Objective:
The objective of this study was to investigate the suitability of beagles and Labrador retrievers as animal models for osteotome sinus floor elevation (OSFE) and dental implants in posterior maxilla subjacent to sinus.
Study Design:
Ten beagles and 8 Labrador retrievers were included. Their posterior maxillas subjacent to the sinus were studied by a gross survey, CT scan, and histologic analysis.
Results:
In the posterior maxilla subjacent to sinus, the bone height was significantly higher for Labrador retrievers than for beagles (P < .05). There was no significant difference in sinus size from the coronal section and its location from the sagittal section (P > .05) between Labrador retrievers and beagles.
Conclusions:
As an animal model, the Labrador is more suitable for OSFE and dental implants in posterior maxilla subjacent to sinus. The midpoint of the maxillary fourth premolar is an ideal site for implantation.
