Rapid Palatal Expander – RPE

Used for slow or rapid palatal expansion to create space to uncrowd the arch and create better arch form. Rapid expansion can help open the airway. It can also be used to correct a posterior crossbite.

npe

Nitanium Palatal Expander- NPE

Pre-activated, self activating upper expansion appliance that provides slow expansion to create space to uncrowd the teeth and create better arch form. Also rotates the molars to create some arch length. Only available for the Upper arch.

TransForce Transverse Expander

TransForce Transverse Expander

Pre-activated, self activating upper or lower expansion appliance that provides slow expansion to create space to uncrowd the teeth and create better arch form. Can be made for the upper or the lower arch.

Fan Expander Fixed Dental Appliance

Fan Expander

Maxillary Expansion Appliance to widen the anterior portion of the arch. The screw opens in a fan or wedge and a hinge in the posterior prevents expansion in the molar region. Good appliance to correct ā€œVā€ shaped arches and uncrowd the anterior segment.


Fixed Schwartz

Mandibular slow expander to upright the posterior teeth to create space to uncrowd the lower arch and create better arch form. It is good for adults and children.

3D Skeletal Expander Fixed Dental Appliance

3D Skeletal Expander

Mandibular slow expansion appliance. A smaller screw is placed in acrylic and is more gentile to the tongue. Good option when there is a severely lingual incisor that is blocked out of the arch. It is fabricated on Wilson 3D slots for easy adjustments.


Williams Expander

Mandibular expander for younger patients where the 1st molars have not erupted enough to band. A wire is extended to the 1st molars so they will expand along with the rest of the arch. A lingual wire helps to align the anteriors as the arch is expanded.


3D Wilson Multi Action

Maxillary light wire Fixed/Removable appliance that can be used to widen the arch and flare the anteriors forward. The appliance can be removed from the bands for the doctor to activate it, but the patient cannot remove it.

3d Wilson QUAD ACTION Fixed Dental Appliance

3D Wilson Quad Action

Mandibular version of the Multi Action. Fixed/Removable appliance to widen the lower arch, upright the posterior segments and flare the anteriors forward. The appliance can be removed from the bands for the doctor to activate it, but the patient cannot remove it.

Super Screw Expander Fixed Dental Appliance

Super Screw Expander

Maxillary expander used for slow or rapid expansion. It is similar to the RPE, but uses a different type of screw. The screw requires a special wrench to activate it. Some patients find it easier to adjust than the RPE screw.


E – Arch

Maxillary or Mandibular pre-activated expansion appliance. The open coil spring provides the force to expand the arch. There is nothing that needs to be adjusted or activated by the doctor or the patient.


Upper CD Distalizer

Maxillary molar distalizing appliance to create arch length to uncrowd the arch. The doctor is in complete control of the activation and the amount of distalization that occurs. It is strong enough to distalize the 1st and 2nd molars together. Requires no patient compliance.


Lower CD Distalizer

Mandibular molar distalizing appliance to create arch length to uncrowd the arch. The doctor is in complete control of the activation and the amount of distalization that occurs. It is strong enough to distalize the 1st and 2nd molars together. Requires no patient compliance.

TransForce Sagittal Fixed Dental Appliance

TransForce Sagittal

Maxillary or Mandibular appliance to flare the anteriors forward. The appliance is pre-activated and pre-adjusted to move the teeth. Composite Anchors are needed on the lingual of 2 teeth to hold the appliance in place and prevent it from riding up the lingual of the teeth.


3 Way Barrel Expander

Maxillary 3 screw Sagittal to expand the arch and develop the premaxilla forward. Creates arch width and length to uncrowd the arch and advance a deficient Premaxilla.

CD_Advancer_Fixed_Dental_Appliance

CD Advancer

Maxillary Anterior Drive Sagittal to advance the premaxilla forward. An expansion screw can be added if needed. The doctor makes all the adjustments. Composite Anchors should be placed on the lingual of 2 anterior teeth to prevent the appliance from sliding down the lingual of the teeth and help direct the force in the proper direction.


