Fabricating a dual-material, vat-polymerized, additively manufactured static implant surgical guide: A dental technique.

Protocols with static computer-aided implant placement provide more tangible clinical advantages than conventional implant placement methods. A technique to manufacture a dual-material implant surgical guide by using a vat-polymerization printer is described. The implant surgical guide combined a resilient intaglio and hard exterior surface. The technique should minimize the clinical adjustments needed to ensure fit and improve patient comfort.

El reto del abordaje quirúrgico en la rehabilitación sobre un implante unitario en un caso de alto requerimiento estético del sector anterior. Descripción a propósito de un caso / The challenge of the surgical approach in the rehabilitation of a unitary implant in a case of high aesthetic requirements of the anterior sector. Case report

Objetivo: Describir de forma detallada el abordaje clínico basado en la evidencia científica actual de un implante postextracción con carga y provisionalización inmediata. Caso clínico: Se presenta el caso de una paciente mujer de 32 años de edad, que acude por presentar una posible fractura radicular del incisivo central superior izquierdo (ICSI), acompañada de la aparición de un absceso periodontal en la región del fondo de vestíbulo de dicho diente. Tras llevar a cabo la exploración clínica y radiológica, se establece que el pronóstico del ICSI es desfavorable para llevar a cabo un tratamiento conservador del mismo. Tras la valoración de las características clínicas del caso presente, el plan de tratamiento se inclinó por la realización de la exodoncia del ICSI con la colocación simultánea de un IOI postextracción y la carga inmediata con una prótesis provisional del mismo. Conclusiones: La rehabilitación sobre implantes en situaciones de pérdida dental en el sector anterior estético y en especial, en pacientes jóvenes, requiere un plan de tratamiento multidisciplinar en cuanto a la extracción del diente y colocación del IOI en la posición tridimensional correcta, existiendo diferentes aspectos a tener en cuenta para ello, especialmente el remanente óseo residual, la posición del margen gingival, así como la preservación y acondicionamiento de los tejidos duros y blandos periimplantarios mediante injertos y un manejo correcto de una prótesis provisional hasta conseguir un perfil de emergencia y contorno gingival ideal antes de la corona definitiva.

Objective: To describe in detail the clinical approach based on current scientific evidence for a post-extraction implant with immediate loading and provisionalisation. Clinical case: We present the case of a 32-year-old female patient who presented with a possible root fracture of the upper left central incisor (ULCI), accompanied by the appearance of a periodontal abscess in the region of the bottom of the vestibule of said tooth. After carrying out the clinical and radiological examination, it is established that the ULCI prognosis is unfavourable for carrying out conservative treatment of the tooth. After assessing the clinical characteristics of the present case, the chosen treatment plan was to extract the ULCI with the simultaneous placement of a post-extraction osseointegrated implant (OII) and immediate loading of a provisional prosthesis on the implant. Conclusions: Rehabilitation on implants in situations of tooth loss in the aesthetic anterior sector, especially in young patients, requires a multidisciplinary treatment plan in relation to tooth extraction and placement of the OII in the correct three-dimensional position. There are various aspects to be taken into account, particularly the residual remaining bone, the position of the gingival margin, as well as the preservation and conditioning of the peri-implant hard and soft tissues by means of grafts and proper handling of a provisional prosthesis until an ideal emergence profile and gingival contour is achieved before the final crown.

Patogénesis del dolor en la mucositis oral. Revisión de la literatura / Pathogenesis of pain in oral mucositis. Review of the literature

INTRODUCCIÓN: La mucositis oral es una lesión dolorosa que tiene lugar en la mucosa de la cavidad oral, normalmente su etiología se encuentra asociada a tratamientos farmacológicos en pacientes oncológicos. Se presenta como úlceras bien delimitadas cuya sintomatología dolorosa supone en ocasiones la suspensión del tratamiento oncológico o la alimentación por vía parenteral, siendo por tanto un efecto adverso importante, marcando el devenir en este tipo de terapias contra el cáncer. OBJETIVO: El objetivo del presente artículo es poner en relieve cómo se produce el dolor en esta patología que acontece en la mucosa de la cavidad oral. DISCUSIÓN: La mucositis oral se va a presentar tras una cascada de eventos biológicos que implican diferentes procesos moleculares tras el tratamiento con quimioterapia o radioterapia. El dolor en la mucositis oral puede poseer un componente inflamatorio y también un componente neuropático. En su fisiopatología, el dolor va a estar mediado por diferentes familias de receptores y factores. CONCLUSIÓN: La mucositis oral presenta un gran componente doloroso asociado, en el que cobran especial protagonismo en su aparición, las familias de los receptores y factores TRP, ET-1, TNF y ROS, entre otros. El conocimiento de la patogénesis del dolor en esta patología permitirá desarrollar terapéuticas contra el dolor en estudios futuros

INTRODUCTION: Oral mucositis is a painful lesion that occurs in the mucosa of the oral cavity. Its aetiology is usually associated with drug treatments in cancer patients. It presents as well-defined ulcers whose painful symptoms sometimes lead to the suspension of cancer treatment or parenteral nutrition. They therefore represent a significant adverse effect that marks the future in this type of cancer therapy. OBJECTIVE: The objective of this article is to highlight how pain occurs in this pathology that takes place in the mucosa of the oral cavity. DISCUSSION: Oral mucositis will occur following a cascade of biological events involving different molecular processes following treatment with chemotherapy or radiotherapy. Pain in oral mucositis may have an inflammatory component as well as a neuropathic component. In its pathophysiology, pain will be mediated by different families of receptors and factors. CONCLUSION: Oral mucositis has a large associated painful component, in which the families of TRP, ET-1, TNF and ROS receptors and factors, among others, play a major role in its appearance. Knowledge of the pathogenesis of the pain in this pathology will allow pain therapies to be developed in future studies

The challenge of the surgical approach in the rehabilitation of an anterior sector unitary implant in a case of high aesthetic requirements; case report

Objective: Provide a detailed description of the current evidence-based clinical approach to a post-extraction implant with immediate loading and provisionalisation. Clinical case: A 32-year-old female patient who attended for a possible root fracture of the upper left central incisor (ULCI), accompanied by a periodontal abscess at the bottom of the vestibule of the same tooth. A clinical and radiological examination established that the prognosis of the ULCI was unfavourable for conservative treatment. After evaluating the clinical features of the case, the treatment plan to extract the ULCI followed immediately by an osseointegrated implant (OII) and loading of a provisional prosthesis on the implant. Conclusions: Rehabilitation on implants in situations of tooth loss in the aesthetic anterior sector, especially in young patients, requires a multidisciplinary treatment plan to extract the tooth and insert an OII in the correct 3-dimensional position. Various aspects need to be taken into account for this, particularly the residual remaining bone, the position of the gingival margin and preservation and conditioning of the peri-implant hard and soft tissues by means of grafts and proper handling of provisional prosthesis, until an ideal emergence profile and gingival contour is achieved before the final crown.
