Want to learn more about our crown and bridge process at flora see our article.Lithium disilicate is an outstanding material inside its envelope and an unreliable one outside it. This guide sets out where that envelope sits: when e.max is the right call and when it is not how we fabricate it at Flora, and [...]
This UK crown and bridge lab guide for dentists covers what our crown and bridge lab fabricates, from a single crown to a multi-unit bridge, what to send, the materials we offer, our digital workflow, and turnaround. Crown and Bridge Materials at a Glance MaterialBest forPreparationKey considerationZirconia (monolithic)Posterior strength, bruxers, minimal spaceConservativeStrongest option; less translucent [...]
Most dentists do not change crown and bridge laboratory because the fabrication is poor. They change because of everything around the fabrication the crown that needs adjusting at every fit, the bite that was never quite right, the case that comes back a week later than promised, the shade query that goes unanswered. The technical [...]
The metal crown has a marketing problem, not a clinical one. Patients arrive at the chair having read that metal crowns are obsolete, allergenic, or even toxic: one widely-ranked patient article claims they contain mercury, which is simply wrong (dental amalgam contains mercury; cast crowns and PFMs do not). Meanwhile, the clinical record tells the [...]
Most material comparisons still describe this as a simple trade-off: zirconia is strong but opaque, e.max is beautiful but weaker. That description is a decade out of date. The arrival of high-translucency 4Y and 5Y zirconia has narrowed the aesthetic gap, and "zirconia" now spans materials from ~500 MPa to ~1,400 MPa. The real question [...]
For most practices, zirconia is now the default posterior crown, and that is exactly where the modern mistake hides. "Zirconia" is no longer one material. The shift from first-generation opaque 3Y zirconia to today's 4Y and 5Y high-translucency formulations means a single word now covers materials ranging from nearly unbreakable to genuinely aesthetic, with very [...]
Most bridge failures are design failures, not fabrication failures. A connector sized under the fracture threshold, a Maryland wing asked to do a conventional bridge's job, a cantilever hung off the wrong abutment, a pontic form the patient cannot clean by the time any of these reaches the laboratory bench, the outcome is already decided.
