Regardless of the abutment material or technique, an impression of the abutment is then taken and a crown secured to the abutment with dental cement. Another variation on abutment/crown model is when the crown and abutment are one piece and the lag-screw traverses both to secure the one-piece structure to the internal thread on the implant.
A crown is used to cover a tooth and may be commonly referred to as a "cap." Traditionally, the teeth to be crowned are prepared by a dentist, and records are given to a dental technician to construct the prosthesis. The records include models, which are replicas of a patient's teeth, and the impressions used to make these models.
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. They are most often used when the abutment teeth are whole and sound (i.e., no crowns or major fillings). [4]
