Implication

Randomized trial compares soft-tissue healing with different collagen matrix architectures in a canine model, suggesting architecture impacts integration outcomes.

Key Points

This study aims to evaluate the impact of collagen matrix architecture on soft tissue integration in a canine model.
Created bilateral defects in 23 skeletally mature beagles
Evaluated soft tissue responses to sheet-form (ShCM) and spongy collagen matrices (SpCM) at 4, 8, and 12 weeks postoperatively
Assessed histological parameters including inflammation, healing, and matrix presence.
At 4 weeks, SpCM showed significantly higher inflammation scores (p = 0.013) compared to ShCM.
At 8 weeks, ShCM demonstrated greater resorption (p = 0.003) and better organized collagen layers, while SpCM maintained thick, porous structures with elevated inflammation versus ShCM (p = 0.002) and sham (p = 0.009).
By 12 weeks, both matrices showed improved healing, with similar inflammation levels, indicating architecture influences long-term outcomes.
