CEREC and The Primescan Up Close – Ann’s Story

By: Dr. Elizabeth Eggert

It is always ideal when your dental exam reveals no problems, but sometimes issues do arise.  If your tooth has a large cavity, cracks, or is broken, Dr. Elizabeth or Dr. Jeff will likely recommend a crown to help restore the integrity of your tooth.  A crown will reinforce the tooth and help keep it functioning for eating, smiling, and speaking.

Crowns have been around for decades and fortunately the materials and process for making crowns has continued to evolve and improve.  Traditionally, getting a crown on your tooth involved two appointments.  Currently, technology exists that allows us to make crowns in our dental office in one appointment.  This offers a number of advantages, probably the biggest of which is convenience in coming to the office for only one appointment instead of two.  Another advantage is the ability to take a digital impression with an intraoral scanner.  This eliminates the need to take a traditional impression with putty material that sets up in your mouth.  A crown in one day also means there is no need for a temporary crown.  Temporaries are durable but do occasionally break or come loose, necessitating a visit to have a new temporary made or recemented.  An additional remarkable feature of the “same-day crown” is the ability to replicate the shape and anatomy of an existing tooth or crown, which makes it easy for your new crown to fit well into your bite.

We have been using this technology with the CEREC system for many years and we recently upgraded our intraoral scanner to the Sirona Primescan, which makes taking digital impressions even faster and easier.  Not every case can be completed in one visit, but many can, which most people find preferable.  A recent patient, Ann, commented, “It is very convenient to get the crown fitted and designed in one visit versus having to come back!”

We want to share some photos with you of Ann’s case so you can see this technology in action.  If one of your teeth ends up needing a crown, you can trust that our great team at Eggert Family Dentistry will take wonderful care of you too!

What Are the Types of Dental Fillings, and What Are the Differences?

By: Dr. Elizabeth Eggert

The earliest dental fillings date back between 6,000 and 10,000 years ago. Since the first fillings were created, dental fillings have been used to help millions of people preserve their teeth. 

What Are of Dental Fillings Made of? 

Dental fillings can be made from a combination of materials, including metal, plastic, glass, and other materials. The most common types of dental fillings are:

  • Composite fillings: Composite fillings – also called filled resins – are a combination of plastic, glass or quartz fillers and can be colored to match the surrounding teeth. They bond to the existing tooth to provide extra support, and they don’t require as much of the tooth to be removed. Composite fillings hold up well, often at least 5 to 10 years, often longer!
  • Amalgam fillings: “Silver” fillings, are really amalgam fillings, and are made of a mix of metals including mercury.  Many people have had amalgam fillings hold up at least 10 to 15 years in their mouths, but  in order to make space to hold the filling, amalgam fillings require more of the natural tooth to be removed and therefore, the overall tooth strength is decreased. Amalgams are generally not requested today because of their unsightly nature. 
  • Gold: Gold fillings can last a long time, often 15 to 20 years. Gold was a more popular choice before composite fillings were available. In today’s market, however, the cost of gold has made it impractical to use this material, not to mention the need for 2 appointments to complete a the filling. 
  • Ceramic: Ceramic or porcelain fillings often last more than 15 years, and they are more resistant to staining than the composite resin materials. With our CEREC restoration system, a ceramic filling can be completed in one appointment. 
  • Glass ionomer: Glass ionomer is a combination of acrylic and glass. It is typically used for fillings below the gum line or for fillings on kids. This material releases fluoride so it can help prevent further tooth decay. Glass ionomer usually lasts less than five years, but it a lot more moisture tolerant during placement so it can be a great material for certain situations. 

Is It Time to Replace Your Dental Fillings? 

Like all dental work, dental fillings need to be revisited and replaced with time. When you visit Eggert Family Dentistry, Dr. Elizabeth or Dr. Jeff can help determine whether it’s time to replace your fillings. 

If you think it may be time to replace a dental filling, call our office at 651-482-8412 to schedule an appointment.

