An immediate dental implant shell has outer, multiple zones for engaging a soft tissue socket left immediately after tooth extraction from a bone socket. The zones have combinations of different biologic agents, macro- or micro-geometric, or micro- or macro-morphology irregularities to better engage gingival sulcus, junctional epithelium and dento-gingival fiber zones of the soft tissue socket. The shell may also have various guide markings and projections to aide drilling of the implant hole in the bone socket. A dental implant is placed in the drilled implant hole before or after the shell has been placed in the soft tissue socket, and has an axis that is independent of the shell axis so the shell and implant both sit in optimum positions in their respective soft and bone sockets.

A dental implant arrangement and method has a hollow shell with outer bio-compatible surface for engaging a soft-tissue socket that is 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. A luting compound fills the volume between shell and post and solidifies, thereby connecting shell to post and indirectly to the dental implant with no other connection between the shell and the implant so that the outer surface of the shell engages against the soft-tissue socket without gaps and without requiring alignment between the shell and implant axes.

A dental measurement instrument having a handle and a measuring gauge extending from one end of the handle. In one embodiment, the measuring gauge has at least two calibrated measurement shafts in fixed spatial relationship with each other, each shaft bearing a plurality of calibration indicia. The calibration indicia on the two shafts are correlated with each other in a specific predetermined mathematical relationship.
