ABSTRACT
Introducción: Las rehabilitaciones completas se han visto limitadas por los accidentes anatómicos de los maxilares, por lo que diversas técnicas han surgido durante los años para la colocación de los implantes necesarios. Entre ellas, el concepto de All-On-4 permite la rehabilitación de una arcada completa con cuatro implantes, que serán colocados cerca de estructuras anatómicas en pacientes con reabsorciones óseas severas, evitando así cirugías adicionales. Materiales y métodos: El tipo de estudio fue un estudio observacional descriptivo, retrospectivo y transversal en el que se seleccionaron un total de 12 pacientes: 6 pacientes rehabilitados mediante el protocolo de All-on-four (Grupo 1) y 6 pacientes rehabilitados con una prótesis híbrida sobre seis implantes (Grupo 2). Se analizó: Tipo de tratamiento; Nivel de inflamación gingival; Pérdida ósea marginal; Nivel de satisfacción; Complicaciones biológicas y mecánicas; Sexo; Edad. Resultados: En las variables más importantes, se observó que el índice de sangrado fue ligeramente mayor para el Grupo 1. La pérdida ósea marginal fue mayor para el grupo 2. Los pacientes se sentían a gusto con ambos tratamientos, pero el valor es más alto para el Grupo 1. Conclusiones: El índice de satisfacción global analizado resulta alto en ambos grupos y permite valorar de forma muy positiva las dos planificaciones de tratamiento. No hay relación entre las variables sexo, edad o tipo de tratamiento y el nivel de satisfacción. No se puede determinar una relación entre el tipo de tratamiento y el índice de sangrado o pérdida ósea marginal. (AU)
Introduction: Full-arch rehabilitations are limited by the anatomical structures of the maxillas, so different techniques have been proposed for the placement of implants. The All-On-4 concept allows for full-arch rehabilitation with four implants, which will be placed near anatomical structures in patients with severe bone resorption, avoiding additional surgeries. Material and methods: The study design is an observational, descriptive, retrospective and transversal study, which gathered 12 patients: 6 patients treated with the All-On-4 protocol (Group 1) and 6 patients with a hybrid prostheses supported by 6 implants (Group 2). The variables analyzed were: Treatment type; Bleeding on probing; Marginal bone loss; Grade of satisfaction; Biological complications and mechanical complications; Gender; Age. Results: The most important variables showed that Bleeding on probing was slightly higher for Group 1. Marginal bone loss was higher for Group 2. Patients were all satisfied with both treatment options, but the results were higher for Group 1. Conclusions: The global satisfaction index is high in both groups, which rates both treatment options as very positive. There is no relation between gender, age or treatment option and the level of satisfaction. A correlation cannot be made between the treatment option and marginal bone loss or bleeding on probing.

To date, topical therapies guarantee a better delivery of high concentrations of pharmacologic agents to the soft periodontal tissue, gingiva, and periodontal ligament as well as to the hard tissue such as alveolar bone and cementum. Topical hyaluronic acid (HA) has recently been recognized as an adjuvant treatment for chronic inflammatory disease in addition to its use to improve healing after dental procedures. The aim of our work was to systematically review the published literature about potential effects of HA as an adjuvant treatment for chronic inflammatory disease, in addition to its use to improve healing after common dental procedures. Relevant published studies were found in PubMed, Google Scholar, and Ovid using a combined keyword search or medical subject headings. At the end of our study selection process, 25 relevant publications were included, three of them regarding gingivitis, 13 of them relating to chronic periodontitis, seven of them relating to dental surgery, including implant and sinus lift procedures, and the remaining three articles describing oral ulcers. Not only does topical administration of HA play a pivotal key role in the postoperative care of patients undergoing dental procedures, but positive results were also generally observed in all patients with chronic inflammatory gingival and periodontal disease and in patients with oral ulcers.
