Comparison of Clinical and Radiographic Outcomes Between Single Symphyseal and Parasymphyseal Implants Versus Two Implant-Assisted Complete Mandibular Overdentures

Using two implants to retain mandibular overdentures is the first choice due to their higher masticatory efficiency than a single implant. However, a single implant may be a viable treatment alternative, especially in cases where there are any limitations that restrict the use of additional implants.
