The “magic” behind a dental implant’s durability is the special affinity its imbedded titanium post has with bone. Over time bone grows and attaches to the titanium surface to produce a strong and secure hold.
But there’s one important prerequisite for ultimate implant success—there must be an adequate amount of bone available initially to properly position the post during implantation. Otherwise, the implant may not have enough support to position it properly or cover the implant surface completely with bone.
Inadequate bone can be a problem for patients who lost teeth some time before and now desire to an implant restoration. This happens because when teeth are missing, so are the forces they generate during chewing. These forces stimulate new bone growth around the tooth root to replace older, dissolved bone at a healthy rate. If that replacement rate is too slow, the volume and density of bone may gradually diminish.
There is a way, though, to build up the bone for future implantation. Known as bone preservation procedure or a ridge augmentation, it’s a surgical procedure in which the dentist adds bone grafting material to the extraction socket or the bony ridge. The graft serves as a scaffold for new bone cells to grow and multiply. If successful, there will be enough new bone volume after several months of healing to support proper implant placement.
Bone grafting can add more time to the implant process. It may also mean you will not be able to undergo immediate crown placement after implantation (a “tooth in one day” procedure). Instead we would probably suture gum tissue over the implant to protect it and allow for full integration with the bone over a few more months. In the meantime, though, we could fit you with a temporary restoration like a removable partial denture (RPD) or a bonded bridge to improve the appearance of the space while the bone continues to heal.
After several months, your implant will have a better chance of a secure hold and we can then attach a life-like crown. Even if you’ve suffered bone loss, you’ll then have the benefit of not only a durable implant but also a new smile.
Porcelain veneers have become a popular way to transform a smile. They're ideal for stained, chipped or slightly misaligned teeth. But although they don't need as much tooth preparation as crowns or other bridgework, the traditional veneer still requires some permanent tooth alteration.
Now, there's an alternative: no-prep veneers. With this option we can avoid any tooth structure removal or keep it to a minimum. And it may not even require local anesthesia while applying them.
Veneers are as their name implies: a wafer-thin layer of tooth-colored porcelain that's bonded to the outside of a tooth, much like siding on a house. Although the traditional veneer is usually no more than a millimeter in width, they can still add an unnatural bulky look and feel to a tooth. To compensate, we remove portions of the enamel. A tooth permanently altered this way will henceforth require some form of restoration.
No-prep veneers are much thinner; they also don't extend under the gum line like traditional veneers. At the most the new veneers may only require us to perform some minor reshaping of the enamel, but not to the extent of traditional veneers. And because your tooth isn't permanently altered, we could presumably remove the veneer and return the tooth to its natural state and appearance (although removing the bonding might not be that easy).
There are some situations where some tooth alteration may still be necessary, like oversized or forward-jutting teeth. A bad bite (malocclusion) may require orthodontic treatment first — which in some cases could be an alternative treatment to veneers altogether.
