“…There were ample studies that have shown an increase in stability and retention with the use of neutral zone technique only, on the other hand other studies exhibited more retention and stability with using polished surface techniques. [10][11][12] Infact, there is a significant correlation between the horizontal forces by lips, cheeks and tongue and the balanced placed of artificial teeth on dentures that can be achieved by neutral zone technique. 13,14 It is very crucial to understand the patient's oral conditions and to link these findings to the treatment plan.…”

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.

A patient with oral submucous fibrosis and resorbed ridges poses a challenge for prosthodontic rehabilitation because of the limited mouth opening and fibrotic mucosa. The fabrication of prosthesis is very difficult due to abnormal jaw relations, influencing the long-term prognosis of the patient. To present a case of oral submucous fibrosis with severely resorbed edentulous ridges which was successfully managed by adopting a modified technique in fabricating a complete denture prosthesis. A 55-year-old female patient with completely edentulous maxillary and mandibular arches diagnosed with oral submucous fibrosis was rehabilitated with complete dentures by recording neutral zone for resorbed mandibular ridge and by arranging the posterior teeth in cross arch relation for compensation of the abnormal jaw relations. The cross-arch arrangement of posterior teeth provides a more stable and retentive complete denture prosthesis for patients with severely resorbed ridges and a wider mandibular arch.

“…Existen condiciones del paciente que favorecen la inestabilidad protésica, podemos mencionar (5,6,7) : Enfermedad de Parkinson, accidente cerebrovascular, esclerodermia, prominencia del canal mentoniano, pacientes sometidos a resecciones quirúrgicas de la mandíbula, glosectomía parcial, daño del nervio motor de la lengua, pacientes con pobre control neuromuscular, terapia miofuncional, alargamiento quirúrgico de la banda del buccinador, vestibuloplastía, cirugía ortognática, espasmos hemifacial, entre otros. Este útlimo es un transtorno motor caracterizado por la contracción incontrolada, intermitente y espasmódica o tónica de los musculos de una hemicara (7) .…”

RESUMENToda función del sistema estomatognático involucra la acción sinérgica de la musculatura paraprotética, representada por estructuras complejas tales como lengua, labios, mejillas y piso de boca. Al rehabilitar a través de prótesis completas no siempre se considera la influencia de la dinámica muscular, y menos aún cuando alguna de estas estructuras presenten alguna patología, por ejemplo, el compromiso del nervio facial que genera espasmos musculares involuntarios. En tal situación, la ubicación de los dientes y la forma de las superficies pulidas pueden llegar a ser decisivos entre éxito o fracaso de la rehabilitación. Se sabe que los implantes oseointegrados proveen retención, soporte y estabilidad, sin embargo existen situaciones especiales en que no es posible acceder a este tipo de tratamiento, tanto por razones médico quirúrgicas o costos asociados. En este estudio se ha utilizado un registro Piezográfico de la Zona Neutra en un paciente con compromiso del nervio facial que genera espasmos musculares involuntarios del lado afectado, obteniéndose una rehabilitación protésica basada en la apropiada relación entre superficie protésica externa y tejidos circundantes, mejorando requisitos funcionales tales como retención y estabilidad. Se ha utilizado el sistema de tomografía computarizada Cone Beam, con el objetivo de evidenciar el registro piezográfico. Los resultados obtenidos con estas prótesis piezográficas demuestran ser superior en factores como comodidad y fonoarticulación pero inferior en eficiencia masticatoria comparada con la técnica convencional. ABSTRACTEvery function of the stomatognathic system involves the synergistic action of the musculature around the prosthesis, consisting of complex and individual structures such as tongue, lips, cheeks and mouth floor. When planning and making complete prostheses, the muscular dynamic is not always considered. This can generate instability of the device during function, the location of the artificial teeth is made arbitrarily on the top and middle parts of the flange, and the configuration of the polished areas is made according to mechanistic concepts. This factor takes more relevance in patients with severe atrophy of their residual flanges, where the prosthetic stability can be a decisive factor between the success or failure of the rehabilitation. It is known that the osseointegrated implants provide retention, support and stability. However, there are special situations in which it is not possible to access to this type of treatment, both for medical surgical reasons or associated costs. In this study, a Piezographyc record of the Neutral Zone was used in a patient with facial nerve involvement generating involuntary muscle spasms of the affected side. A prosthetic rehabilitation based on the appropriate relation between external prosthetic surface and surrounding tissues was obtained, improving functional requirements such as retention and stability. The computerized tomographic Cone Beam system was used, with the objective to show the piezo...
