Abstract
An important aspect of the success criteria for dental implants in the
maxillary anterior area involves the establishment of soft tissue contours with
an intact inter-implant papilla and a gingival outline that is harmonious with
the gingival levels of the adjacent healthy dentition. Recently, the tunnel
technique was introduced to maintain the integrity of the soft tissue as an
alternative approach for horizontal augmentation, ideally used in sites with
2-wall defects or a prominent C-shaped curvature of the alveolar ridge.
The purpose of the present case report is to describe step by step a ridge
augmentation procedure utilizing the tunnel technique in combination with
an allograft block graft for horizontal ridge augmentation, performed in
anterior maxilla.
