Association of Implant Position and Crown Contour With Tissue Health

Emergence profile and crown contour of implant supported rehabilitation, which is influenced by implant position, is associated with peri-implant health and esthetic outcomes. However, there is no study prospectively explore the association between implant position, emergence profile/crown contour, and dental implant outcomes. Thus, the present study aims to (1) assess the multivariate association between local factors and peri-implant soft-tissue health, inflammation, and microbiome; and (2) to identify patterns/clusters of implant characteristics significantly associated with health or inflammation.

Inclusion Criteria:Patients with a single implant-supported restoration in anterior jaws (premolars to premolars), with adjacent natural teeth, with pre-surgery CBCT and intra-oral scans, and willing to comply with research appointments/schedule.Exclusion Criteria:Pregnancy or intention to become pregnant at any point during the study duration;With any systematic diseases/conditions that are contradictions to dental implant treatment;Inability or unwillingness of individual to give written informed consent.Inability of follow-up according to the protocol.
