ChangesinBoneStructurecanAffectDentureFit

It’s a common problem for denture wearers: after years of a comfortable fit, your dentures now seem to be uncomfortably loose. The reason, though, may have more to do with bone loss than the dentures.

Bone is a living tissue with a life cycle — it forms, it ages, and it eventually dies and dissolves (resorbs). It’s replaced with new bone and the cycle repeats. Additionally, the forces generated when we bite or chew are transmitted from the teeth to the jaw, which helps stimulate new bone growth. When the natural teeth are missing, however, the bone no longer receives this stimulus. Resorbed bone isn’t replaced at a healthy rate, which leads over time to bone loss.

Denture construction can also contribute to bone loss. The denture palate rests for support on the bony ridges that once held the teeth. Over time the compressive forces of the dentures apply damages and reduces the volume of gum tissue and eventually does the same to the bone. Combining all these factors, the reduced gum and bone volume will eventually alter the denture fit.

There are a few alternatives for correcting loose dentures. One is to reline them with new plastic, as either a temporary fix performed during an office visit or a more permanent relining that requires sending your dentures to a dental lab. Depending on the rate of bone loss, a patient could go through several denture relinings to accommodate ongoing changes in the jaw. At some point, though, it may be necessary to create a new set of dentures.

A third alternative that’s becoming increasingly useful is to incorporate dental implants into the denture design. Implants can of course be used to replace individual teeth, but a few strategically placed implants (usually of smaller dimension) can serve as a support platform for a removable denture. This relieves some of the compression force of a traditionally worn denture and can slow bone loss.

If you’re having problems with your denture fit, call us for an appointment. We’ll help you decide on the best alternative to improving the fit and making your dentures more comfortable and secure.

KnowtheRisksandBenefitsforSame-DayToothReplacement

While there’s usually a period of months between implant placement and the permanent crown, a new technique known as same-day tooth replacement installs both the implant and a temporary crown during the same visit. But be advised — it does have its risks and isn’t for everyone.

Successful same-day replacements require special attention during the three phases for implants: the removal (extraction) of the existing tooth; placement of the implant in the bone; and attachment of the crown, the visible tooth, to the implant. The tooth extraction lays the foundation for the entire process; the extraction procedure must be performed carefully to avoid undue damage to the socket. In addition, if infection or disease has compromised the site, an implant may not be possible immediately.

The implant must then be placed in the bone so that it’s stable and immovable. All implants stabilize with time as the bone grows and adheres to them, but we need greater stability for a same-day tooth replacement when an extraction is performed.

Our last consideration is positioning the implant so that the attached crown blends in naturally with the surrounding gum tissue and adjacent teeth. We must place it at the proper depth below the gum tissues so that the crown appears to emerge from them in the proper tooth length.

Taking extra care during all these phases, including the angle of crown attachment, will increase our chances of success. We still run a risk of implant damage or failure, however, from biting forces before the implant fully integrates with the bone. This means avoiding chewy foods and other situations that might increase the force on the implant. We may also use a temporary crown that’s slightly shorter than adjacent teeth so it won’t make full contact with the opposing tooth.

If you’d like to know if you’re a good candidate for a same-day tooth replacement, see us for a detailed examination. After reviewing your needs, we’ll be able to discuss with you the risks and benefits for a new look in one day.

UsingSinusSurgerytoStimulateBoneGrowthforImplants

For a predictable outcome, a dental implant should be placed as soon as the bone and gum tissues following a tooth extraction have healed. But what happens if the tooth has been missing for months or years? You might then run the risk of not having enough bone to properly place an implant.

This can happen because of a disruption in the growth cycle of living bone tissue. As older bone cells dissolve (resorption), new bone develops to take its place. This is a dynamic process, as the amount and exact location of the new growth is in response to changes in the mouth, particularly from forces generated by the teeth as we chew. If, however, this stimulation transmitted to the bone no longer occurs because the tooth is missing, the bone will tend to dissolve over time.

In fact, within the first year after a tooth loss the associated bone can lose as much as a quarter of its normal width. This is why we typically place bone grafting material in an empty socket at the same time as we extract the tooth. This encourages bone growth during the healing period in anticipation of installing a dental implant or a fixed bridge. If, however, the bone has diminished to less than required for a dental implant, we must then use techniques to encourage new bone growth to support a future implant.

