1. What is a dental bridge?
A dental bridge is a type of restoration A fixed bridge is used to replace one or more missing teeth. It consists of one or more false teeth that are attached to surrounding healthy teeth (called abutments) to fill the space left by the missing teeth. A dental bridge not only restores chewing function, but also improves aesthetics and prevents other dental problems such as tooth shifting.
2. Advantages and disadvantages of dental bridges
Advantage:
- Restore chewing function and aesthetics
- Prevent tooth movement and bite problems
- Improve speech and chewing ability
- Shorter treatment time compared to implant placement
Disadvantages:
- Need to grind healthy abutment teeth
- Can cause plaque buildup and tooth decay if not cleaned properly
- Limited lifespan compared to implants
- May need replacement after a while.
3. Who can get dental bridges?
Dental bridges are suitable for people who:
- Loss of one or more adjacent teeth
- Have healthy and strong abutment teeth
- Unwilling or unable to have implants for health or financial reasons
- Have healthy jaw bones and gums.
4. Types of dental bridges
4.1. Traditional dental bridge
Traditional bridges consist of one or more false teeth that are attached to ground-down abutment teeth. This is the most common type and is suitable when there are teeth on both sides of the gap.
4.2. Dental bridge with (Dental bridge pass)
A cantilever bridge is attached to only one abutment tooth. This type is often used when there is only one abutment tooth next to the gap.
4.3. Maryland Bridges
Maryland bridges use a metal or porcelain framework that is bonded to the back of the abutment teeth, preserving more tooth structure. Suitable for front teeth and small molars.
4.4. Dental bridge on implant
Dental implant bridges use implants as pillars instead of natural teeth. This is the most durable and long-term solution.
4.5. Composite dental bridge
Composite bridges use fiber reinforcement (such as Ribbond) or are bonded with composite. This is a temporary solution or for special cases.
5. How are dental bridges made?
The dental bridge process involves many detailed and precise steps to ensure the bridge fits properly and is durable. Here are the main steps in the process:
5.1. Preparation of abutment teeth
- Examination and treatment planning: The dentist will examine the patient's oral health and decide whether a dental bridge is the right solution. A detailed treatment plan will then be drawn up.
- Grinding down the abutment teeth: The abutment teeth (the teeth that will hold the bridge) need to be ground down to make room for the bridge. This process is done under anesthesia to ensure the patient does not feel any pain.
5.2. Take dental impressions
There are two main methods for taking dental impressions:
- Traditional method: Using impression material such as polyether or vinyl polysiloxane to create a mold of the tooth and surrounding soft tissue. This process can be time consuming and prone to errors due to material deformation.
- Digital method: Uses an intraoral scanner to create 3D images of teeth and soft tissues. This method is faster and more accurate, reducing errors and saving time.
5.3. Bridge fabrication
Based on the impressions taken, the bridge is fabricated in a laboratory. There are two main methods:
- Traditional method: Uses manual techniques to create molds and cast dental bridges from metal or porcelain.
- Digital method: Using CAD/CAM (computer-aided design and manufacturing) technology to create dental bridges from materials such as zirconia or porcelain. This process includes digital scanning, computer design, and CNC machining.
5.4. Test and adjust
- Try-in: After the bridge is fabricated, the patient will try it on to ensure it fits and is comfortable. The dentist will check the bite, fit, and aesthetics of the bridge.
- Adjustments: If necessary, your dentist will adjust the bridge to ensure a perfect fit before cementing it into place.
5.5. Permanent dental bridge attachment
After testing and adjustment, the bridge will be permanently attached to the abutment teeth with specialized dental glue. This process requires precision to ensure the bridge is durable and does not cause discomfort to the patient.
5.6. Inspection and care instructions
- Final Check: The dentist will do a final check to make sure the bridge is securely attached and is not causing any problems for the patient.
- Care Instructions: Patients will be given instructions on how to care for their dental bridge, including oral hygiene and a schedule of regular check-ups to check the condition of the bridge.
6. Care after dental bridge installation
- Clean teeth thoroughly, especially under the bridge.
- Use dental floss and interdental brushes to clean
- Avoid hard, sticky foods that can damage the bridge.
- Regular dental check-ups to check the condition of the dental bridge
7. How long does a dental bridge last?
The lifespan of a dental bridge depends on many factors, such as the material used, its location in the mouth, and how it is cared for. On average, a dental bridge can last anywhere from 5 to 15 years. Implant-supported bridges can last even longer, up to 20 years or more, if properly cared for.