Crown Restorations Made in One Visit Using Our CEREC System

By: Dr. Elizabeth Eggert

Traditionally, if you went to the dentist for a crown restoration, the process would be spread across two appointments. During the first appointment, the tooth is prepared for the crown. This includes re-shaping the tooth to receive the crown and removing the damaged portion of the tooth. Depending on the amount of damage the tooth sustained, it may also require a core buildup. 

After that, an impression of the tooth is taken and sent to a dental lab, where the customized crown is created. You would leave the first appointment with a temporary crown on your tooth. 

Usually after two weeks, you would return for your customized crown. Your temporary is removed and the new crown evaluated for a good fit and cemented. 

Can a Crown Be Fabricated in One Visit? 

At Eggert Family Dentistry, crown restorations can happen in a single visit using the CEREC crown restoration system! 

CEREC stands for Chairside Economical Restoration of Esthetic Ceramics. The system uses computer-aided design – also called CAD – to create permanent customized dental restorations immediately. While it used to take a dental lab a couple of weeks to create a crown, Dr. Elizabeth and Dr. Jeff use the latest technology – the CEREC crown restoration system – to create crowns in minutes. 

In a single visit, we can create a variety of perfectly fitting restorations, including:

  • Crowns
  • Inlays
  • Onlays

Using the Prime Scan to Capture Perfect 3D Images of Your Teeth

We are happy to now be using the latest scanning unit for our CEREC crowns. The CEREC Prime Scan is a recently developed scanning unit that captures highly detailed images of your mouth. 

Many of you had the opportunity to benefit from our previous scanning unit, the Omnicam, and it worked well, but the new CEREC Prime Scan can image even faster and with more detail. With the CEREC Prime Scan, Dr. Elizabeth and Dr. Jeff use a small handheld camera to scan your mouth for crisp, perfectly captured images of your teeth. 

Material Options for Crowns

After taking a scan of your teeth, we’re able to create a crown restoration in minutes. New crowns can be made of compressed porcelain, emax porcelain, or compressed composite resin. During your appointment, you can talk with Dr. Elizbeth and Dr. Jeff to determine what material is the best fit for you. 

Schedule an Appointment to Get Your Crown Restoration in One Visit

In the past, people procrastinated getting their recommended crown restorations for a variety of reasons. They were too busy to come in for multiple appointments. They had a bad experience with a temporary crown. Or they thought the process of getting impressions taken was uncomfortable. 

With the CEREC crown restoration system, that’s all a thing of the past. 

Dr. Elizabeth and Dr. Jeff Eggert of Eggert Family Dentistry can complete the dental restoration work you need in a single appointment. Call our office at 651-482-8412 to schedule your appointment. 

 

What Is a Core Buildup, and Why Would You Need One?

By: Dr. Elizabeth Eggert

When a tooth is severely damaged – for example, from a large cavity, a fracture, or a failed filling – a crown may be necessary to restore the function and appearance of the tooth. However, if too much of the tooth is missing to support the crown, it may be necessary to rebuild part of the tooth. 

A core buildup can be part of the process of preparing a tooth to receive a crown. For the crown to be successful, there are minimum size requirements for the height, width, and taper of a tooth. A core buildup ensures the tooth has a strong foundation and is stable enough to support the crown. 

Is a Core Buildup Always Necessary for a Crown? 

If a tooth has not suffered significant damage, Dr. Elizabeth or Dr. Jeff can often prepare the tooth for a crown without doing a core buildup. However, if the tooth is badly damaged, for example because of a fracture or an existing large filling, a core buildup is an essential part of the preparation for a new crown.

What Is a Core Buildup Made Of? 

Dr. Elizabeth and Dr. Jeff usually use a composite resin or a resin modified glass ionomer to create the core buildup. Although metal-based materials have been used in the past for core buildups, they require a more invasive preparation of the tooth enamel and require an additional appointment to give the material time to fully set. By using a resin material, more of the original tooth can be saved because of the ability to bond to the tooth, which tends to result in better crown retention. Also, the material can be prepared right away and on the same day! 

