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.

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

Background: Emergency treatments determined by emergency physicians may affect mortality and patient satisfaction. This paper attempts to examine the impact of patient characteristics, health status, the accredited level of hospitals, and triaged levels on the following emergency treatments: immediate life-saving interventions (LSIs), computed tomography (CT) scans, and specialist consultations (SCs). Methods: A multivariate logistic regression model was employed to analyze the impact of patient characteristics, including sex, age, income and the urbanization degree of the patient’s residence; patient health status, including records of hospitalization and the number of instances of ambulatory care in the previous year; the Charlson Comorbidity Index (CCI) score; the accredited level of hospitals; and the triaged level of emergency treatments. Results: All the patient characteristics were found to impact receiving LSI, CT and SC, except for income. Furthermore, a better health status was associated with a decreased probability of receiving LSI, CT and SC, but the number of instances of ambulatory care was not found to have a significant impact on receiving CT or SC. This study also found no evidence to support impact of CCI on SC. Hospitals with higher accredited levels were associated with a greater chance of patients receiving emergency treatments of LSI, CT and SC. A higher assigned severity (lower triaged level) led to an increased probability of receiving CT and SC. In terms of LSI, patients assigned to level 4 were found to have a lower chance of treatment than those assigned to level 5. Conclusions: This study found that several patient characteristics, patient health status, the accredited level of medical institutions and the triaged level, were associated with a higher likelihood of receiving emergency treatments. This study suggests that the inequality of medical resources among medical institutions with different accredited levels may yield a crowding-out effect.
