Bone structure for
Implants in the jaw


For the successful, long-lasting use of implants, a good bone supply must be available. Basically, the stronger the bone, the better the grip on the implant. However, if the bone does not meet the necessary requirements, the quality of the jawbone or maxillary sinus can be improved before the actual implantation by various methods of bone structure such as a sinus lift. Effort and costs for individual procedures differ drastically.

Bone degradation in the jawbone is usually caused by paradontitis, tooth loss or the high chewing pressure on the sinus bottom by a denture. Aspects such as genetic factors, general illnesses, medication intake, age and, for example, smoking also affect the extent of degradation.


Prerequisites for the optimal holding of implants are on the one hand the sufficient bone height and, depending on the implant, a sufficient bone width of the jawbone. The reconstruction of the bone width is less problematic than an increase in bone height.

In the lower jaw, there is usually a higher density and bone quality than in the upper jaw, which increases the success of the implantation. In the upper jaw, however, there is often not enough bone of its own due to the arched maxillary sinus to securely anchor a dental implant in it. In this case, a so-called sinus lift can remedy the situation.


A sinus lift is commonly referred to as the surgical thickening or raising of the maxillary sinus base, distinguishing between an external or internal sinus lift. A sinus lift can only be carried out on the upper jaw, whereby in the operative way own bones or bone replacement material is inserted below the maxillary sinus. Thus, a higher bone height is achieved, which now, after a healing phase of approx. 4 months, offers sufficient support for a dental implant.

The external and internal sinus lift differ in that the external sinus lift is the more complex procedure, as it is only used when the existing bone height is very low and several millimeters of bone height has to be obtained. To do this, the maxillary sinus wall must be exposed with the utmost precision and caution in order to then insert the bone material into the cavity between the mucous membrane and the bone.

An internal sinus lift is a minimally invasive operation in which access to the maxillary sinus floor is through the drilling channel of the later implant. The advantage of this is that no second operating area needs to be opened. However, this method also requires patience and high precision, especially since visibility through the borehole is sometimes very limited.


Our jaw and implantology experts will be happy to advise you on whether you need a bone structure, e.g. by means of a sinus lift, before the implant treatment.
