Neutral Zone Technique for Rehabilitation of Resorbed Mandibular Ridge

ABSTRACT The neutral zone technique is an alternative approach for the construction of the complete dentures. It is most effective for cases where there is a highly atrophic ridge. The technique aims to construct a denture, i.e., shaped by muscle function and is in harmony with the surrounding oral structures. This clinical report describes the fabrication of complete dentures for a patient with poorly formed mandibular ridges.

Mandibular Complete Denture

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.

Oral Malignancies

ABSTRACT Oral malignancies originating from or secondarily involving mandible are usually treated by surgical excision and may result in mandibular defect with or without loss of continuity. Surgical resection may lead to loss of buccal and lingual sulci, loss of symmetry of mandibular function, altered mandibular movements and deviation of the residual fragment toward the resected side. Radiation therapy is often given after resection of malignant tumors, which may produce undesirable side effects, like mucositis and mucosal atrophy, trismus, increased susceptibility to irritation and ulceration and reduction in salivary flow. This overall change in anatomy and physiology of oral cavity after segmental mandibular resection presents a restorative challange. This clinical report presents fabrication of complete dentures for a patient who had undergone segmental mandibulectomy and had restricted mouth opening.

And Function

Patients with resorbed mandibular ridge poses a challenge for prosthodontic rehabilitation. The ongoing diminution of denture foundation defies the basic mechanism of denture stability and support. The technique of neutral zone to construct a denture that is shaped by muscle function and is in harmony with the surrounding oral structures can remarkably improve prognosis of such patients. The neutral zone is the area in the oral cavity where during function; the forces of the cheeks and lips pressing inward neutralize the forces of the tongue pressing outward. Thus physiologically optimal teeth arrangement and harmonious denture contours and can be achieved to maximize prosthesis stability, comfort, and function for patients. This clinical report describes rehabilitation of a patient with severely resorbed mandibular ridge using neutral zone impression technique.
