Abstract
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.
