Abstract

Operation splint for bimaxillary operations, characterized in that the operation splint is divided into an upper clear portion (1) and a lower yellow portion (2) and contains the information of four jaw positions, the upper clear portion (1) having the lower yellow portion (2) is firmly connected by ligature wire (3),
the surgical splint is reinforced vestibularly and perforated several times,
the operation splint in the posterior region is dynamically designed in the anterior region and statically, with the surgical splint partial dentures or plastic teeth can be attached with the Operationssplint always consistent two-tone, clear and yellow formed and the center of the operating splint, for better centering, red marked.

Description

The The invention relates to an operation splint for bimaxillary operations according to the preamble of Claim 1.

at the well-known bimaxillary operation procedures two pins are needed each of the surgeon the new position of the upper jaw or the of the lower jaw pretend. The sapwood will be between the rows of teeth placed and over the brackets on the teeth intermaxillary wired.

The Lead cotter pins the surgeon, in two steps to the planned surgical result.

Each of these pins carries in itself two pieces of information.
The first sapwood: upper jaw new situation-lower jaw old situation
The second sapwood: upper jaw new location lower jaw new location

At the Changing the first splint to the second splint requires intermaxillary wiring Upper jaw loosened to the lower jaw, the first split pin removed and the second split pin introduced and wired again intermaxillary become.

In In this surgical section, the upper jaw segments are only through the Miniplates fixed on the bone and the surgical result is unstable.

intraoperative It may be after a segmentation of the upper jaw when changing the Splint to a minimal displacement of the upper jaw segments to each other come in this OP phase, the segments of the upper jaw one Stabilization are robbed by the sapwood.

This leads to a poor fit of the final splint and reposition these segments by the surgeon.

Such an arrangement is for example from the DE 40 18 273 C2 known. After removal of the intermaxillary immobilization by removal of the wire ligatures, a first surgical splint is removed and the osteotomy of the obese is performed. After mobilization of the upper jaw segment, a second operating splint is inserted. If, in addition to the upper teeth, the lower teeth are to be repositioned relative to the skull, a third surgical splint is required.

Of the The invention is inter alia based on the object by means of a novel operation splints a shortening of the duration of surgery, a simplification of the surgical procedure and a stabilization the upper jaw segments during to achieve the course of the surgery. This task is solved by an operating splint having the features of claim 1. The operating splint for bimaxillary operations divided into an upper clear portion and a lower yellow Share trained, taking the information of four jaw positions contains. The upper clear portion is with the lower yellow portion through ligature wire firmly connected. The surgical splint is vestibularly reinforced and punched several times. Furthermore, the surgical splint in the posterior Dynamic and anterior in the anterior area, wherein at the operating splint partial dentures or plastic teeth with can be attached. The operation splint is always consistent bicolor, clear and yellow trained and the middle of the operating splint, is for the better Centering, marked in red. The operation splint will be in the further also called "sandwich pin". Further features of the invention will become apparent from the following Description of an embodiment based on the drawings. It shows

3 another view of the Funktionsssplints invention.

• – Oberkiefer neue Lage (klarer Anteil),
• – Unterkiefer alte Lage (gelber Anteil),
• – Oberkiefer neue Lage (klarer Anteil),
• – Unterkiefer neue Lage (klarer Anteil wenn gelber Anteil entfernt wird).

The new sandwich pin wears, as in 2 and 3 shown in four following position information:

• - upper jaw new situation (clear part),
• - lower jaw old position (yellow part),
• - upper jaw new situation (clear part),
• - Mandible new position (clear part if yellow part is removed).

The new sandwich pin is directly connected to the upper, clear, vestibular reinforced and perforated portion ( 1 ) wired to the brackets of the maxillary teeth.

The Wiring is not done with the sapwood over the sapwood (old method) to the brackets of the mandibular teeth respectively.

at a two or three-part upper jaw can now individually the respective upper jaw segments be pulled into the sandwich cotter, and in the new position and in the new position to each other, at the upper vestibular reinforced, perforated Part of the splint to be fixed in situ.

Then be the segments fixed with miniplates.

One Changing the split pins is not necessary (old method).

Only the lower yellow portion ( 2 ) from the upper clear portion ( 1 ) separated, wire connection ( 3 ), without the wiring ( 4 ) of the splint to the upper jaw segments must be solved.

The Operation result remains stable, because the sap serves as stabilization.

At the Sandwichsplint after 3 the upper clear part ( 1 ) the new maxillary and mandibular position and the yellow portion ( 2 ) the old position of the lower jaw, thus both ( 1 . 2 ) together.

Both sapwood shares ( 1 . 2 ), with ligature wire ( 3 ), firmly connected. A wiring ( 4 ) of the splint is made to the upper jaw segments.

Claims (1)

Operationssplint bimaxillary for operation processes, characterized in that the two divided Operationssplint (in an upper clear portion 1 ) and a lower yellow portion ( 2 ) and contains the information of four jaw positions, the upper clear portion ( 1 ) with the lower yellow portion ( 2 ) through ligature wire ( 3 ), the surgical splint is vestibular reinforced and perforated several times, the operation splint in the posterior region is dynamic and structurally configurable in the anterior region, where at the operating splint partial dentures or plastic teeth can be attached with the Operationssplint always consistent bicolor, clear and yellow formed and the center of the surgical splint is highlighted in red for better centering.
