Título: Short-term use of resveratrol in alloplastic graft material applied with calvarial bone defects in rats
Fonte: Acta cir. bras;34(7):e201900704, 2019. tab, graf.
Idioma: en.
Resumo: Abstract Purpose: The effects of resveratrol administration on calvarial bone defects with alloplastic graft material was investigated for osteoinductive reaction and bone development in rats. Methods: Healthy male rats were randomly divided into 3 groups consisting of 10 rats. Groups were as follows: control (defect) group, defect + graft group, and defect + graft + resveratrol group. A calvarial bone defect was created in all groups, alloplastic bone grafts were applied to the defect in the 2nd and 3rd group, resveratrol (5 mg/kg/day) was added to the drinking water of the animals following graft application for 28 days in the 3rd group. Results: Increase in osteoclasts and necrotic changes were observed histopathologically in the control group. In the 2nd group, reduction of inflammation, congestion of blood vessels, increased osteblastic activity, osteoinductive effect, progression of osteocyte development and increased collagen fibers in connective tissue were observed. In the 3rd group, osteoblasts seemed to secrete bone matrix and accelerate osteoinductive effect with increased osteopregenitor activity and positive osteopontin and osteonectin expressions. Conclusion: Resveratrol treatment was thought to be an alternative and supportive drug for implant application by inducing new bone formation in the calvaral defect region as a result of short-term treatment.

Título: Action of a deproteinized xenogenic biomaterial in the process of bone repair in rats submitted to inhalation of cigarette smoke
Fonte: Acta cir. bras;33(4):324-332, Apr. 2018. tab, graf.
Idioma: en.
Resumo: Abstract Purpose: To investigate if the inorganic bovine bone matrix changes the bone formation in rats submitted to inhalation of cigarette smoke. Methods: Twenty Wistar rats were divided into two groups: Cigarette Clot Group (CCG), which in the inhalation chamber received the smoke of 10 cigarettes, 3 times a day, 10 minutes, for 30 days and had the surgical cavity filled by clot; Cigarette Biomaterial Group (CBG), submitted to the same inhalation technique but with the cavity filled by biomaterial. Results: In CCG there was a significant difference of new bone tissue in the analyzed periods (15 and 45 days), and in 15 days, there was 4.8 ± 0.42 of bone formed and 11.73 ± 0.59 (p <0.05) in 45 days. The CBG also showed a significant difference between the periods of 15 to 45 days, being respectively 6.16 ± 0.30 and 11.60 ± 0.61. However, when the groups were compared, within the same analyzed periods, a significant difference was observed only in the period of 15 days, with the new bone percentage being greater in the CBG. Conclusion: The bone matrix acted as an osteoinductive biomaterial, biocompatible and aided in the repair process, mainly in the initial period of recovery.

Título: Demineralized bone matrix and calcium-phosphate cement in bone regeneration in rats
Fonte: Acta cir. bras;33(4):354-361, Apr. 2018. tab, graf.
Idioma: en.
Resumo: Abstract Purpose: To compare bone regeneration in critical-sized defects in rat calvarium using demineralized bone matrix and calcium phosphate cement. Methods: Thirty Wistar rats were divided into 3 groups of 10 animals each. Two defects of 5-mm were made in the parietal bones of each animal. Group I had calcium phosphate cement placed in the experimental defect, Group II had filled with demineralized bone matrix and Group III had with the combination of the matrix and cement in equal parts. All animals had one defect left unfilled to serve as controls. Five animals in each group were sacrificed at 4 and 8 weeks. Histomorphometric analysis was used to quantify the amount of new bone within the defects. Results: The results showed that demineralized bone matrix-treated defects had significantly more new bone at 4 weeks compared to calcium phosphate cement-treated defects (p=0.03) and also had significantly more new bone at 8 weeks compared to unfilled defects (p=0.04). Conclusions: The demineralized bone matrix was superior to calcium phosphate cement in bone regeneration. It seems that calcium phosphate cement acted by inhibiting the osteogenesis when associated with a demineralized bone matrix and this combination should not be recommended.

