Dental implant integration is dependent on osteogenesis driven by the transcription factor SATB2, which regulates osteogenic genes. MicroRNAs (miRNAs) modulate SATB2 and influence bone formation. This review evaluates miRNA-SATB2 interactions, non-coding RNAs, and biomaterials in dental implant osseointegration.
A critical review of studies from 2015 to 2025 was conducted to elucidate miRNA-SATB2 interactions and their impact on osteogenesis.
Inhibitory miRNAs (e.g., miR-31, miR-140-5p) suppress SATB2 via the Wnt/β-catenin or SIRT1/Smad3 pathways and reduce osteoblast differentiation. Promoter miRNAs (e.g., miR-17-5p, miR-27a-5p) enhance SATB2 through BMP/Smad signaling. Non-coding RNAs (e.g., lncRNA H19, hsa_circ_0007292) inhibit miRNAs affecting cancellous bone and promote osteogenesis. Biomaterials such as collagen/nanohydroxyapatite (Col/nHA) scaffolds and comorbidities (e.g., osteoporosis) influence outcomes. Inconsistent miRNA roles and limited in vivo data are key gaps.
miRNA- SATB2 interactions are critical for implant success. Patient-specific miRNA profiling and targeted therapies hold promise, pending clinical validation.
