Tooth movement an alternative to bone transplants

10.10.2011
Although replacing lost teeth often involves artificially building up the jaw, researchers at the Sahlgrenska Academy at the University of Gothenburg, Sweden, are now showcasing a new method whereby teeth are instead moved into the toothless area using a brace, giving patients the chance of having more teeth.

When we lose our teeth, perhaps because of illness or injury, the jaw in the toothless area also decreases in volume. This reduction makes it difficult to carry out dental implants, often leaving just one option for replacing lost teeth: building up the jaw with bone transplant.

Alternative method

Researchers at the University of Gothenburg’s Sahlgrenska Academy are now presenting an alternative method. In an experimental study on dogs, the Gothenburg researchers managed to use a brace to move existing teeth into a toothless area with limited bone volume, without any reduction of the tooth's natural attachment in the jaw.

In a subsequent clinical study, consultant Orthodontist Birgitta Lindskog Stokland and her colleagues also managed to show that the same procedure in humans caused only small changes in the tissue around the tooth.

No lasting problems

"X-rays showed some damage to the root known as root resorption, but this didn’t seem to cause any lasting problems," says Lindskog Stokland. "What’s more, our follow-ups a year later showed that the damage had lessened."

The original site of the moved tooth suffers a reduction in bone mass and dental tissue volume, though not to the same extent as when teeth come out for other reasons. This means that this area is well-suited to implants or other tooth replacements, without there being any need for bone transplants.

More teeth more easily

"In other words, many patients can be given more teeth more easily," says Lindskog Stokland.

The thesis has been successfully defended.

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
