PURPOSE: To evaluate the short-term success and survival rates of immediately restored surface modified two-piece zirconia implants (CL).
MATERIAL AND METHODS: A total of 23 patients had received CL implants (n = 26) for single-tooth replacements in the anterior and posterior maxilla and mandible at healed extraction sites. Immediate implant restoration was accomplished if an insertion torque ≥ 30 Ncm was reached (Type 3-4 A protocol). Final occlusally screw-retained crowns were provided after 3 months of healing. Implant survival and success (i.e., bleeding on probing-BOP, probing pocket depth-PD, mucosal recession-MR) were assessed at 6 and 12 months following final restoration. Patient-reported outcomes were evaluated at 6 and 12 months.
RESULTS: Five implants (n = 5 patients) could not be immediately restored, and four implants were lost during follow-up. The survival rates amounted to 80%. For the final analysis, 16 patients with a total of 16 implants were evaluated. Minor changes to baseline (final restoration) were noted at 6 and 12 months for mean BOP (-3.3% ± 13.14%; 8.3% ± 16.9%), PD (-0.15 ± 0.48 mm; 0.08 ± 0.48 mm), and MR (0.0 ± 0.0 mm; 0.0 ± 0.0 mm) values. Mechanical and technical complications were not observed. Patients expressed an overall high satisfaction at 6 and 12 months.
CONCLUSIONS: The presented immediate restoration protocol may be associated with an increased risk for early implant losses.
