What is Rebase?

Last updated: March 12, 2024

What is a rebase procedure?

A rebase procedure in dentistry involves replacing the pink acrylic part of a denture or dental appliance while keeping the existing teeth or metal framework intact. Over time, the base of a denture may deteriorate, causing it to become ill-fitting or uncomfortable. In such cases, a rebase is recommended to adjust the fit of the denture and ensure it sits comfortably in the mouth.

During a rebase procedure, the dentist will take impressions of the existing teeth or framework of the dental appliance. These impressions are used to create a new acrylic base that fits snugly against your gums. The old pink acrylic base is then replaced with the newly fabricated one. The goal of a rebase is to restore the proper fit of the denture, ensuring it is stable, comfortable, and functional for the patient.

There are several reasons why a patient may need a rebase for their dental appliance. The most common reason is wear and tear on the acrylic base over time, which can lead to a loose or uncomfortable fit. Other reasons for a rebase include changes in the shape of the gums or jawbone due to bone resorption, which can affect the fit of the denture. Additionally, accidents or damage to the denture may also necessitate a rebase to restore its functionality.

A rebase appointment typically takes about one to two hours, depending on the complexity of the procedure and the extent of adjustment needed. Most patients do not experience any pain during a rebase, as the procedure is done under local anesthesia to ensure comfort. After a rebase, patients may need a short adjustment period to get used to the new fit of their dental appliance. However, any discomfort or sore spots can usually be addressed by the dentist during a follow-up visit.

It is essential to follow your dentist's instructions on caring for your dental appliance after a rebase. Proper maintenance, including regular cleaning and storage, can help prolong the lifespan of your denture and ensure optimal oral health. If you have dental insurance, it's advisable to check with your provider to see if a rebase procedure is covered under your plan.

In conclusion, a rebase procedure is a common dental treatment that aims to improve the fit and comfort of a denture or dental appliance. By addressing issues with the acrylic base, a rebase can help restore function and confidence for patients wearing dentures.

Why might I need a rebase for my dental appliance?

A rebase procedure for a dental appliance may be necessary for several reasons. Dental appliances like dentures or partial dentures are custom-made to fit your mouth perfectly. Over time, due to changes in the structure of your mouth or normal wear and tear, the fit of the appliance may become loose or uncomfortable. When this happens, a rebase procedure can help restore the proper fit and function of the appliance.

One common reason for needing a rebase is significant weight loss or gain. Changes in your body weight can also affect the shape and structure of your mouth. If you've experienced a noticeable change in weight, your dentures or partial dentures may no longer fit securely. A rebase procedure allows the dentist to adjust the base of the appliance to match the new contours of your mouth, ensuring a comfortable and secure fit.

Another reason for a rebase could be natural changes in the bone structure of your jaw. Over time, the bone that supports your teeth and dental appliances can shrink or resorb, altering the alignment of your teeth and affecting how your appliance fits. By performing a rebase, your dentist can realign the base of the appliance to accommodate these changes in your jaw, restoring comfort and function.

Additionally, normal wear and tear on your dental appliance can cause the base to wear down or become damaged. This can lead to discomfort, difficulty chewing, or even sores in your mouth. A rebase procedure involves replacing the base of the appliance with a new material, ensuring a snug and comfortable fit once again.

It's important to note that the need for a rebase can vary from person to person based on individual factors like oral health, lifestyle, and overall health. If you are experiencing discomfort, looseness, or other issues with your dental appliance, it's best to consult with your dentist. They can evaluate your specific situation and determine if a rebase procedure is the best solution to restore the fit and function of your appliance.

How long does a rebase appointment typically take?

A rebase procedure at the dental office typically involves refitting the base of a dental appliance to improve its fit and function. The appointment duration for a rebase can vary depending on various factors, such as the type of dental appliance being rebased, the complexity of the procedure, and the individual patient's needs.

On average, a rebase appointment can take anywhere from 30 minutes to a few hours. It is essential to allocate sufficient time for the procedure to ensure that the dentist or dental technician can perform the rebase accurately and adjust the appliance correctly.

During the rebase appointment, the dental provider will begin by examining the current condition of the dental appliance and assessing the areas that need adjustment or refitting. This evaluation is crucial to determine the extent of the rebase needed and ensure that the appliance will fit comfortably and securely in the patient's mouth.

The actual process of rebasing the dental appliance involves removing the base material, adjusting the fit as necessary, and creating a new base to replace the old one. This may require taking impressions of the patient's mouth to create a custom-fit base that aligns properly with the rest of the appliance.

Once the new base is fabricated, it is securely attached to the existing framework of the dental appliance. The dental provider will make any final adjustments to ensure that the rebase fits accurately and functions correctly. Patient comfort and functionality are key priorities during the rebase procedure.

