Abstract: Certain embodiments of the invention relate to a method of manufacturing a dental bridge. In certain embodiments of the method, a pre-sintered blank made from a green body of ceramic material is subjected to a machining operation that transforms the blank into an intermediate product with a bridge structure and a support body linked to the bridge structure by one or several retaining sections that extend from the support body to the bridge structure. In certain embodiments, a sintering operation is then performed on the intermediate product while the retaining section(s) still link(s) the support body to the bridge structure.

Abstract: A device, kit, and method are provided for distracting bone. The device can comprise a bar and at least one connection interface. For example, the bar can comprise a first connection interface configured for releasable connection of the bar to at least one fixture inserted in a bone portion to be distracted. A second connection interface can be configured to connect the bar to a level adjustment device for distracting the bone portion.

Abstract: A backrest includes first and second side wings and connectors configured to connect the first and second side wings to the wheelchair frame. The first side wing comprises a plurality of transverse profiles extending towards the second side wing and the second side wing comprises a plurality of second transverse profiles extending towards the first side wing. At least one first transverse profile of the first side wing and at least one associated second transverse profile of the second side wing are at least partially mutually embraced in a slidable manner. The at least one first transverse profile and the at least one second transverse profile are dimensioned and configured so that the mutual slidably embracement of the at least one first transverse profile and the at least one second transverse profile is made on a range of distances enabling the width adjustment of the backrest.

Abstract: A backrest for a wheelchair includes an adjustable cushion support, a backrest frame, and attachment members. The adjustable cushion support supports a backrest cushion, and substantially defines plane P1. The backrest frame holds the cushion support and has two substantially parallel side posts substantially defining a plane P2. The attachment members attach the cushion support to the backrest frame. The cushion support comprises two side bars and a plurality of transversally extending and vertically spaced apart flexible straps. Each strap is length adjustable. The cushion support comprises at least two connecting plates. Each plate being integral with one of the side bars and being provided with at least two parallel adjustment slots. The slots define an angle ?, with said plane P1 of the adjustable support cushion. The attachment members are slidably mounted on the slots, enabling depth, width and angular adjustment of the cushion support on the backrest frame.

Abstract: A floor assembly, such as a bowling floor, is supported above a sub-floor by telescoping pedestal supports that are vertically extendable and vertically retractable. Upper and lower ends of the pedestal supports are fixed to the floor assembly and the sub-floor, respectively, so that when a pedestal support is vertically retracted, a downward force will be applied to the floor assembly, for removing bulges in the floor assembly for example.
