How long is a dental implant surgery reliable?
Bone augmentation in the jaw: treatment
The jawbones and gums form an important part of the teeth holding apparatus. At the same time, they absorb a lot of the enormous pressure that occurs when biting. This pressure is also a stimulus: tooth roots transfer it to the jawbone, where it stimulates the formation of bone cells and ensures jaw substance and natural stability. Jawbone regrowth works smoothly in healthy, younger people. From around the age of 35, however, the production of new bone material lags behind the age-related onset of bone loss. In such cases a Bone augmentation become necessary.
Natural bone loss and other dangers for the jawbone
Depending on the age it comes to individually Bone lossVarious factors speed up. After a tooth loss or after wearing a prosthesis for a long time, the jawbone lacks the stimulus for growth from the tooth root and it recedes. In this case, the bone loss is usually too great to provide patients with fixed, implant-supported dentures.
An experienced dentist who has mastered both implantology and maxillofacial surgery is required here. With the bone structure, he first prepares the insertion of the dental implants. Because these are not only aesthetically and functionally similar to real teeth - they also have comparable requirements and require a stable hold in the bone.
More about dental implants
Dental implants can be inserted directly into the jawbone. The actual implant takes on the function of a natural tooth root. After a healing period with a build-up and crown, it grows into a fixed denture in individual teeth, which cannot be distinguished from natural teeth. At the same time, dental implants are able to fix dentures.
The inconvenience of a loose prosthesis will then be a thing of the past. Modern dental implants made of titanium or ceramic show good material properties for these purposes. They are stable, durable and biocompatible. Within a few weeks they become firmly attached to the jaw. To ensure that enough bone cells adhere to the implant for this reliable hold, the dental implant needs a bone substance that is at least two millimeters thick. If there is no natural basis, a specialist in bone augmentation creates this basis artificially.
Bone augmentation, dental implant and costs
Statutory health insurance companies only cover the costs of dental implants in the amount of the fixed allowance for standard care, despite the many advantages of implants over dentures. Patients without appropriate supplementary dental insurance bear additional costs, as well as for bone augmentation, as a personal contribution. This investment in solid, natural-looking dentures is also worthwhile economically. With careful dental care and prophylaxis examinations by the dentist, dental implants offer reliable dentures into old age.

Bone augmentation for implants
If one or more gaps in the row of teeth are to be closed, then dental implants are the best choice. However, the prerequisites for inserting a dental implant are not always met. In some cases, the bone mass is insufficient to ensure adequate support and stability. If there is too little bone mass, the implant will not find a hold and cannot heal properly. Serious complications can result if the bone height and width are insufficient. With the help of the bone structure carried out by an oral surgeon, the bone regains more substance.
When is it necessary to build up the jaw bone?
However, bone augmentation is not always necessary. Often, bone grafting is necessary when one or more gaps between the teeth have not been replaced with a denture for a long period of time. If the bone is not used and stressed, it breaks down. This bone is needed again for the use of an implant. In the context of maxillofacial surgery, bone substitute materials are introduced to which natural bone can attach itself again. As soon as the bone has sufficient mass again, the oral surgeon can insert the implant.
The course of treatment for bone augmentation for implants
Oral surgery knows different methods for Bone augmentation for implants. If an implant only needs a little additional bone mass, the bone is built up at the same time as the implant is placed. Otherwise - also with bone grafting in the lower jaw - bone grafting and implantation result in two treatment appointments spaced apart from the healing time.
Preparations for bone grafting
Before the actual bone augmentation, the bone augmentation specialist takes x-rays of the jaw and carries out a volume tomographic examination. In this way, the MKG specialty practice in Moers determines whether or not bone augmentation is necessary for the implant. Then it is planned how the bone should be built up and which material should be used. After the planning has been completed, the treatment follows.
Course of the bone augmentation treatment
The dentist performs minimally invasive bone augmentation in the upper jaw with a sinus lift. The oral surgeon opens the gums in the area in which the bone grafting implant is to be inserted. This gently lifts the membrane between the upper jaw and the paranasal sinuses. The bone augmentation specialist fills the resulting cavity with bone substitute material, which grows together with the natural bone cells in around nine months. The area is closed again with an artificial membrane and the healing process begins. After the healing time, the implant is placed.
Bone structure in the upper and lower jaw
If a bone in the upper or lower jaw is not stressed, the body breaks it down. Bone loss takes place in both the upper and lower jaw. However, the type of degradation differs. In the upper jaw, the width of the bone initially decreases. Only later does it lose height. In the upper jaw, the bone must therefore be built up both in width and in height.
If lateral bone augmentation has to take place in the upper jaw, this is called a sinus lift. During the sinus lift, a lateral bone window is opened, the membrane between the maxillary and nasal cavities is severed and bone substitute material is introduced into the space that has been created. In the lower jaw, the bone mainly loses height when it is not used. The focus here is on building bone height.
The healing time in bone grafting
At theone-step procedure there is no need to wait between building up the bone and placing the implant. Because: bone formation and the insertion of the implant take place in a single operation. However, the necessary bone structure must not be too large here.
At thetwo-stage process the implant is only inserted when the bone is built up. This can take up to six or nine months. During this time, the body accumulates natural bone material on the bone substitute material that was previously introduced as a framework.
