RESUMEN

El torus mandibular es un crecimiento exofítico óseo benigno en la parte interna de la mandíbula, generalmente presente en ambos lados. Su etiología se relaciona a diversos factores como la herencia, grado de estrés, factores ambientales, nutricionales y trauma oclusal. Puede causar problemas funcionales y estéticos, como dificultad en la pronunciación, mal aliento, molestias al comer con prótesis mal adaptadas y ulceraciones. En la mayoría de los casos no es necesario el tratamiento, excepto cuando se requiere para mejorar la función protésica o solucionar problemas funcionales. En este artículo presentamos la situación clínica que describe la escisión exitosa del torus mandibular bilateral en un paciente de 57 años para la posterior rehabilitación protésica. La escisión del torus mandibular bilateral es un procedimiento seguro y predecible que ayuda a prevenir complicaciones protésicas y biológicas, mejorando la estabilidad y la función del sistema estomatognático (AU)

The mandibular torus is a benign bony exophytic growth in the inner part of the mandible, usually present on both sides. Its etiology is related to various factors such as heredity, degree of stress, environmental and nutritional factors, and occlusal trauma. It can cause functional and aesthetic problems, such as difficulty in pronunciation, bad breath, discomfort when eating with ill-fitting prostheses, and ulcerations. In most cases, treatment is not necessary, except when it is required to improve prosthetic function or solve functional problems. In this article we present the clinical situation that describes the successful excision of the bilateral mandibular torus in a 57-year-old patient for subsequent prosthetic rehabilitation. Bilateral mandibular torus excision is a safe and predictable procedure that helps prevent prosthetic and biological complications, improving the stability and function of the stomatognathic system (AU)

RESUMEN

Surgical intervention is a key element in the management of patients diagnosed with mucormycosis. A retrospective cohort study was carried out, in which patients with a proven diagnosis of mucormycosis were evaluated over a period of 10 years, according to the MSGERC criteria. A descriptive analysis of the clinical characteristics, comorbidities, imaging, and microbiology studies, as well as medical and surgical treatment and the type of prosthesis was carried out. A total of 22 cases were identified, of which 54.5% (n = 12) of the population were men. Furthermore, 77.2% (n = 17) of the population had diabetes mellitus. The main antifungal treatment implemented was liposomal amphotericin B (77.2%, n = 17). The most affected structures in our patients were the paranasal sinuses (n = 18; 81%), followed by the maxilla and orbit (n = 15; 68%), nose (n = 12; 54%), central nervous system (n = 11; 50%), and skin and soft tissues (n = 2; <1%). Of the total population, 59.09% (n = 13) of patients underwent maxillofacial surgery, of which 61.53% (n = 8) required some type of prosthetic rehabilitation. Orbital exenteration and maxillectomy were the most frequent surgeries, accounting for 69.23% (n = 9), while skull base drainage was performed in four patients (30.76%). Of the total number of patients (n = 22), eight died (36.36%). Appropriate surgical management according to the affected structures, considering not only increasing the patient's survival, but also considering the aesthetic and functional consequences, will require subsequent rehabilitation.

RESUMEN

OBJECTIVES: To investigate the association between different types of dental prostheses (and residual dentition) and oral health-related quality of life (OHRQoL). METHODS: A population-based study with a representative sample of adults and older adults in Uruguay (2010-2011). The dependent variable was the score on the oral impact on daily performance (OIDP), and the main predictor was the pattern of tooth loss and prosthesis use. Covariates included sex, age, socioeconomic status, education, missing teeth, pain and decayed teeth. Negative binomial regression was used. RESULTS: The sample comprised 762 participants. Those participants not wearing a prosthesis and with extensive tooth loss had a mean OIDP of 3.1 (95% CI = 1.6-6.2), while those wearing removable partial dentures (RPD) and having <12 missing teeth had a mean OIDP of 3.6 (95% CI = 1.3-10.0). Participants with a free-end saddle had the highest mean OIDP, at 4.9 (95% CI = 2.0-12.1). For participants with ≤12 missing teeth, any additional missing tooth was associated with an 11% higher OIDP score. Participants who wore RDPs reported fewer impacts on OHRQoL if they had extensive tooth loss or anterior tooth loss than those with a free-end saddle, or who had lost fewer teeth. CONCLUSIONS: The use of RPDs is associated with better OHRQoL. These findings may be valuable in clinical practice and prosthetic planning.

