DIMENSIONAL AND FORMATION ANALYSIS OF A RESTORATIVE CERAMIC AND HOW IT WORKS

In-Ceram ceramic appears to use conventional powder/liquid processing techniques to form the coping substructure; however, the process resul ts in a near net-shape restoration with minimal sintering shrinkage, S canning electron microscopy, Brunauer-Emmett-Teller analysis, particle size classification, and linear dimensional changes during sintering were used to analyze In-Ceram ceramic, In-Ceram ceramic had a minimal linear shrinkage of 0.21% after the sintering of the alumina powder, T his shrinkage can be readily compensated for by the expansion of conve ntional gypsum products and should result in acceptable clinical fits for In-Ceram ceramic restorations. Theories and explanations were desc ribed to account for the near net-shape and high strength of ln-Ceram. Continuous interpenetrating phase composite technologies were used to create a substantial increase in strength, Future applications of thi s technology are encouraging.
