The document discusses the neutrocentric concept for arranging teeth in complete dentures. The neutrocentric concept proposes using flat teeth without any inclines in any direction to minimize forces that could cause denture instability. The key aspects are using a single flat plane of occlusion parallel to the residual ridges and eliminating cusps and inclines on posterior teeth to direct forces towards the supporting tissues. This concept aims to preserve residual ridge integrity by preventing destructive forces.
