Clinical Performance of Immediately Restored, Surface Modified Two‐Piece Zirconia Implants. A Prospective Case Series

PurposeTo evaluate the short‐term success and survival rates of immediately restored surface modified two‐piece zirconia implants (CL).Material and MethodsA 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.ResultsFive 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.ConclusionsThe presented immediate restoration protocol may be associated with an increased risk for early implant losses.
