One major advantage of the resin-retained bridge over a conventional bridge is the failure mode is likely to be debonding of the retainer. In conventional bridges , the failure mode is likely to be complete fracture of the abutment tooth with difficult-to-manage sequelae, possibly requiring root canal treatment .
An alternative to the traditional bridge is the resin-bonded or adhesive bridge (also called a Maryland bridge). A resin-bonded bridge utilises retainer "wings" on the sides of the pontic which attach it to the etched enamel of the abutment teeth. Abutment teeth require minor or no preparation.
Research has reflected a survival rate of 80% over a period of 6 years or longer, [88] and that cantilever resin-bonded bridges are at least as good as conventional fixed-fixed bridges. Restoring teeth with this method can only be done after orthodontic treatment and will need an element of retention to ensure that tooth contacts are not misplaced.
A 3D printing company, MX3D based in the Netherlands is planning to print a 3D bridge over a canal in the center of Amsterdam. The inventors created a robotic structure that can fully rotate to ...
Further examples include nigh guard and tooth-bonded plastic. 2. Intra-coronal splints: The stabilising device is placed into a small chamber within the tooth that are milled by the dentist, and bonded or cemented into place. This means the splint is less visible, making it a more aesthetically acceptable option. Examples: Inlays, and nylon wires.
These materials protect the pulp from noxious agents (heat, cold, bacteria) and stimulate the cell-rich zone of the pulp to lay down a bridge of reparative dentin. Dentin formation usually starts within 30 days of the pulp capping (there can be a delay in onset of dentin formation if the odontoblasts of the pulp are injured during cavity ...
However, fewer reactive resin groups are available to bond to the resin luting cement indicating lower accuracy in fitting compared to the other materials. [33] However, using this indirect laboratory method demands more skill and time, and is more destructive as tooth preparation is needed prior to taking an impression.
Resin-based glass ionomers have two setting reactions: an acid-base setting and a free-radical polymerisation. The free-radical polymerisation is the predominant mode of setting, as it occurs more rapidly than the acid-base mode. Only the material properly activated by light will be optimally cured. The presence of resin protects the cement ...