Título: Potencial of different hydroxyapatites as biomaterials in the bone remodeling
Fonte: Acta cir. bras;33(9):816-823, Sept. 2018. tab, graf.
Idioma: en.
Resumo: Abstract Purpose: To analyze the therapeutic potentials of different hydroxyapatites used for the correction of bone defects in rats. Methods: Forty rats, male, albino wistar, were distributed in 4 groups. They were submitted to a 3.5 mm defect in tibia. They received low purity hydroxyapatite, Strontium hydroxyapatite and hydroxyapatite doped with gallium, having a seven day evaluation time. Histopathology slides were stained with hematoxylin-eosin, for morphological evaluation. Were analyzed inflammatory processes, necrosis, presence of osteoclasts and osteoblasts, presence of the material, presence of white cells, neovascularization and bone neoformation. Results: It was observed that the groups HAPSr and HAPGa, presented better results of trabecular bone, hyaline cartilage and bone marrow more organized. Conclusion: There was improvement in the repair of the bone defect produced, showing that these hydroxyapatites are effective osteoinductive, osteoconductive, osteintegrant agents and have biocompatibility, and may be indicated for use in defect repairs.

Título: Bioceramic cement in the filling of bone defects in rats
Fonte: Acta cir. bras;34(6):e201900601, 2019. tab, graf.
Idioma: en.
Resumo: Abstract Purpose To evaluate PBS®MCIMMO cement in the filling of bone defects. Methods Thirty-six adult male Wistar rats were divided into three groups of twelve individuals each (group 1, group 2 and group 3). In all groups, a bone failure in the femur was induced, 2.0 mm wide and 7.0 mm deep. In group 1, the PBS®MCIMMO cement was applied to the bone defect produced and a titanium implant (CONNECTION®) 1.5 mm thick and 6 mm long was installed. In group 2, only the PBS® CIMMO cement was installed. In group 3, only bone failure was performed. Kruskal Wallis tests were performed to compare the mean area among the three groups. Results In all comparisons, significance was observed for group 2 (p = 0.0014-0.0026). Conclusion The PBS®CIMMO cement induced bone neoformation, and integration between the newly formed bone, cement, and implant was observed.

Título: Comparison of morphological quantitative characteristics of the newly formed alveolar bone after the application of demineralized bone matrix and cortical bone allografts / Comparación de las características morfológicas cuantitativas del hueso alveolar recién formado después de la aplicación de matriz ósea desmineralizada y aloinjertos de hueso cortical
Fonte: Int. j. morphol;37(4):1509-1516, Dec. 2019. graf.
Idioma: en.
Resumo: The allografts were used to obtain sufficient alveolar bone tissue for proper dental implant placement. The objective of the present study was to evaluate the morphological and quantitative characteristics (cellular and collagen densities) of the newly formed alveolar bone with the application of cortical bone (CB) and demineralized bone matrix (DBM) allografts. Six samples of alveolar bone tissue from 5 patients (50 ± 6.3 years) were obtained after 6 months of application of the allografts and immediately before the placement of the dental implants. The samples were fixed (buffered formaldehyde, pH7.2), decalcified (EDTA 10 %) and histologically processed (HE and Picro-Sirius) for histologic analysis. Morphological analysis revealed presence of osteocytes and trabeculae in neoformed bone tissue near the allografts and absence of inflammatory and allergic cells; the remnants of CB were located mainly in the periphery of the bone tissue and the remnants of DBM were more incorporated into the tissue. Osteogenitor cells were observed around the remaining material. The cell density was not modified in newly formed bone tissue with the application of both allografts as compared to mature bone tissue. The density of the type I and III collagens present in the osteoids interspersed with the remainder of the materials showed a tendency to increase in the samples treated with DBM. It was concluded that by the histological characteristics observed both grafts were biocompatible, however the bone treated with DBM presented better incorporation and a tendency of increase of the collagen content in the remnant region of the allografts.

Los aloinjertos son utilizados para obtener tejido óseo alveolar apropiado para la colocación correcta del implante dental. El objetivo de este trabajo fue evaluar las características morfológicas y cuantitativas (densidades celulares y de colágeno) del hueso alveolar recién formado con la aplicación de aloinjertos de hueso cortical (CB) y matriz desmineralizada de hueso (DBM). Seis muestras de tejido óseo alveolar fueron obtenidas de 5 pacientes (50 ± 6,3 años) después de 6 meses de aplicación de los aloinjertos e inmediatamente antes de la colocación de los implantes dentales. Las muestras fueron fijadas (formaldehído tamponado, pH 7,2), descalcificadas (EDTA al 10%) y procesadas histológicamente (HE y Picro-Sirius) para el análisis histológico. El análisis morfológico reveló la presencia de osteocitos y trabéculas en el tejido óseo neoformado cerca de los aloinjertos y la ausencia de células inflamatorias y alérgicas; los remanentes de CB se ubicaron principalmente en la periferia del tejido óseo y los remanentes de DBM se incorporaron más en el tejido. Se observaron células osteogenitoras alrededor del material restante. La densidad celular no se modificó en el tejido óseo recién formado con la aplicación de ambos aloinjertos en comparación con el tejido óseo maduro. La densidad de los colágenos de tipo I y III presentes en los osteoides intercalados con el resto de los materiales mostró una tendencia a aumentar en las muestras tratadas con DBM. Se concluyó que, debido a las características histológicas observadas, ambos injertos fueron biocompatibles, sin embargo, el hueso tratado con DBM presentó una mejor incorporación y una tendencia al aumento del contenido de colágeno en la región remanente de los aloinjertos.

