Using the neutral zone to obtain maxillomandibular relationship records for complete denture patients

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.

And Function

Providing complete denture therapy to patients with atrophic residual alveolar ridges is challenging because such patients suffer ongoing diminution of the denture foundation. Modern approaches often involve dental implant therapy as a means of improving the denture function and supplementing the mechanics of prosthesis support, retention and stability. Regardless of implant availability, physiologically optimal denture contours and appropriate teeth arrangement should be achieved to maximize prosthesis stability, comfort and function for patients. The neutral zone concept implies acquired muscle control, especially by tongue, lips and cheeks toward the denture stability. In this case, concept of Neutral zone (NZ) and Lingualized occlusal scheme have been incorporated in an effort to provide successful complete denture therapy.

And Function

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.

Implant Dentistry

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.

Resorption of mandibular ridges is a multifactorial and biomechanical disease that is chronic, progressive,irreversible, and cumulative leading to loss of sulcular depth, vertical dimension loss, and decreased lowerfacial height. Some common neurological, hormonal, and metabolic disorders affect the adaptability ofdentures, and this can be diagnosed by a trained prosthodontist with proper history-taking and clinicalexamination. The denture becomes passive due to complex neuromuscular control and causes difficultiesin impression-making, mastication, and swallowing, which in turn leads to loss of retention and stability incomplete dentures. The loose and unstable lower complete denture is one of the most common problemsfaced by denture patients. One of the methods used to solve this problem is the neutral zone technique.Neutral zone technique is long being used for the management of severely resorbed mandibular ridges. Thepiezography technique, a special functional approach is described in order to overcome the difficulties of themandibular denture. Piezography, prosthetic space recorded by pronunciation, can be used as a reference forarrangement of artificial teeth and polishing surface of a denture.

AbstractOne of the most commonly faced problems among long term denture wearers is the reduction in the denture foundation. Prosthetic rehabilitation of a patient with severely resorbed ridge is the most challenging therapy a prosthodontist can undertake. In order to have a favourable prognosis for the denture therapy, impression technique selected should be based on the present state of the basal tissue support. This article presents the application of neutral zone concept being incorporated in impression making to achieve successful complete denture therapy.