After the rebase is completed, the dental provider will provide instructions on how to care for the newly adjusted appliance. It is essential for patients to follow these care guidelines diligently to maintain the longevity and effectiveness of the dental appliance.

It's important to note that the duration of a rebase appointment and the specific steps involved can vary from case to case. Patients should consult with their dental provider to get a more personalized overview of what to expect during their rebase appointment.

Will I experience any pain or discomfort during a rebase?

During a rebase procedure, patients should not experience significant pain or discomfort. The process involves replacing the entire base of a dental appliance, such as dentures or a partial denture, to ensure a proper fit. While discomfort is typically minimal, some patients may feel slight pressure or tightness as the new base is positioned securely.

Dentists and dental technicians take great care to ensure that the rebase process is as comfortable as possible for the patient. Before beginning the rebase, the dentist will administer a local anesthetic to numb the areas of the mouth being worked on. This helps to minimize any potential discomfort during the procedure. Patients may feel a slight sensation of pressure or movement as the appliance is adjusted and fitted, but it should not be painful.

It is important for patients to communicate any discomfort they may be experiencing during the rebase procedure to their dental provider. Dentists are skilled at managing patient comfort and will make adjustments as needed to ensure a positive experience. Patients should feel free to speak up if they are feeling any pain or discomfort during the procedure so that the dental team can address it promptly.

After the rebase is completed, some mild soreness or discomfort may be experienced as the mouth adjusts to the newly fitted appliance. This discomfort is usually temporary and can be managed with over-the-counter pain medications if needed. Patients are advised to follow any post-rebase care instructions provided by their dentist to promote healing and comfort.

Overall, while some minor discomfort or pressure may be felt during a rebase procedure, it is not typically painful. Dentists strive to make the experience as comfortable as possible for the patient and will address any concerns or discomfort promptly. Open communication with the dental team and following post-procedure care instructions are important steps in ensuring a smooth and comfortable rebase process.

How often should I have a rebase done on my dental appliance?

How often should I have a rebase done on my dental appliance?

The frequency of needing a rebase for a dental appliance can vary depending on several factors. A rebase, also known as a denture reline, is a procedure done to ensure that your dentures fit properly and comfortably in your mouth. Over time, the shape of your jawbone and gum tissue can change, causing your dentures to become loose or ill-fitting. Here are some key points to consider regarding the timing of when to have a rebase done on your dental appliance:

  1. Individual Factors: The rate at which your jawbone changes can be influenced by individual factors such as age, bone density, and overall oral health. Some people may experience more significant changes in their jaw structure over time, while others may see minimal changes. It is essential to have regular check-ups with your dentist to assess the fit of your dentures and determine if a rebase is necessary.

  2. Comfort and Functionality: If you start noticing that your dentures are becoming loose, causing discomfort, difficulty chewing, or speaking, it may be time to consider a rebase. Ill-fitting dentures can not only be uncomfortable but can also lead to sores, irritations, and difficulty eating a balanced diet.

  3. Denture Age: As dentures age, they may start to wear down, leading to changes in their fit. Dentures that have been in use for several years may require more frequent rebases compared to newer ones. Your dentist can evaluate the condition of your dentures and recommend if a rebase is needed.

  4. Dental Hygiene: Proper maintenance of your dentures, including regular cleaning and care, can help prolong their lifespan and reduce the frequency of needing a rebase. It is essential to follow your dentist's instructions on how to clean and store your dentures properly.

  5. Consult Your Dentist: Ultimately, the best way to determine how often you should have a rebase done on your dental appliance is to consult your dentist. They can assess the fit of your dentures, monitor any changes in your oral structures, and recommend the appropriate timing for a rebase based on your individual needs.

In conclusion, the frequency of needing a rebase for your dental appliance can vary depending on individual factors, comfort, functionality, denture age, and dental hygiene practices. Regular dental check-ups and communication with your dentist are key in ensuring that your dentures fit well and provide optimal support for your oral health and overall well-being.

Are there any risks or complications associated with a rebase?

  1. Are there any risks or complications associated with a rebase?

During a rebase procedure, where a new base is added to a dental appliance such as dentures or retainers, there are generally minimal risks or complications involved. However, it's important to be aware of some potential factors that may arise during or after a rebase.

One common risk associated with a rebase is the possibility of minor adjustments being needed after the procedure. The dental appliance may need to be further refined to ensure a proper fit and comfort level for the patient. This adjustment phase is normal and is typically addressed by the dental professional during a follow-up visit.

Another possible complication is temporary soreness or discomfort in the mouth following a rebase. Since the dental appliance has undergone modifications, it may take a little time for the mouth tissues to adjust to the changes. This discomfort is usually mild and can be managed with over-the-counter pain relievers, if necessary.

