case_images: Intra-oral picture of the patient. The yellow arrows indicate a wafer-thin, knife-edge ridge on the right side of the atrophic maxilla.. The blue circle indicates the implant component seen on the second quadrant in regions 24 and 25.

case_images: The intra-oral finding reveals missing teeth on the upper right posterior quadrant starting from regions 14 to 17, along with a knife-edge alveolar ridge and an implant component in relation to regions 24 and 25 (Figure 1).
case_images: Axial view of CBCT. The yellow arrows in the picture indicate the reduced buccolingual width (2.9-3 mm) of the alveolar bone.. CBCT, cone beam computed tomography

case_images: FIG2
case_images: CBCT revealed an overall reduction in buccolingual width, measuring 2.9-3 mm (Figure 2), and height, measuring 6-8 mm, of the right posterior maxillary region (Figure 3), suggestive of right posterior atrophic maxilla with D4 bone density (fine trabecular, Styrofoam posterior maxilla) .
case_images: Coronal view of CBCT. The yellow arrows indicate the reduced height (6-8 mm) of the alveolar ridge.. CBCT, cone beam computed tomography

case_images: CBCT revealed an overall reduction in buccolingual width, measuring 2.9-3 mm (Figure 2), and height, measuring 6-8 mm, of the right posterior maxillary region (Figure 3), suggestive of right posterior atrophic maxilla with D4 bone density (fine trabecular, Styrofoam posterior maxilla) .
case_images: Intra-operative picture. The mucoperiosteal flap is reflected, and the knife-edge alveolar ridge is exposed.

case_images: Initially, we used conventional burs for pilot drilling followed by sequential drilling using Densah burs operating at an rpm of 700 in the counterclockwise direction (Figure 4).
case_images: Postoperative OPG. A three-implant prosthesis was placed with the help of Densah burs on the marked region.. OPG, orthopantomogram
