Clinical Case Report

Immediate Loading of an Anterior Implant with a Prefabricated Crown

Adam Hamilton, André De Souza, Simon Doliveux

A fully digital workflow for a patient with adequate bone but soft tissue defects is outlined in this case. Key features include: Use of the CAD software’s mirroring feature to create the digital diagnostic wax-up, a CAD/CAM custom zirconia abutment and PMMA provisional crown, connective-tissue grafting performed at the time of implant placement, and modification of the provisional crown to shape the emergence profile and change the position of the labial mucosal margin to better match the contralateral tooth.

  • * General SAC assessment modifiers that are also part of the ERA. To avoid redundancy they are listed in this section even if no complete ERA has been made.

  • ** Not applicable to the ERA of immediate placement cases and replaced by "Socket Integrity" listed below under "Surgical SAC Classification". For all other placement types this value is a classification determinant and listed here even if no complete ERA has been made.
