Abstract
Implant placement in narrowed residual ridges was conventionally difficult, which often caused functional or aesthetic problems in the superstructure.
However, at present, the buccolingual width of the narrowed residual ridge can be restored by the guided bone regeneration method (GBR method), bone grafting, residual ridge enlargement using an osteotome, or the split crest technique using a bone chisel, and predictable bone growth is possible.
Implants can be placed at the optimal site by these methods used alone or in combination. These methods are widely used in clinical practice.
We present 3 cases treated by the split crest technique and discuss this technique and its effects.
