Fixed Appliances, Palatal Expansion

HAAS Expander

The HAAS expander appliance incorporates an acrylic plate within the vault of the palate with an expansion screw. Lingual arms are laser welded to the bands integrated into the acrylic. Dr. Haas believed that more palatal coverage reduced tipping and supplied more bodily movement because of the additional coverage on the palate. With each expansion appliance, we provide a custom swivel key that has an integrated activation recording tool directly on the handle. HAAS Expander metal framework is 3D printed for the most predictable and accurate fit. The simple two-appointment process starts with a scan at appointment one and then delivery on the following date. No need for separators. Our skilled digital technicians can help you conceptualize a design that provides maximum retention for the expander appliance. Metal can be designed that runs snug to the lingual with exact fitting rests over the occlusion. Options are available to cup the lingual and the buccal. This revolutionary expander technology will change the way you serve your patients.

Treatment & Care

The typical rate of activation is one (1) per day. Each RPE requires four (4) activations per 1mm. It is Not uncommon to double up with one turn in the morning and one in the evening. Going too fast may damage periodontal membrane or roots of the teeth. Going too slow may result in producing more dentoalveolar change and less sutural split than normally desired.

This expander appliance should be cleaned every day with toothpaste and a soft toothbrush, morning and night. Encourage the patient to give sufficient time to clean thoroughly around the appliance, gums, teeth, and bands to maintain proper hygiene and prevent inflammation. 3 minutes is recommended.

More About HAAS Expander

Also Known As:

Haas appliance, Haas Rapid Palatal Expander

Who Made Me:

Dr. Andrew Haas, an orthodontist from the United States, developed the Haas Expander in the 1950s. His innovation involved a midline screw to apply transverse force, promoting maxillary expansion. Haas’s work in this area laid the foundation for modern palatal expansion techniques, and his design remains one of the most commonly used appliances for skeletal expansion. Today, the Haas Expander continues to be a popular choice in orthodontics for patients needing rapid palatal expansion.

What's the difference between Haas and Hyrax Expanders?

A Haas Expander varies from the Hyrax Expander due to the acrylic support on the palate of the Haas Expander. An orthodontist should choose one over the other based on the shape of the patient’s palate. If the transverse width and depth allows, the Haas expander is typically preferred.
