There is a trend to prefer articles related to biological aspects of psychiatry, centered in evidence-based medicine methodology. An effort should be made to broaden the scope of selection of papers, incorporating, for instance, humanistic views, psychotherapy, and other methodologies.
Muchos trastornos sistémicos como la artritis o la osteoporosis son patologías responsables de las alteraciones crónicas de la articulación temporomandibular, creando así un problema a largo plazo que afectan la calidad de vida de aquellas personas que las padecen. Actualmente no existe tratamiento curativo para dichas patologías, aunque sí de tipo paliativo, que en muchas ocasiones tienen efectos secundarios en el tiempo o una limitación en su efectividad y eficacia, por lo que se hace necesario buscar alternativas con la implementación de terapias regenerativas para el tratamiento de aquellas enfermedades que afectan el sistema musculoesquelético. En muchos estudios se discute sobre el papel fundamental que cumple el zinc y el estroncio en la génesis de tejido tanto cartilaginoso como óseo, así como la relevancia de incorporarlos con diversos biomateriales en procedimientos de regeneración, sin embargo, este tema no es claro aún y requieren más atención por parte del clínico. El objetivo de este artículo es determinar la función cumplen el zinc y el estroncio en los procesos de regeneración del hueso y el cartílago desde una visión molecular y celular aplicada a la práctica clínica, con el fin de obtener nuevas alternativas en el tratamiento de diversas patologías y alteraciones musculoesqueléticas que mejoren las condiciones de salud oral de los pacientes, además de, contar con la revisión que nos aproxime a comprender los mecanismos de acción de diferentes moléculas que incorporadas a los biomateriales compatibles con el tejido duro y blando mejoren las condiciones biológicas para la regeneración.
Introduction. The differential management of anchorage and the acceleration of tooth movement are some of the current greatest challenges for orthodontists. Diverse techniques and devices to reinforce anchorage and increase the rate of tooth movement have been proposed. Whether micro-osteoperforations (MOPs) can be used for both purposes is currently investigated. Objectives. To propose and describe a new technique for biological anchorage, which involves six MOPs performed every four weeks, and to present its results in a clinical case of upper premolar extraction. Intervention. In a dental class II patient who met the selection criteria, three MOPs both on the buccal and palatine sides on the intervention side were performed on the extraction area following the protocol described. No MOPs were performed on the control side. The allocation of the intervention was randomised. The MOPs were performed three times at an interval of four weeks. A

-inch stainless steel wire was activated with calibrated NiTi springs. The three-dimensional movement of the first molars and upper canines was evaluated. In addition, the comfort, periodontal status, and canine root resorption of the patient were evaluated. Results. Clinical and radiographic results suggest that the MOPs had a positive effect in reducing the loss of biological anchorage of the posterior sector and in the rate of canine tooth movement, without damaging changes in the soft and hard tissues. Conclusion. The proposed protocol involving six MOPs every four weeks improved the behaviour of biological anchorage and increased distalization on the intervention side in this clinical case.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
