Bone augmentation for dental implants

There may not be enough bone for an implantation due to various reasons. In this case, bone augmentation must be performed before implantation. The most common solution for bone augmentation is the so-called augmentation method. With bone augmentation, artificial or the patient's own bone material is implanted in the desired location in the upper or lower jaw. The additional, new bone material grows together with the existing jawbone and forms new bone substance. An improved, sufficient anchorage for a dental implant is now possible again.

Another option is bone transplantation

Bone augmentation through autografting has the advantage that the material is naturally tolerated by the body, but the disadvantage that the removal is additionally stressful due to the additional operation as well as the defect and pain in the original bone and sometimes even requires an inpatient hospital stay.
This is why, if possible, artificial bone material is inserted with the implant in one operation. This way, both can heal in only one healing phase.

Easier is the implantation of bone replacement material to build up bone. This can be of very different origins. Materials from animal bones, certain types of algae or artificial materials are suitable. These tissues are completely replaced by the body's own bone tissue during the healing phase and are particularly suitable for only minor bone deficits.

Jawbone spreading or distraction osteogenesis are also suitable for bone augmentation prior to implantation. In both cases, the bone is separated by surgery. This stimulates the formation of new bone. In this way, additional bone is gained. The process is very similar to natural bone formation when broken bones heal. In distraction osteogenesis, a device is incorporated to build up bone by stretching the bone a little bit each day. This creates a thickening that makes room for an implant again.

Sinus lift

The sinus lift is almost always performed in the upper jaw. A method of bone augmentation. By lifting the mucous membrane of the jawbone into the maxillary sinus with implantation of bone or replacement bone at the intended location of the implants. This provides adequate support. BMP (Bone Morphogenetic Proteins)

An abbreviation of Bone Morphogenetic Proteins (These are special proteins that the body produces as messengers for bone formation and bone healing. BMPs are used in medicine to build up bone in the case of defects and to accelerate bone healing processes, e.g. fracture healing or implant healing. Bone substitutes are being tested that are loaded with BMPs in order to achieve faster bone formation in the desired area. Implants are already being tested whose surface is coated with BMP's.

An additional procedure is the use of PNP (platelet rich plasma) for faster wound healing. However, the potential to build new bone is limited.
