosteal elevation. Drill-Free® 1.5mm micro screws are used to fixate the plate to the bone. The C-tube portion of the plate is brought through the soft tissue, and the incision is closed around the plate shaft. The tube has an inner diameter of 0.9mm (.035"), accepting an archwire, ligature wire or other orthodontic hardware. A spring can be placed onto the archwire distal to the tube during retraction

The use of implant-quality titanium micro plates and screws provides both perfect bio-compatibility and ideal resistance with respect to bending or adaptation.

Indications:
  • Present posterior occlusal relationship should be maintained stably.
  • The occurrence of periodontitis and dental caries should be prevented.
  • There is no dental anchorage.
  • Posterior teeth cannot be used as a dental anchorage due to excessive alveolar bone loss.
  • The use of skeletal anchorage can shorten treatment period.
  • When maximum anchorage preparation is required.
  • When skeletal anchorage is required but the width of attached gingiva is insufficient.
Contra-indications:
  • When cortical bone is not thick enough.
  • When the patient has abnormal habit of mastication for retention and stability after implantation.
  • It cannot be used in deciduous or mixed dentition.
  • Active infection.
  • Patient conditions including blood-supply limitations, insufficient quantity or quality of bone, or latent infections.
  • Patients with mental or neurological conditions who are unwilling or incapable of following post-operative care instructions.
  • Foreign-body sensitivity; where material sensitivity is suspected, tests are to be made prior to implantation.
