In order for the prosthesis to be functionally, esthetically and phonetically acceptable, it is essential that the prosthesis has adequate stability and retention and does not get displaced with the movement of muscles around it. The soft tissues surrounding the denture form the borders of the prosthesis, therefore the way the denture relates with the muscles is critical.  The neutral zone is region where the forces generated by the muscles surrounding the denture are neutralized. When a denture lies in the neutral zone, it doesnot interfere with the movement of muscles during the physiologic movements. The arrangement of teeth and the contour of the denture is established by the neutral zone. In this case report, the neutral zone of the patient was recorded using the swallowing technique and the arrangement of the teeth was done accordingly.

Keywords: oromuscular forces, deadspace, ridge relations, buccal corridor.
