## Abstract

A device (1) for placing a dental splint (2) which is intended to be fixed at the level of the lingual, palatal or vestibular surfaces of at least two adjacent teeth (10) to immobilize the teeth. The placing device (1) has at least one flexible and elongated guiding support (3) carrying the splint (2), at least one positioning element (4, 4′), mounted so as to slide on the guiding support (3) behind the splint (2), and arranged for being positioned substantially in front of an interproximal gap (9) between the at least two adjacent teeth (10). A pressing mechanism (5, 5′) coupled to the positioning element (4, 4′) and arranged to bring the positioning element (4, 4′) close to the at least two adjacent teeth (10) to be interlocked, when pressed, to bring the splint (2) in contact and conform with the lingual, palatal or vestibular surfaces.

## Claims

### Claim 1

A placing device (1) for placing a dental splint (2), the splint being in the form of one of a flexible wire, tape or grid out of a flexible metallic, a synthetic material or a composite material, the splint (2) being intended to be fixed at the level of the lingual, palatal or vestibular surfaces of at least two adjacent teeth (10) in order to immobilize the at least two adjacent teeth (10) with respect to one another,
wherein the placing device (1) comprises at least one flexible and elongated guiding support (3) carrying the splint (2),
at least one positioning element (4, 4′), mounted so as to slide on the guiding support (3) behind the splint (2), and arranged for being positioned substantially in front of an interproximal gap (9) between the at least two adjacent teeth (10),
pressing means (5, 5′) coupled to the positioning element (4, 4′) and arranged to bring the positioning element (4, 4′) close to the at least two adjacent teeth (10) to be interlocked when pressed in order to bring the splint (2) in contact with the lingual, palatal or vestibular surfaces and fit to their shape and
the positioning element (4′) comprises two enlarged end sections (4a, 4b) connected together by a narrow central section (4c) which comprises a slot (4d) for the passage of the splint (2), the positioning element (4′) is arranged to adopt a retracted rest position in which the end sections (4a, 4b) are close to each other and a stretched active position in which the end sections (4a, 4b) are spaced from one another so that the central section (4c) passes in the interproximal gap (9) in order to bring the splint (2) in contact with the lingual, palatal or vestibular surface of the teeth (10).

### Claim 2 (depends on 1)

The device (1) according to claim 1, wherein the positioning element (4′) is made of one single part out of an elastic material and in that at least the central section (4c) forms the pressing means (5′).

### Claim 3 (depends on 1)

The device (1) according to claim 1, wherein the end sections (4a, 4b) have a triangular cross-section, at least at the level of their front side (40), which is intended to rest against the interproximal gap.

### Claim 4 (depends on 1)

The device according to claim 1, wherein each of the end sections (4a, 4b) comprises at least one gripping means arranged to allow moving the end sections (4a, 4b) away from one another.

### Claim 5 (depends on 4)

The device according to claim 4, wherein the gripping means includes at least one cavity (4e) arranged to receive an end of a tool such as pliers.

### Claim 6 (depends on 1)

The device according to claim 1, wherein at least one of the end sections (4a, 4b) comprises a slot (4f) for the passage of the support (3).

### Claim 7 (depends on 1)

The device according to claim 1, wherein the guiding support (3) is arranged to define a dental splint.

### Claim 8 (depends on 7)

The device according to claim 7, wherein the guiding support (3) is made out of one of a flexible metallic, a synthetic material or a composite material.

### Claim 9 (depends on 1)

The device according to claim 1, wherein the device is a single-use device.
