PALATAL EXPANSION · BUFFALO, NY

More room for a balanced bite.

Explore MARPE and SARPE two approaches to widening a narrow upper jaw and supporting your orthodontic treatment plan.

UNDERSTANDING PALATAL EXPANSION

A wider foundation. A better-fitting bite.

A narrow upper jaw can affect how the upper and lower teeth meet. Palatal expansion is designed to increase the width of the upper jaw as part of a coordinated orthodontic treatment plan.

MARPE and SARPE use different approaches to achieve expansion. The right option depends on your jaw anatomy, skeletal maturity, gum and bone health, and treatment goals.

TWO APPROACHES. ONE PERSONALIZED PLAN.

MARPE or SARPE?
Understand the difference.

Both approaches use an expansion appliance. The main difference is how the upper jaw is prepared for expansion.

MINISCREW-ASSISTED EXPANSION

MARPE

Miniscrew-Assisted Rapid Palatal Expansion

An expander anchored with small screws in the palate applies expansion forces to the upper jaw.

  • May offer an option without surgical bone cuts for selected patients.
  • Suitability depends on anatomy and skeletal maturity.
  • Requires monitoring and appliance adjustments as directed.

SURGICALLY ASSISTED EXPANSION

SARPE

Surgically Assisted Rapid Palatal Expansion

A surgical procedure helps release resistance in the upper jaw so an expander can gradually widen it.

  • May be considered when skeletal resistance limits expansion.
  • Combines surgical care with orthodontic treatment.
  • Includes a surgical recovery period and follow-up visits.
Neither approach is right for everyone. Your surgeon and orthodontist will discuss the expected benefits, limitations, risks, and alternatives before recommending treatment.

IS EXPANSION RIGHT FOR YOU?

Start with the whole picture.

A consultation helps determine whether the upper jaw is narrow and whether expansion would support your bite and orthodontic goals.

A narrow upper jaw
Assessment of the upper jaw’s width and its relationship to the lower jaw.
A crossbite or bite imbalance
Evaluation of how the teeth come together and the underlying skeletal relationship.
Orthodontic treatment needs
Coordination with your orthodontist to understand how expansion fits into your overall plan.
Your individual anatomy
Review of skeletal maturity, oral health, and imaging when indicated.

IS EXPANSION RIGHT FOR YOU?

Start with the whole picture.

01

Consultation

Discuss your concerns, review your history, and evaluate your bite and jaw.

02

A coordinated plan

Your surgical and orthodontic teams determine the approach, appliance, and sequence of care.

03

Expansion & monitoring

Follow your team’s specific activation and care instructions, with visits to check your progress.

04

Stabilization & alignment

The appliance remains as directed while the expanded jaw stabilizes and orthodontic care continues.

QUESTIONS, ANSWERED

Feel informed. Move forward with confidence.

Your consultation is the time to ask questions and understand your individual treatment plan.

1How do I know which option I need?
Your surgeon and orthodontist consider your jaw width, skeletal maturity, oral health, and imaging. Age alone does not determine which approach is appropriate.
2Will I still need braces or clear aligners?
Expansion addresses jaw width. Braces or clear aligners may still be needed to align the teeth and refine the bite. Your orthodontist will explain how these steps fit together.
3What should I expect during recovery?
Pressure or soreness may occur during expansion. SARPE also involves surgical recovery, which may include swelling and dietary changes. Your team will explain pain management, oral hygiene, eating, and activity instructions for your procedure.
4How long does treatment take?
The activation phase, stabilization period, and overall orthodontic treatment vary. Your team will provide a timeline based on your procedure and response to treatment.
5What are the risks?
Potential risks include discomfort, gum or bone changes, tooth effects, uneven or unsuccessful expansion, and relapse. Surgical treatment adds risks such as bleeding, infection, and anesthesia complications. Your surgeon will review the risks specific to your plan.
6What should I bring to my consultation?
Bring your orthodontist’s referral or treatment information if available, a current medication list, and relevant medical and dental records. Ask the office whether existing imaging should be sent before your visit.
