A clinical case series of three patients is presented using a novel implant design to not only address primary stability but also to prevent damage to the labial bone plate and improve the interdental space for papillae preservation with immediate tooth replacement therapy. This unique implant design features an apicocoronal inverted body-shift in diameter (wide to narrow), shape (tapered to cylindrical), thread depth (deep to shallow), and thread pattern (V-shaped to square) to achieve uncompromised primary stability and esthetics, particularly in extraction sockets, in a singular body form. In addition, the implant possesses a prosthetic angle correction within the implant body to facilitate screw-retention of the restoration and avoid the risk of apical socket perforation.
