Abstract

fetched live from OpenAlex

Osseointegration is controlled by a number of cellular mechanisms. Although factors governing bone formation are well-understood, the maintenance of bone at the bone-implant interface is less clear. Of some interest is the role of osteocytes, which via mechanotransduction are believed to be responsible for mechanical loading-based remodelling events in bone. Using a resin cast etching technique, we investigated the osteocyte lacuno-canalicular network adjacent to nanostructured titanium human dental implants after four years in clinical function. Correlative electron microscopy showed nanoscale osteocyte processes extending directly onto the implant surface. Calcium signal mapping via electron energy loss spectroscopy (EELS) showed apatite ingrowth into the nanotextured surface, while the apatite platelet c -axis was oriented approximately parallel to the collagen fibril direction. Furthermore, Z-contrast electron tomography demonstrated that natural bone-osteocyte and engineered bone-implant interfaces are similar in ultrastructural morphology. The present ultrastructural observation of multiple connections between osteocyte canaliculi and the nanotextured surface oxide suggests that osteocytes contribute toward the maintenance of osseointegration in long-term clinical function.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
