Drawing of the tapered, double lead threads implant used in this study. (a) Apical threads, deeper and cutting, favour insertion, and initial stability, whereas squared coronal thread enhances bone condensation. (b) Back-tapered collar provides excellent cortical bone management, improving soft tissue support. (c) Octagonal conical connection (2 mm in depth with 8° cone) that guarantees an excellent seal, reducing the risk of micromovements between the implant and the abutment.