Idioma: en.
Resumo: ABSTRACT Jawbone reconstruction after tumor resection is one of the most challenging clinical tasks for maxillofacial surgeons. Osteogenic, osteoinductive, osteoconductive and non-antigenic properties of autogenous bone place this bone as the gold standard for solving problems of bone availability. However, the need for a second surgical site to harvest the bone graft increases significantly both the cost and the morbidity associated with the reconstructive procedures. Bone grafting gained an important tool with the discovery of bone morphogenetic proteins in 1960. Benefit of obtaining functional and real bone matrix without need of second surgical site seems to be the great advantage of use bone morphogenetic proteins. This study analyzed the use of rhBMP-2 in unicystic ameloblastoma of the mandible, detailing its structure, mechanisms of cell signaling and biological efficacy, in addition to present possible advantages and disadvantages of clinical use of rhBMP-2 as bone regeneration strategy.

RESUMO A reconstrução óssea dos maxilares após ressecções tumorais é uma das tarefas mais difíceis para o cirurgião maxilofacial. As propriedades osteogênicas, osteoindutoras, osteocondutoras e não antigênicas do osso autógeno o colocam como o padrão-ouro para a solução de problemas de disponibilidade óssea. Entretanto a coleta do enxerto ósseo necessita de um segundo sítio cirúrgico, aumentando significativamente o custo e a morbidade associados ao procedimento reconstrutivo. A enxertia óssea ganhou uma excelente ferramenta com a descoberta das proteínas ósseas morfogenéticas na década de 1960. O benefício da obtenção de matriz óssea verdadeira e funcional, sem a necessidade de um segundo sítio cirúrgico, parece ser a grande vantagem do uso das proteínas ósseas morfogenéticas. Neste contexto, o objetivo deste estudo foi analisar a utilização da rhBMP-2 na regeneração óssea de ameloblastoma mandibular unicístico, detalhando sua estrutura, seus mecanismos de sinalização celular e sua eficácia biológica, além de apresentar potenciais vantagens e desvantagens da utilização clínica das rhBMP-2, enquanto estratégia regenerativa.

Idioma: es.
Resumo: Objetivos: demostrar la relación del uso del sustituto óseo con un menor tiempo de consolidación y la menor agresión al paciente. Material y Métodos: Estudio retrospectivo y comparativo, de dos grupos de pacientes. Grupo A: 13 pacientes (8 hombres y 5 mujeres) con gonartrosis medial y genu varo, tratados con osteotomías de apertura sin sustituto óseo, edad media 53 años. Grupo B: 15 pacientes (12 hombres y 3 mujeres) con osteotomías de apertura con la utilización de sustituto óseo, edad media 48 años. Ambas osteotomías se realizaron con placas tipo Puddu no bloqueadas. Se tomaron radiografías en el postoperatorio inmediato y cada 15 días, para tener un seguimiento de la consolidación en ambos grupos. Resultados: En el grupo que se utilizó el sustituto óseo, el tiempo de consolidación fue menor con un promedio de 35 días acortando el tiempo de reinserción a las actividades cotidianas. Conclusion: El uso de sustituto óseo en osteotomía de apertura logra conseguir una consolidación pronta, acortando los tiempos de rehabilitación y de reinserción laboral.

