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.
Every year dentists place over 5 million dental implants for lost teeth, often removing the problem tooth and installing the implant at the same time. But getting a “tooth in a day” depends on a number of health factors, especially whether or not there’s adequate bone available for the implant. Otherwise, the implant’s placement accuracy and success could be compromised.
Bone loss can be a similar problem when a tooth has been missing for a long period of time. If this describes your situation, you may have already lost substantial bone in your jaw. To understand why, we need to know a little about bone’s growth cycle.
When bone cells reach the end of their useful life, they’re absorbed into the body by a process called resorption. New cells then form to take the older cells’ place in a continuous cycle that keeps the bone healthy and strong. Forces generated when we chew travel through the teeth to the bone and help stimulate this growth. But when a tooth is missing, the bone doesn’t receive this stimulus. As a result, the bone may not replace itself at a healthy rate and diminish over time.
In extreme cases, we may need to consider some other dental restoration other than an implant. But if the bone loss isn’t too severe, we may be able to help increase it through bone grafting. We insert safe bone grafting material prepared in a lab directly into the jaw through a minor surgical procedure. The graft then acts like a scaffold for bone cells to form and grow upon. In a few months enough new bone may have formed to support an implant.
Bone grafting can also be used if you’re having a tooth removed to preserve the bone even if you’re not yet ready to obtain an implant. By placing a bone graft immediately after extraction, it’s possible to retain the bone for up to ten years—enough time to decide on your options for permanent restoration.
Whatever your situation, it’s important that you visit us as soon as possible for a complete examination. Afterward we can assess your options and hopefully come up with a treatment strategy that will eventually include smile-transforming dental implants.
Cancer treatment can be an all-out battle with intense side effects for your entire body. One particular area that can suffer is your mouth.
Chemotherapy and radiation target and destroy cancer cells, which can lead to non-cancerous cells caught in the crossfire and also destroyed. The salivary glands in the mouth are prone to such damage, which could greatly impact your ability to ward off dental disease.
Saliva, what salivary glands produce, plays a major role in oral health. The bodily fluid disseminates antibodies throughout the mouth that fight disease-causing bacteria. It also neutralizes acid, which can erode tooth enamel, and helps restore lost minerals to the enamel.
If the salivary glands become damaged, however, they may produce less saliva and create a condition called xerostomia or “dry mouth.” This is a common occurrence for cancer patients, which can rob them of saliva’s benefits and make them more susceptible to tooth decay or periodontal (gum) disease. The end result could be tooth loss.
There are things you and your dentist can do to prevent this. First, have a complete dental checkup before undergoing cancer treatment. If at all possible have any necessary dental work undertaken (with adequate recovery time afterward) before beginning chemo or radiation. Your dentist and oncologist (cancer specialist) may need to coordinate any planned dental work.
You should also practice daily oral hygiene with brushing and flossing, along with keeping up your regular dental cleanings. This will prevent the buildup on teeth of bacterial plaque, which in turn will reduce your chances for dental disease. Your dentist may also prescribe antibacterial as well as fluoride mouth rinses to help limit the growth of oral bacteria.
To minimize dry mouth, increase your water consumption as much as possible. You may also use saliva boosters like xylitol, an alcohol-based sweetener found in many gums or mints that promotes salivation (it also deters oral bacterial growth).
And don’t forget to maintain a healthy diet, which will not only benefit your stamina during cancer treatment but can also help you maintain better dental health. Providing good care for your mouth during this trying time will help ensure your teeth and gums stay as healthy as possible.
