Abstract
Background: The aims of this pilot study were to evaluate the efficacy of treatment consisting of the immediate loading of implants placed immediately after tooth extraction in fullarch restorations and to compare the clinical and radiographic outcomes of implants placed in healed versus postextraction sites in the same group of patients. Methods: Twenty-three patients who needed full-arch restorations were treated. One hundred forty-four implants were placed: 59 after tooth extraction (test group) and 85 in healed sites (control group). Within 48 to 72 hours of implant placement, nine maxillary and 15 mandibular arches received screw-retained fixed prostheses, consisting of a titanium framework fabricated with a computer-aided design and manufacturing techniques and composite resin teeth. The insertion torque for implants was ≥30 Ncm. Implant stability measurements (ISQ) and radiographs of the marginal bone level (MBL) change were performed at prosthesis delivery and after 1 year. Results: One implant in the test group and one implant in the control group failed, giving a cumulative success rate of 98.6%; the prosthesis survival rate was 100%. At the 1-year follow-up, no statistically significant difference was found between the control and test sites with respect to MBL change (0.47 + 0.18 mm versus 0.57 + 0.27 mm) or mean ISQ values (62.24 ± 1.92 versus 61.34 ± 2.15). Conclusion: These preliminary data suggest that immediate loading of implants placed immediately after extraction may be a viable treatment option for edentulous arches when implants are stable at insertion and are rigidly splinted with screw-retained titanium-resin prostheses.
