Oclusión basada en evidencia: rompiendo paradigmas / Occlusion based on evidence: breaking paradigms

La odontología basada en evidencias es una metodología que busca que las decisiones clínicas diarias que toman los profesionales en estomatología se encuentren fundamentadas en la evidencia científica, en ella se integran las experiencias clínicas, las necesidades, las preferencias del paciente y la evidencia clínicamente relevante más actual analizada por pares. Estos pilares son parte del proceso en la toma de decisiones para la atención al paciente. La odontología basada en evidencias surge de las exitosas experiencias obtenidas con el desarrollo e implementación de la medicina fundamentada en pruebas, al aplicar el método científico en la evaluación, planificación y toma de decisiones de las prestaciones sanitarias, sobre todo a través de los estudios controlados. En general, toda la práctica odontológica ha tenido grandes avances basados en evidencias, con hechos verídicos comprobados, pero los conceptos fundamentales de oclusión no han tenido una mejora cimentada en el conocimiento científico, prueba de ello es que se siguen ocupando teorías y conceptos de las filosofías de oclusión en la rehabilitación de muchos pacientes, seguimos creyendo en mitos y sofismas que no han podido ser demostrados. En esta revisión, demostramos los grandes avances en los conceptos de oclusión e invitamos a todos los odontólogos a romper los paradigmas de la oclusión antigua sin evidencias científicas y a utilizar las herramientas del método científico en la práctica clínica odontológica (AU)

Evidence-based dentistry is a strategy that seeks to ensure that the daily clinical decisions made by the dental professional are based on scientific evidence. It integrates the clinical experience of the dentist, the needs and preferences of the patient, and the most current relevant clinical evidence. All three are part of the decision-making process for patient care. Evidence-based dentistry arises from the successful experiences obtained with the development and implementation of evidence-based medicine, applying the scientific method in the evaluation, planning and decision-making of health benefits, especially through controlled studies. In general, all dental practice has had great advances based on evidence, with proven true facts, but the fundamental concepts of occlusion have not had an improvement based on scientific knowledge, proof of this is that theories and concepts continue to be used. of the philosophies of occlusion in patient rehabilitation, we follow myths and sophisms that have not been demonstrated, in this review, we demonstrate the great advances in the concepts of occlusion and we know all dentists to break the paradigms of the old occlusion without scientific evidence (AU)

Several important issues concerning occlusal reconstruction / 华西口腔医学杂志

Occlusal reconstruction aims to restore the compromised dentition and rehabilitate its function; which is demanding and challenging, even to the well experienced prosthodontists. Analyzing the sophisticate clinical information gives fundamental validity to the subsequent treatment planning. In the whole process, the applied workflow should ensure the transmission of diagnostic information without compromise or error. Certain procedures predetermine the clinical outcome, and they should be given due attention. In this review, the key considerations, including analyzing the pathogenesis for the worn dentition, were briefly addressed to better understand the occlusal reconstruction.

Occlusal reconstruction for a patient with dentinogenesis imperfecta typeⅡ / 实用口腔医学杂志

Dentinogenesis imperfecta type II(DGI-Ⅱ)is a rare autosomal dominant hereditary disease.DGI-Ⅱ tooth is short and brittle. This article reports the occlusal reconstruction treatment with fixed partial denture and discusses the key points of treatment.

A clinical study of improved occlusal reconstructions to partial denture arches with seriously interlaced occlusion / 中国基层医药

Objective To investigate the effective and inexpensive therapy to partial denture arches with seriously interlaced occlusion. Methods Occlusal reconstructions with fixed and removable prosthesis were taken to cure partial denture arches with seriously interlaced occlusion. Masticatory efficiency was measured and X-rays of Schillers position were taken before and after therapy. Results After therapy masticatory efficiency was raised. And the function of TMJ was better. Conclusion Occlusal reconstruction with fixed and removable prosthesis is an effective way to cure partial denture arches with seriously interlaced occlusion.

Stress and displacement distribution of mandibular condyle advanced with Forsus under different occlusal reconstruction conditions / 医用生物力学

Objective To analyze changes of stress and displacement distribution of the mandibular condyle under different occlusal reconstruction conditions by using the Forsus, and to provide clinical reference for the application of the Forsus. Method The software Abaqus6.5 was employed to build the 3D finite element model of mandibular condyle for simulation. Under different occlusal reconstruction conditions, the distances of mandibular protraction were 3 mm, 4 mm, 5 mm, 6 mm and 7 mm and the mandibular's opening distances were got as 4 mm, 3.5 mm, 3 mm, 2.5 mm and 2 mm correspondingly. The stress, displacement and rotation trends of mandibula temporomandibular articulation were analyzed and the estimation of occlusal reconstruction contributing to the growth of the condyle was made. Results The 3D model showed that the maximum stress distributed on the mandibular condyloid process, sigmoid incisure of mandible and the posterior neck of condyle area under the five different conditions. With the increase of displacement in mandibular condyle, the stress increased slowly on the sigmoid incisure of mandible and the posterior neck of condyle area, but the stress still kept in the same order of magnitude (30 MPa). The stress distribution of mandibular condyloid process was in a steady state with no obvious stress concentration. The displacement of condyle in horizontal direction increased gradually and forward, and the displacement of condyle in vertical direction also increased gradually but downward. When the mandibular was stretched to the designed reconstructive location, the condyle moved downward. Conclusions The range of physiological occlusal reconstruction will not change the stress distribution trends of the condylar cartilage, even when the mandibular moves forwards in varying degrees. Considering the physiological nature of temporomandibular articulation and the growth of the condyle, when the mandibular retrusion is severe, it would be advisable by subsection protrusion.

Objective:To explore a new method and it's clinical efficiency of porcelain technique on severe tooth wear and dentition defect.Methods:The transitional occlusal pad restored the vertical dimension and centric relation.decreased TMD symptoms.The porcelain technique was used to reconstruct the occlusal relationship,their prognoses and patients' satisfactory were recorded.Results:45 patients suffered from serious dental abrasion,whose clinical symptoms got much better and masticatory efficiency improved significantly.Conclusion:Porcelain is an aesthetic and comfortable technique to improve patients' masticatory efficiency significantly which is similar to real tooth.

Physiotherapy and reconstruction for occlusal disorder after mistaken concrescence of maxillofacial fracture / 中华物理医学与康复杂志

Objective To analyze the reasons of the occlusal disorder after mistaken concrescence of maxillofacial fracture, to observe the effect of the physiotherapy for the masticatory movement and the masticatory efficiency after occlusal reconstruction with fixed prosthesis. Methods The reasons of occlusal disorder of 45 patients were analyzed by reviewing the case history and clinical examination. Ultrasound diathermy and laser irradiation were used to help improve masticatory movement. The fixed prosthesis was used to reconstruct the occlusal relationship. Masticatory efficiency was measured with the method of sift out before treatment, one month and one year after treatment. Results The main reason of occlusal disorder was the delay of treatment because of the other treatment of body after trauma. The physiotherapy was effective in improving the masticatory movement. Statistically analysis showed the significantly difference before and after occlusal reconstruction with fixed prosthesis ( P
