Abstract

fetched live from OpenAlex

BACKGROUND: Bio-Oss is a deproteinized bovine mineral used in bone augmentation procedures. The particles are often mixed with a protein product (Tisseel) to form a mouldable graft material. AIM: The aim of the present experiment was to study the healing of self-contained bone defects after the placement of Bio-Oss particles alone or mixed with Tisseel in cylindrical defects in the edentulous mandibular ridge of dogs. MATERIAL AND METHODS: In 4 labrador dogs, the 2nd, 3rd and 4th mandibular premolars were extracted bilaterally. 3 months later, 3 cylindrical bone defects, 4 mm in diameter and 8 mm in depth, were produced in the right side of the mandible. Following a crestal incision, full thickness flaps were raised and the bone defects were prepared with a trephine drill. The defects were filled with Bio-Oss (Geistlich Biomaterials, Wolhuser, Switzerland) particles alone or mixed with Tisseel (Immuno AG, Vienna, Austria), or left "untreated". A collagen membrane (Bio-Gide, Geistlich Biomaterials, Wolhuser, Switzerland) was placed to cover all defects and the flaps were sutured. 2 months later, the defect preparation and grafting procedures were repeated in the left side of the mandible. After another month, the animals were sacrificed and biopsies obtained from the defect sites. RESULTS: Bio-Oss-treated defects revealed a higher percentage of contact between graft particles and bone tissue than defects treated with Bio-Oss+ Tisseel (15% and 30% at 1 and 3 months versus 0.4% and 8%, respectively). Further, the volume of connective tissue in the Bio-Oss treated defects decreased from the 1 to the 3 month interval (from 44% to 30%). This soft tissue was replaced with newly formed bone. In the Bio-Oss+ Tisseel treated defects, however, the proportion of connective tissue remained unchanged between 1 and 3 months. CONCLUSION: The adjunct of Tisseel may jeopardize the integration of Bio-Oss particles with bone tissue.

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.
