What are dental implants?

Dental implants replace the root of the tooth. They have a cylindrical shape with a thread, similar to a screw. They are made of titanium alloy and are inserted into a premade hole in the jawbone, precisely made in a specific spot, with an exact angle and depth. From the insertion of the implant in the bone, it stays stable in place  With time, the bone around the implant grows and makes tight contact with the microscopically coarse surface of the implant body.

Can implants be used in every restorative case?

This depends on the condition of the jawbone. The dentist checks if the necessary amount of bone is present with and analysis of the x-ray diagnostics. If the bone is insufficient, an augmentation surgery is first needed.

How long will the implant last?

 

After the implant is surrounded by healthy tissue and the crown is properly fitted, the longevity of the restoration depends on the care and regular check-ups. When all of the recommendations are met, dental implants can last lots of years. Crowns and bridges that are fitted onto implants may need some corrections, similar to regular dental crowns.

How many teeth can be supported by an implant?

 

If there is only one tooth missing, then one implant is needed. When multiple teeth are missing, this does not mean that the same amount of implants as the missing teeth is needed. The exact count of implants needed is strongly individual and can be determined after an analysis by a skilled dentist.

What is the procedure?

 

The treatment usually gets divided into 2 or 3 stages, every stage consisting of multiple visits.

Preoperative stage - before surgery, x-rays are needed. This is needed to obtain information about the bone and to make the best treatment plan. Impressions are also taken.

Surgery - in this stage implants are placed. This is done under local anesthesia. After the preparation of a flap, the implant bed is precisely made in the bone. After the implant placement, the incision gets sutured. Sutures are removed after around a week. After that, usually, implants stay hidden ufer the tissue for at least 3 mounts. After this period, a second smaller surgery takes place to uncover the implant.

Tooth restoration with a crown - this stage consists of several visits. Impressions are taken one more time, checking the fitting of the different parts of the restoration and final assembly.

Is there any risk?

There is a small chance that the implant does not heal properly and thus becomes not usable. This risk is higher in some people with specific risk factors. This is going to be evaluated before surgery.

Implant placement is a surgery procedure, which can lead to discomfort, pain, swelling and bruising. Pain can be controlled with over-the-counter painkillers (for example Paracetamol, Ibuprofen) and usually continues for several days. 

There is a small chance that with time some of the elements of the implant systems get loose or worn out. If this is not taken care of, there is a risk of complications.
