The taper of each preparation on the abutment teeth must be the same. This is known as parallelism among the abutments and allows the bridge to fit onto the abutment teeth. Adhesive bridges require minimal preparation. Master impressions: An accurate impression should be made of the prepared teeth, along with an impression of the opposing arch ...
A Rochette bridge is a type of dental prosthesis popular in the 1970s, [citation needed] and described by Alain Rochette in 1973 [1] as a form of resin retained bridge that relied on countersunk holes perforating the metal abutment wing. These would be filled with composite cement on seating the restoration, providing macromechanical retention ...
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. With a resin-retained bridge the ...
Crown-to-root-ratio is the ratio of the length of the part of a tooth that appears above the alveolar bone versus what lies below it. [1] It is an important consideration in the diagnosis, treatment planning and restoration of teeth , one that hopefully guides the plan of treatment to the proper end result.
In restorative dentistry, precision attachments are the functional mechanical parts of the removable partial denture made of plastic, metal or a combination of both. [1] They consist of two parts referred as the 'male' part that is fixed to a crown inside the patient's mouth and a 'female' part which holds the partial denture.
Named for its jagged, toothy look, the project is expected to be among the more complex in the suite of Gateway projects.
The overall length of the deciduous maxillary central incisor is 16 mm on average, with the crown being 6 mm and the root being 10 mm. [17] In comparison to the permanent maxillary central incisor, the ratio of the root length to the crown length is greater in the deciduous tooth. The diameter of the crown mesiodistally is greater than the ...
Vertical dimension of occlusion, or VDO, also known as occlusal vertical dimension (OVD), is a term used in dentistry to indicate the superior-inferior relationship of the maxilla and the mandible when the teeth are occluded in maximum intercuspation. [1]
