ABSTRACT
RESUMEN: En los hospitales públicos chilenos, los pacientes desdentados mandibulares pueden ser tratados con una Sobredentadura-Mucosoportada, Implanto-Retenida (SMIR). Para tal fin, se adaptaron los lineamientos del plan piloto "Programa de Prestaciones Valoradas. Odontología 2012 Ministerio de Salud", en ausencia de una Guía Ministerial. El objetivo de esta serie de casos fue evaluar si la implementación y adaptación del plan piloto del tratamiento con SMIR mejoró la calidad de vida de los pacientes. Se evaluaron sobrevida, éxito implantario, e impacto en la calidad de vida. Los resultados indican una sobrevida y éxito implantario del 100% y una mejora de la calidad de vida. Conclusión: el tratamiento con SMIR mejora la calidad de vida de los pacientes, en el servicio público.
ABSTRACT: In Chilean public hospitals, patients with Complete Edentulous Mandible are treated with Implant-Retained and Mucosa-supported Overdenture (IRMO). For this purpose, the guidelines of the pilot plan "Valued Benefits Program in Dentistry 2012, Ministry of Health" have been adapted. The aim of this study was to evaluate whether these adapted protocols have been successful. We measured implant survival and success, and impact on quality of life with OHIP-14 criteria. Results indicate 100% implant survival and success and improved quality of life. Conclusion: IRMO improves patients' quality of life in public services.
ABSTRACT
Prosthetic rehabilitation of an edentulous patient who has a maxillary defect is difficult to achieve for many clinicians. The maxillary defect causes leakage of air during pronunciation and compromises denture stability, support and retention by reducing denture-bearing area and breaking peripheral seal. In these patients, the sizes and shapes of defects are very important factors which attribute to prognosis of maxillary obturators. This case report shows the prosthetic rehabilitation of the patient who had maxillectomy on the right maxillary sinus because of squamous cell carcinoma. The patient had a stepwise treatment protocol which started with pre-operative dental examination and followed by surgical, interim and definitive obturation phase. In this case, an acceptable level of retention could be obtained due to well-defined static defects and the preserved premaxillae and the patient was satisfied with the result of the treatment in the aspect of function and esthetics.

Most patients with acquired maxillary surgical defects have difficulties such as functional impairments of mastication, speech, and deglutition as well as various degrees of facial deformity. The purpose of a prosthetic approach is to restore function and appearance with an obturator as normal as possible. This goal can be achieved when there is thoughful preoperative communication between a prosthodontist and a surgeon regarding a rehabilitation. In this case report, prosthetic rehabilitation was planned before the surgery for the patient diagnosed with squamous cell carcinoma in the right maxillary sinus with careful oral examination. Four months after maxillectomy, a definitive obturator was fabricated following the surgical and interim obturation phase. The objective of this case report is to describe the satisfactory results of the patient with improved rehabilitation of mastication, speech, deglutition, and appearance.

Implant fixed prosthesis for the complete edentulous maxilla provides significant benefits in the aspects of functions and esthetics compared with the conventional denture. Implant supported fixed prosthesis are totally supported by implant, and thus stabilizes the prosthesis to the maximum degree as possible. Also, the improved retention and stability of fixed prosthesis enhance patients' psychological and psychosocial health. This clinical presentation describes a maxillary full arch implant-supported fixed prosthesis in complete maxillary edentulous patient who showed vertical and horizontal alveolar bone resorption in the anterior ridge. To rehabilitate the esthetics and proper lip support, the zirconia framework was fabricated and the pink porcelain was veneered to reproduce the natural gingival tissue. After 9 months of follow up, the restorations were maintained without complications and the patient was satisfied with the restoration both functionally and esthetically.

Objetivo: Comparar, no plano horizontal, as posições mandibulares determinadas por dois métodos de registro para determinação da posição de relação central (RC): inclinação da cabeça para trás (IC) os métodos guiado não forçado (GNF), em pacientes edêntulos. A hipótese nula é de que não haverá diferença entre os dois métodos. Material e Método: 20 pacientes desdentados totais foram selecionados para este estudo (n=20). Todos pacientes foram manipulados para posição de RC utilizando os métodos IC e GNF. A mensuração da posição de RC determinada por cada método foi registrada em um dispositivo extra-oral, cujas componentes foram fixados nos planos de orientação maxilar e mandibular. Para cada paciente, as duas posições de RC foram registradas no mesmo dispositivo extra-oral. Para mensurar as variações ânteroposteriores e laterais entre os pontos registrados por cada técnica, foi utilizado um projetor de perfil (Modelo 6C, Nikon/ USA). Os dados (mm) foram analisados estatisticamente utilizando o teste T (p<0.05) e o teste de correlação de Pearson. Resultados: A diferença entre a posição de RC obtida pelos métodos na posição ântero-posterior diferiu estatisticamente de zero (p=0.001) e que não houve diferença significante (p=0,479) quando comparada as posições de RC em relação à linha média: UHM (0,56±0,35mm) e IHB (0,65±0,52mm). Não foi observada correlação linear de Pearson entre as medidas lineares antero-posteriores e laterais dos métodos estudados (r=0,26; p=0,268>0,05). Conclusão: Pode-se concluir que método GNF gerou uma retrusão mandibular maior que o método IC.
Objective: To compare, in the horizontal plane, the mandibular positions determined by two methods for registering the centric relation (CR): inclination of the head backward (IHB) and unstrained hinging movement (UHM), in edentulous patients. The null hypothesis was that there is not difference between the two methods. Material and Methods: Twenty edentulous subjects were selected for this study (n=20). All patients were manipulated to CR position using the methods IHB and UHM. The CR measure of each method was registered in one extraoral device, which was fixed at the maxillary and mandibular record bases. For each patient, the two CR positions were registered in the same extraoral device. To measure the anteroposterior and lateral linear variations between the points registered for each technique, it was used a profile projector (Model 6C, Nikon/USA). The data (μm) were statistically analyzed using the Tukey test (p<0.05) and Pearson correlation test. Results: The difference between CR position obtained by the methods in anteroposterior position differed statically from zero (p=0.001) and that there was no significant difference (p=0.479) when compared the CR positions with the medium line: UHM (0.56±0.35ìm) and IHB (0.65±0.52ìm). It wasnt observed Pearson linear correlation between the anteroposterior and lateral linear measures of the methods (r = 0.26; p = 0.268>0.05). Conclusion: It can be conclude that the method UHM presented a higher mandibular retrusion than the method IHB.
