The correct answer indicates that the posterior cantilever in the mandible can extend up to 2.5 times the anterior-posterior (A-P) spread, according to Charles English's guidelines. This concept is vital in dental implantology, as it helps clinicians understand the biomechanical limits when planning for implant-supported prostheses, particularly in cases where a cantilevered design is being considered.

The rationale behind this specific measurement is based on maintaining adequate support and stability for the prosthetic restoration. Exceeding the recommended limits can put undue stress on the implants, leading to potential failure or complications.

Understanding this guideline supports the successful implementation of treatment plans that involve cantilever extensions in mandible rehabilitation, ensuring that the load is distributed evenly and that the prosthetic work remains functional for the patient over the long term.
