Bone augmentation - How does bone augmentation work?

Bone grafting is necessary in cases where one’s own jaw bone is not sufficient for an implant.

Ein Knochenaufbau – auch Augmentation genannt – kann sowohl im Ober- als auch im Unterkiefer durchgeführt werden und sorgt dafür, dass die Zahnimplantate sicher im Kiefer verankert werden können. Meist wird beim Knochenaufbau körpereigener Knochen in oder auf den geschwundenen Kieferknochen angelagert, aufgelagert oder eingelagert.

When is a bone augmentation necessary?

Generally speaking a dental implant should be surrounded by at least 2 mm of bone on all sides. In a lot of cases the bone volume needed to support the dental implant is no longer there once the decision to insert a dental implant is made. This is due to the fact that the body has reduced bone volume in the part of the jaw bone that is no longer needed.

Below you will find explanations of the options for bone augmentation that are available to you at our dental practice in Munich. Small-scale bone transplantations can be performed on outpatients under local anaesthetic or light sedation. More comprehensive bone augmentation, necessitating extraction of bone material from your illiac bone, requires general anaesthetic.

How does bone augmentation in the jaw work?

To be able to fix implants, it may be necessary to perform bone transplants. This video explains how this is done.

Get implants despite having a narrow jaw. This is possible thanks to bone augmentation.

If a patient's jaw is to narrow to be able to support implants, bone augmentation becomes necessary. Learn more about the procedure in this video.

Missing bone volume can be compensated by means of minimal invasive surgery, by filling a small part of the paranasal sinuses with bone material (so-called sinus lift).  This develops a sufficient bone layer for the receiving of dental implants.  The procedure is performed through the oral cavity and leaves no external scars.  There are two types of such procedures, the internal sinus lifting and the external sinus lifting.

Getting implants at our dental practice: What is a sinus lift?

If there is not enough bone to support your implants, a sinus lift usually helps. How does this surgery work?

Procedures ensuring that dental implants are securely kept in place: Bone augmentation in the upper jaw

In this example there is not enough bone material in the patient's upper jaw to be able to support a dental implant. This is why bone augmentation was necessary.

Autogenous bone can be taken sufficiently from different parts of the body, and is very suitable for the restoration of jaw defects. There is no risk of infection for the patient, and therefore the body´s own bone is superior to all other materials. 

Natural bone replacement material can be taken from animal material (bone and connective tissue). The material used is a medical product which is approved by the Federal Institute for Drugs and Medical Device (BfArM).  Natural bone replacement material is suitable for the filling of small jaw defects, or as additional material for mixing with autogenous bone.

Synthetic (artificial) bone replacement material consists of calcium-based ceramics or so-called bioactive glasses.  It is offered as granules, and due to the low stability, it is only used for small jaw defects.

In each separate case, the decision on which material is to be used should be made after the necessary diagnostic procedures (clinical and radiographic examination) have been carried out and explained by your treating dentist. In summary, it can be said that autogenous bone is still the most compatible and predictable method for bone augmentation.