RESUMEN

BACKGROUND: The main objective of this systematic review was to present the outcomes of the treatment with zygomatic implants (ZIs) in the rehabilitations of atrophic upper jaw. FINDINGS: An electronic database search in PubMed, along with a manual search, taking into account language and study period, was performed by two observers; any type of clinical trial and series that included the use of ZIs was used. In the search strategy, the following search terms were used: zygom* AND dental (Implant OR implants) AND edentulous NOT (biomechanic* OR finite element) NOT cadaver. The search was limited to English language, full text, and humans. Literature reviews and clinical case reports were not considered. Forty-two articles published between March 2003 and April 2019 were included in this analysis. The cases of 1247 patients were recovered; these patients received 2919 ZIs. Fifty-two ZIs were removed during the follow-up time. The survival rate of these implants was 98.22%, with a minimum follow-up of 1 month and a maximum of 228 months. Different surgical techniques were used to place ZIs; however, the intrasinusal technique was the most used (23 studies). Post-surgical sinusitis was the most common complication reported in the studies (39 cases). CONCLUSIONS: Based on this review, ZIs were commonly used for rehabilitation of patients with atrophic upper jaw. The survival rates presented were high, and the surgical technique is dependent on the professional experience and the local anatomy. However, it needed additional clinical evidence on bone resorption, esthetic outcomes, and physiological characteristics.

Introducción: La pérdida dentaria tiene consecuencias en la apariencia y en la función fisiológica general del adulto mayor, lo cual constituye un problema aún no resuelto en la República Bolivariana de Venezuela. Objetivo: Describir la morbilidad en adultos mayores con pérdida de dientes permanentes. Método: Se realizó un estudio descriptivo, observacional y de corte transversal en la Clínica Simón Bolívar del municipio de Diego Ibarra, perteneciente al estado venezolano de Carabobo, desde enero hasta junio del 2016. El universo estuvo constituido por 100 adultos mayores de 60 años y más, ambos sexos y desdentados parciales o totales. Las variables analizadas fueron edad, sexo, higiene bucal, número de dientes permanentes perdidos, así como el tipo de aparatología protésica requerida. Se emplearon las frecuencias relativa y absoluta como medidas de resumen. Resultados: Se encontró que 73,0 % de los ancianos perdieron sus dientes por caries dental, siendo las féminas y el grupo de 60-64 años de edad el más afectado. Asimismo, predominaron la higiene bucal deficiente y la necesidad de prótesis parcial. Conclusiones: Existió una elevada morbilidad en los adultos mayores con pérdida dentaria, lo cual afectó su funcionalidad, estética y autoestima, que de no ser corregida pudiera provocar consecuencias importantes en la cavidad bucal y en el resto del cuerpo, sin olvidar la prevención o detección precoz de cualquier otra enfermedad bucal que la genere.

Introduction: Dental loss has consequences in the elderly general physiologic function and appearance, that constitutes an unsolved problem in the Bolivian Republic of Venezuela. Objective: To describe the morbidity in elderly with loss of permanent teeth. Method: A descriptive, observational and cross-sectional study was carried out in Simón Bolívar Clinic from Diego Ibarra municipality, belonging to Carabobo in Venezuela, from January to June, 2016. The universe was constituted by 100 elderly of 60 years and more from both sexes and partially or totally toothless. The analyzed variables were age, sex, oral hygiene, number of lost permanent teeth, as well as the type of prosthesis required. The relative and absolute frequencies were used as summary measures. Results: It was found that 73.0 % of the elderly lost their teeth due to dental decay, being women and the 60-64 age group the most affected one. Also, the poor oral hygiene and the necessity of partial prosthesis prevailed. Conclusions: A high morbidity existed in elderly with dental loss, which affected their functionality, aesthetics and self-esteem that could cause important consequences in the oral cavity and in the rest of the body if it is not corrected, without forgetting the prevention or early detection of any other oral disease that generates it.

