Details and patient eligibility
About
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 reported better implant positioning. However, dynamic navigation's application to immediate implant placement has not been studied, and its exact role is still needed to be investigated further. Besides, implant insertion angle may influence primary stability, which is a prerequisite in achieving osseointegration, while dynamic navigation can precisely control angle and position. Therefore, the investigators designed a randomized controlled clinical trial study to verify the clinical efficacy of dynamic navigation and freehand in immediate implant placement. Patients will then be followed up one year after delivery of the crown to assess additional parameters.

These will include the assessment of soft tissue inflammation, cytokine concentrations, microbiome, stability of the buccal bone plate.
