Palatal expansion
Palatal expansion, also known as SARPE treatment (Surgically Assisted Rapid Palatal Expansion), is a surgically assisted rapid palatal expansion that is primarily used to treat malocclusions and narrow upper jaws. It is often used in adults or adolescents whose upper jaw growth is already complete, as conventional palatal expansion without surgical intervention is not sufficient for them.
Procedure for palatal expansion (SARPE)
First, the patient is examined by the orthodontist and x-rays are taken to determine the exact width of the upper jaw and to create the treatment plan.
The actual procedure is performed by an oral surgeon under general anesthesia. The upper jaw is cut along certain lines (usually in the palate area and the maxillary sinuses). This makes the upper jaw more flexible to allow expansion through the palatal expansion apparatus.
A special palatal expansion appliance (expander) is attached to the upper jaw immediately after the operation or a few days later. This expander is gradually activated by the patient or the orthodontist to stretch the jaw. The expander is adjusted using a small key or screw and ensures that the two halves of the upper jaw are slowly pulled apart.
This phase usually lasts 2-4 weeks. During this time, the palate is gradually stretched so that the upper jaw becomes wider. This is done gradually to relieve the bone and allow for even expansion.
After active expansion, the expander remains in the mouth for several months to stabilize the new position of the upper jaw and give the bone time to grow back together. This phase is important to prevent a relapse.
Successful palatal expansion can often be followed by orthodontic treatment with braces to bring the teeth into the correct position.
Preparation
A thorough examination of the upper jaw is carried out at the beginning. This includes dental impressions, X-rays (e.g. OPG, 3D imaging) and photos to determine the exact anatomy and extent of the jaw misalignment.
Based on the examination results, the orthodontist creates a precise treatment plan. This determines how much the upper jaw needs to be extended and which measures are necessary before and after treatment.
As the procedure is performed under general anesthesia, a general health check is carried out. Any pre-existing conditions or medication that could affect the surgical procedure will be taken into account.
The patient receives instructions, such as not taking certain medications (e.g. blood thinners), to minimize the risk of complications. They will also be informed about abstinence from food before the operation (usually not eating or drinking anything for several hours before the anaesthetic).
The oral surgeon informs the patient about the exact procedure of the SARPE operation, possible risks and the postoperative course. Important points such as pain management, the healing process and aftercare are discussed in detail.
Indications for the need for palatal expansion
If the upper jaw is too narrow for the lower jaw, this can lead to problems with chewing and speaking.
A narrow upper jaw often leads to a crossbite, in which the upper teeth bite behind the lower teeth.
A narrow jaw can lead to dental crowding as there is not enough space for the teeth.
Advantages of SARPE treatment
It enables a significant extension of the upper jaw, which would not be possible with purely orthodontic methods in adults.
A narrow upper jaw is corrected, which improves the bite and the function of the teeth.
By widening the upper jaw, the smile often becomes wider and more harmonious.
