ADULT ORTHODONTICS
planned from a 3D scan.
MARPE widens a narrow upper jaw using small titanium anchors in the palate, placed under local anaesthetic. In many adults it avoids surgery.

Consult and 3D imaging
We tell you whether expansion suits you and what it can realistically achieve.

How it works
1
We assess your jaw, airway and bite, and explain whether expansion is suitable and what it can realistically achieve.
2
The TADs are placed under local anaesthetic in about 30 minutes, then the appliance is fitted and we show you how to use it.
3
Regular visits to track progress. Braces or aligners then move the teeth into the new space.
Suitability
We tell you whether expansion suits you and what it can realistically achieve.
Planning
Each TAD is planned on a CBCT scan.
Procedure
TADs are placed under local anaesthetic in about 30 minutes.
Next
Braces or aligners then move the teeth into the new space.
The upper jaw, or maxilla, forms the roof of your mouth and the floor of your nasal cavity. When it is too narrow, the nasal cavity above it is compressed, increasing resistance to airflow. The result can be chronic nasal obstruction, mouth breathing, snoring, and in some cases obstructive sleep apnoea. The dental consequences include crowding, posterior crossbite, and a high arched palate.
In children, the mid-palatal suture is still open and responds well to conventional expansion. By the mid-teens this suture begins to fuse, and by the early twenties it is typically interlocked. Adults were historically told that expansion was only possible surgically. Miniscrew-Assisted Rapid Palatal Expansion (MARPE) changed that.
MARPE uses small titanium screws called TADs (temporary anchorage devices), placed in the palate under local anaesthetic. They hold an expansion appliance to the bone rather than the teeth. When the appliance is turned, the force goes into the bone instead of tipping the teeth outward, which is why adults can be expanded without surgery.
In many adults MARPE widens the jaw itself, without surgically assisted expansion (SARPE) or a Le Fort osteotomy.
Because the force goes into the bone, the jaw widens rather than the teeth tipping. That tends to give a more stable result.
A CBCT scan shows the palate, bone thickness and suture in 3D. We plan where each TAD goes from that scan before the appliance is made.
Widening the palate also widens the floor of the nose. Some patients notice easier nasal breathing, though this varies from person to person.
The TADs are placed under local anaesthetic in about 30 minutes.
MARPE creates the width. Braces or aligners then move the teeth into the new space. We offer Damon braces and clear aligners for this stage.
MARPE may suit adults with a narrow upper jaw, a crossbite at the back, or crowding caused by jaw width. It is also considered where a narrow upper jaw may be adding to a blocked nasal airway. It does not suit everyone, so we check the palate, bone and suture on a CBCT scan before recommending it.
If you were told in the past that you needed jaw surgery for a narrow bite, MARPE may be an alternative. We will tell you what it can and cannot do in your case.
Yes. MARPE (Miniscrew-Assisted Rapid Palatal Expansion) delivers true skeletal expansion in many adults using small titanium screws placed in the palate, avoiding the need for surgical jaw procedures.
A narrow upper arch, a crossbite at the back, crowding caused by jaw width, and in some cases a restricted nasal airway.
The TADs are placed under local anaesthetic in about 30 minutes. You can expect some pressure while the appliance is being turned.
Active expansion typically runs 3-6 months, followed by a consolidation period of 6-12 months before the appliance is removed and orthodontic treatment begins.
It depends on your palate, bone and suture. We check these on a CBCT scan at your consult and tell you what MARPE can do for your case.
We begin with a consult and 3D imaging to assess your jaw, airway and bite. We explain clearly whether expansion is suitable for you and what it can realistically achieve.
If we go ahead, you are fitted with an appliance and shown how to use it. We see you for regular reviews to track progress and keep everything comfortable.
We work through the plan at a steady pace and keep you informed at every stage, with the timeframe and costs set out from the start.

Adult jaw expansion
We take a CBCT scan, explain your options and tell you what expansion can achieve for you. There is no obligation to go ahead.
