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 resultin g from the extrusion of an impacted canine in a twelve-year-old girl. An ap ical horizontal root resorption of the adjacent lateral incisor was a relat ed condition to this impaction, influencing the choice of treatment The bon e defect, caused by a guided canine extrusion, was restored by an anorganic bovine bone mineral (Bio-Oss(R)). After a one-year follow-up, the lateral incisor responded vital and showed no discoloration; no progress of the res orption was found. Furthermore, by improving the conduction of new bone for mation from the defect walls, the osteoconductive potential of this anorgan ic bovine bone became obvious. This case report illustrates a new indicatio n area for its use in pediatric dentistry.
