Study design:
This study is designed as a parallel group randomized controlled trial with an allocation ratio of 1:1.
The (PICO) study design: population will be patients from Jordan University Hospital aged 18 years or older, requiring single tooth replacement (molar or premolar) with dental implants, with sufficient bone volume and controlled oral hygiene. The intervention group will receive immediate loading of early placed implants (within 1 week), while the comparator group will receive conventional loading (after more than 8 weeks). The primary outcome is changes in marginal bone levels, and the secondary outcomes include implant primary osseointegration, stability, patient satisfaction, and various complications.
Both groups will receive early placed implants after 8-12 weeks of healing (Type 2-3A placement). The surgical procedure will follow standardized protocols, with no variations between groups other than the loading time.
Blinded assessors will perform radiographic and clinical evaluations at designated follow-up visits: at implant placement, definitive loading, 6 months, and 1 year. Ethical approval is obtained prior to study commencement, and all participants will provide informed consent.
