It takes respective thickness to matter thickness degree, different according to the first screw thread branch thickness, is strengthened thread bonding strength, ensures in cortex of bone
Layer at least remains with the complete thread of the 3 circle above, and the pitch of first screw thread is 0.2 millimeter to 1 millimeter.
Preferably, for cortex of bone hardness it is higher the characteristics of, cortical layer portion does not dig screwed hole in advance during operation, but
Screwed in by the first screw thread branch self tapping, to ensure that the first screw thread branch closely connects cortical layer, prevent the second screw thread branch
The joint face of the first screw thread branch and sclerotin is destroyed, is more than implant diameter at the first screw thread branch straight at the second screw thread branch
Footpath, the implant should be tapered from top to bottom.
Preferably, the implant outer surface be locally rough surface, rough surface be advantageous to after implant is planted with area of new bone
Matter merges, and to ensure preferable effect, the rough surface is no less than 1/3rd of the joint face.
The implant bottom is provided with locating slot, and locating slot is used to sclerotin agree with after the completion of implant plantation, prevents from planting
Body is rotated or loosened.
Preferably, setting is multiple helps to evenly spread to masticatory force along the equally distributed locating slot of implant bottom outside
On the bone of implant surrounding, implant stability is improved, improves using effect.