What Is a Post, and When Is It Needed?

When a substantial amount of the original tooth is missing and the tooth has had a root canal, Dr. Elizabeth or Dr. Jeff may need to add a post to help hold the resin material of the core buildup. The ability to use the root canal space allows for even more support for the new foundation. 

Is the Core Buildup Done at the Same Appointment as the Crown? 

Completing a core buildup typically takes about 5-10 minutes. If placement of a post is needed, the appointment may take longer. When the core buildup is finished, Dr. Elizabeth or Dr. Jeff can use the CEREC crown restoration system to create your new crown in minutes. 

If you think you may need a crown, call our office at 651-482-8412. During your oral exam, Dr. Elizabeth or Dr. Jeff will determine whether you need a crown and a core buildup.

Restoring Teeth with Implants: When Infections Cause the Need for Creativity. Judy’s Story.

By: Dr. Elizabeth Eggert

How did this start?

Judy came to her regular 6-month recare appointment and mentioned that she thought one of her front teeth was turning darker.  Joanna, our hygienist, noticed an issue right away as it looked as if Judy may be developing an infection near that upper front tooth.  Joanna took an x-ray and Dr. Elizabeth did some tests and it was evident that Judy had lost a lot of bone near the roots of some upper front teeth. For an unknown reason (likely a trauma that occurred long ago), Judy’s teeth had started dying, creating an infection and bone loss.  Dr. Elizabeth referred Judy to the root canal specialist and Dr. Aguirre confirmed the extent of the damage with a 3-D x-ray.  Dr. Aguirre agreed that the lesion was excessively large.  He was not confident that root canals alone could clear the infection so recommended that Judy work with an oral surgeon to remove the teeth, the infection, place a bone graft, and hopefully implant(s).

Because Judy didn’t remember any past trauma to her teeth and because of the extent of the bone loss could render all traditional treatment options unpredictable, Dr. Elizabeth recommended Judy undergo the records process to determine all her options going forward.

What did Judy want?

Judy wanted to be able to have front teeth and she wanted to be able to predictably clear her infection.  She agreed to go through the records process to learn about her options and hopefully determine if her current bite could be part of the reason for the trauma that caused her infection.  It was also important to Judy to be able to eat and speak normally after her teeth were restored.  She met with Dr. Wade, an oral surgeon, who agreed that two teeth should come out.  He was fairly confident that the infection was confined to only two teeth.  He noted a large bone graft would be needed for Judy and implants would not be able to be placed until the graft was fully integrated.  He recommended Judy have a temporary denture made to replace her teeth for awhile.

What was involved?

At the records appointment, Dr. Elizabeth took photos and x-rays of Judy’s teeth and did a thorough muscle and joint evaluation.  She used the information gathered at that appointment to develop possible treatment options for Judy.  It was evident after the bite analysis of the records process that Judy has an anterior open bite, which means that her upper and lower front teeth don’t meet up with each other.  This concerned Dr. Elizabeth the most because it meant that Judy’s bite may not adjust well to change, but we knew Judy would undergo a change because of the infection.  There was also a risk that her other two front teeth (or possibly more) could eventually become infected so any plan for Judy had to allow for flexibility in the future.  Dr. Elizabeth presented Judy with multiple options, including implant-based options, a tooth-based bridge option, or a long-term removable partial denture.  In the end, Judy’s treatment choice could have been limited by what would be discovered during surgery, but Judy wanted to restore the missing teeth with one implant that would hold two teeth (better for gum esthetics) and she wanted to repair her bite to make her upper and lower front teeth touch.  This would help with long-term functionality and predictability.

Judy had 2 teeth extracted, the infection removed, and a large bone graft placed by Dr. Wade.  Dr. Elizabeth had a temporary partial denture ready to insert after surgery.  In addition, Dr. Elizabeth built up the edges of Judy’s other front teeth to mimic what her final restorations would look like.

