Finishing and Retention Orthodontic Appliances

Flat Labial Bow

FRT08

 

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.

Ricketts Retainer

FRT23

 

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)

FRT06

 

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

FRT17

 

With Soldered C-Clasps on Bicuspids. Optional embrasure clasps lingual of the six year molars.

Tremont Cantilever

Circumferential

(Wrap Around) Appliance

FRT18

 

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

FRT21

 

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.

Double Retainer

FRT22

 

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.

Krause Retainer

FRT20

 

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

FRT13

.032 Twisted Wire

Bonded Retainer

FRT12

Bonded Retainer with custom contoured bonding pads

FRT14

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.

Invisable Retainer

FRT11

 

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.

EssixTM Retainer

FRT19

 

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.

Bleaching Tray

FRT26

 

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.

 

Acrylic Features

  • Anterior Bite Plate used to open the bite and disclude posterior teeth.

  • Posterior Bite Plate used to open the bite. Opposing arch should be included with any case where occlusal acrylic is added to the appliance.

  • Upper Incline Bite Plate used to reposition the mandible forward.

  • Acrylic Bow that tightly conforms to the labial and interproximal surface of the incisors, also will prohibit rotation.
