Orthodontic treatment often focuses on expansion, a technique used to correct crowding and misalignment by widening the jaw. Whether for children, teenagers, or adults, expansion can deliver life-changing results when done correctly and with the right method.
In this guide, we’ll explore the different types of orthodontic expansion and how they’re used across age groups, from early intervention in young children to advanced techniques for adults.
In growing children, the jaw bones are still developing, making them more responsive to orthodontic intervention. Jaw expansion during childhood can greatly improve dental alignment, function, and facial balance—with less complexity than treatment later in life.
Custom-made to fit over the teeth, these appliances apply gentle pressure to slowly widen the upper jaw. This type will mostly result in dental tippiing, rather than ture bone expansion.
These devices are bonded to the teeth and provide more control, making them ideal for more significant expansion needs—such as treating moderate to severe crowding or crossbites.
As patients get older, the jawbones become more rigid, making traditional expansion more difficult. But with today’s innovations, adult palatal expansion is not only possible—it’s often very successful.
SARPE combines orthodontics and minor surgery. A surgeon gently separates the fused palatal bones, allowing an expander to gradually widen the upper jaw. This method is best suited for severe skeletal constriction.
A less invasive alternative to SARPE, MARPE uses small titanium screws (TADs) to anchor the appliance and assist expansion. It’s typically recommended for mild to moderate cases.
Both SARPE and MARPE require collaboration between the orthodontist and oral surgeon to ensure safe, effective outcomes.
One of the most innovative advancements in adult orthodontics is the WIN System, developed by Professor Dirk Wichmann. This system uses fully customised lingual appliances placed behind the teeth—making treatment virtually invisible.
While not suitable for all cases, the WIN System is an excellent choice for adults seeking a non-surgical, aesthetic alternative to SARPE or MARPE. It’s especially appealing for professionals or anyone looking to avoid visible braces.
Orthodontic expansion has evolved significantly, with options now available for patients at any age. Whether it’s:
…modern orthodontics offers tailored, evidence-based solutions to meet your needs.
Before starting any treatment, it’s essential to consult with a qualified orthodontist. A proper evaluation will determine the most effective and appropriate expansion method based on your age, dental condition, and long-term goals.
