In the case presented, the treatment plan was to place a single implant in the aesthetically demanding anterior maxillary region in the place of the left lateral incisor.

A moderate horizontal ridge defect was present and the residual bone width was 5.6 mm. A staged approach employing a guided bone regeneration technique with a porcine partially demineralised cortical lamina (OsteoBiol Soft Cortical Lamina, Tecnoss Dental) was chosen. A porcine bone substitute (OsteoBiol mp3, Tecnoss Dental) was used as a filler material.

After the augmentation procedure, the lamina was covered with a collagen membrane to allow for rapid soft-tissue integration. The augmentation surgery was completed with meticulous flap closure using microsurgical techniques.

After a healing period of six months, an implant of 3.8 mm in diameter and 11 mm in length was placed according to the restorative planning. Finally, an all-ceramic crown was seated on the zirconia abutment.

The images of the final result demonstrate clearly that an aesthetically pleasing outcome was achieved by employing the bone augmentation technique described.
