In the specialized field of Prosthodontics, the Core Build Up is a pivotal procedure that bridges the gap between endodontic therapy and final crown placement. Replacing lost tooth structure with a high-performance Core Build Up material ensures that the final prosthetic has sufficient structural support and mechanical retention. In the local dental market, clinicians prioritize materials that offer high compressive strength and excellent "cut-ability" to mimic the feel of natural dentin during crown preparation. At MedSTA, we provide advanced Core Build Up solutions designed to create a solid, monoblock foundation for every tooth. Utilizing a reliable Core Build Up material is essential for preventing root fractures and ensuring the long-term clinical success of complex restorative cases.
How to Choose the Right Core Build Up Material for Your Practice
Compressive Strength (MPa): Choose a Core Build Up material with a high compressive strength, ideally exceeding 250–300 MPa. This is a technical requirement to ensure the core can withstand the vertical and lateral forces of mastication without fracturing or deforming under the prosthetic.
Dual-Cure Technology: Prioritize dual-cure Core Build Up resins. While light-curing provides immediate surface stability, the chemical-cure mechanism ensures that the material is fully polymerized in the deepest parts of the preparation or inside the root canal during post-cementation.
Radiopacity Levels (% Al): Ensure the Core Build Up material has high radiopacity (typically >200% Al). This allows the practitioner to clearly distinguish between the build-up material, the natural tooth structure, and any potential recurrent caries on future digital X-rays.
Cut-ability and Hardness: Opt for a Core Build Up resin that "cuts like dentin." A material that shares similar hardness with natural tooth structure prevents the bur from "ditching" into the core during crown preparation, allowing for smoother, more accurate margins.
Thixotropic Flow and Stacking: Select a Core Build Up material with thixotropic properties. It should flow easily into the narrow line angles of the cavity but stay "stacked" once placed, allowing the clinician to build up the entire tooth height without the need for a matrix or copper band.
