Dental implants

History

Replacing lost teeth with a bone-anchored device is not a new concept at all. Archeological findings showed that the ancient Egyptian and South American civilizations already experimented with re-implanting lost teeth with hand-shaped ivory or wood substitutes. In the 18th century lost teeth were sometimes replaced with extracted teeth of other human donors. The implantation process was probably somewhat crude and the success rates extremely low due to the strong immune reaction of the receiving individual. Brånemark et al, started the new era of modern implantology in 1969 when they published their first findings about the titanium dental implants the first time. Since that time the shape and surface of the titanium implants have changed. Nevertheless, this method still remains popular and reliable. Nowadays the most popular are root-form dental implants.

What are dental implants?

Dental implants are small titanium fixtures that are placed in the jawbone and bond with the bone to replace the root portion of natural teeth and serve as anchors for crowns, bridges and dentures. Dental implants can be used to replace a single lost tooth or many missing teeth. All dental implants have the same functional requirement: to support chewing forces and deliver them safely and effectively to surrounding interfacial tissues over many years. Dental implants can also be used to attach full or partial dentures..

Why dental implants?

In most cases, anyone healthy enough to have a tooth extracted is a candidate for dental implants. Age is not usually an obstacle. Time is important, however, as the size and thickness of the jawbone begins to decrease once the teeth are lost. This bone shrinkage makes the face look older and is the reason why lower dentures tend to become looser with time. The placement and “loading” of dental implants will halt this loss of bone just as regular exercise helps to prevent osteoporosis. In the past, replacement of missing teeth has been accomplished with fixed bridges or removable dentures.

However, not all people can adjust to partial or complete dentures or have teeth that are strong and healthy enough to support bridges. In addition, healthy tooth structure must often be sacrificed in order to create the supporting portions of a bridge. Dental implants allow each replacement tooth to stand on its own. Implant supported teeth will improve your appearance. They look and feel like your natural teeth. Dental implants can greatly improve the quality of life for complete denture wearers. Either or both of the lower and upper denture can be “locked down” by securing it to a number of implants which have been placed in the jawbone. In some cases, if the patient so desires, all of the missing teeth can actually be replaced with implant supported crowns and bridges.

Am I a candidate for dental implants?

Implants, however, are not an option for everyone. Because implants require surgery, patients must be in good health, have healthy gums, have adequate bone to support the implant and be committed to meticulous oral hygiene and regular dental visits. If you are considering implants, a thorough evaluation by your dentist will help determine if you would be a good candidate.

The success of implantation depends on selection of patients. Absolute contraindications: Cardiovascular problems (hypertension, rheumatic heart disease, etc), uncontrolled diabetes, psychosis – unrealistic expectations, drug and alcohol abuse, kidney dialysis, prepubertal age, leukaemia, immunosuppressive disorders, pregnancy, colagen and bone diseases, liver disease, uncontrolled hypertension, oncological diseases. Require further investigation: Systemic haematological disorders (anemia, granulocytopenia, et cetera), irradiation of jaws (5000 rads or greather), pulmonary problems (asthma, bronchitis, emphysema), anticogulant therapy, psychiatric or psychological disorders, chemotherapy, immunosupression, hemophilia, uncontrolled diabetes, liver and kidney disorders. Oral considerations: Different kind of oral pathology (tumors, cysts, impacted teeth and others), ridge dimensions insufficient to accommodate proper implant placement, lateral oral interferences, solid centric cuspid disclusion, parafunctional habits such as bruxism, nail biting, pencil biting, tobaco use, alcohole abuse, poor oral hygiene.

Surgical dental implant installation requires understanding of associated anatomical structures. Planning should be done on three-dimensional edentulous jaw segment pattern. The KODAK 9000 3D extraoral imaging system enables dental professionals to obtain low-dose, high-resolution three-dimensional images, as well as panoramic images, at an affordable price. This unique “2-in-1” system (3D and panoramic) is well suited for dental professionals who regularly perform complex diagnostic, restorative, surgical, and endodontic procedures.

A very high frequency KODAK 2200 x-ray generator supports superior image quality and better safety conditions for our patients and our staff.

KODAK RVG 6100 Digital Radiography System has the high resolution digital imaging sensor. Due to new technological advances with the optical plate and scintillator, all size sensors have increased “sensitivity,” which allows a practitioner to decrease the radiation dose — up to 10% decrease for sizes 1 & 2 and 40% decrease for size 0.

What is involved in placing implants?

First, surgery is performed to place the anchor. This is carried out under local anaesthetic or sedation. The placement is therefore painless. Surgery can take up to several hours, and up to six months may be required for the bone to grow around the anchor and firmly hold it in place. Some implants require a second surgery in which a post is attached to connect the anchor to the replacement teeth. With other implants, the anchor and post are already attached and are placed at the same time. After the gums have had several weeks to heal, the next step is begun. The artificial teeth are made and fitted to the post portion of the anchor. Because several fittings may be required, this step can take one to two months to complete. If you are having one or more missing teeth replaced with implant supported teeth the complete reconstruction process will take 4 to 9 months. This is because it takes time for your bone to grow around and bond securely to your implants.

Guarantee

The dental implant manufacturer we use (Straumann) have a 10 year guaranty on the implant itself. In a case of failure of dental implant during ossteointegration, money paid for dental implantation will be refund.
