Claim Text:
1. A dental restoration method comprising: dissecting attachment of a tooth to be extracted from soft tissue around the tooth to create a soft tissue socket; extracting the tooth to leave a bone socket and the soft tissue socket; preparing the bone socket for immediately receiving an implant; immediately after preparing the bone socket, fixing the implant into the bone socket; connecting a post to the implant; selecting an immediate soft tissue implant preservation hollow shell that has an outer shape and dimensions that substantially match the soft tissue socket; and placing the shell into the soft tissue socket outwardly of the implant to form a biological seal without gaps with the soft tissue socket, the shell not being connected to the implant so that an outer surface of the shell engages against the soft tissue socket without gaps and without requiring alignment or fixed relative positioning between the shell and the implant, the post extending in the interior volume of the shell with a minimum inside diameter of the shell being larger than a maximum outside diameter of the post so that there is no mechanical connection between the shell and the implant with the outer surface of the shell engaged against the soft tissue socket without gaps and without requiring alignment of the shell axis to the implant axis and with freedom of relative position and angle between the shell and the post.
