I. Purposes
Successful osseointegration of implants can be determined by the technique of implant installation. The objective of this study was to compare the implant stability and osseointegration of implants using either a flap or flapless technique.

II. Materials and methods
Six young adult dogs were selected and two mandibular premolars and two molars were extracted from both sides. After 8 weeks of healing, 4 hydroxyapatite surfaced Φ3.7*8mm fixtures (OneQ, Dentis, Daegu, Korea) were implanted using either a flap or flapless technique. Implant stability quotient (ISQ) was measured upon insertion, and at 2 weeks, 4 weeks, and 8 weeks later, using Osstell MentorⓇ. The animals were euthanized at 8 weeks after implant insertion while the implant and surrounding tissue were histologically analyzed.

III. Results
Implants were stable upon insertion for both groups and although implant stability steadily increased for 8 weeks, no statistically significant differences were observed between the surgical protocols.
In histomorphological evaluation, via light microscope, results of bone-implant contact of the implants' upper 1/2 area 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 for both meausrements.

IV. Conclusion
This study showed no significant difference in implant stability as well as osseointegration for implant installation regardless of flap or flapless technique. It is thought that flapless implant surgery is a stable technique that can expect good prognosis.
