Jaw Positioning Device - Precise midface-related maxilla repositioning during orthognathic surgery

11.04.2013
Occlusion irregularities can surgically be treated by corrective osteotomies of mandible and / or maxilla. However, exact midface-related repositioning of the maxilla after LeFort I Osteotomy remains challenging, as the mobilised parts of the jaw are free to move three-dimensionally. Previous approaches are all afflicted with considerable inaccuracy and some of them are associated with additional radiation exposure caused by three-dimensional imaging.

This invention allows exact midface-related maxilla repositioning during mono- or bimaxillary surgery. The jaw positioning device comprises three splints (primary-, secondary- and reference splint) and three connection bars. The maxillary shift is planned preoperatively by model-surgery and encoded by the difference between primary- and secondary splint. There is no need for navigational systems or complex bone models based on three-dimensional imaging. During surgery, the primary splint, which fits exactly to the occlusional surfaces of the maxillary teeth, is placed on the dental arch. The primary splint’s outer face features a definded surface profile, on which the reference splint is placed. In the next step, connection bars to three intraorally accessible points of the patient’s bony midface are fixed on the reference splint. In this way, the reference splint can be replaced exactly in a well-defined midface-related position, also without the primary splint. After LeFort I osteotomy, the maxilla can be precisely positioned at the target position by use of the secondary splint, that also fits exactly to the corresponding surface of the reference splint.

Im Focus: Electron highway inside crystal

Physicists of the University of Würzburg have made an astonishing discovery in a specific type of topological insulators. The effect is due to the structure of the materials used. The researchers have now published their work in the journal Science.

Topological insulators are currently the hot topic in physics according to the newspaper Neue Zürcher Zeitung. Only a few weeks ago, their importance was...

Im Focus: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
