Assessment of Immediate versus Delayed Loading Protocols in Single Tooth Anterior Implants.

Background: The timing of prosthetic loading plays a critical role in the long-term success of dental implants. In anterior maxillary regions, both functional and aesthetic outcomes are vital, and clinicians often debate between immediate and delayed loading protocols. Methods: A prospective, randomized clinical trial was conducted on 40 patients (20 per group) requiring single anterior maxillary implants. Group A underwent immediate loading within 48 h post-implant placement, while Group B underwent delayed loading after 3 months. Outcomes assessed over 12 months included implant stability (measured by implant stability quotient [ISQ]), marginal bone loss (via cone beam computed tomography), peri-implant soft tissue health, and patient satisfaction (visual analog scale [VAS] scale). Data were analyzed using t-tests and chi-square tests, with P < 0.05 considered significant. Results: At 12 months, implant survival was 100% in both groups. Mean marginal bone loss was 0.73 ± 0.22 mm in Group A and 0.69 ± 0.25 mm in Group B (P = 0.54). Mean ISQ at 12 months was 71.6 ± 3.5 (Group A) vs. 72.1 ± 3.2 (Group B) (P = 0.61). Soft tissue indices were comparable. Group A showed significantly higher early patient satisfaction (VAS 9.2 ± 0.8 vs. 7.4 ± 1.1, P < 0.01), though differences were negligible at 12 months. Conclusion: Both immediate and delayed loading protocols demonstrated comparable clinical and radiographic outcomes. Immediate loading offers superior early patient satisfaction without compromising implant success, suggesting it as a viable option for anterior single-tooth rehabilitation in suitable cases.
