• If a tooth extraction occurred several years in the past, or there has been significant bone loss due to inflammatory processes, the residual bone is usually not sufficient to introduce a secure and stable implant screw.

    In such cases, the available bone can be built up in height and width as required. The procedures listed below are available:

Sinus lift

Bone spreading

Bone block transplantation

This is a process applied in the posterior region of the maxilla, which is carried out in cases of insufficient bone height. Here, the maxillary sinus floor is raised by removing mucosa. The cavity obtained by this is filled with a mixture of autogenous bone (chips which are generated by the implant drilling) and bone substitute material. The implant can now be put in place and becomes secure after a six-month healing period. In general, there is no need for extra surgery. Sinus lift and implant placement are carried out during the same procedure.

In cases of jaws that are to narrow, another proven method of bone spreading (or bone splitting) comes into practice. Here, the jaw is split in the middle by means of a bone saw – we use a low-noise, vibrating instrument (Piezosurgery®) – and pushed apart, so that the implant screw can be placed in the space. The remaining cavity is also filled with bone replacement material. Again, there is no need for any additional intervention.

If a static bone is clearly too narrow, a bone graft is removed from the area of the wisdom tooth region (sometimes the chin region) and fixed in the desired location with small screws or nails. The bone block must first be healed safely before the implants are finally placed during a second procedure.
