Prosthetic-driven immediate implant placement for optimal aesthetic restoration has been increasing in demand during the last decades but requires higher accuracy. Dynamic navigation has been a reported better implant positioning. There are two main choices of implant macrogeometry: straight and tapered implants. One feature of implant design that may influence implants' accuracy is the taper of the implant body. However, their exact role is still needed to be investigated further. Besides, implant macrogeometry may influence primary stability, which is a prerequisite in achieving osseointegration. Therefore, we designed a randomized controlled clinical trial study to verify the clinical efficacy of the implant macrogeometry by comparing straight implants with tapered implants in immediate implant placement using dynamic navigation.
