A bone distractor to create separation between bone segments by means of a pair of mounts respectively secured to the bone segments and interconnected by means of a drive spring which is secured to one of the mounts and threadedly interconnected to the other mount such that rotation of the drive spring creates sufficient separation of the bone segments to allow for osteogenesis to occur.

Bone distractor

A composition and method for in vitro fertilization is provided which uses culture media comprising elevated concentrations of lipoic acid. More specifically, the invention provides culture media for developmental cells having a lipoic acid concentration of 5 &#x3bc;M to 40 &#x3bc;M. Culture media that include lipoic acid at concentrations within the identified range are able to provide blastocysts with increased survival, increased cell numbers, increased inner cell masses and/or increased percentage of the total mass made up by the inner cell compared to blastocysts cultured in a control medium.

Orthodontic anchorage screw

An orthodontic distractor comprising a pair of telescopically interconnected channels, a drive screw operable to withdraw the inner channel from the outer channel and the outer channel being formed in the shape of a logarithmic curve.

Orthodontic distractor

A base plate mountable in a dental articulator, having a groove forming a closed curve therein. The groove defines a base plate of a smaller size, such that the larger base plate, containing the groove, may be fractured along the groove and a smaller base plate may be used in lieu of the larger one.
