Abstract
The two-implant-supported mandibular overdenture is considered a reliable treatment option to restore masticatory function. Digital planning has shown to improve the precision and accuracy of the surgical procedure. The outcomes are indeed pertinent to the ideal 3D positioning of the implant placement. Recently, the use of cone-beam computed tomography (CBCT) and intraoral ccan (IOS) have improved greatly the workflow of digital planning, however, the sophisticated technology caused confusion among the clinicians. The purpose of this case series was to exhibit the efficacy of a bone-supported guide in applying simultaneous implant placement and bone reduction solely based upon CBCT data. The bone reduction can therefore be determined accordingly, by adding windows to the guide, allowing the clinician to decide the amount of bone reduction as well as the location for implant placement. This novel surgical guide would not only fit properly on the bone, but also provide benefits of l ess-invasive surgery and the opportunity to place implants parallel. The digital workflow described not only simplifies the fabrication process, but also yields predictable surgical outcomes.