One such technique for restoring bone in the back of the upper jaw is to surgically access the area through the maxillary sinus (a membrane-lined air space within the bone structure of the face) positioned just over the jawbone to place grafting material. During surgery performed usually with local anesthesia, the surgeon accesses the sinus cavity, lifts the tissue membrane up from the sinus floor and applies the grafting material on top of the bone. Eventually, the new bone growth will replace the grafting material.

If successful, the new bone growth will be sufficient to support an implant. Thanks to this renewed growth, you’ll soon be able to enjoy better function and a transformed smile provided by your new implant.

ReplacingaBackToothMayHelpYouAvoidFutureDentalProblems

Considering the costs, many people view replacing a back tooth as less important than a more visible front tooth. They’re rarely seen, so who will notice?

You might, eventually. A missing back tooth can set off a chain reaction of problems that can affect your overall dental health. Besides playing an important role in chewing food, back teeth also redistribute most of the chewing force away from the front teeth. Their absence can also affect the bite: adjacent teeth to the missing one will tend to migrate toward the open space, causing them to tip and rotate into an improper position. This can cause an increase in tooth mobility, excessive wear and erosion, and endanger their survival in the long run.

To avoid these and other problems you should consider some form of replacement. Most dentists prefer a dental implant for its life-like appearance and durability, and because its titanium post has a natural affinity with bone. Bone cells will grow around and permanently adhere to the implant, which may stop and even reverse bone loss in some cases.

Implants, though, require a certain amount of bone structure initially to anchor and position properly. If you have inadequate bone and don’t want to bone graft the area, the next best option is a fixed bridge, in which the missing tooth is replaced with an artificial crown known as a pontic. The pontic is fused between two support crowns that are permanently affixed to the natural teeth on either side of the missing tooth (also known as abutments). While fixed bridges restore function and inhibit tooth migration, they require the natural tooth supporting the bridge to be reduced to accommodate the crowns placed on them. This permanently alters them and places them at higher risk for future nerve damage, gum disease and decay.

One final option is a removable partial denture (RPD). Although RPDs restore function and improve appearance, their movement within the mouth may place additional stress on the teeth that hold them in place. This movement over time could damage or loosen them.

We can discuss which option is best for you after a complete dental exam. The important thing, though, is to replace the back tooth as soon as possible — doing nothing could cost you much more in the long run.

Dental ImplantsDiscover all the ways in which dental implants can improve your oral health.

If you’re truly looking for a way to replace your missing teeth and give your smile a serious makeover, then you’ll want to consider how dental implants could benefit your oral health. Dental implants are the only tooth loss replacement solution that offers a myriad of unique benefits that other options don’t. Your Riverview dentist shares the best advantages you’ll receive when you get dental implants.

Preserve and protect the jawbone: One of the biggest advantages to getting dental implants is that you will also gain a healthier mouth. When you experience tooth loss the rest of your smile will begin to shift to accommodate the gap in your smile. This also means that you will begin to lose jawbone density, which will cause your face to shorten and appear sunken in. However, dental implants stop teeth from shifting position and also protect the jawbone, preserve your facial structure and help stimulate new bone cell development.

Regain self-confidence: Do you remember how easy it was to sit down to your favorite meal and enjoy it without having to worry about your teeth? Even dentures can make meal times a bit challenging, as they can slip around while you chew. If you want a replacement tooth that is going to make eating and talking as effortless as when you had a full smile, then dental implants in Riverview are ideal.

Increase your smile’s quality of life: Even if you are only missing one tooth the overall aesthetics of your smile takes a major hit. However, opting for a long-term solution like dental implants can give you a complete and natural smile that no one will be able to tell isn’t yours. You can speak more comfortably, chew easier and smile confidently when you have your dental implant.

Oral care stays the same: You don’t have to worry about treating your dental implant differently from the rest of your smile. In fact, you should treat it exactly as you would your natural teeth; however, you still need to maintain good oral health to ensure that your implants last. This means brushing at least twice a day (but ideally after every meal) and flossing daily.

If you want to find out whether you could benefit from getting dental implants, then schedule a consultation with your Riverview dentist. Let implants give you that perfect smile.
