The main aim of this article was to study a case report of the placement of 8single piece basal implants (BCS-Basal cortical screw) in an atrophic maxillary area with flapless technique using CBCT guided stent. All the Basal implants were immediately loaded. Basal implants rehabilitate the edentulous maxillary and mandibular arches when conventional implants cannot solve the purpose, especially in moderate to severely atrophic maxillary and edentulous mandibular arches without any extensive ridge augmentation procedures. In the upper and lower jaws, basal implants are used to support single and multiple-unit restorations. They can be inserted into extraction sockets as well as healed bone. The modern basal implant has been modified into a comparatively simple design, easy to follow surgical protocol, and is a prosthetic-friendly system. Their structural features enable them to be placed in bone that is deficient in both height and width. Basal implantology overcomes all of the issues that come with conventional (crestal) implantology.