Título: Osteotomía valguizante tibial alta: comparación de resultados con el uso de aloinjerto y sustituto óseo / High tibial osteotomy. Allograft versus bone substitute
Fonte: Artrosc. (B. Aires);21(3):89-94, sept. 2014. ilus, tab, graf.
Idioma: es.
Resumo: Introducción: El relleno de la brecha producido por una osteotomía tibial proximal valguizante de apertura (OTA), se encuentra en constante discusión, dado los resultados dispares obtenidos por los distintos autores. El objetivo del siguiente trabajo fue comparar los resultados tanto radiológicos como clínicos con el uso de sustituto óseo y aloinjerto. Materiales y Método: Entre 2009 y 2012, se realizaron 34 OTA. La muestra fue dividida en dos grupos, 15 pacientes en los cuales se había utilizado sustituto óseo (SO) y 19 pacientes en los que se colocó aloinjerto óseo estructural (AI). El grado de artrosis fue estadificado preoperatoriamente según la clasificación de Ahlbãck e intraoperatoriamente estadificamos las lesiones de cartílago según la clasificación de Outerbridge. El análisis clínico se realizó mediante la Escala de la Sociedad de Rodilla (Knee Society Score) y la Escala de Oxford. El seguimiento del tiempo de consolidación, eje anatómico, eje mecánico y mantenimiento de la corrección (diferencia en milímetros) se realizó mediante radiografías con un seguimiento mínimo de un año. Resultados: La unión ósea ocurrió en la totalidad de las osteotomías, siendo el tiempo de consolidación ósea de 4,3 meses (50 días – 6 meses) en el grupo SO y de 3,2 meses (40 días – 5 meses) en el grupo AI (p=0,7). Se obtuvo una mejoría promedio del Knee Score y del Knee function de 20,3 y de 14,8 puntos respectivamente en el grupo SO y de 21,3 y 19,1 puntos en el grupo AI. La evaluación con el Oxford Score evidencio una mejoría promedio en el grupo SO de 21 puntos y de 29 puntos en el grupo AI. Por lo referido anteriormente no encontramos diferencias significativas entre ambos grupos en la evaluación funcional de los pacientes. Tuvimos dos casos descriptos de perdida de corrección que ocurrieron en el grupo SO, a diferencia del grupo AI en el que no apareció ninguna perdida de corrección no siendo esta una diferencia estadísticamente significativa (p=0,09). Conclusión: Ambos materiales tienen resultados clínicos e índices de consolidación comparables, pero con un mayor riesgo de pérdida de corrección de las osteotomías con sustituto óseo. Nivel de Evidencia: IV

Introduction: Given the disparate results obtained by different authors concerning the material to fill the bone gap produced by an opening high tibial osteotomy (HTO) the decision remains controversial. Good and very good results have been reported with bone substitute wedges and allograft, which avoid the inconveniences of autologous grafts use. The purpose of this study was to compare both radiological and clinical results using allograft and bone substitute. Material and Methods: We retrospectively analyzed 34 opening wedge HTO filled with allograft or bone substitute (from 2009 to 2012). We divided the sample into two groups: BS (Bone substitute) group was conformed by 15 patients and the AG (Allograft) group with 19 patients. The degree of osteoarthritis was staged preoperatively and intraoperatively we stratified condral lesions according to the classification of Ahlbãck and Outerbridge respectively. The clinical analysis was performed using the Knee Society Score and Oxford Knee Score. We analyzed time to consolidation, anatomical and mechanical axis and loss of correction (measured in millimeters) using X-rays. Results: Union occurred in every osteotomy, mean time was of 4,3 months in the BS group and 3,2 months in the AG group (p: 0,7). The knee society score (Knee Score and Knee function) were 20,3 and 14,8 points respectively in the BS group, and 21,3 and 19,1 in the AG group. The evaluation with the Oxford Score was 21 points in the BS group and 29 in the AG Group. As mentioned above, we did not found significant differences between groups in the functional assessment of patients. We had two cases of loss of correction in the BS group, and none in the AG group (p = 0.09). Conclusion: The results shows that there was no statistical difference between the two groups for overall complications. However, clinical results filling with bone substitute was less tolerated and increased the risk of loss of correction. Level of Evidence: IV

Resumo: The procedure of maxillary sinus lifting using autogenous bone was considered the reference standard choice for oral rehabilitation in cases of severe atrophic maxilla. However, it is not always a viable option, due to the limitations or morbidity caused by grafting techniques. This has led to the development of bone substitutes, which have been elaborated and improved. Choosing the best biomaterial becomes difficult due to the wide variety of bone substitutes. The aim of this article is to present some of these materials that are reported in the current scientific literature for maxillary sinus lifting.

El procedimiento de elevación del seno maxilar utilizando hueso autógeno se consideraba la opción estándar de oro para la rehabilitación oral en casos de maxilar atrófico grave. Sin embargo, no siempre es una opción viable, debido a las limitaciones o a la morbilidad causada por técnicas de injerto, lo que justifica la existencia de sustitutos óseos que han sido elaborados y mejorados. En cuanto a la amplia variedad de sustitutos óseos, se hace difícil la mejor elección de biomaterial. El objetivo de este informe es presentar una variedad de sustitutos óseos respetados en la literatura científica actual, usados en la elevación del seno maxilar.
