영문 초록

A two-stage procedure is ideal for getting a successful osseointegration. But if a one-stage procedure can achieve a similar osseointegration, the one-stage procedure has several advantages. The purpose of this study was to observe the initial bone formation and bone remodeling of open type (nonsubmerged) and closed type (submerged), titanium implants. Eight ITI hollow-screws and eight Branemark fixtures were divided into two groups (submerged and nonsubmerged) and were installed on the lower jaw s of four mongrel dogs. T he animals were sacrificed three months later and bone sections with implants were processed for light microscopic and fluorescent microscopic observation. The results were as follows : 1. There w as no sig nificant difference in bone-to-im plant contact between submerged and nonsubmerged im plants. 2. Smooth surface titanium implants showed more bone-to-implant contact than that of titanium plasma coated implants istologically. 3. Under fluorescent microscopy, the active bone remodeling and new bone formation were observed in the interface zone. 4. Under fluorescent microscopy, submerged and nonsubmerged implants had no difference in bone remodeling pattern, and intramembranous bone formation w as more prominent. 5. The connective tissue fibers orienting perpendicularly toward implant surface were oberved in the neck of implants.
