Defecto comunicante

Linking defect

The following 35-year-old male patient with no relevant medical history was referred to us with both maxillary canines impacted and temporary tooth #63 having been weeping for some time following a fistula.
Normally, we could resolve this case by first performing extraction surgery of both canines – the definitive and the temporary, then a second operation for reconstruction of the defect, and a third operation for placement of the implant. This would subject the patient to a greater number of interventions and would treble the time taken for treatment.
We opted to resolve the situation in a single operation. We proceeded to extract the definitive canine, which left an extensive bone defect. Once removed, we detached from the buccal bone where we observed fenestration which left the fistulous tract, and we encountered a linking palate-vestibular-crestal defect.

To resolve this situation, we first placed the implant in its ideal position, emerging through the cingulum, so that our prosthodontist colleague could place screws or cement as he wished.
Once this was done, we proceeded to reconstruct  the defect with a cortical autograft of bone from the retromolar area of the left mandible. We filled in all defects with particulate autologous bone and closed the reconstruction by fixing a laminate graft.
Below, you can view photographs of the whole surgery up to the placement of gum formers, at which point we referred the patient to our dentistry and prosthodontist colleague.
