Which of the following factors does NOT help to minimize micromotions during immediate loading?

High primary stability is crucial for immediate loading as it ensures that the implant is securely anchored in the bone, minimizing micromotions during the initial healing period. Rigid implant splinting also plays a significant role by connecting multiple implants, which helps distribute occlusal forces evenly and reduces movements of individual implants. Offset implant placement refers to strategically positioning implants to avoid anatomical structures, enhancing stability and minimizing micromotions.

Implant design does contribute to the overall stability and success of an implant; however, it is not directly a factor that addresses the minimization of micromotions during the immediate loading phase. The design may influence how forces are managed and the initial stability of the implant, but the specific methods like achieving high primary stability, using rigid splinting, and specific placement techniques more directly target the issue of micromotions. Thus, while all these factors are important in the context of implant success, they play different roles, and implant design, in this particular context, does not directly help minimize micromotions as effectively as the other options.
