400 Year Old Dentures

Archaeologists recently unearthed a 400 year old set of dentures from a monastery in Tuscany. The appliance, made from the wearer's lost teeth and gold bands, is the oldest ever discovered of its type. It is thought that the denture was held in place by looping string around four holes in the gold framework. We hope that the string was tight- the wearer couldn't exactly swing by the store for a tube of Poligrip!

Interestingly enough, this ancient denture still shares some features with its modern counterparts. Today we use plastic or porcelain teeth, but removable partial dentures still utilize a metal framework for rigidity. While you won't find a denture held in with strings, many appliances have wire clasps that achieve a similar function. Overall, the similarities are striking, though we much prefer today's offerings!

With the advent of implant dentistry, many patients may think of dentures as ancient history. However, they are still an important and viable option for replacing lost teeth. If you would like to know more about your choices in completing your smile, please give our office a call!

Case Presentation: Implant Crown

The advent of dental implants has made many procedures more predictable with better cosmetic results. Today's patients is a great example of the power of modern implants. They came to us missing two mandibular incisors and enough open space for one replacement tooth. Unlike the maxillary (upper) teeth, asymmetric midlines are much less noticeable on the lower arch. Using previous dental technologies, replacing this tooth would have required modifying the two adjacent teeth and creating a dental bridge. Preparing mandibular incisors for bridges is problematic, as the teeth are already so small that any reduction in size makes them very fragile. Additionally, bridges are harder to maintain than individual teeth and create food/plaque traps. 

For this patient, a single dental implant and crown created a perfect cosmetic solution to their missing incisor. They were fortunate to have enough bone level in that area to support the titanium anchor. Many times the bone around the mandibular incisors is too thin, requiring grafting or negating the possibility of an implant all together. This is why a proper consultation, exam and treatment plan is crucial in preparing for an implant procedure.

Dental Questions: What do I do if my implant crown comes loose?

Do you have a dental implant? Have you ever noticed that the crown feels loose or that you can move it with your tongue? This sensation can be quite alarming and seems as though the entire implant is wiggling out. However, looseness is usually the result of the implant crown coming separated from the actual implant. 

Although there are a few different implant designs, they all include two pieces of metal screwed together. Over time, the forces of biting and chewing can cause these screws to work themselves loose. This is typically a issue on older implant designs, but can affect any generation.

Your best bet in solving this problem is returning to the dentist who placed the implant, or obtaining a record of what type of implant they used. This information is crucial in tightening the crown back down. Tools, hardware and design are not the same between companies and using incompatible components could ruin the implant.

After identifying the type of implant used, the treating dentist will evaluate wether or not the crown can be saved. Dental Implants are comprised of three components: the actual implant, an abutment, and an overlying crown. The abutment is essentially a metal post that the crown is screwed or cemented to. Depending on which part of the implant has failed, the entire crown may need to be removed to tighten everything back up. However, most crowns are savable and only need to be repaired or recemented once the procedure is over.

Dental Questions: Can Any Tooth Be Replaced With An Implant?

Here, you can visualize how important bone space is in placing an implant. 

In theory, an implant could take the place of any tooth position in the mouth under ideal conditions. However, not every tooth will be a good candidate for replacement with an implant. The main limiting factors are space, bone size and bone health. For an implant to function properly, there needs to be enough distance between the adjacent teeth so that it can be placed without damaging the roots (which would necessitate both the implant and the tooth to be removed). Additionally, there needs to be ample bone height for the implant to sit in and integrate. This becomes a particular problem on the upper jaw, where the maxillary sinuses can encroach on potential bone space. Finally, the bone needs to be completely healthy. Patients with bone density disorders, recent infection or a history of taking certain medications may not be eligible for an implant. 

While we can accommodate a number of conditions with special implant shapes and grafting, there are some instances where placing an implant would be unpredictable or dangerous. In any case, a proper examination (with x-rays) is the only way to determine if you are eligible for a dental implant. If you would like to know more about implants, when we can place them and if you are eligible, please call our office!
