Resumen
The oronasal fistula repair still represents a challenge to the surgeons, because
the high incidence of recidivation. With the aim of evaluate the in block lyophilized
inorganic bovine bone cancellous (BLIBBC) in the treatment of this disease, an
experiment using 10 adult mongrel dogs weighting between 8 and 17 kilograms was
performed. Each dog had an exodontic procedure of both canine teeth, in order to
produce an oronasal fistula. The surgical procedure realized consisted in two different
surgical steps: the left side defect was repaired right after the defect have been
produced, while the right side defect was repaired seven days after the fistula induction;
both sides were repaired using BLIBBC and covered with gengival flap. The animals
were radiological and clinicaly evaluated every week for 120 days. The material used
was effective in the repair of both fistulas, without rejection or recurrence.
