The area where the outward forces from the tongue and the inward forces from the lips and cheeks are nullified during the functional movements is referred to as the neutral zone. Therefore, the incorporation of neutral cone technique serves as an alternative approach in the fabrication of lower complete dentures specifically in ridges which are highly atrophic. The technique aims to construct a denture that is shaped by muscle function and is in harmony with the surrounding oral structures. It is rarely used because of the extra clinical step involved and some clinicians may find the detection of neutral zone difficult. This article describes a technique for improving the stability of mandibular complete denture for patients who have a resorbed mandibular residual ridge.This neutral zone impression technique is a useful technique when providing mandibular complete denture. It’s use can overcome some of the denture stability difficulties caused in some patients with a more powerful oral musculature, or in patients who have poor or altered neuromuscular control.

A fibrous which is also called as hyperplastic ridge is a superficial area of mobile soft tissue affecting the maxillary or mandibular alveolar ridges. It develops when alveolar bone gets replaced by hyperplastic soft tissue and is a common finding particularly in the upper anterior region seen in long term denture wearers. Masticatory forces often displace this mobile denture-bearing tissue, which leads to altered denture positioning and loss of peripheral seal. Forces exerted during the act of impression making results in distortion of the mobile tissue. Unless it is managed appropriately by special impression techniques, such ‘flabby ridges’ adversely affect the support, retention and stability of complete dentures. This paper presents prosthodontic management of a patient with flabby ridges with special impression technique.
