What is a Palatal Expander?
At Andros Orthodontics in Pasco, Dr. Nicholas Andros specializes in using palatal expanders, a modern and effective orthodontic device. A palatal expander, also called a rapid palatal expander (RPE), is a device custom-made to gently and consistently widen the upper jaw. This treatment creates the space needed for proper tooth alignment and a healthier bite.
Types and Mechanism of Palatal Expanders
Rapid Palatal Expander (RPE)
Bone-Borne Expanders
Miniscrew-Assisted RPE (MARPE)
The Process of Impression or Scan and Placement of Separators
We utilize state-of-the-art technology for your comfort and convenience.
Impression and Digital Scan
We’ve upgraded from traditional impression methods to advanced digital scanning technology. This provides a far more comfortable experience while achieving greater accuracy for designing your custom expander.
Placement of Spacers or Separators
Before fitting your expander, if necessary, we carefully place gently to create room between teeth for the expander. Depending on the type of expander, spacers may not be required.
Advantages of 3D Printed Appliances and Digital Scans
We use advanced digital workflows to design and create highly accurate expanders. This technology reduces the need for adjustments and makes treatment more comfortable for patients.
Digital Workflow in Palatal Expander Fabrication
Our clinic utilizes innovative digital tools to create virtual models of your mouth, ensuring your expander is uniquely customized for your dental needs.
Effectiveness and Outcomes
This treatment is effective in addressing maxillary deficiencies, especially during growth phases. Expanding the palate can improve tooth alignment while providing benefits like better nasal breathing, especially for patients with habits like mouth breathing.
Palate Expanders, Airway Improvement, Snoring and Sleep Apnea
Beyond dental alignment, palatal expanders do more than just improve dental and bite alignment. Many patients experience improved breathing and better sleep patterns after treatment, with reduced snoring and symptoms of sleep apnea.
Impact on Speech and Comfort
Though there may be a short adjustment period, most patients adapt quickly to their expanders. Our team provides thorough support to ensure your comfort and success during treatment.
Impact on Sleep Apnea and Snoring
Obstructive Sleep Apnea (OSA) can cause snoring and interruptions in breathing during sleep. By expanding the upper airway, a palatal expander may improve airflow, resulting in reduced symptoms and better-quality sleep.
Clinical Evidence
Studies have confirmed that certain techniques for airway expansion can significantly reduce sleep apnea symptoms in adults, making this a potential treatment for sleep-related breathing issues.
Early Orthodontic Intervention
Early orthodontic care in children can be crucial. Expanding the palate during growth can help ease overcrowding and may also improve airflow, reducing breathing-related risks such as developing sleep apnea later in life.
Importance of Comprehensive Diagnosis
Advanced 3D imaging is essential for identifying airway concerns, offering a comprehensive view of the airway’s structure. This technology enables the creation of highly accurate and tailored treatment plans for each patient.
