At Cronin & Czarnik Orthodontics, we’ve built a reputation as one of Colorado’s leading providers of advanced airway-focused orthodontic treatments—especially MARPE (Miniscrew-Assisted Rapid Palatal Expansion).
One of the most common concerns we hear from patients considering expansion is:
“Will I get a big gap between my front teeth?”
The short answer: not necessarily—and in our office, we actively work to avoid it.
Welcome to what we call our No Diastema Protocol—a refined, experience-driven approach to MARPE that prioritizes both function and aesthetics from day one.
What Is a Diastema—and Why Does It Happen?
A diastema is a space between the two upper front teeth. During traditional palatal expansion, the upper jaw splits at the midline suture—this often results in a temporary gap forming between the front teeth.

While this is a normal biological response, it’s not always ideal from a patient experience standpoint—especially for adults or professionals who want a more discreet treatment journey.
Our Approach: The “No Diastema Protocol”
At Cronin & Czarnik Orthodontics, we’ve spent years refining our MARPE techniques to minimize or completely avoid visible spacing during expansion

How we do it:
- Precise 3D planning using advanced imaging
Customized force vectors to control how the suture opens - Slow expansion protocol aligning with biologic norms to allow gingival tissues time to remodel
- Simultaneous tooth movement to guide the front teeth during expansion
- Close doctor monitoring and attention to detail
Because we’ve studied every detail of MARPE treatment, we’re able to apply it in ways that many offices simply can’t—delivering results that are both biologically sound and cosmetically thoughtful.
Why Experience Matters
Not all MARPE treatments are created equal.
At our practice, we:
- Customize every treatment plan to the individual patient
- Prioritize extra one-on-one doctor time
- Take a comprehensive, airway-focused approach
- Avoid “one-size-fits-all” protocols
This level of attention is what allows us to successfully implement advanced strategies like the No Diastema Protocol.
MARPE with Invisalign vs. Braces: Which Is Right for You?
One of the things that sets our office apart is our ability to offer MARPE in multiple treatment formats—tailored to your lifestyle and preferences.
Option 1: MARPE + Invisalign Clear Aligners

Pros:
- Highly aesthetic (virtually invisible)
- Easy to remove for brushing and flossing
- More flexibility for eating and social situations
Considerations:
- Requires consistent wear (20–22 hours/day)
- Patient compliance is critical for success
This is a great option for patients who value discretion and flexibility and are motivated to stay on track.
Option 2: MARPE + Braces

Pros:
- Always working—24/7 efficiency
No need to remember trays - Excellent control over tooth movement
Considerations:
- More visible than aligners
- Slightly more involved hygiene routine
Many patients prefer this option because it’s set-it-and-forget-it—no compliance concerns, just consistent progress.
The Bottom Line: Two Paths, One Exceptional Result
Whether you choose Invisalign or braces, both approaches:
- Deliver excellent final outcomes
- Support proper skeletal expansion
- Improve airway, function, and alignment
The difference lies in how you get there, not where you end up.
