Achieving primary stability is a critical challenge presented by immediate implant therapy. Surgeons often utilize wider, tapered implants for this purpose, or they use longer implants to achieve primary stability. Both strategies are associated with negative ramifications. Prosthetically guided implant placement must respect biologic principles, such as tooth-implant and implant-implant distance, gap space between the implant and the facial cortex, and, when possible, screw-retention of the prosthesis. A novel implant design geared toward achieving a predictable level of primary stability while adhering to the aforementioned physiologic principles was recently introduced. Both primary and secondary implant stability, along with hard and soft tissue stability, are demonstrated in this study of 107 consecutively placed implants. Rotational and axial stability can be produced with this newly designed implant, along with predictable osseointegration and tissue preservation.
