Dental Questions: Why do I have to wait for my implant crown?

If you have had an implant placed at our office or one of our specialists' offices, chances are you had to wait three to four months for the implant to heal before having a crown placed on it. Conversely, you may know someone who had an implant placed and left the same day with a (temporary) Crown. Why did you have to wait all that time for your crown? The reality is that there are hundreds of approaches to implant placement, and our office uses the most predictable and conservative method possible. 

Dental implants gain their rigidity in the mouth from two primary sources: the physical retention of the implant screw in bone and the growth of new bone around the implant. The screw force that develops immediately as the implant is placed is formally known as primary stability. This type of retention locks the implant and allows the new bone to form around the it, creating a phenomenon known as osseointegration or secondary stability. Osseointegration creates the definitive force that stabilizes the implant crown for daily use. 

Some techniques will rely on primary stability to support a crown on the implant immediately. In these methods, the screw force of the implant is absorbing all the forces of biting or chewing. Any movement or looseness would prevent new bone growth and could lead to implant failure. At Thousand Oaks Family Dentistry, we know a dental implant is a big investment into your future comfort and quality of life. We prefer to use the most predictable implant techniques and wait for secondary stability to develop. Waiting three to four months for your implant to fully heal is a small price to pay for better chances at success!

Dental Implant vs Bridge: Single Tooth Replacement

For most patients missing a single tooth, a fixed (non removable) and natural looking replacement is the number one priority. Historically, dental bridges offered these results by crowning the teeth adjacent to the missing space and "bridging" it with a false tooth. However, the rise of dental implants has created new opportunities to restore missing teeth without needing to modify the neighboring dentition. The best choice for your mouth depends on a number of biological and cosmetic factors. Take a look!

Dental bridges are an excellent way to restore missing teeth without requiring surgery or implant placement. The most obvious drawback is that the adjacent teeth need to be modified to receive crowns to support the bridging tooth. However, if both teeth already have crowns or large fillings, a bridge can seem like a more attractive option. The biggest hesitation towards placing a bridge is when one of the neighboring teeth is completely healthy and free of any previous dental work. From a oral hygiene standpoint, bridging two teeth creates a potential food trap and an area that is difficult to floss. You will probably need to use floss threaders to clean under and around this area. Cosmetics are difficult to judge on bridges. The height of remaining soft tissue, space to be covered by the false tooth and angulation of adjacent teeth will all influence the final outcome. 

Likewise, implants allow dentists to restore missing teeth independently of neighboring teeth. In fact, an implant does not even need a tooth on both sides of it to be placed. This is why implants are the first choice for replacement when the last teeth in the dental arch are lost. Since an implant is placed surgically, cosmetics can be managed via bone remodeling and gum grafting. A well placed implant is indistinguishable from natural teeth. However, implants have a long healing time, typically requiring 6+ months from insertion to final crown placement. In the meantime, patients are provided with a temporary denture called a flipper if cosmetics are a concern. Another consideration with implants is bone height and health. There needs to be ample space and width for the implant to be placed without damaging nerves, blood vessels or sinuses. Not every patient will qualify for implant surgery. 

Deciding between an implant or a bridge is ultimately your choice. However, an exam and conversation with your dentist can alleviate concerns and help guide you towards the option that suits your needs best.

Gold Crowns and Fillings

Before the age of modern dental materials, metal played an important role in almost all types of restorations. Many dentists opted to use gold for fillings and crowns for it's durability and ease of use. If you have gold dental work, you may be concerned if it's utility has been surpassed by modern technology. On the contrary, gold still stands as one of the best materials available for dentistry today. Read on to learn how and why gold was (and continues to be) a popular dental material. 

Gold is a very malleable metal with a relatively low melting point and high polishability. These properties make it an ideal material for replacing lost tooth structure. Molten gold readily flows into complicated molds, allowing it to be cast into a variety of shapes- including tooth crowns. Once a crown is cast, it easily polishes to a high shine surface that deflects plaque and has great adaptation to tooth structure. Gold is also highly inert, meaning it will not rust or corrode over time. In dentistry, pure gold is mixed with a variety of other metals to better control the durability, color and resilience of the final product. 

Today, gold is used much less frequently than previous decades. However, it still has its place in restorative dental treatment. Gold can be an ideal material for creating a crown on a tooth when only a minimal amount of tooth structure needs to be removed. However, many modern tooth colored materials have met or surpassed the qualities of gold while providing better esthetics. 

In short, there is absolutely nothing wrong with gold as a dental material. Still, there are many newer materials available that mimic the benefits of gold, but with better cosmetic results.

Case Presentation: Repairing Periodontal Damage

According to a recent study put out by the CDC, about half of American adults are affected by periodontal disease. As this condition progresses, the gums and bones recede away from the teeth, eventually leading to their loss. While deep cleanings and medications can stop the spread of the disease, nothing short of extensive surgery can replace lost bone and gums. 

In today's patient, periodontal disease had left them with three lost mandibular incisors and deficient gum levels. Due to the thin nature of bone at the front of the mandible and damage from disease, there was only enough structure to place one implant. Fortunately, by working with the experts at Opus One Dental Labs we were able to create a beautiful three tooth bridge complete with mock gums. Restorations like this have to be designed very carefully to protect the implant and prevent rotation/unscrewing. The end result looks phenomenal and functions just like natural teeth!