Once the bone graft was integrated, Dr. Wade went back for another surgery to place an implant for Judy.  One implant was placed that would eventually hold and replace two teeth.  After three additional months of healing, Dr. Wade placed a customized healing abutment to help shape the tissue for the eventual tooth restorations.  Judy continued to wear her temporary partial denture during this time.  Dr. Elizabeth also wanted to influence the tissue at the site for her “other tooth” so she built up Judy’s temporary partial denture to put pressure on the tissue and shape it so it would eventually look like a tooth is emerging from the tissue.

During the healing time, Judy also decided she wanted to lighten the color of her teeth so she underwent the Zoom bleaching procedure and improved her shade to 5 times brighter!  Finally, Judy did the final planning with Dr. Elizabeth, completing a lab wax-up, like a blue print, for her future restorations.  When the surgeon gave the “all-clear,” Dr. Elizabeth prepared Judy’s remaining upper front teeth and got impressions of the implant site so 5 restorations could be fabricated for her 6 front teeth.

What does Judy think?

Judy had a long treatment process.  She notes she learned a lot as a lot went into the decision making.  Judy notes “I didn’t have a choice, it was something that had to be done.  It was interesting to learn more about my bite and what it would mean to have longer teeth in the end.”

Judy notes she thinks her teeth look “very nice” and is happy to be done with everything.  “It was a bigger procedure than I expected, but it turned out nice in the end!”

We’re so grateful to have you as a patient, Judy – thank you for putting your trust in us!  It was a pleasure to be able to use our creative thinking skills to help you through this interesting case.

Implants Versus Dentures

By: Dr. Elizabeth Eggert

Thanks to modern dentistry, loss of a tooth – or many teeth – doesn’t have to be permanent. With a small investment of time, money and skilled expertise, it’s possible to replace teeth with implants or dentures.

When our patients are facing the loss of one or more teeth, they come to us for counseling on the best path forward. We consider it part of our customer care to walk them through the options and make sure they understand the pros and cons of each option. Dr. Elizabeth and Dr. Jeff love helping our patients understand the best choice for their individual circumstances. Here’s a quick summary as a starting point.

Implants: The Pros

The best part about implants: They feel and behave like your original teeth. You care for them in a similar way, so you likely don’t need to embrace any fresh routines or invite any new bottles or tubes into your bathroom cabinet. They will prevent neighboring teeth from migrating, so they preserve your bite. Because they are anchored in the bone, they help preserve bone mass in the jaw, Once they are established, they nearly take care of themselves. The feel of chewing, the nuances of speaking, the sensation when you run your tongue along the inside of your mouth – these will all feel completely familiar. Implants are built to last a lifetime, and they almost always do.

Implants: The Cons

Dental implants can take awhile from start to finish. Typically, it’s about six months between initial surgery and final placement of the abutment and crown. There is usually some healing time of the implant which will continue to leave you toothless for awhile. If, however, the missing tooth is in the front of the mouth, we can place a temporary tooth for cosmetic reasons. Depending on your situation, implants may cost more than other options.

Dentures: The Pros

Dentures can be crafted and placed in a shorter time period than implants. They don’t usually require surgery, but sometimes bone recontouring can be necessary to get the denture to fit just right. The initial cost of dentures is lower than most implant replacement options; however, they may need to be replaced as the shape of the jaw, mouth and adjacent teeth change over time, so in the long run may end up costing more.

Dentures: The Cons

Dentures will never feel like your natural teeth. They must be removed for cleaning, and because they can trap food, cleaning is extra important. Denture wearers may have to forgo some of their old eating habits such as corn on the cob. Because they don’t help preserve bone mass in the jaw, denture wearers are likely to experience ongoing jaw bone deterioration, which may prevent them from being a candidate for implants at a later time. Subsequent bone loss may contribute to a sunken appearance of the lower cheeks.

We hope this summary helps you understand your options. We look forward to evaluating your personal situation, and helping you embark on the tooth restoration program that fits your needs. Call us today at 651-482-8412 for your exam and consultation!