Magill Sagittal

Maxillary or Mandibular Sagittal appliance with multiple design options. An expansion screw can be added if needed. The appliance can be designed to distalize or drive the premaxilla forward. This is a patient activated appliance.


Rick-a-Nator

Maxillary bite plane to advance the mandible and increase the vertical. The bite plane can be flat for vertical only or an incline plane to advance the mandible and help open the bite. Made with Wilson 3D Slots on the molar bands so it can be removed without having to take off the bands.

Rickinator Plus Fixed Dental Appliance

Rick-a-Nator Plus

Rick-a-Nator with an expansion screw to widen the arch. The bite plane can be flat or inclined. Made with Wilson 3D Slots on the molar bands so it can be removed without having to take off the bands.



Banded Twin Block

Fixed version of the Twin Block to correct Class II Division I cases. Proper arch form is needed before using this appliance. This appliance will advance the mandible and reduce the overjet but will not increase the vertical. A Rick-a-Nator is placed after the Twin Block to help increase the vertical and close the posterior open bite.



Banded Herbst

Maxillary and Mandibular appliance that work together to advance the mandible and correct Class II cases. The mandible can be advanced during treatment by adjusting the buccal arms if additional advancement is needed.


Upper Schwartz

Maxillary slow expansion appliance to create space to uncrowd the arch and create better arch form. It can be used for adults and children.


Lower Schwartz

Mandibular slow expansion appliance to upright the posterior teeth, create space to uncrowd the arch and create better arch form. It can be used for adults and children.


Posterior Crossbite Corrector

Maxillary Schwartz Expander with posterior occlusal coverage to allow the posterior crossbite to be corrected without occlusal interference as the arch is expanded.


Fan Expander

Maxillary Expansion Appliance to widen the anterior portion of the arch. The screw opens in a fan or wedge and a hinge in the posterior prevents expansion in the molar region. Good appliance to correct ā€œVā€ shaped arches and uncrowd the anterior segment.


Nord Unilateral Expander

Maxillary Expansion Appliance to correct a unilateral posterior crossbite. The cut in the acrylic is angled so it will only push on the teeth in crossbite. Occlusal coverage will allow the crossbite to be corrected without interference with the lower arch.


Anterior Drive Sagittal

Maxillary appliance to create arch length by flaring the anteriors forward or developing the Premaxilla forward. Helps correct Division 2 incisors and anterior crossbites.


Distal Drive Sagittal

Maxillary appliance to create arch length by distalizing the posterior segments. Helps to uncrowd the arch and make room for blocked out cuspids. The 2nd molars need to be extracted for optimal distal movement.


3 Screw Anterior Drive Sagittal

Maxillary appliance to expand and create arch length at the same time by flaring the anteriors forward and developing the premaxilla forward. Combination of the Schwartz and Sagittal appliances.

3-Way Screw Fixed Dental Appliance

3-Way Screw Appliance

Maxillary appliance with one screw that allows you to expand and flare the anteriors forward. Best used in younger patients. Not as thick as having 3 separate screws.


Lower Sagittal

Mandibular appliance to create arch length. With the second molars in place, the appliance will flare the anteriors forward. With the second molars extracted, the appliance will distalize the posteriors.



Twin Block

Class II correction appliance. Upper and lower appliances work together to bring the mandible down and forward to a Class I relationship. Proper Upper arch form is important, so there is room for the mandible to come forward. It will help reduce the overjet and open the dental deep bite.

3-Way Screw Fixed Dental Appliance

Bionator

One piece appliance that both arches fit into. It is fabricated with the mandible down and forward to correct a Class II Division I relationship. It works similar to the Twin Block, but will take longer to correct the Class II relationship. Also used as a night time retainer to maintain the Class II correction long term.
