ABSTRACT Objectives A combination of the neutral zone and the polished surface impression techniques is a useful method to reserve the functional and physiological forms of the underlying mandibular residual ridge by enhancing both retention and stability in Malaysian geriatric patients (2-year clinical study). Materials and methods A total of 25 Malaysian geriatric patients have participated in the current study. Two sets of dentures were served to the patients. The first set was constructed according the conventional method of complete denture construction whereas the second set was constructed by using neutral zone and polished surface impression techniques. Results The patients were followed up for 2 years and the obtained results showed that all patients have stopped using the conventional dentures and continued with the test dentures. The comparative analysis exhibited significant difference (p < 0.05) in favor of test dentures. Conclusion Combination of the neutral zone and the polished surface techniques can impart a physiological reservation to the underlying residual ridge without changes. Statement of problem It is common for completely edentulous geriatric patients to have resorbed mandibular residual ridge because of the process of aging. Some surgical interactions are contraindicated for this age group of patients, so, neutral zone technique and/or polished surface impression verified effective in improving stability for lower complete dentures. In spite of the fact that the above mentioned methods often used to enhance stability of complete denture, most of the studies were relying on only one of those methods to improve stability rather than retention. Researcher hypothesis stated that a combination of the neutral zone and the polished surface impression techniques should be performed together to enhance both stability and retention and henceforth reservation of the residual ridge under mandibular complete dentures issued to the patients with a constant follow-up for two consecutive years.

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.

One of the most challenging cases dentists face is the rehabilitation of atrophic mandibular residual alveolar ridges. Such ridges present with a multitude of problems such as decrease in the denture foundation, retention and stability. Instability of denture bases can also give rise to an error in the maxillo-mandibular registrations. The neutral zone concept aims at the construction of complete dentures in the potential denture space, which ensures optimal denture contours and physiological arrangement of denture teeth as determined by the patient’s oral musculature, to enhance the stability and function of the prosthesis. This article presents a classical technique of recording the patient’s neutral zone with an improvised clinical step to record the patient’s maxillo-mandibular relation functionally. This technique can be practised routinely in cases of atrophied mandibular residual ridges to provide the patients with optimal complete denture therapy. Key Words: Neutral zone, resorbed mandibular ridges, maxillo-mandibular records, denture stability

Providing denture service in a completely edentulous situation especially to a patient with poor mandibular foundation is a challenge to the skills of the operator. Recent treatment methodologies like implant supported prosthesis have considerably mitigated the problems faced in such patients. But, implant dentistry may not be feasible in all situations due to certain anatomic limitations and compromised patient health status. Conventional complete dentures with advanced techniques are the only answer in such situations. In the process of fabricating complete denture for a patient with poor mandibular foundation, the placement of the teeth, and contouring of flanges has been debated by various doyens of the science. The piezography technique using the Neutral Zone concept has emerged a strong forerunner in providing good stability and retention in patients having poor mandibular foundation.
