Histologic Evaluation of Human Intrabony Periodontal Defects Treated with Deproteinized Bovine Bone Mineral in Combination with Orthodontic Tooth Movement: A Case Series.

The aim of this case series was the histologic evaluation of guided tissue regeneration utilizing deproteinized bovine bone mineral (DBBM) when regenerative surgery was combined with (test) or without (control) early orthodontic tooth movement. Core biopsy samples were harvested from previously defected sites after 9 months. The histologic section showed integration of DBBM particles in newly formed bone in the apical and middle thirds of the defect, while in the coronal part, graft materials were mainly embedded in connective tissues in the control patient. DBBM particles showed partial resorption with more de novo bone formation in test samples.
