## Abstract

This present invention concerns a locating and measuring device of facial anatomical parameters of a human face. It includes in particular a frame intended to be positioned in front of a said face, and a bite yoke mounted on a cross member of the said frame, intended to be inserted into the mouth and bitten onto by a patient. In a manner that is characteristic, the device of the invention also includes means for materialisation and positioning of the incisive line, means for materialisation and positioning of the bi-pupillary line, and means for alignment of the Camper's plane on at least one profile of the face. The device of the invention finds a particular application in the fields of dental and periodontal reconstruction and repair in accordance with the aesthetic harmony of the face.

## Claims

### Claim 1

A locating and measuring device of the anatomical facial parameters of a human face, characterised in that it includes:
a frame intended to be positioned in front of a said face and including at least two uprights, and
a bite yoke that includes a securing rod mounted on a cross-member of the said frame, the said yoke being designed to pivot around the said cross-member and around the axis of the securing rod and being intended to be inserted into the mouth and bitten onto by a patient, and
means for materialisation and positioning of the incisive line, attached to the frame and designed to slide so as to be aligned with the incisive line of a patient, and
means for materialisation and positioning of the bi-pupillary line attached to the frame, perpendicular to the vertical uprights, and designed to slide so as to be aligned with the bi-pupillary line of a patient, and
means for alignment of the Camper's plane on at least one profile of the said face, attached to the said frame, and including at least one rectilinear rod fixed onto at least one of the uprights of the said frame and intended to be placed parallel to the Camper's plane of the patient by pivoting of the frame around the cross-member on which the yoke is mounted.

### Claim 2 (depends on 1)

A device according to claim 1, characterised in that the means for materialisation and positioning of the incisive line, and the means for materialisation and positioning of the bi pupillary line include locking means on the uprights of the said frame in a desired location position.

### Claim 3 (depends on 1)

A locating and measuring device according to claim 1, characterised in that the said bite yoke is fixed onto the lower cross-member of the said frame by means of an articulated connecting piece that includes variable clamping means that at least allow movement and locking of the said yoke in translation and in rotation on the said cross-member and around the axis of its securing rod.

### Claim 4 (depends on 1)

A locating and measuring device according to claim 1, characterised in that the said bite yoke includes recording means that are capable of keeping a trace of the position of the dental surfaces of the patient when he bites onto the yoke.

### Claim 5 (depends on 1)

A locating and measuring device according to claim 1, characterised in that the said bite yoke includes pads for de-occlusion of the jaws when the said yoke is bitten onto by a said patient.

### Claim 6 (depends on 1)

A locating and measuring device according to claim 1, characterised in that the said means for alignment of the Camper's plane form a angle of between 60° and 80° in relation to at least one of the uprights of the said frame.

### Claim 7 (depends on 1)

A locating and measuring device according to claim 1, characterised in that the said means for materialisation and positioning of the incisive line and of the bi-pupillary line respectively include a wire mounted so that it slides on the uprights of the frame, and a transparent ruler mounted in at least one slide on at least one of the uprights of the frame.

### Claim 8 (depends on 1)

A locating and measuring device according to claim 1, characterised in that it also includes a positioning means of the median sagittal axis of the face.

### Claim 9 (depends on 8)

A locating and measuring device according to claim 8, characterised in that the said positioning means of the median sagittal axis of the face is attached to the said means for materialisation and positioning of the bi-pupillary line.

### Claim 10 (depends on 8)

A locating and measuring device according to claim 8, characterised in that the said means for materialisation and positioning of the bi-pupillary line include graduations used to centre the said positioning means of the median sagittal axis in relation to the pupils of the said patient.

### Claim 11 (depends on 1)

A device according to claim 1, characterised in that the device includes a transfer tool of a line parallel to the bi-pupillary line, which is parallel to the ideal incisive line, onto a plaster maxillary model of the patients treated, this transfer tool being designed to be positioned on the positioning means of the Camper's plane.

### Claim 12 (depends on 11)

A device according to claim 11, characterised in that, the transfer tool being positioned on the positioning means of the Camper's plane, it is such that it also allows the transfer of a three-dimensional line onto the front and sides of the model, this line belonging to a plane parallel to the Camper's plane and being parallel to the bi-pupillary line at the front of the model.

### Claim 13 (depends on 11)

A locating and measuring device according to claim 11, characterised in that the said transfer tool includes a plate fitted with a rear opening used for adjustment of the plate around a said plaster maxillary model placed on the yoke of the device, as well as frontal cut-outs used for placement of the said plate up against the uprights of the frame and, perpendicularly to the uprights of the frame, bearing onto the said means for alignment of the Camper's plane.

### Claim 14 (depends on 13)

A locating and measuring device according to claim 13, characterised in that the said plate includes a pivoting or fixed languet or tab equipped with at least one central groove or opening used to trace, onto a said plaster maxillary model, a line representing the median sagittal axis of the face of the patient.

### Claim 15 (depends on 14)

A locating and measuring device according to claim 14, characterised in that the languet or tab is fitted with grooves in the T-shape or a cross, used to trace onto a said plaster maxillary model a line representing the median sagittal axis of the face of the patient, and a line parallel to the bi-pupillary line.
