Configuration Guide

Upper/Lower Jaw

Choose which part of your mouth the appliance will be made for:

  • Upper Jaw: Appliance fits only the upper teeth.

  • Lower Jaw: Appliance fits only the lower teeth.

  • Upper & Lower Jaw: Includes two appliances, one for each jaw.

Acrylic Color

Pick your favorite color for the acrylic base of the appliance. This option allows you to add a personal flair. We offer a wide range of vibrant and subtle colors.

Add Glitter

Add shimmering silver glitter to the acrylic for a sparkling finish.

Palate Design

Select the type of palatal coverage:

Full Palatal Plate

Covers the entire roof of the mouth.

Horseshoe Palatal Plate

U-shaped for a more open, tongue-friendly fit.

Add-ons

Headgear Tubes

Add stainless steel tubes to the appliance for compatibility with facebow-type orthodontic headgear.

Tongue Crib

A tongue crib helps discourage tongue thrusting and assists in breaking habits like thumb sucking.

Reverse Pull Hooks

Add special hooks to the appliance for attachment to a reverse-pull face mask. Commonly used in orthopedic correction of underbites (Class III malocclusions).

Acrylic-Covered Labial Bow

Add a layer of acrylic over the labial bow (the front wire across the teeth) for enhanced comfort and aesthetics. This option helps reduce metal visibility and can make the appliance feel smoother against the lips – great for customers with sensitivity or cosmetic preferences.

Add Cheek Guards

Add smooth acrylic cheek guards to the sides of the appliance to reduce irritation from wires or components rubbing against the inner cheeks. This option improves comfort, especially for customers with sensitive cheeks or those prone to irritation from orthodontic appliances.

Extra-Thick Acrylic

Choose extra-thick acrylic for added strength and durability. Ideal for customers who require a sturdier appliance due to heavy wear, strong bite forces, or for those who simply prefer a more robust feel. Note that this may add some bulk compared to the standard acrylic thickness.

Add Lip Bumper

Add a lip bumper, a U-shaped, acrylic-covered wire shield positioned in front of the lower teeth, designed to keep the lower lip away from the teeth and reduce lip pressure. This helps in creating space by allowing the back teeth to move naturally and preventing the lower lip from exerting unwanted forces on the front teeth. Often used in orthodontic treatment to assist with arch development and alignment.

Additional Expansion Screw

Add an extra expansion screw to the appliance for enhanced or multi-directional expansion. This option is useful when greater or segmented expansion is needed – for example, expanding different parts of the arch independently. It is commonly selected for complex orthodontic cases requiring more precise control over tooth and arch movement.

Tongue Bead (Pearl)

Add a small, smooth tongue bead (also called a pearl) to the center of the upper appliance. This tactile training aid encourages proper tongue positioning by providing a physical point of contact for the tongue tip. Commonly used to help correct tongue thrust habits, improve swallowing patterns, and support speech development.

Add Impression Kit

If you don’t already have dental impressions or digital scans, select this option to receive our easy-to-use impression kit, complete with instructions.

Our classic Twin Block appliance is a removable, two-part system designed to gently and effectively guide jaw alignment. It features interlocking upper and lower bite blocks that engage when the mouth closes, encouraging the lower jaw to move forward during wear. Over time, this promotes a more balanced muscle function and supports the development of a natural bite posture. While not intended as a medical device, the appliance is structured to encourage gentle, habit-forming positioning.

Wearing Experience:
At first, the appliance may feel slightly bulky due to the twin acrylic blocks. Most users adapt within a few days. Speaking may be temporarily affected, especially for sounds like “s” or “z,” but this usually improves with consistent use. The device fits comfortably over your teeth and is easy to remove for eating and cleaning.

Key Features

  • Upper and Lower Acrylic Blocks:
    Crafted from high-quality, smooth acrylic, each half fits snugly over the teeth. The angled blocks at the back guide the lower jaw into position during normal bite closure.
  • Occlusal Bite Surfaces:
    The inclined planes on both arches allow the upper and lower jaws to meet in a forward-guided position.
  • Stainless Steel Clasps and Labial Bows:
    These wire elements help stabilize the appliance on the teeth, ensuring it remains securely in place during everyday activities.
  • Custom Acrylic Base:
    100% BPA-free, biocompatible acrylic, available in a range of vibrant colors.
