Abstract

Placing dental implants at the level of the existing bone doesn’t guarantee that the aesthetic and corresponding biological function will be obtained when making the final restoration.

In fact, cases with dental implants must be prosthetically planned, guided, and executed. For this reason, before placing the implants, it is necessary to determine the 3D position of the new teeth and then apply the 3A-2B biological rule.

The dental implant should be placed 3 mm in an apical direction (3A) from the margin of the planned crown to maintain the biological space, and 2 mm of buccal bone should be kept to prevent reabsorption (2B). Its application will determine if the existing bone level is correct, or on the contrary, if it is necessary to add or remove the bone.

This course presents the concept and how to apply it in single or multiple implant cases.

The 3A-2B rule will be applied in a maxillary lateral incisor and a first premolar during the pre-recorded workshop.  After placing the two implants, the immediate provisionalization will be made, and the aesthetic results and the integration between the prosthesis and the biology will be seen.

Learning objectives

  • First, know how to plan single implant cases from the prosthodontist’s perspective
  • Second, understand when it’s necessary to reduce the bone, increase it or not modify it
  • Third, understand the relationship between the planned crown margin, bone, and the biological space
  • Fourth, how to perform the osteotomy when it is a prosthetic indication
  • Fifth, understand the use of the rule in full-arch cases
