Dental implants

Replacement of missing teeth with modern, highly reliable, and guaranteed long-lasting implants.

Basic information

What is a dental implant?

Imagine a dental implant as a hollow cylinder or cone made of titanium alloy that is placed into a hole drilled in the jawbone. It serves to support a dental prosthesis, such as a crown or bridge.

To ensure the placement and subsequent use of an implant are as natural as possible, its shape and loading capacity correspond to that of a healthy tooth. One dental implant can support one crown. In the case of two implants, three to four crowns can be attached by means of a bridge. The amount of time it takes for the bone to heal around an implant varies and depends on the quality of the bone that the implant is placed
in. Osseointegration, i.e., the complete healing of the bone around the implant, usually takes four to six months.

Basic information

When is it time to start thinking about an implant?

From a practical standpoint, it’s a good idea to consider an implant before extraction of a tooth that it would replace. Once a tooth is extracted, the bone tissue beneath it often quickly begins to atrophy.

By placing a dental implant and then loading the surrounding bone by attaching a crown to the implant, atrophy is minimised. That’s why we recommend patients undergo implant placement no more than six months after tooth extraction.

 

Once a dental implant is in place, it’s protected for a period of four to six months, after
which the stability of the implant and degree of osseointegration are assessed.
A dental impression is then taken, and a crown is attached. Some patients may
have a weakened jaw and an insufficient volume of bone in which to place an
implant. In such cases, we recommend increasing the volume of bone by means of
augmentation, which involves the use of either the patient’s own bone tissue or
a pharmaceutically modified bone substitute. Augmentation is commonly performed
during implant placement. Everything is left to heal and consolidate beneath
the sutured mucosa. Augmentation is a highly reliable solution to insufficient
bone volume, and we have a 95% success rate in the acceptance of transplanted
bone by the patient’s body. A healing period of six months is required for the transplanted bone to completely integrate into the patient’s own bone tissue.

Treatment of toothless jaws

There are essentially two options for treating toothless jaws with implants. The first option is a removable denture (so-called hybrid denture), the stability and retention of which are supported by means of anchors, most commonly in the form
of a clip or locators. The second option is a fixed bridge.

The first option for treating toothless jaws is a removable denture (so-called hybrid
denture). This is mainly suitable for patients who would have difficulty
cleaning the neck area of implants in the case of a fixed bridge. The
disadvantage to a hybrid denture is frequent maintenance, which involves
removing the denture from the mouth after each meal for cleaning and rinsing.

The fixed bridge comprises both teeth and artificial gums and is securely anchored to
dental implants in the oral cavity using screws. In the upper jaw, the bridge
is attached to a minimum of six dental implants, in the lower jaw five. Because
the bridge is secured with screws, patients generally experience a more natural
bite in as little as four weeks after fitting.

Examination and treatment

01 Initial consultation

The first step is to meet with the potential implant patient at our clinic. During this initial consultation visit, a careful examination is perfomed of the teeth, gums, and especially the area in which implants should be placed. An X-ray examination is
an absolute necessity.

We then create a treatment plan for the patient complete with pricing and timeline. We always try to ensure that the proposed treatment plan is easily understandable, and
that the benefits and degree of difficulty are clear.

02 Scheduling the procedure

Implant placement can be scheduled during the initial consultation visit, or the patient can take time to think about the treatment plan at home and then schedule the procedure later.

03 Procedure

Placement of a single implant takes approximately 20 to 30 minutes.

For patients who are worried about the procedure, we offer analgosedation, which greatly suppresses feelings of fear and anxiety. Antibiotics are administered according
to individual patient needs and the scope of the procedure. If necessary, we can issue a certificate of incapacity for work.

04 Postoperative care

In more complex cases, we perform follow-up examinations two to three days after the implant placement procedure. Sutures are removed after one to two weeks. The third follow-up
examination usually takes place three to four weeks after the procedure. During the next 12 weeks, the bone heals around the implant.

At this point, the implant has securely fused with the surrounding bone. The mucosa covering the implant is removed, and an implant healing abutment, which projects into
the oral cavity, is attached.

05 Implant impressions

Prior to taking an impression of an implant, the mucosa covering it must first be removed, and in some cases the soft tissues around the implant may require correction. Particularly in the upper front jaw, we correct the shape of the mucosa and the gums to achieve a natural appearance of the crown and the area around it.

Once the implant has been exposed, the mucosa around the neck heals sufficiently within two to three weeks, and an impression of the implant can be taken. Next, a prosthetic pillar (abutment) is attached to the implant together with the crown or bridge.

06 Making the crown or bridge

Making the crown or bridge takes approximately one to two weeks and requires two to three visits to a laboratory or the doctor.

With most bridges, such as those to treat toothless jaws, multiple visits are required,
and preparation of the final prosthesis takes longer.

Dental implant success rate

In very rare cases, specifically one in a hundred, an implant fails. IMPLANTA gives its patients a one-year guarantee on implant osseointegration.

We assess healing after enough time has passed for the implant to become fully integrated into the bone tissue, which generally takes four to six months. To confirm
integration of the implant into the bone tissue, we use an Osstell IDx device
to perform resonance frequency analysis based on contactless electromagnetic
pulses. Once osseointegration has been confirmed, an impression of the implant is
taken, and a crown or bridge is made.

Dental implant care

Once osseointegration is complete, implant failure (separation of the implant from the bone) is highly unlikely.

However, consistent long-term implant care is essential:

regularly clean the teeth with a soft toothbrush, interdental brushes, and superfloss

have at least 2 implant check-ups and 2 dental hygiene procedures per year

abstinence from smoking is necessary for long-term implant stability

implant success requires long-term maintenance of normal blood sugar levels

Bone loss treatment

Using bone substitute

In cases that require placement of an implant where the bone tissue has atrophied, it is often necessary to increase the volume of bone by means of augmentation. This is most common for patients seeking placement of an implant once considerable time has passed following the extraction of a tooth.

In general, the back part of the jaw is prone to vertical bone insufficiency, whereas the front part of the jaw is prone to horizontal bone insufficiency. Increasing bone volume is carried out using the patient’s own bone tissue harvested from the back of the lower jaw, or with a bone substitute. Bone substitutes are made with either a synthetic material similar in structure to natural bone tissue, or with pharmaceutically modified animal bone tissue, from which the organic component has been removed, making it entirely safe for the patient. Both types of bone substitute have been subjected to extensive experimentation and testing, and their reliability has been validated in scientific studies as well as by many satisfied patients throughout the world.

Bone loss treatment

Using patient’s own bone tissue

In certain cases, such as advanced periodontosis and injury, one of the best options for increasing bone volume is the use of the patient’s own bone tissue. We most commonly harvest bone tissue from the back of the lower jaw.

Bone harvested from the lower jaw is superior in quality, and the procedure is very safe. The bone that provides the tissue typically regrows to 70% of its original volume. The process of harvesting bone tissue is comparable to extracting an impacted wisdom tooth. After the procedure, the patient uses a pain reliever with
antibiotics. In the first phase, the harvested bone tissue is secured to the
defective area using titanium screws and pharmaceutically modified bone
substitute. Fixation and consolidation of the bone tissue is usually complete
within six months, after which the titanium screws are removed, and a dental
implant is placed.
