Objective: Purpose of this study is to compare the degree of osseointegration and marginal bone resoprtion in submerged and nonsubmerged
Materials and methods: 14 healthy adult patients with loss of unilateral 1st, 2nd mandibular molars are treated with each of 14
submerged, non-submerged implants. One oromaxillofacial surgeon and one prosthetic doctor each conduct a surgery and
prosthetic treatment. Prosthesis was inserted 3months after surgery. ISQ values was measured by osstel mentor at right after, 1
month after, 2 months after, 2.5months after, 3months after, 4months after and 6months after surgery. In the same period, marginal
alveolar bone loss was measured by paralleling periapical radiography.
Result: There were no case of failure in both two patient`s groups. One month after surgery values of ISQ had decreased and at
once increased gradually again. Amounts of marginal bone resorption tended to increase in over time. There was no significant
difference between two groups in values of ISQ and amount of marginal bone loss.
Conclusion: After implantation of fixture, in aspects of the surrounding tissue healing and osseointegration has no significant
correlation with one-stage and two-stage surgical procedure. [THE JOURNAL OF THE KOREAN ACADEMY OF IMPLANT
