Comparative Study on Osseointegration of Implants After Flap and Flapless Surgery in the Mandible of Dogs
The objective of this study was to compare the implant stability and osseointegration of implants using a flap or flapless technique.Material and Methods:
Mandibular premolars and molars were extracted from both sides in 6 dogs. After 8 weeks, 4 fixtures were implanted using either a flap or flapless technique. Implant stability quotient was measured on insertion and at 2, 4, and 8 weeks later. The animals were killed while the tissues were histologically analyzed.Results:
Implant stability increased for 8 weeks, and no statistically significant differences were observed between the surgical protocols. Bone-implant contact showed 60.27% ± 30.99% for flapless surgery and 59.73% ± 17.12% for flap surgery. And the results of new bone formation area from total area showed 56.07% ± 27.78% for flapless surgery and 57.00% ± 14.66% for flap surgery. There were no statistically significant differences.Conclusion:
This study showed no significant difference in implant stability as well as osseointegration regardless of flap or flapless technique.
