Although dental implants are best known as single tooth replacements, they can actually play a role in multiple or complete tooth loss (edentulism) restorations. While replacing multiple teeth with individual implants is quite expensive, there’s another way to incorporate them in a restoration at much less cost — as supports for bridges.
In this case, only a few strategically placed implants are needed to support restorations of multiple crowns fused together into a single unit. Implant-based bridges consist of two main types: the first type is a fixed bridge, which is permanently attached to the implants and can’t be removed by the patient. It’s often the preferred treatment for patients who’ve lost most or all of their teeth but have not yet experienced significant bone loss in the jaw.
This choice, however, may not be the best option for patients with significant bone loss. In these cases, there’s a second type of fixed bridge: an implant-supported fixed denture. This type of fixed denture provides support for the lost bone support of the lips and cheeks. If a fixed bridge is not possible due to finances or inadequate bone support to place 4 to 6 implants, a removable denture (also known as an overdenture) that’s supported and held in place by implants is the next best alternative. Unlike a fixed bridge, an overdenture can be removed by the patient for cleaning purposes, and will require less investment than a fixed bridge.
For people with bone loss, the overdenture does more than restore chewing and speech function. Because bone loss can diminish support of the facial structures — actually shorten the distance between the chin and the tip of the nose — an overdenture provides additional bulk to support these structures to improve appearance. Depending on what the patient needs for facial support, overdentures for the upper jaw can be designed as “full palates,” meaning the denture plastic completely covers the upper jaw palate, or open in which the plastic doesn’t completely cover the palate.
Besides the condition of your teeth, gums and bone, your own personal preferences and financial ability will also play a role in which option is best for you. After considering all these factors, we can recommend which of these types of implant-based restorations will fit your needs. With either bridge, fixed or removable, you’ll certainly benefit from the improvement to both your mouth function and your smile.

Cardiovascular disease and periodontal (gum) disease are two different conditions with their own set of symptoms and outcomes. But they do share one common element: inflammation. In fact, this otherwise normal defensive response of the body might actually create a link between them.
When tissues become damaged from disease or injury, the body triggers inflammation to isolate them from the rest of the body. This allows these tissues to heal without affecting other tissues. If inflammation becomes chronic, however, it can damage rather than protect the body.
This happens with both cardiovascular disease and gum disease. In the former, low-density lipoproteins (LDL or “bad cholesterol”) in animal fat leave behind remnants that can build up within arteries. This stimulates inflammation of the vessel’s inner linings, which accelerates hardening and increases the risk of heart attack or stroke.
With gum disease, bacteria living in a thin, built-up film of food particles on the teeth called plaque infect the gum tissues, which in turn trigger inflammation. A struggle ensures between the infection and inflammation, causing the gum tissues to weaken and detach from the teeth. Coupled with erosion of the supporting bone, the risk of tooth loss dramatically increases.
Recent research now seems to indicate the inflammatory responses from these two diseases may not occur in isolation. There is evidence that gum inflammation could aggravate inflammation in the cardiovascular system, and vice-versa. The research, though, points to some possible good news: treating inflammation in either disease could have a positive effect on the other.
Making heart-friendly lifestyle changes like losing extra weight (especially around the waist), improving nutrition, and exercising regularly can help reduce LDL and lower the risk of arterial inflammation. Likewise for your gums, daily oral hygiene and visiting the dentist at least twice a year reduces the risk for gum disease. And at the first sign of a gum infection—swollen, reddened or bleeding gums—seeking immediate treatment will stop it and reduce any occurring inflammation.
Taking steps to prevent or reduce inflammation brought on by both of these diseases could improve your health and save your life.

Dental work isn’t performed in a vacuum — the state of your general health can have an impact on procedures and vice-versa. This is especially true if you’re taking certain medications like blood thinners.
Blood thinners such as Warfarin or Clopidogrel are used for a number of medical conditions as an anti-coagulant (inhibiting blood from clotting). They’re commonly part of a stroke or heart attack prevention strategy in patients with cardiovascular disease, or those with tendencies for thrombosis (blood clot formation within blood vessels) or pulmonary embolisms (blood clots within the lungs). They’re also used with patients with artificial heart valves or on a temporary basis with patients who’ve recently undergone knee replacement or similar surgical procedures.
In most cases, dental work won’t be affected by your use of a blood thinner. An issue might arise, however, if an invasive procedure has the potential to cause bleeding, like a tooth extraction or gum surgery. Because the blood doesn’t clot normally it may be difficult to stop the bleeding during such procedures.
To avoid undue complications, it’s always best to let your dentist or oral surgeon know what medications you’re taking, especially blood thinners (this includes low-dose aspirin, a common over-the-counter drug that’s often prescribed as a mild blood thinner). Depending on the procedure and your dosage, they may consult with your prescribing doctor to see if temporarily stopping the medication or reducing the dosage is an acceptable precautionary measure for your dental treatment. Your dentist may also take precautions during the procedure to help reduce bleeding such as using haemostatic agents around the wound site to help stabilize blood clotting, while carefully suturing the wound to avoid disrupting smaller blood vessels (capillaries) that easily bleed.
If your dosage has been temporarily stopped or reduced, you’ll usually be able to resume blood thinners immediately after the dental procedure. Working together, your dentist and doctor will help ensure that your health won’t be at risk and your dental procedure will occur without undue complications.
