Rapid Expansion Maxillary Expander Hyrax Tooth Borne Design
Engineered specifically for pre-prosthetic preparation, this maxillary expansion appliance conditions the edentulous or partially dentate arch to receive optimal prosthetic treatment. Correcting transverse deficiency in advance of denture fabrication results in a secure, well-proportioned base, ensuring that removable full dentures, partial dentures, and implant-supported restorations all achieve superior adaptation, chewing efficiency, and long-term comfort.
Unlike conventional orthodontic expanders designed for fully dentate adolescents, this appliance is uniquely configured for the compromised dentition and resorbed ridges typical of prosthodontic patients. It is available in tooth-borne, tissue-borne, and hybrid tooth-tissue-borne designs, allowing clinicians to select the ideal retention strategy based on remaining dentition and periodontal health.
High-precision stainless steel expansion screw with fully sealed mechanism and clear activation markers. Each quarter-turn delivers controlled 0.20-0.25 mm expansion.
Medical-grade stainless steel wire (AISI 304/316L) and cobalt-chromium alloy for durability, fracture resistance, and exact force delivery.
Heat-cured, tissue-safe PMMA acrylic polished to glass-like finish to minimize irritation and plaque accumulation.
- Expands the denture-bearing area by correcting basal bone constriction and narrow ridges
- Eliminates pseudo-Class III relationships by resolving anterior crossbites
- Facilitates implant planning by creating adequate inter-arch space and ridge width
- Enhances denture stability by reducing lateral stress on denture borders
- Patient-centric comfort with lightweight construction (12-20 g) and smooth contours
Ideal for completely edentulous patients, relying on full palatal coverage and mucosal adhesion for anchorage.
Secures on remaining posterior teeth with custom bands and Adam's clasps, suitable for partial edentulism.
Recommended for patients with bruxism or deep bite to prevent unwanted tooth extrusion and protect the acrylic base.
Designed for V-shaped maxillary arches requiring targeted anterior expansion, often preceding an immediate complete denture.
Every appliance is custom-fabricated on the patient's individual dental cast, ensuring precise adaptation and maximum comfort. All materials are fully biocompatible, complying with ISO 10993 standards, and are available in BPA-free, latex-free, and nickel-free formulations. The product meets FDA Class II and CE-marking requirements and includes a dedicated activation key, patient-specific labeling, and comprehensive instructions.
The Foundation of Confident Restorations: For the prosthodontist, the Pre-Prosthetic Maxillary Expander is more than an orthodontic appliance—it is the critical first step in a predictable restorative workflow. By establishing a sound skeletal and soft-tissue base, it transforms challenging pre-prosthetic conditions into straightforward, successful denture cases.