RESUMEN

OBJECTIVE: To develop a budgetary impact analysis regarding the possibility of offering complete upper and lower dentures to an eligible population of elderly people (above 65 years) in the São Paulo state, Brazil. METHODS: The proportion of eligible population was calculated by assessing the prevalence of edentulous (upper and lower arch) and by defining the eligible group (public health system users). The budgetary impact analysis was designed under the following scenario: 5-year time horizon (2018-2022), prospect of municipal expenses with prostheses, and additional progressive incorporation of technology (upper and lower dentures) at an annual rate of 10%, 15%, 20%, 25%, and 30%. Sensibility analysis was performed in 3 different situations (reference, more pessimistic, and more optimistic) based on the calculation of spending through assessed demand and epidemiological demand. RESULTS: The municipal cost for each denture, already discounted the value transferred by the union for this procedure, was R$50.97. The incremental impact on the budget measured by the epidemiological demand relative to assessed demand was approximately R$59 141 510 over 5 years, meaning an impact of 0.08% (0.01% more optimistic; 0.13% more pessimistic) of the "medium and high complexity care" budget and 0.09% (0.03%-0.14%) of the primary care budget. CONCLUSION: The budgetary impact of increasing the oral rehabilitation with complete dentures for elderly population in the São Paulo state is low relative to the expenses with primary or specialized care budgets. In addition, incorporation of denture rehabilitation would be feasible, according to the financial availability and priorities of each municipality.

RESUMEN

Ameloblastoma is an aggressive odontogenic tumor which typically occurs between third and fourth decade of life that often needs resective approach. Immediate reconstruction may show better results. The treatment of multicystic ameloblastoma in the mandible being a rare case that occurred in the late second decade of life, which was surgically removed along with the affected teeth with safety margins, and the region was immediately reconstructed using a vascularized graft, removed from the fibula. Its integration, in combination with osseointegrated dental implants and fixed implant-supported prostheses, restored chewing function and esthetics. After 6 years from fibular graft and 24 months of dental implants, an excellent outcome was observed, with oral health and normal functions properly restored, and the immediate reconstruction of the mandible in resective cases, associated with oral rehabilitation with dental implants, may be considered a suitable treatment option.

RESUMEN

La fisura labiopalatina consiste en la falta de fusión de los procesos palatinos y labial durante el desarrollo embrionario. Estos pacientes presentan una comunicación buconasal, alteraciones dentarias de forma, tamaño y posición, y un deficiente desarrollo del maxilar. Su tratamiento requiere un trabajo de equipo multidisciplinar, ya que afecta funciones básicas que comprometen su calidad de vida, como comer, hablar o relacionarse socialmente. Aunque la cirugía primaria soluciona mayormente esta anomalía, algunas veces persiste la comunicación entre las cavidades bucal y nasal, lo que se conoce como comunicación o fístula buconasal. Esto supone una mayor dificultad en el cierre quirúrgico, siendo a veces imposible de cerrar a través de la cirugía. En tales casos, la obturación de dicha fístula a través de una prótesis otorga una solución de bajo costo para el paciente y con resultados óptimos a corto y mediano plazo. El objetivo de este artículo es exponer casos de rehabilitación protésica en pacientes con fisura labiopalatina y fístula buconasal posterior al tratamiento quirúrgico.

Cleft lip and palate is the lack of fusion of the palatal and labial processes during embryonic development. Patients are characterised by the presence of buconasal communication, dental alterations, and poor development of the maxilla. Treatment requires multidisciplinary team work, due to the impact on basic functions such as eating, talking or interacting with other people, and even compromising their quality of life. Although primary surgery mostly solves this anomaly, sometimes communication between the oral and nasal cavity persists (called communication or buconasal fistula). This leads to greater difficulty to surgically close it, being impossible in some cases. In these cases, the closure using a prosthesis provides a low-cost solution for the patient, with an optimal result in the short and medium term. The aim of this article is to present cases of prosthetic rehabilitation in patients with cleft lip and buconasal fistula after surgical treatment.

RESUMEN

As fenestrações das paredes alveolares são relativamente comuns durante o procedimento cirúrgico para instalação de implantes. O objetivo do presente trabalho foi relatar um caso clínico de reconstrução de fenestração peri-implantar imediatamente após a instalação de implante osseointegrável, através de enxerto ósseo autógeno em bloco obtido do ramo mandibular. Paciente do sexo masculino procurou o Departamento de Cirurgia e Clínica Integrada para trocar sua prótese parcial removível classe IV de Kennedy por prótese parcial fixa implantossuportada. Foram instalados dois implantes nos espaços protéticos correspondente aos dentes 12 e 21. Houve uma fenestração peri-implantar da parede vestibular durante a instalação do implante correspondente ao dente 12, que foi reconstruídapor meio de enxerto autógeno em bloco obtido do ramo mandibular e fixado por meio de parafuso bicortical. Após seis meses de concomitante período de incorporação do enxerto ósseo autógeno e osseointegração, iniciou-se o processamento para confecção da prótese parcial fixa implantossuportada. Diante da reabilitação protética alcançada, concluiu-se que o enxerto ósseo autógeno obtido da área doadora ramo mandibular constitui uma alternativa segura e eficaz para reconstrução de defeitos peri-implantares em forma de fenestração óssea...

