The Harvold Activator is a specific type of orthodontic appliance commonly used in the field of orthodontics. It is named after Dr. Arne Harvold, a prominent orthodontist who developed this particular device. The Harvold Activator is designed to correct dental malocclusions, such as overbites, underbites, and crossbites.
This appliance typically consists of an acrylic plate that covers the roof of the mouth (known as the palatal aspect) and extends towards the front teeth. The Harvold Activator also has wire components that connect the upper and lower jaws, allowing for the application of proper forces to bring about desired tooth movements. The appliance relies on the principle of orthopedic growth modification to stimulate favorable jaw growth and development.
When worn, the Harvold Activator applies gradual and controlled forces on the teeth and jaws, thereby encouraging the desired movement and alignment. This orthodontic device is often used in growing individuals, particularly those in their early teenage years, when the jawbones are still malleable and responsive to stimulation.
The Harvold Activator is typically custom-made by orthodontists and requires proper evaluation, fitting, and regular adjustments to ensure its effectiveness. It is a removable appliance, allowing for easy maintenance and oral hygiene practices. Patients may experience temporary discomfort or difficulty with speech during the initial adjustment period, but these typically subside as they adapt to wearing the appliance.
Overall, the Harvold Activator serves as an important tool in orthodontics, aiding in the correction of dental and jaw irregularities in growing individuals, with the goal of achieving optimal functional and aesthetic outcomes.
