Abstract
Objective: To study the osseointegration of dental implants placed with a modified surgical technique
in Beagle dogs and to compare it with the conventional method.
Materials and methods: Dental implants were placed bilaterally in the mandible of Beagle dogs using
the press-fit as well as undersized implant bed preparation technique. Micro computer tomography
(micro-CT) and histometric methods were used to analyze the bone implant contact and bone volume
(BV) around the implants.
Results: The bone-to-implant contact percentage (BIC: expressed as %), first BIC (1st BIC: expressed in
mm), sulcus depth (SD: expressed in mm) and connective tissue thickness (CT: expressed in mm) were
analyzed for both groups. The BIC percentage was significantly higher for the undersized installed
implants (P¼0.0118). Also, a significant difference existed between the undersized and press-fit
installed implants for the first screw thread showing bone contact (P¼0.0145). There were no
significant differences in mucosal response (SD and CT) for both installation procedures. Also, no
significant difference was found in the BV, as measured using micro-CT, between the implants placed
with an undersized technique (59.3 _ 4.6) compared with the press-fit implants (56.6 _ 4.3).
Conclusion: From the observations of the study, it can be concluded that an undersized implant bed
can enhance the implant–bone response.
