Dental implants are small titanium screws that are placed into the upper or lower jawbone to create a permanent new root. After a period of time the implant integrates with the bone and becomes a secure anchor for a replacement tooth, a fixed bridge a removable partial or a complete denture.

Titan is the most frequently used material in implantology. Owing to its surface oxide-coating it’s very stable, it’s surface energy and strain are high: consequently, it’s able to fasten the water, sodium, calcium, chlorine, phosphate etc. molecules, and proteins, to which the protein structures of the bone-tissue can be linked later. The osteointegration can appear, which means the bony fastening of the implantation.

We use different types of implants Pitt-Easy , AlphaBio, Ankylos and NobelBiocare.

Who is a candidate for a dental implant?

If you miss one or more teeth, then you may be a candidate for a dental implant. Dental implants will allow you to smile, speak, and eat with confidence and comfort.

How much time is required to have an implant procedure?

Placement of the implants is a two phase procedure. In the first phase implants are surgically inserted into the jawbone. In the second phase after 2-6 months the implants are uncovered and supplemented with an implant post on which a natural tooth coloured crown is placed over. A single dental implant placement is usually completed in less than an hour as an office procedure with local anesthesia. The implant is then allowed to heal with the bone for a minimum of 3 months. If there is insufficient bone, various bone enhancing procedures can be performed prior to the implant placement. In this case the period of healing is 6 months.

Is the implant ever rejected by the body?

The implant is machined from surgical-grade titanium alloy which is a biocompatible material. However, there is a slight possibility that it will not integrate with bone. If this were to occur, the implant would be replaced with another one. It is highly unlikely that the second implant would not integrate.

How much pain will I experience?

Usually minimal to none. While undergoing treatment, you will receive local anesthesia. You may have mild post-surgical soreness for up to 72 hours.

Will I get any medicines after the operation?

Yes,the patients always get antibiotics, painkiller, antiphlogistic and some mouthwash after the operation.

What will the appearance of my mouth look like during my treatment?

During treatment, your dentist may be able to provide you with a temporary prosthesis that will have the look and feel that you need during this period of healing.

Will my new tooth or teeth look natural?

Depending upon your condition, your new tooth or teeth will ideally look, feel and function like your own. Dental implants currently provide some of the finest restorative results in dentistry.

What happens if there isn’t enough bone for the implantation?

In most cases there is enough bone. If there isn’t then we constact the bone with artifical bone or the patient’s own bone. The time of the healing is longer, it is usually 6 months. This type of operation is the Sinus lift.

What is sinus lifting?

Sinus lift is surgery that adds bone to your upper jaw in the area of your molar and premolar. It’s sometimes called a sinus augmentation. The bone is added between your jaw and the maxillary sinuses, which are on either side of your nose. To make room for the bone, the sinus membrane has to be moved upward, or “lifted.” A sinus lift usually is done by a specialist.

What It’s Used For

A sinus lift is done when there is not enough bone in the upper jaw, or the sinuses are too close to the jaw, for dental implants to be placed. There are several reasons for this:

– Many people who have lost teeth in their upper jaw — particularly the back teeth, or molars — do not have enough bone for implants to be placed. Because of the anatomy of the skull, the back of the upper jaw has less bone than the lower jaw.
– Bone may have been lost because of periodontal (gum) disease.
– Tooth loss may have led to a loss of bone as well. Once teeth are gone, bone begins to be resorbed (absorbed back into the body). If teeth have been missing for a long time, there often is not enough bone left to place implants.
– The maxillary sinus may be too close to the upper jaw for implants to be placed. The shape and the size of this sinus varies from person to person. The sinus also can get larger as you age.

Sinus lifts have become common during the last 15 years as more people get dental implants to replace missing teeth.

You may need X-rays taken before your sinus lift so the dentist can study the anatomy of your jaw and sinus. You also may need a special type of computed tomography (CT) scan. This scan will allow the dentist to accurately measure the height and width of your existing bone and to evaluate the health of your sinus.

How it’s Done

Your surgeon will cut the gum tissue where your back teeth used to be. The tissue is raised, exposing the bone. A small, oval window is opened in the bone. The membrane lining the sinus on the other side of the window separates your sinus from your jaw. This membrane is gently pushed up and away from your jaw.

Granules of bone-graft material are then packed into the space where the sinus was. The amount of bone used will vary, but usually several millimeters of bone is added above the jaw.
Once the bone is in place, the tissue is stitched closed. Your implants will be placed four to nine months later. This allows time for the grafted material to mesh with your bone. The recombinant bone morphogenetic protein is an engineered protein that is now available. It stimulates bone formation without grafting.

Risks

The main risk of a sinus lift is that the sinus membrane could be punctured or torn. If the membrane is torn during the procedure, the surgeon will either stitch the sinus tear or place a patch over it. If the repair is not successful, your surgeon may stop the procedure and give the hole time to heal.
Your dentist can redo the sinus lift once the membrane has healed. This usually takes a few months. A healed membrane tends to be thicker and stronger, which means a second attempt at a sinus lift is likely to be successful. However, other factors also affect success.
Infection is a risk of any surgical procedure. However, this rarely occurs after sinus lifts.
On rare occasions, the existing bone does not integrate with the bony graft material, and the grafted area does not develop a blood supply. If this happens, any implants placed in this area will fail because there is no live bone for them to attach to. If this happens, you can have the sinus lift procedure repeated.
