When is bone augmentation necessary?
Bone augmentation may be necessary in the upper or lower jaw if the jawbone does not have sufficient volume to anchor a dental implant firmly and long-term.
Bone regeneration - procedure and duration
The exact procedure as well as the duration of a bone augmentation depends on the method used and can therefore vary. The more uncomplicated bone augmentation methods, which usually require only a minor procedure, include bone accumulation, bone spreading, socket preservation and sinus lift. In general, you should allow about 30 - 90 minutes for bone augmentation.

Bone augmentation - Methods
Modern dentistry has a suitable method for every individual situation to build up the jawbone, so that a dental implant can then be firmly and securely anchored.
Bone accumulation is a relatively simple method that aims to widen the jawbone. Synthetic bone replacement material or endogenous bone material is usually used, which is placed in the corresponding treatment area and grows together with the body's own bone substance to compensate for the missing bone volume.
This method is only used when bone augmentation is necessary in the upper jaw, as the upper jaw is softer and, unlike the lower jaw, which consists of very hard bone substance, allows for spreading. With the help of a special technique, the upper jaw bone that is too narrow is split and carefully widened. The artificial implant root can then be inserted into the corresponding gap. Any cavities that may have arisen can be filled with bone replacement material.
This method is used when bone spreading cannot be performed due to lack of bone mass. Bone splitting involves a comparatively high effort and is only used for very thin jaw bones. In bone splitting, the jawbone is first split and additionally spread to make room for the artificial implant root. As with bone spreading, any cavities that are created are filled with bone. However, the healing time here takes several months in order to anchor the implant securely and in the long term.
The aim of this method is to preserve the tooth socket of an extracted tooth in order to avoid the bone loss associated with tooth loss. The bone cavity that was previously filled by the original tooth is now filled with a collagen cone. Collagen is formed during the first phase of wound healing itself. This helps to preserve the alveolar ridge for later implantation. This procedure ensures the preservation of the alveolar ridge and optimally prepares the tooth gap for the insertion of an implant.
Bone regeneration (osteogenesis)
In osteogenesis, the jaw bone is split at the intended location in a surgical procedure. A so-called bone distractor is then inserted at both parts of the jawbone, which pulls the two pieces of bone apart in a controlled manner. This artificially created bone fracture activates the natural healing process and stimulates the formation of the tooth bone. However, the formation of new bone structure takes some time until the required bone volume is reached and the insertion of an implant is possible.
A sinus lift (also called sinus floor elevation) is used when the posterior region of the upper jaw does not have sufficient bone volume. To increase the bone height, the floor of the maxillary sinus is raised. The resulting cavity is filled with synthetic or endogenous bone replacement material.
Bone augmentation - pain
During bone augmentation, we use a local anaesthetic to ensure that you feel no pain of any kind. At the patient's request, the operation can also be performed in twilight sleep or under general anaesthesia. After bone augmentation, swelling can occur in the mouth area due to the high blood circulation. However, pain caused by bone augmentation is minor and can be controlled with simple painkillers. Depending on the extent of bone augmentation, the body needs about two to seven days to carry out the appropriate healing process. However, please contact our Seehofer Dental Practice if you experience unusually severe and persistent pain in order to rule out inflammation. Regular cooling should help to reduce slight pain and swelling as much as possible.
Dental implants without bone augmentation
In our dental practice Seehofer we offer our patients modern possibilities for fixed third teeth, which do not require bone augmentation. The All-on-4 concept is an extremely uncomplicated and cost-effective method of achieving fixed third teeth, especially for toothless patients.
