The restoration of maxillary anterior tooth by implant is difficult that most patients have trouble with chewing, prounciating,
even more aesthetic. Fortunately there are many technological advances in implant surface, so we can get a early
primary stability and second stability. but atrophy is most severe after restoration in the anterior maxilla with the degree
of horizontal/vertical bone/gingival resorption. The highly esthetic zone of the premaxilla often requires both hard (bone
and teeth) and soft tissue restoration. This is the case we performed delayed implant installation with Guided bone generation
(GBR) for the purpose of preventing bone resorption , connective tissue graft to change gingiva from thin biotype
to thick biotype and zirconia abutment and all ceramic crown to prevent gingival recession after restoration. (JOURNAL