Alveolar wall fenestrations are common during implant placement. The aim of this paper is to report a case where a peri-implant bone fenestration was reconstructed immediately after implant placement by an autogenous mandibular bone block. A male patient was referred to the Department of Surgical and Integrated Clinics to substitute his Kennedy´s Class IV removable partial denture for an implantsupported fixed prosthesis. A peri-implant bone fenestration at the buccal wall was seen at the region of 12, being reconstructed by a mandibular bone block secured by a bicortical screw. Six months later the surgical procedures, an implant-supported complete fixed partial prosthesis was developed. The autogenous bone block harvested from the mandibular ramus was a safe alternative to reconstruct the peri-implant bone defect such as fenestration types...

RESUMEN

A intrusão dentária é um movimento extremamente requisitado na Ortodontia, quando um dente apresenta-se extruído em relação aos seus adjacentes por perda de antagonista, por desgaste dentário ou fratura e também nos casos de mordidas abertas, nas quais se deseja a intrusão de todo o bloco posterior com a intenção de fechar a mordida aberta anterior. Esse artigo visa estabelecer critérios de escolha para a eleição de procedimentos clínicos baseados na fisiologia do periodonto e na mecânica empregada, ficando restrito aos movimentos individuais ou de dois dentes, não tendo, portanto, o objetivo de se aprofundar nos tratamentos de mordidas abertas, assunto esse com vasto material disponível na literatura.

The dental intrusion is extremely required in Orthodontics, when a tooth presents extruded in relation to its adjacent caused due the loss of antagonist, tooth wear or even fracture, and also in cases of open bite in which the intrusion of posterior block may help closing the anterior open bite. This article aims to establish selection criteria for the election of clinical procedures based on the physiology of the periodontium and mechanics employed, being restricted to individual movements or two teeth, therefore not having the purpose of delving into the open bite treatments, which has dense report in the literature.

RESUMEN

La rehabilitación de pacientes con secuelas de labio y paladar hendidos todavía sigue siendo un reto para los profesionales de la salud, tanto desde el punto de vista quirúrgico como del protésico. Estos pacientes necesitan de un tratamiento multidisciplinario que ofrezca la mejor alternativa de rehabilitación para el paciente. En este artículo presentamos la rehabilitación integral de un paciente con secuelas de labio y paladar hendidos (pérdida de la dimensión vertical, colapso nasal, defecto del labio superior, discrepancia del maxilar y la mandíbula, fístulas oro-antrales y ausencia de incisivos anteriores superiores) por medio de una sobredentadura modificada (sin hacer tratamiento endodóntico). El resultado estético y funcional con este tipo de tratamiento fue satisfactorio y se realizó en un periodo corto de tiempo.

Rehabilitation of patients suffering from cleft lip and palate surgery sequels is still a challenge for health professionals related to both surgical and prosthetic fields. These patients require a multi-disciplinary treatment able to offer the best possible rehabilitation alternative. The present article presents a case of total rehabilitation of a patient with sequels to cleft lip and palate surgery (loss of vertical dimension, nasal collapse, upper lip defect, upper and lower jaw discrepancies, oro-antral fistulae, absence of upper incisors) by means of a modified over-denture (with absence of endodontic treatment). Esthetic and functional results achieved with this treatment were satisfactory as well as achieved in a short period of time.

RESUMEN

This article describes the treatment of a 61-year-old man who had a completely edentulous maxillary arch and partially edentulous mandibular arch. The patient was orthodontically treated to correct an anterior crossbite by distalization of the mandibular teeth using a removable prosthesis serving as an anchorage unit. Subsequently, the patient received two zygomatic implants, five conventional implants in the maxillary arch, and six conventional implants in the mandibular arch. By the end of treatment, the convexity of the facial profile improved, and esthetic and functional occlusion was established.

