Device - instrumental Surgical dentistry for maxillary sinus floor elevation for Traumatic Force controlled technique

摘要

The Invention is a device for Surgical dental maxillary sinus floor elevation for Technical - traumatic Force controlled.The device contains two metal parts; the first is the insert made of surgical Stainless Steel Bone Anchorage, or similar material, Cylindrical in shape, with an internal thread at the upper part and an external thread at the Bottom, Hollow in all its extension.Because he must travel through the screw Bolt Fracture; and the second is the Bolt Fracture Surgical thread made from Stainless Steel or similar material, in the form of Solid Cylinder,A Section of contact and interaction with the insert of Skeletal Anchorage has a threaded Section at the top and at the bottom has a semi spherical termination that exerts pressure on the Crest of the upper jaw.Insert the Bolt fracture and Bone Anchoring Screw for their joint actions allow you to have full control of the force to implement as maxillary sinus within the Force on the Bolt generates a pressure concentrated in a particular area that the CR Fracture The maxillary Bone,This is because the diameter of the screw Bolt Fracture has Tolerance with the diameter of the hole of the insert Anchor Bone allowing the controlled Movement of the first through the latter.
