Detection Of Bone Deposition On The Surface Of Immediately Removed Or Left Mini-Screw After Canine Retraction (SEM Study)

Abstract

Patient and method: This study was performed over 10 patients, each one received 2 machined titanium mini-screws in the upper arch between the first molar and second premolar for retraction of canine tooth. After retraction of canine the left side was removed (group 1) and the right side was left in place unloaded until treatment finished then removed (group 2) . The two groups were transferred for scanning electron microscopy to analyze the changes happened on the surface regarding bone and ions deposited on the surface.