RESUMEN

Introducción: la masticación constituye un proceso fundamental en la función digestiva, considerándose como su fase inicial. Objetivo: determinar factores de riesgo del desdentamiento y la asociación de trastornos del tracto digestivo superior con desdentamiento no rehabilitado con prótesis oportunamente. Método: cien pacientes entre 40 y 65 años, 50 desdentados y 50 dentados, fueron interrogados y examinados con una encuesta en la Facultad de Estomatología entre 2007-2009. Resultados: las odontopatías, poca educación en salud dental, escolaridad, higiene oral, acceso a servicios dentales y ancianidad, mostraron alto riesgo del desdentamiento significativo, p = 0.05. Se encontraron diferencias porcentuales elevadas a favor de los desdentados con significación clínica y estadística, p = 0.05, en tener síntomas digestivos, más de 3 síntomas, regurgitación, disfagia, dolor retro-esternal, pirosis, plenitud gástrica y síntomas post-desdentamiento. Los desdentados fueron 7.2 años más añosos, tuvieron 2.3 más síntomas digestivos en medias, y estuvieron 12 meses más sin rehabilitación protésica en mediana, que los íntegros dentarios, con significación estadística, p = 0.05. Los desdentados mostraron asociación entre demora de rehabilitación protésica de 25 a 144 meses, tener 3 síntomas o más (p=0.051), y padecer disfagia, pirosis y acidez estadísticamente significativa, p = 0.05. Conclusiones: se confirmaron factores de riesgo y se halló asociación estadística entre desdentamiento, tiempo sin prótesis y síntomas del tracto digestivo superior(AU)

Introduction: Mastication is considering an essential proceeding on digestive function, even the first phase of it. Objective: To determine the risk factors for teeth loss and its association with disorders of the upper digestive tract due to a late prosthetic rehabilitation. Methods: One-hundred patients aged between 40 and 65 years old, (50 edentulous patients and 50 with complete dentition), were interviewed and assessed at the Faculty of Dentistry, University of Medical Sciences Havana, 2007-2009. Results: The occurrence of odontopathies, deficient dental health education, educational level, oral hygiene, access to dental services and advanced age were found to be risk factors for significant tooth loss, p = 0.05. Statistically and clinically significant differences (p = 0.05) favouring the edentulous patients were found with regards to digestive symptoms, more than 3 symptoms, regurgitation, dysphagia, retrosternal pain, pyrosis, repletion, and late tooth loss. Edentulous patients were 7.2 years older, showed on average 2.3 more digestive symptoms and were 12 months longer without prosthetic rehabilitation (median), as compared to patients with complete dentition (p = 0.05). In edentulous patients, a statically and clinically significant association was found between a delay of 25-144 months in starting prosthetic rehabilitation and the appearance of 3 or more symptoms (p=0.051), dysphagia, pyrosis and heartburn (p = 0.05). Conclusions: Several risk factors were confirmed and a statistical association was found between tooth loss, time without prosthetic treatment and symptoms of the upper digestive tract(AU)

Conclusiones: Se confirmaron factores de riesgo y se halló asociación estadística entre desdentamiento, tiempo sin prótesis y síntomas del tracto digestivo superior.

Introduction: Mastication is considering an essential proceeding on digestive function, even the first phase of it. Objective: To determine the risk factors for teeth loss and its association with disorders of the upper digestive tract due to a late prosthetic rehabilitation. Methods: One-hundred patients aged between 40 and 65 years old, (50 edentulous patients and 50 with complete dentition), were interviewed and assessed at the Faculty of Dentistry, University of Medical Sciences Havana, 2007-2009. Results: The occurrence of odontopathies, deficient dental health education, educational level, oral hygiene, access to dental services and advanced age were found to be risk factors for significant tooth loss, p = 0.05. Statistically and clinically significant differences (p = 0.05) favouring the edentulous patients were found with regards to digestive symptoms, more than 3 symptoms, regurgitation, dysphagia, retrosternal pain, pyrosis, repletion, and late tooth loss. Edentulous patients were 7.2 years older, showed on average 2.3 more digestive symptoms and were 12 months longer without prosthetic rehabilitation (median), as compared to patients with complete dentition (p = 0.05). In edentulous patients, a statically and clinically significant association was found between a delay of 25-144 months in starting prosthetic rehabilitation and the appearance of 3 or more symptoms (p=0.051), dysphagia, pyrosis and heartburn (p = 0.05). Conclusions: Several risk factors were confirmed and a statistical association was found between tooth loss, time without prosthetic treatment and symptoms of the upper digestive tract.
