Services
Invisalign Treatment
Invisalign offers a discreet alternative to traditional braces using custom-fitted plastic aligners. This treatment straightens teeth without metal brackets, reducing mouth irritation while maintaining aesthetic appeal. Our Invisalign Diamond Provider status ensures advanced expertise in creating personalized treatment plans for optimal results.
Traditional Braces
Modern traditional braces provide effective tooth alignment with improved comfort and efficiency. We offer color customization options for brackets and wires, allowing patients to personalize their treatment experience while achieving precise orthodontic corrections for complex bite issues.
Early Orthodontics
Early intervention addresses developing bite problems in children aged 7-10. This two-phase approach corrects skeletal discrepancies before all permanent teeth erupt, potentially reducing future treatment complexity and duration through strategic jaw development guidance.
PROPEL Accelerated Orthodontics
PROPEL technology reduces treatment time by stimulating bone remodeling during orthodontic movement. This minimally invasive procedure creates micro-osteoperforations that accelerate tooth alignment, often completing treatment in half the conventional duration without compromising quality.
iTero Digital Scanning
Our iTero Element 5D scanner creates precise digital impressions without messy putty. This technology enhances diagnostic accuracy, improves patient comfort, and enables real-time visualization of potential treatment outcomes through advanced 3D imaging capabilities.
