Clinical performance of immediately placed and restored progressive-type implants in the esthetic zone: a prospective observational study

PURPOSE: To assess implant success and survival of immediately placed and restored progressive-type implants in the esthetic zone. MATERIAL AND METHODS: A total of n = 21 patients (21 implants) had received an immediate placement of a tapered, two-part implant with a progressive thread design (PL) for a single tooth replacement in the anterior maxilla. An immediate ‘non full-functional loaded’ restoration was provided upon adequate primary stability on a final patient-specific abutment (one abutment-one time concept). The final restoration was provided at 12 weeks (baseline). Implant survival and success (e.g. bleeding on probing—BOP, probing pocket depth—PD, mucosal recession—MR, pink esthetic score—PES) as well as patient- reported outcomes (PROM`S) were recorded at 6 and 12 months. RESULTS: An adequate primary implant stability (i.e. insertion torque > 35 Ncm) was obtained at all but one sites. At 12 months, implant survival (n = 20 patients) amounted to 100%. Non-significant changes to baseline were noted for mean BOP (2.5 ± 28.2%), PD (− 0.26 ± 0.73 mm), and MR (0.0 ± 0.4 mm) values. PES values amounted to 12.9 ± 1.14 and 13.2 ± 0.84 at 6 and 12 months. Technical and mechanical complications were not observed. Patients expressed an overall high satisfaction. CONCLUSIONS: The presented immediacy protocol was associated with high survival and success rates on the short-term. GRAPHICAL ABSTRACT: [Image: see text]
