Finishing and Retention Orthodontic Appliances
Flat Labial Bow
Retainer with flat labial bow soldered
to Adams Clasp
Flat Labial Bow
with Extensions on the Cuspids
Retainer with flat labial bow and the flat wire is carried back to the distal of the cuspids adding retention to stabilize the cuspids after movement.
The Ricketts retainer crosses through the embrasures interproximally to the laterals and cuspids. The loops are placed on the laterals and the distal arms are contoured to the cuspids.
The distal arms can be used to increase retention as well as help stabilize cuspids.
Adams Soldered Round Bow
Retainer with round labial bow soldered to Adams Clasp. Optional incline plane and second molar springs to move teeth lingual.
Circumferential (Wrap Around)
With a flat labial bow. Embrasure clasps added to the lingual of the six year molars for better retention.
Circumferential (Wrap Around) with Crozat Clasp
With flat labial bow and optional Crozat Clasps or Ballzat Clasps. On buccal of the six year molars.
Maximizes retention when second molars are erupting.
Retainer with Labial Bow
Distal to Cuspids
With Soldered C-Clasps on Bicuspids. Optional embrasure clasps lingual of the six year molars.
(Wrap Around) Appliance
The Tremont appliance for maxillary retention is designed without support wires. Contoured around the second molars, the labial bow can be positioned up or down by adjusting the cantilever arm with a three prong plier. The cantilever arm is parallel to the labial bow and provides stability without coming in contact with the tissue.
Apron Spring Labial Arch
This appliance has an active labial arch wire that is primarily used to retract severely flared anteriors.
It features two helical coil springs for continuous lingual movement and is easily activated with pliers or finger pressure.
The Double Retainer is a maxillary and mandibular appliance that is used as an Anterior-Posterior retaining device.
This is particularly used in patients who have undergone treatment with Herbst appliances, Twin Blocks and other
Functional Orthopedics. Another reason The Double Retainer is popular is that in adult therapy it is a great appliance to
wear as a night time retainer. Whether the patient has been treated for TMJ or orthopedically corrected surgically or
non-surgically, the Double Retainer will hold the mandible forward throughout sleep.
Double Retainer Fabrication Requirements:
1. Upper and lower models with a wax bite registration.
2. Bite should be in an edge-to-edge incisal relationship with a 1-2 mm anterior vertical opening.
Used to stabilize mobile upper and lower anterior teeth. This appliance is constructed using bondable mesh pads connected by wire. The appliance is adapted to the lingual surface of the teeth.
Phase I Retainer
.028 Bonded Retainer
with transfer tray
.032 Twisted Wire
Bonded Retainer with custom contoured bonding pads
Bonded Retainers offer the advantages of being inconspicuous and hygienic. This appliance is bonded to the lingual of the cuspids with custom contoured, direct bond pads. Additionally, many choose to use .032 twisted wire or .028 wire bonded to cuspids. The laboratory fabricated transfer tray makes correct placement of the wire easy with minimum chair time.
A popular retainer design for the appearance conscious patient. Improvements in materials have led to Invisible
Retainers lasting longer. They can be used to align teeth with no more than 1 mm of movement per tooth. A number of invisible retainers can be fabricated with a series of setups to achieve greater tooth movement. It is recommended to use a Poly Vinyl Siloxane material impression to maintain model accuracy due to multiple pours.
The Essix Invisible Retainer is a cuspid to cuspid version of the standard full arch appliance. Minor tooth movement is possible with this appliance design.
A common style of bleaching tray is similar in construction to an athletic mouth guard. Initial indications are that a foam lined tray is more effective than a simple niteguard, tray, splint, or mouth guard. The Foam holds more of the active material next to the tooth's surface thus deceasing bleaching time by 20% to 30%.
Finishing & Retention Fabrication Requirements:
When sending a removable appliance to the laboratory, both upper and lower models are requested to avoid occlusal interferences.
