Do tooth movement modalities have an impact on the intrinsic healing pattern of intrabony defects treated with Geistlich Bio-Oss® and Geistlich Bio-Gide®? A preliminary histological evaluation gives the first answers.1

After the regenerative surgical procedure—consisting of flap elevation, debridement of the root surface, removal of the granulation tissue, filling the defect with Geistlich Bio-Oss® particles, and covering with Geistlich Bio-Gide®—three patients were randomly allocated to three treatment modalities:

  • Patient without orthodontic tooth movement, serving as a control.
  • Patient with orthodontic tooth movement: one tooth tilted toward the periodontal defect applying uprighting movement in combination with tension forces correlated to the defect.
  • Patient with orthodontic tooth movement: one tooth was moved toward the periodontal defect applying pressure forces.

The re-entry procedure was performed at the 9-month endpoint visit, and bony core samples were harvested from the former defect sites with a microtrephine.

The authors conclude

“Following orthodontic tooth movement, increased active resorption of Geistlich Bio-Oss® along with new bone formation was observed, which needs further investigation due to the low sample size of the present study. Nevertheless, Geistlich Bio-Oss® resorption is a unique phenomenon and may be beneficial for patients treated with a combined periodontal orthodontic as it results in the long-term stability of the grafted sites.”
