Introduced to the United States in the 1980s, dental implants have quickly become the go-to restoration for tooth replacement. And for good reason: they're not only incredibly life-like, they're highly durable with a 95% success rate.
But as desirable as they are, you may face a major obstacle getting one because of the condition of the bone at your implant site. To position the implant for best appearance and long-term durability, we must have at least 4-5 mm of bone available along the horizontal dimension. Unfortunately, that's not always the case with tooth loss.
This is because bone, like other living tissue, has a growth cycle: Older cells die and dissolve (resorb) and newer cells develop in their place. The forces transmitted to the jaw from the action of chewing help stimulate this resorption and replacement cycle and keep it on track. When a tooth is lost, however, so is this stimulus.
This may result in a slowdown in cell replacement, causing the eventual loss of bone. And it doesn't take long for it to occur after tooth loss—you could lose a quarter of bone width in just the first year, leaving you without enough bone to support an implant. In some cases, it may be necessary to choose another kind of restoration other than implants.
But inadequate bone isn't an automatic disqualifier for implants. It's often possible to regenerate lost bone through a procedure known as bone augmentation, in which we insert a bone graft at the missing tooth site. The graft serves as a scaffold for new bone cells to grow upon, which over time may regenerate enough bone to support an implant.
Even if you've had a missing tooth for some time, implementing bone augmentation could reverse any loss you may have experienced. In fact, it's a common practice among dentists to place a bone graft immediately after a tooth extraction to minimize bone loss, especially if there will be a time lag between extraction and implant surgery.
Bone augmentation could add extra time to the implant process. But if successful, it will make it possible for you to enjoy this popular dental restoration.

A wave of madness is about to sweep across Indianapolis and onto television screens across America—March Madness, that is. That's right: After its cancellation in 2020 due to COVID-19, the famed NCAA men's basketball tournament is back with all 68 games scheduled to be played in and around Indianapolis. As you can imagine, there will be numerous health precautions, and not just for the pandemic—there should also be mouthguards aplenty.
Why mouthguards? Although you might think football and hockey would be rougher on players' teeth, gums and jaws, basketball actually tops the list of sports with the most dental injuries. Such an injury occurring from a split-second contact with another player could take years to overcome.
Fortunately, mouthguards are a proven way to reduce sports-related mouth injuries among professional and amateur basketball athletes. Made of a pliable plastic, mouthguards cushion against blunt forces to the mouth generated during play (and not only formal games—practices and scrimmages too).
But while wearing a mouthguard is a no-brainer, choosing one can be a little intimidating. True, they all work on the same principle, but there are dozens of types, designs and price ranges.
We can, however, distill them down to two basic categories: “boil and bite” and custom mouthguards. You'll find the first kind online or in a local retail sporting goods store. It's named so because you first place it in hot water to soften it, and then place it in the mouth and bite down to create an individual fit.
As an inexpensive option, boil and bite mouthguards provide a level of protection. But they also tend to be bulky and uncomfortable, which can tempt players to wear them less. And the softer plastic (compared to custom guards) allows for a lot of jaw (and in turn, teeth) movement, which can cause teeth to loosen over time.
Custom mouthguards, on the other hand, are created by dentists based on impressions made of the wearer's mouth. As such, the fit tends to be more precise, requiring less material than the boil and bite variety, thus affording a greater degree of comfort. And there's less potentially damaging jaw movement with a custom mouthguard. As you might imagine, custom mouthguards are more expensive, but compared to the potential treatment cost for a sports-related dental injury, it's money well spent.
Investing in a custom mouthguard for your family basketball (or football, hockey or baseball) player is a sound way to protect their dental health. And that's not madness at all.
It's a common practice among people slowly losing their teeth to have their remaining teeth removed. They find dentures to be less costly than replacing one tooth at a time or caring for those that remain. On the other hand, it's usually healthier for the mouth to preserve remaining teeth as long as possible, replacing them only as necessary.
This latter strategy has up to now been difficult and expensive to achieve. But dental implants are changing that—using these imbedded titanium metal devices with a variety of restorations, we're able to better plan and implement staged tooth replacement.
Most people associate implants with single tooth replacements of a life-like crown cemented or screwed into an abutment attached to the implant post. This can play an early role in a staged replacement plan, but at some point, multiple single-tooth implants can become quite expensive.
Implants, however, have a much broader range of use. A few strategically placed implants can support a variety of restorations, including bridges and removable or fixed dentures. Four to eight implants, for example, can secure a fixed denture replacing all teeth on a jaw, far fewer than the number needed to replace the teeth individually.
Implants may also improve the function of traditional restorations. For instance, dentures can't stop the bone loss that often results from tooth loss—in fact, they will accelerate it as they rub and irritate the bony ridges of the jaw. By contrast, implants stimulate bone growth, slowing or even stopping the process of bone loss.
In a traditional bridge, the outer crowns of the restoration are bonded to the teeth on either side of the missing tooth gap (the middle crowns fill the gap). These support teeth must be permanently altered to accommodate the crowns. But an implant-supported bridge doesn't depend on other teeth for support, thus eliminating the need to permanently alter any teeth.
More importantly, previously placed implants often become part of the next stages of tooth replacement, like building on an addition onto an existing house. All in all, including implants in your ongoing dental restoration can help you enjoy the benefits of preserving your natural teeth for much longer.
