Mouth implant

The utility model provides the utility model discloses a mouth implant that oral cavity disappearance tooth restoration was used. Be not in good state to synosteosis face squeezing action plant twisting the income process to current planting body, the extruded bone tissue flow direction is unreasonable, the not quite perfect problem of stress surface of formation. It is the plane to have designed the tip terminal surface, and the contained angle ( alpha ) of its pitch arc section pitch arc string and then and planting body axis is lighter than 45 degrees acute angle, and screw on the planting body is the T type screw of angle of varying, and its little distolateral angle ( beta ) is lighter than big distolateral angle ( gamma ), and this root of thread width (1) is greater than cusp width (m), and this screw (7, 8) become shallow while root of thread width (1) to widen so planting body gradually. Having reached that the extrusion more becomes reasonable to the synosteosis face, to plant the back steadiness better plant twisting the income process, having better self tapping nature when being used for the lower jaw, the upper jaw draws the effect of castering action, completion planting that simultaneously also can be fine when the bone quantity not sufficient during planting of palate be used for on.
