What are Lower Jaw Expanders?
Lower jaw expanders are dental appliances that are designed to expand the lower jaw, allowing more space for teeth to move into proper alignment. This expansion is particularly useful for treating patients with a Narrow upper jaw or those who have拥挤的牙齿, overbite, underbite, or crossbite. Lower jaw expanders are typically used in adult patients who are seeking orthodontic treatment to correct these issues without the need for surgery.
Why are Lowerjaw Expanders Different from Upperjaw Expanders?
While both upper and lower jaw expanders serve to correct poorly aligned jaws, the lower jaw expander is designed specifically for the lower jaws. The procedure involves attaching a metal bracket to the back molars and spanning the lower arch. A specialized key or remote controls the expansion force that gently pushes the lower jaw bones apart. This expansion creates more room for the tongue, and aids in correcting improper bites and reducing the risk of teeth getting拥挤.
How are Lowerjaw Expanders Applied?
The application of a lower jaw expander typically involves several follow-up visits to the dentist. During your initial appointment, the expanders are fitted and the area around the molars is numbed. The expanders are then activated, usually by turning a small screw located in the middle of the expander, causing the lower jaw to slowly expand. Each visit, the expansion force is increased slightly to safely accommodate the growth of the lower jaw.
Lower jaw Expander Candidates
Lower jaw expanders are typically recommended for adults who have a narrow higher jaw (maxillary dental arch),拥挤的牙齿, overbite, underbite, or crossbite. They are also useful for younger patients with growing jaws but are often not recommended for children under the age of 7, as the roots of their teeth have not yet fully developed. Your dentist will evaluate your specific case and determine if a lower jaw expander is the right treatment option for you.
Benefits of Lowerjaw Expanders
Lower jaw expanders offer numerous benefits for adults with improperly aligned jaws. The expansion process can help correct:
- Severe overjet (upper front teeth protrude)
- Deep overbite (lower front teeth cover the upper front teeth)
- Crossbite (upper teeth cover the inner surfaces of lower teeth)
- Underbite (lower front teeth protrude excessively)
By correcting these issues, lower jaw expanders can improve the patient's bite, appearance, and overall oral health. Additionally, expanded lower jaws are less likely to拥挤 in the future, reducing the need for further orthodontic treatment.
Complications and Risks
While lower jaw expanders are generally considered safe and effective, as with any dental procedure, there are potential risks and complications associated with their use. These include:
- Pain and swelling in the jaw area during activation
- Discomfort or sensitivity in the teeth and gums
- Changes in speech due to the expansion of the lower jaw
- Relatively minor dental work required during the expansion phase
- Risk of damage to the temporomandibular joints (TMJs) if not properly adjusted
It is important to discuss these risks and any other concerns with your dentist before undergoing lower jaw expansion therapy. Your dentist will monitor your progress carefully and make any necessary adjustments to ensure your safety and comfort throughout the treatment process.
How Long Does it Take to See Results?
The amount of time needed to see results from a lower jaw expander depends on several factors, including the severity of your condition, your age, and your response to the expansionforce. Typically, it can take anywhere from a few weeks to a few months for the lower jaw to expand sufficiently to achieve optimal alignment. Your dentist will keep you up to date with your progress and provide you with detailed instructions on how to care for your expanders.
Getting the Best Results
To obtain the best results from your lower jaw expander, it is important to follow your dentist's instructions carefully and practice good oral hygiene habits. Avoid opening your mouth widely until the expansion is complete, and use special mouthguards or nightguards to protect your jaws from injury during the expansion phase. Additionally, continue your regular check-ups and cleanings with your dentist to ensure that your treatment is progressing as planned.
##Lower jaw expanders provide a safe and effective alternative to traditional orthodontic treatment for adults with improperly aligned jaws. By expanding the lower jaw and creating more space for teeth, these appliances can help correct a wide range of dental issues, including overbite, underbite,拥挤, and crossbite. If you're an adult considering lower jaw expansion therapy, talk to your dentist to discuss your options and determine if this treatment is right for you.
