Abstract:
Deficiencies in the alveolar bone and surrounding gingiva can pose challenges in implant placement within the esthetic zone. This clinical report describes the reconstruction of gingival tissue contours through guided bone regeneration (GBR) in the anterior maxilla during implant placement by using a modified titanium abutment to maintain the osteogenic space adjacent to the gingival margin and implant neck.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
