EPA Consensus Project Paper: Shifting from the "Analogic Virtual Patient" to the "Digital Virtual Patient" in Prosthodontics. A Scoping Review.

AIMS: To determine whether the use of single or combined mechanical and virtual articulators, as well as facebows, jaw motion trackers, face scanners, and related devices, actually improve the efficacy of the prosthesis obtained in terms of lifespan and patient-related outcomes. To coin the terms Analogic and Digital Virtual Patients (AVP and DVP) as an attempt to analyze, clarify and synthesize terminology and workflows related to previously so-called devices. MATERIALS AND METHODS: A scoping review was accomplished involving different databases. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA-ScR) checklist and JBI guidance were followed to extract data regarding the Population, Context and Concept established. RESULTS: Available literature on the efficacy of using devices and techniques related to both AVP and DVP workflows showed arguable study designs, great heterogeneity, and questionable quality. CONCLUSIONS: The terms AVP and DVP have been coined as a first step to clarify and simplify concepts and workflows related to the use of both mechanical and virtual articulators, as well as facebows, or facial and intraoral scanners, among others. This scoping review cannot claim that an AVP approach leads to more effective and efficient prosthetic restorations.

Impact of the coronavirus pandemic on maxillofacial trauma: A retrospective study in southern Spain.

BACKGROUND: The coronavirus pandemic has impacted health systems worldwide, with Spain being one of the most affected countries. However, little is known about the extent to which the effects of staying home, social distancing, and quarantine measures have influenced the epidemiology of patients with maxillofacial trauma. The aim of this study was to analyze the impact of the coronavirus pandemic on the incidence, demographic patterns, and characteristics of maxillofacial fractures in the largest hospital in southern Spain. MATERIAL AND METHODS: Data from patients who underwent surgery for maxillofacial fractures during the first year of the pandemic between 16 March 2020 and 14 March 2021 (pandemic group) were retrospectively compared with a control group during the equivalent period of the previous year (pre-pandemic group). The incidence was compared by weeks and by lockdown periods of the population. Demographic information, aetioloy, fracture characteristics, treatment performed, and days of preoperative stay were evaluated. Descriptive and bivariate statistics were calculated (p<0.05). RESULTS: During the first year of the pandemic, there was a 35.2% reduction in maxillofacial fractures (n=59) compared to the pre-pandemic year (n=91, p=0.040). A significant drop was detected during the total home lockdown period of the population (p=0.028). In the pandemic group, there was a reduction in fractures due to interpersonal aggressions, an increase in panfacial fractures, a significant increase in other non-facial injuries associated with polytrauma (p=0.037), a higher number of open reduction procedures with internal fixation, and a significantly longer mean preoperative stay (p=0.016). CONCLUSIONS: The first pandemic year was associated with a decline in the frequency of maxillofacial trauma and a change in the pattern and characteristics of fractures. Inter-annual epidemiological knowledge of maxillofacial fractures may be useful for more efficient planning of resource allocation and surgical practice strategy during future coronavirus outbreaks and population lockdowns.

Relación céntrica: revisión de conceptos y técnicas para su registro. Parte I / Centric relation: concepts revision and recording techniques. Part I

La relación céntrica ha sido objeto de disparidad de criterios en la odontología durante más de un siglo. A lo largo de este trabajo, vamos a exponer diferentes métodos usados tanto para obtener el registro, como para comprobar su certeza y corroborar la posición condilar. Dado que no existe evidencia científica en el tema, en este trabajo, revisaremos los estudios experimentales que aparecen en la literatura. Los hemos divididos en dos partes, la primera relacionada con la definición de relación céntrica y la segunda parte relacionada con técnicas de registro, posición condilar y la discrepancia entre relación céntrica y oclusión céntrica (AU)

The centric relation has been controversial on dentistry during more of one century. Along of this work, we are going to expose different methods to recording as checking the accuracy and condilar position. Given that there aren’t scientific evidence, in this work, we review the researches publicated. We have divided them into two parts; the first is related with the definition of centric relation and the second part is related with recording techniques, condilar position and centric relation- centric occlusion discrepancy (AU)

Inserción de un implante simultáneo a la extracción de un canino superior incluido / Insertion of a simultaneous implant in the extraction of an upper included canine

Presentamos el caso clínico de una paciente adulta con un canino superior incluido, en la que se llevó a cabo un plan de tratamiento multidisciplinar y secuencial quirúrgico-ortodóncicoprotésico. En un primer tiempo, se instauró un tratamiento ortodóncico con el que disponer de un espacio intercalar adecuado para la posterior reposición del canino superior. En un segundo tiempo, se realizó la extracción del canino incluido junto con un tratamiento combinado de regeneración ósea e inserción inmediata de un implante, para finalizar con la restauración protésica mediante una corona implantosoportada. Se revisa además la literatura al respecto y el estado actual del problema (AU)

We present a clinical case of an adult patient with an impacted upper canine, a multidisciplinary and sequential surgical-orthodontist-prosthetic treatment plan was made. In a first time, an orthodontic treatment was established in order to have a suitable space to a later upper canine replacement. In a second instance, the extraction of the canine was done, including a combined treatment of bone regeneration, with an immediate insertion of an implant. To conclude the treatment a prosthetic restoration with a crown supported on an implant was completed. Review of the literature was done in order to present the actual situation of the problem (AU)

Inflammatory papillary hyperplasia of the palate: treatment with carbon dioxide laser, followed by restoration with an implant-supported prosthesis.

Inflammatory papillary hyperplasia of the palate is a persistant non-neoplastic lesion that is normally caused by poorly fitting dentures and Candida infection. We describe a case that was managed primarily with topical miconazole, and complete removal of the old acrylic denture. A multidisciplinary approach between surgeon and prosthodontist was used that combined carbon dioxide laser followed by substitution of the old removable denture for a new implant-supported screw retained prosthesis. This avoided direct support of the prosthesis by the palatal mucosa and made oral hygiene easier. The treatment has resulted in complete remission and there has been no recurrence occurred during 3 years of follow-up.
