Abstract
Motor-driven hone crest expander-compacter (1) whose geometry and dimensions have been redesigned to optimal values that allow the expander-compacter (1) to bc used for bone expansion or compaction in rear areas of the patient's mouth. The expander-compacter (1) presents a threaded body (3) with a cylindrical threaded area (5) and a conical threaded area (6), where the cylindrical threaded area (5) presents a length smaller than two-thirds the length of the conical threaded area (6), in addition to the fact that the total length of the threaded body (3) is less than 12 mm. The invention also refers to a connector (7) connecting the expander-compacter (1) to a surgical motor, and to an initial burr (11), both of them equally optimised.
Claims12
Bone crest expander-compacter (1), that comprises a head (2) for the connection of a connector capable of being connected to a surgical motor, a threaded body (3) and an apical end (4), where the threaded body (3) comprises a cylindrical threaded area (5) and a conical threaded area (6), characterised in that:
- the length of the cylindrical threaded area (5) is less than two thirds the length of the conical threaded area (6),
- the total length of the threaded body (3) is less than 12 mm.
Connector (7), which on one end presents a connection (8) to a surgical motor and on the other presents a head (9) that can be connected to the head (2) of an expander-compacter (1), where said head (9) presents an inner hollow (10) that receives at least part of the head (2) of the expander-compacter (1), characterised in that:
- the head (9) presents a length of between 4 and 4.7 mm and a diameter of between 4.7 and 5.3 mm,
- the length of the inner hollow (10) is between 3.5 and 4 mm.
Initial burr (11), which on one end presents a connection (12) to a surgical motor, and on the other end presents a cutting tip (13), characterised in that the length of the cutting tip (13) is between 9 and 20 mm.
