ABSTRACT
Patients with collapsed occlusal support and unilateral chewing show parafunctional mandibular movements, which can be complicated in older patients. Gothic arch tracing and split cast technique are used to confirm the deviation between centric relation and anterior habitual bite in patient who has oral dyskinesia and collapsed occlusion. Temporary denture as occlusal stabilization appliance was provided for stable occlusion and reproducible mandibular movement. Definitive denture was fabricated by lingualized occlusion concept.

The patient who has severely absorbed residual ridges, treatments are challenging to satisfy many factors: support, retention, stability, etc. The neutral zone or monoplane occlusion with non-anatomical tooth would be helpful to get additional retention and stability. The monoplane occlusion has been used long time because it can eliminate horizontal forces and many other advantages. The lingualized occlusion was introduced to improve chewing efficiency and esthetics. But from a stability aspect, it seems controversy between monoplane occlusion and lingualized occlusion. This case report shows the results of the treat two flat residual ridge patients using functional impression; piezography, and made 2 other dentures with monoplane and lingualized occlusion that patient can select denture.

Resumen: La displasia ectodérmica es un desorden hereditario caracterizado por un desarrollo anormal de ciertos tejidos y estructuras de origen ectodérmico. La forma más comúnmente observada de displasia ectodérmica es del tipo hipohidrótica. El diagnóstico se basa en la ausencia o disminución de glándulas sudoríparas. Comúnmente es una condición complicada en cuanto al tratamiento odontológico de las deficiencias orales características de este síndrome. Es importante que estas personas reciban atención dental a temprana edad por razones fisiológicas y psicosociales. Este reporte clínico describe las características y el tratamiento prostodóntico de dos hermanos con displasia ectodérmica hipohidrótica.
Abstract: Ectodermal dysplasia is a hereditary disorder characterized by the abnormal development of certain ectodermal-origin tissues and structures. Hypohidrotic type is the most commonly observed form of ectodermal dysplasia. Diagnosis is based on the absence or decrease of sweat glands. Dental treatment of oral deficiencies characteristic of this syndrome is commonly quite complex. Physiological and psychosocial reasons dictate the importance for these patients to receive dental treatment at early ages. The present clinical report describes characteristics and prosthodontics treatment of two siblings afflicted with hypohidrotic ectodermal dysplasia.
ABSTRACT
Many factors should be considered for successful denture treatment at edentulous patients: support, retention, stability, occlusion, esthetics, etc. The patient who has severely absorbed residual ridges, however, treatments are challenging to satisfy those factors. The dentures that use anatomic artificial teeth show good mastication efficiency and esthetics but, can easily lose stability at absorbed ridges. On the contrary, the dentures that use non-anatomic artificial teeth perform better stability but, lower masticatory efficiency and esthetics at absorbed ridges. The lingualized occlusion, using both anatomic and non-anatomic teeth, introduced for compromise those of the pros and cons. At lingualized occlusion, buccal cusps of the teeth do not contact on centric relation. Therefore, direction of the occlusal force towards lingually, then stability of dentures increases. This case report shows the results of the treatment flat residual ridges using complete dentures with ligualized occlusion to increase dentures stability and satisfactory of the patient.

Bell's palsy is an acute-onset unilateral peripheral facial neuropathy. For patients with sequelae of facial paresis, the successful rehabilitation of fully edentulous arches is challenging. This case report described the treatment procedures and clinical considerations to fabricate complete dentures of a patient who showed unilateral displacement of mandible, unilateral chewing pattern and parafunctional jaw movement due to sequelae of Bell's palsy. Gothic arch tracing was used to record reproducible centric relation and lingualized occlusion was performed to provide freedom to move between centric relation and the patient's habitual functional area in fabricating satisfactory dentures in terms of function and esthetics.

En el presente artículo se describen los procedimientos clínicos y de laboratorio que se emplearon para rehabilitar a un paciente parcialmente edéntulo maxilar y mandibular. El tratamiento fue dividido en dos fases. La primera correspondió a la inserción de una prótesis total maxilar inmediata y a una sobredentadura mandibular inmediata con esquema oclusal balanceado. Una vez estabilizados los tejidos del paciente, se realizó la segunda fase del tratamiento, en la cual se cambiaron las prótesis inmediatas por una dentadura maxilar convencional y una sobredentadura dentomucosoportada retenida por aditamentos axiales radiculares. En esta segunda fase del tratamiento se reprodujo la guía anterior de las prótesis inmediatas y se empleó un esquema oclusal lingualizado. Los procedimientos descritos permiten disminuir tiempos clínicos y de laboratorio sin mermar la calidad de la rehabilitación final.
The present article purports a description of laboratory and clinical procedures used to rehabilitate a partially maxillary and mandibular edentulous patient. Treatment was divided into two phases. The first phase encompassed the insertion of an immediate maxillary total prosthesis as well as an immediate mandibular overdenture with balanced occlusal scheme. Once the patient's tissues were stabilized, the second phase of the treatment was undertaken: immediate prostheses were exchanged for a conventional maxillary denture as well as an tooth-supported overdenture retained by root-axial stud-type devices. In this second phase, the immediate prostheses' anterior guide was reproduced and a lingualized occlusal scheme was used. Described procedures allowed the decrease of clinical and laboratory time without endangering the quality of the final rehabilitation.
