Controllably dissolvable silica-xerogels prepared via sol-gel process and their use. A delivery device including controllably dissolvable silica-xerogel into which structure a biologically active agent is incorporated. Pharmaceutical preparations including this device. Medical devices for orthopedic and surgical purposes which contain controllably dissolvable silica-xerogels, which may further include a biologically active agent.

Dissolvable oxides for biological applications

The invention relates to an applicator system () for application of a prefabricated reinforced composite post or anchor in its non-cured form into a dentinal canal (). The invention is characterized in that the applicator system () comprises a prefabricated fiber-reinforced composite post or anchor in its non-cured form comprising a matrix and fibers, and an applicator tube () having a first end and a second end, wherein the inner diameter dof said tube () is at most 5% larger than the outer diameter Dof said post or anchor in its non-cured form, and the outer diameter Dof the second end of said tube () through which the post or anchor is applied into the dentinal canal () is 0,5-2 mm. The invention further relates to the use of said applicator system.

Applicator system for dental posts and anchors and use of said applicator system

The invention relates to a method and silicone product for shaping a fibre product used in dentistry to reinforce a prosthetic appliance or a similar structure under construction to conform to the final location. The fibre product containing fibres and curable material is pressed by means of silicone material against the final location or a model thereof followed by curing the curable material present in the fibre product. The invention is characterized in that the silicone material is a polymerised, elastic and soft silicone material that has been shaped to a piece () corresponding to the size and shape of the fibre product to be shaped, and that when pressed, the silicone material adopts the shape of the final location or the model thereof.

Method and product for shaping a fibre product for dental use

The use of a prepreg containing at least one fiber and a matrix to be cured during application, for the production of a fiber-reinforced composite, for active orthodontic therapy. An active orthodontic appliance is disclosed which includes an arch wire in at least one part, directly contactable with teeth and including a fiber-reinforced composite containing at least one fiber and a matrix, the arch wire including a loop directly contactable with a tooth or teeth to be moved by the appliance. A process for manufacturing an active orthodontic appliance and to an active orthodontic method of treatment are also disclosed.

Orthodontic appliance

An applicator system ( ) which includes a fiber-reinforced composite (FRC) post ( ) or anchor in its non-polymerized form including a resinous matrix and fibers, i.e., a prepreg ( ); and an applicator tube ( ). The inner diameter (d ) of the tube ( ) is essentially the same or slightly larger than the outer diameter (D ) of the FRC post ( ) in its non-polymerized form. The outer diameter (D ) end of the tube through which the FRC post is applied is essentially the same or slightly smaller that the coronal opening of the canal ( ). The applicator system ( ) may be used to prepare permanent or temporary root canal ( ) posts, to make a tooth canal ( ) filling and to make a post and/or anchorage system that forms a continuous FRC structure from the apex of the tooth to the coronal part of the tooth.

Plastic based composite and its use

Prepreg

A device for use particularly in reinforcement of teeth or dental prosthetic devices, where the device is used for wetting and for application of a reinforcing fiber bundle. The device includes a flexible pipe through the first end of which the reinforcing fiber bundle can be inserted and through the second end of which the reinforcing fiber bundle can be removed, where the wall of the pipe is treated so as to be essentially opaque to light intended for the curing of the reinforced fiber bundle, and a nozzle arranged at the second end of the pipe, the cross-section of the nozzle being smaller than the cross-section of the pipe.