In some cases, there could be a risk of developing pressure sores or ulcers on the gums if the dental appliance exerts excessive pressure in certain areas. This risk can be mitigated by promptly notifying your dentist of any discomfort or sore spots so that necessary adjustments can be made to alleviate the pressure points.

Patients who undergo a rebase procedure may also experience a temporary alteration in speech or eating habits. This is typically a short-term issue as the mouth adapts to the modified dental appliance. Practicing speaking and eating with the new base can help accelerate the adjustment process.

It's essential to follow your dentist's post-rebase care instructions diligently to minimize any risks and ensure optimal healing. Maintaining good oral hygiene by cleaning your dental appliance regularly and attending follow-up appointments as recommended can help prevent complications.

In rare cases, individuals with underlying oral health conditions or allergies to certain dental materials may be at a slightly higher risk of experiencing complications during a rebase. It's crucial to communicate any relevant medical information to your dental provider before undergoing the procedure to mitigate potential risks.

Overall, while there are minimal risks associated with a rebase procedure, being informed about the potential complications and following post-procedure care instructions can contribute to a smoother and more successful outcome. Your dental professional is there to address any concerns or issues that may arise and ensure that your dental appliance fits comfortably and functions effectively.

How should I care for my dental appliance after a rebase?

After undergoing a rebase procedure for your dental appliance, it's crucial to care for it properly to ensure its longevity and your oral health. Here are some essential post-rebase care tips:

  1. Practice Good Oral Hygiene: Maintaining excellent oral hygiene is essential for the health of your natural teeth and your dental appliance. Brush your teeth at least twice a day using a soft-bristled toothbrush and fluoride toothpaste. Make sure to clean your dental appliance thoroughly as well to remove any food particles or plaque buildup.

  2. Rinse Your Mouth: After eating, it's a good idea to rinse your mouth with water to remove any food debris that could potentially get stuck in your appliance. This simple step can help prevent decay and maintain the cleanliness of your appliance.

  3. Avoid Certain Foods: Some foods may be too hard, sticky, or chewy and could damage your dental appliance. Try to steer clear of foods like hard candies, sticky caramel, or tough meats that could potentially dislodge or break your appliance.

  4. Regular Dental Check-ups: Even after a rebase, it's essential to visit your dentist regularly for check-ups and cleanings. Your dentist can ensure that your dental appliance fits correctly, make any necessary adjustments, and check for any signs of damage or wear.

  5. Use a Denture Cleaner: If you have removable dental appliances like dentures, it's essential to clean them daily using a denture cleaner. Avoid using regular toothpaste, as it can be too abrasive and damage your appliance.

  6. Handle with Care: When handling your dental appliance, be gentle to avoid accidentally bending or breaking it. Always handle it over a soft surface like a towel or a basin of water to prevent damage if you drop it.

  7. Store Properly: When you're not wearing your dental appliance, store it in a clean container filled with water or a denture cleaning solution to keep it moist and prevent it from drying out or warping.

  8. Follow Dentist's Instructions: Your dentist will provide you with specific care instructions tailored to your dental appliance and your oral health needs. It's crucial to follow their advice closely to ensure the best outcomes and prolong the lifespan of your appliance.

By following these post-rebase care tips and staying diligent with your oral hygiene routine, you can maintain the health and function of your dental appliance, keeping your smile healthy and bright for years to come.

Is a rebase covered by my dental insurance?

When it comes to dental insurance coverage for a rebase procedure, the extent of coverage can vary depending on your specific insurance plan.

Typically, dental insurance plans provide coverage for basic dental procedures such as cleanings, fillings, and routine check-ups. However, coverage for more specialized procedures like a rebase may differ.

Before undergoing a rebase procedure, it’s essential to check with your dental insurance provider to understand your coverage details. You can do this by contacting your insurance company directly or speaking with the staff at your dental office who can help verify your coverage benefits.

In some cases, a rebase procedure may be covered by dental insurance if it is deemed necessary for the maintenance and proper function of your dental appliance. Insurance companies often consider the medical necessity of the procedure when determining coverage. It’s important to have your dentist or prosthodontist provide documentation and rationale for why a rebase is needed to support your insurance claim.

It’s worth noting that dental insurance plans typically have limitations, exclusions, and waiting periods for certain procedures. It’s essential to review your insurance policy documents or contact your insurance provider to fully understand the terms of your coverage. This will help you avoid any unexpected costs or misunderstandings regarding your benefits for a rebase procedure.

If your dental insurance does not cover the full cost of a rebase procedure, you may be responsible for out-of-pocket expenses. In such cases, you can discuss payment options with your dental office, such as flexible payment plans or financing options, to help manage the cost of the procedure.

Remember that maintaining open communication with both your dental office and insurance provider is key to ensuring clarity on your coverage for a rebase procedure. By being proactive and informed about your insurance benefits, you can make confident decisions about your dental care and financial responsibilities.
