The use of anorganic bovine bone to correct a residual osseous defect after tooth extrusion: report of case.

This report deals with the clinical treatment of an osseous defect resulting from the extrusion of an impacted canine in a twelve-year-old girl. An apical horizontal root resorption of the adjacent lateral incisor was a related condition to this impaction, influencing the choice of treatment. The bone defect, caused by a guided canine extrusion, was restored by an anorganic bovine bone mineral (Bio-Oss). After a one-year follow-up, the lateral incisor responded vital and showed no discoloration; no progress of the resorption was found. Furthermore, by improving the conduction of new bone formation from the defect walls, the osteoconductive potential of this anorganic bovine bone became obvious. This case report illustrates a new indication area for its use in pediatric dentistry.
