Services
Traditional Metal Braces
Traditional metal braces use high-grade stainless steel brackets and archwires to straighten teeth effectively. These braces are durable and suitable for correcting complex alignment issues in children, teens, and adults. Modern designs offer enhanced comfort and allow for personalized color choices with elastic bands.
Clear Aligners
Clear aligners are removable, transparent trays that gradually reposition teeth without metal brackets. Ideal for patients seeking discreet orthodontic treatment, aligners allow unrestricted eating and oral hygiene while providing comfortable, nearly invisible correction for mild to moderate dental misalignments.
Orthognathic Surgery
Orthognathic surgery corrects severe jaw misalignments and bite issues unresponsive to braces alone. Performed in coordination with oral surgeons, this treatment combines pre- and post-surgical orthodontics to achieve proper jaw function and facial symmetry for improved oral health and aesthetics.
Ceramic Braces
Ceramic braces use tooth-colored brackets for a less noticeable appearance compared to metal braces. Recommended for older teens and adults prioritizing aesthetics, these braces require careful maintenance but offer effective correction of moderate alignment issues while maintaining a natural visual profile.
Palatal Expanders
Palatal expanders widen the upper jaw to create space for crowded teeth and improve breathing. This orthopedic appliance is most effective in growing children, addressing crossbites and airway issues by gradually expanding the palate to enhance dental alignment and nasal airflow.
