A dental implant has a hollow shell with outer bio-compatible surface for engaging a soft tissue socket left in gingival tissue after a tooth has been extracted, to promote healing. The shell tapers outwardly from a first to a second perimeter, the second perimeter being asymmetrically scalloped with opposite distal and mesial peaks and opposite lingual and facial valleys between the peaks. A dental implant in the bone socket left after tooth extraction is rigidly connected to a temporary post, the temporary post extending in the shell. The shell engages against the soft tissue socket without gaps and without requiring alignment between the shell and implant axes.

A process for preparing one of a patient's upper and lower jaw for a full arch teeth replacement may include extracting every tooth in a patient's arch to define a corresponding number of post-extraction root sockets, wherein each tooth is extracted atraumatically to substantially maintain the patient's original alveolar bone and original keratinized gingiva, waiting a period of time to allow for tissue healing and substantial osteoblast/osteoclasts interaction and remodeling such that newly ossifying bone fills space in each of the post-extraction root sockets, installing a plurality of socket-sized implants less than the number of post-extraction root sockets into corresponding post-extraction root sockets, and allowing for osseointegration of each of the socket-sized implants into the newly ossifying bone of the corresponding post-extraction root sockets.

A dental implant for facilitating interdental papilla growth includes an implanted portion configured to be inserted into a jawbone; an abutment configured to be attached to an exposed end of the implanted portion; and supracrestal fibers extending laterally from an exterior surface of the abutment to form a scaffold between the dental implant and an adjacent tooth for facilitating interdental papilla growth in a supracrestal region of the dental implant.

A margin line point picking method and a dental CAD device for the same are disclosed. In a margin line point picking method according to one embodiment, while a user picks a margin line point, a preset optimum margin line point is recommended by showing a preview thereof on a screen. Accordingly, it is possible to address the inconvenience that the user has to find and pick an accurate point.
