Objective:
The aim of this study was to investigate whether dental implant exposure to the maxillary sinus cavity increases the risk of maxillary sinus complications.
Study Design:
An implant was placed bilaterally in the maxillary sinus of 8 adult female mongrel dogs in a way that it penetrated the bone and mucous membrane of the maxillary sinus floor to the extent of 2 mm, 4 mm, or 8 mm. The implants were left in place for 6 months.
Results:
Radiographic and histologic examinations did not show any signs of pathologic findings in the maxillary sinus of the 8 dogs.
Conclusion:
This study indicates that implant protrusion into the maxillary sinus cavity is not related to the development of sinus complications in canines.
