Cast-Based Guided Implant Placement and Prosthetic Rehabilitation of a Single Edentulous Space: Case Report and Systematic Analysis of Surgical Guides Used in Implant Dentistry.

This report discusses a clinical case of prosthetic rehabilitation of a single edentulous space using cast-based guided implant placement, a surgical protocol for correct implant installation. It also provides a rundown of various techniques used and surgical guides available in dental implantology. Correct and preplanned implant positioning and angulation are the adjuncts to a successful implant-supported restoration. Initially, the residual bone available and its quality were the sole factors that determined implant position and angulation. Lately, prosthetically driven implant prostheses have ensured good aesthetics, function, and hygiene maintenance resulting in long-term success. A surgical guide provides adequate information regarding implant placement and also provides an aid for implant placement at the time of surgical procedure depending on the type of guide fabricated. Cast-based surgical guide fabrication is precise, economical, and time saving in achieving accurate positioning of the implant and subsequently prosthesis placement for correct functioning.
