When choosing a cement for indirect restorations, there are several key factors that must be considered to ensure a successful and long-lasting outcome:
First and foremost is the retention of the preparation. The retention of preparation is determined by factors such as height of abutment, convergence angle of preparation and anatomy of teeth.
The type of substrate being used also plays a pivotal role. Different materials, such as ceramics, metals, or composite resins, may require specific types of cements or pretreatments tailored to their individual properties. Understanding the nuances of each material is crucial to selecting the appropriate cement to create a durable and reliable bond.
Furthermore, the type of restoration being used is a key determinant. Crowns, bridges, inlays, and onlays each have distinct requirements. The cement must be compatible with the specific restoration type to ensure longevity and prevent debonding.
Additionally, the ability to isolate the treatment area is of paramount importance in cement selection. For most resin cements, any residual moisture can compromise the adhesive bond, whereas glass ionomer cements are typically more moisture-tolerant. Therefore, the chosen cement should be appropriate for the clinical environment.
The retention of the preparation, compatibility with the substrate, suitability for the restoration type, and the capacity to work in the given clinical conditions are all vital factors in the selection of cement for indirect restorations. By carefully considering these aspects, dental professionals can select the optimal cements and enhance the longevity and effectiveness of their treatments.
