Braces
Traditional metal braces and Clarity ceramic brackets provide effective tooth alignment solutions for children, teens, and adults. Our customized treatment plans ensure optimal results while maintaining comfort and aesthetics. The durable, stain-resistant ceramic brackets offer discreet alternatives to metal braces with colorful elastic options. Treatment duration and specific techniques are tailored to each patient's unique dental needs and lifestyle requirements.
Invisalign
Invisalign treatment uses clear, removable aligners to straighten teeth discreetly for teens and adults. This modern alternative to traditional braces offers greater comfort and convenience while maintaining effective results. Our practice provides personalized Invisalign treatment plans with regular progress monitoring to ensure proper tooth movement. The virtually invisible aligners can be removed for eating and oral hygiene maintenance.
Phase 1 Treatment
Phase I orthodontic treatment addresses developing bite and alignment issues in children around age seven. Early intervention can correct jaw growth problems and create proper space for permanent teeth eruption. This proactive approach often reduces future treatment complexity while promoting optimal facial development. Treatment typically involves expanders or partial braces during the mixed dentition stage.
Retainers
Custom retainers maintain teeth alignment after orthodontic treatment completion. We offer removable clear plastic retainers and bonded lingual retainers for long-term stability. The Memotain precision retainer provides maximum comfort through digital customization. Proper retainer use ensures lasting results from your orthodontic investment while preventing unwanted tooth movement.
Surgical Orthodontics
Surgical orthodontics combines braces with jaw surgery to correct severe bite issues and facial imbalances. This comprehensive approach addresses complex cases involving malocclusion and skeletal discrepancies. Treatment improves both functional bite relationships and aesthetic facial harmony. Our team coordinates care with oral surgeons for optimal long-term outcomes in challenging orthodontic cases.

We have had a fantastic experience from beginning to end with Zirbel Orthodontics. My daughter had traditional braces and her team did a wonderful job of not only straightening our teeth, but also making the whole experience as best as it could be. I highly recommend Dr. Zirbel and her great team!

Our experience with Dr. Zirbel and staff is always top of the line. They are flexible, friendly, and understanding of scheduling needs due to school and work. Their care is genuine and they work hard to help give you a great smile, good-looking teeth, and honest advice.

I recently had my son's first Ortho consult and the entire experience was beyond my expectations, from the front desk staff, assistants and Dr Zirbel, herself. The facility is warm and inviting and all questions were answered with ease. Highly recommended!

I had my braces placed and removed at this location around 15 years ago. This past week my permanent retainer came unglued and the staff welcomed me back with open arms. They had photos of my teeth from years ago readily available and were able to show me some minor movements my teeth have made since the retainer has not been glued. They promptly fixed my retainer and I was out the door 30 minutes later. Cannot recommend this practice enough; not to mention the facility is beautiful and inviting as ever.
