JDIR Issue (Clinical efficacy of dental implants placement without flap elevation: a systematic review and meta-analysis comparing immediate and early loading protocols)

http://www.jdir.org/journal/view.html?uid=484&vmd=Full

1. Purpose
To compare the clinical outcomes of immediate loading (IL) and early loading (EL) protocols in flapless dental implant placement through a systematic review and meta-analysis.

2. Methods
Following PRISMA guidelines, PubMed, Scopus, EBSCO, and Google Scholar were searched. Randomized controlled trials (RCTs) directly comparing IL and EL in flapless implant placement were included. Primary outcome was implant survival; secondary outcomes were marginal bone loss, complications, and patient satisfaction. RevMan 5.4.1 was used for analysis.

3. Results
Eight RCTs involving 360 patients and 450 implants were analyzed. Implant survival and complication rates showed no significant difference between IL and EL. Marginal bone loss was also comparable (MD: 0.02 mm; p=0.75). ISQ values favored EL slightly (p=0.05). Patient satisfaction tended to favor IL but without statistical significance.

4. Discussion
Both IL and EL yielded stable outcomes in flapless implant placement. With sufficient primary stability (≥40 Ncm), IL may offer greater patient satisfaction without compromising implant success. However, limitations include single-country data (all from Italy), heterogeneous prosthetic designs, and limited long-term evidence.

5. Conclusion
IL and EL protocols in flapless implant placement demonstrate comparable outcomes. IL may enhance patient satisfaction, supporting its role as a reliable treatment option in appropriately selected cases. Further multicenter, long-term studies are needed.
