Abstract
A system of transfer of a simulated position of a dental implant from an X-ray scanner to a robot for drilling a cradle of reproduction, in complementary shape, of a dental casting. The system includes at least one mechanical support and means adapted to removably connecting in a reproducible position the cradle to the support, the cradle containing at least two rectilinear non-concurrent elements visible by X-rays.
Claims10
A cradle (1) adapted for assisting in the placement of a dental implant comprising;
- a cradle with an external contour;
- a lateral protrusion (2) extending from said external contour of said cradle;
- at least two hollow rectilinear non-concurrent tubes (3, 4) disposed in said lateral protrusion (2), said at least two tubes emerging from at least one side of the protrusion and locatable by X-rays.
A mechanical support (10) for a cradle (1) adapted for assisting in the placement of a dental implant, said support comprising:
- an open housing (14) for receiving a lateral protrusion (2) extending from an external contour of the cradle, said housing including openings (15, 16;
- 17, 18) adapted for receiving the ends of at least two hollow rectilinear non-concurrent tubes (3, 4) of cradle, wherein the respective axes of the openings of the support define at least two rectilinear non-concurrent lines.
A system for transferring a simulated position of a dental implant from an X-ray scanner to a robot for drilling a cradle (1) produced in a complementary shape of a dental casting (22), including:
- at least one mechanical support (10) comprising an open housing (14) for receiving a lateral protrusion extending from an external contour of the cradle;
- said support including openings (15, 16;
- 17, 18), adapted for receiving the ends of at least two hollow rectilinear non-concurrent tubes (3, 4) locatable by X-rays, at least two tubes emerging from at least one side of said lateral protrusion wherein the respective axes of the openings of the support define at least two rectilinear non-concurrent lines;
- and
- means (3, 4, 19) adapted for removably connecting the cradle (1) to the support (10) in a reproducible position.
A method for dental implant positioning comprising the steps of:
- positioning at least two rectilinear non-concurrent elements (3, 4) visible with X-rays in an open housing (14) of a first mechanical support (10);
- forming a cradle (1) based on a dental casting (22) and on the mechanical support (10), to integrate said elements (3, 4) in the cradle (1);
- placing the cradle (1), removed from the support (10), in a mouth, and performing scanner tomographic cross-sections of the cradle and of the corresponding jaw;
- determining with a simulation software the optimal position of at least one implant to be performed;
- determining in a referential associated with the rectilinear elements (3, 4), ideal drilling axes by the analysis of the scanner images;
- positioning the cradle (1) in a second support (10), identical to the first support and linked to a robot system;
- drilling the cradle (1) along said axes with the drilling robot of the robot system;
- and
- placing the cradle (1) back into the mouth and using the cradle as a jaw drilling guide for the placing of implants.
