Resumo: UNLABELLED: Different filling materials have been used in an attempt to repair bone loss situations. OBJECTIVE: The present study aimed to examine the effect of a bone matrix in post - extraction remodelling of the alveolar bone, and to perform a histomorphometric analysis of the residual alveolar ridges in Wistar rats. MATERIAL AND METHODS: Both rat first lower molars were extracted and the right alveoli were filled with particles of a bone matrix with mineral components (MO - UNC) (experimental group, EG). The left alveoli were used as a control group (CG). The animals were sacrificed at 0 hr., 15, 30 and 60 days after extraction, and the samples were processed. Histological sections were made at the level of the mesial alveolus of the first lower molar. Repair of the alveoli was histologically evaluated and a histomorphometric study of total alveolar volume (TAV), height of the buccal plate (Bh), height of the lingual plate (Lh) and percentage of osseointegration (OI) of the particles was performed to compare the residual ridges of CG with those of the EG. Statistical analysis of the data was performed. RESULTS: In the cases of the experimental group, newly - formed bone tissue was identified around the MO - UNC particles (osseointegration). Histomorphometric data indicate that, at 60 days post - extraction, TAV was significantly greater for EG when compared with CG (p <0.05) and the percentage of osseointegration of the particles increased as a function of time (57.6

, for EG at 15, 30 y 60 days respectively). CONCLUSIONS: The bone matrix (MO - UNC) evaluated in this study is an osteoconductive material that prevents the collapse of post - extraction alveolar bone.

Título: Alveolar wound healing in rats fed on high sucrose diet / Alveolar wound healing in rats fed on high sucrose diet.
Fonte: Acta odontol. latinoam;26(2):97-103, 2013.
Idioma: es.
Resumo: The potential for bone repair is influenced by various biochemical, biomechanical, hormonal, and pathological mechanisms and factors such as diet and its components, all of which govern the behavior and function of the cells responsible for forming new bone. Several authors suggest that a high sucrose diet could change the calcium balance and bone composition in animals, altering hard tissue mineralization. The mechanism by which it occurs is unclear. Alveolar healing following tooth extraction has certain characteristics making this type of wound unique, in both animals and humans. The general aim of this study was to evaluate and quantify the biological response during alveolar healing following tooth extraction in rats fed on high sucrose diets, by means of osteocyte lacunae histomorphometry, counting empty lacunae and measuring areas of bone quiescence, formation and resorption. Forty-two Wistar rats of both sexes were divided into two groups: an experimental group fed on modified Stephan Harris diet (43

sucrose) and a control group fed on standard balanced diet. The animals were anesthetized and their left and right lower molars extracted. They were killed at 0 hours, 14, 28, 60 and 120 days. Samples were fixed, decalcified in EDTA and embedded in paraffin to prepare sections for optical microscopy which were stained with hematoxylin/eosin. Histomorphometric analysis showed significant differences in the size of osteocyte lacunae between groups at 28 and 60 days, with the experimental group having larger lacunae. There were more empty lacunae in the experimental group at 14 days, and no significant difference in the areas of bone activity. A high sucrose diet could modify the morphology and quality of bone tissue formed in the alveolus following tooth extraction.

Resumo: RESUMEN Introducción: estudios recientes indican que la cresta infracigomática es un sitio favorable para la colocación de mini implantes, sin embargo es importante conocer sus dimensiones anatómicas para colocarlos en una posición segura y lograr buena estabilidad. Objetivo: determinar el área, en diferentes zonas de la cresta infracigomática, que son utilizadas para la colocación de miniimplantes. Materiales y métodos: estudio descriptivo, observacional y transversal de 60 casos, con previo tratamiento de Ortodoncia y que reunieron los criterios de inclusión. Se utilizaron archivos radiográficos y de tomografías con tecnología cone-beam. Se realizó la estadística descriptiva y pruebas ANOVA, t de Student y método de comparación de Tukey para relacionar las variables. Resultados: la zona de mayor área de hueso se encontró a nivel de la cúspide mesiovestibular del segundo molar (30.2+12.1mm2). La clase esqueletal II presentó mayor área (33.6+11.2mm2). Se encontraron diferencias estadísticamente significativas al relacionar las variables área y zona, así como área y clase esqueletal, pero no hubo significancia estadística al relacionar el área con el sexo. Conclusiones. a nivel de la segunda molar superior es la referencia ideal para la colocación de mini implantes, en la cresta infracigomática, ya que esta tiene mayor área. Los casos Clase II presentan también un área mayor. El sexo no fue determinante (AU).

ABSTRACT Introduction: recent studies indicate that the infrazygomatic crest is a favorable site for the placement of miniscrew (mini implante), however it is important to know its anatomical dimensions to place them in a secure position and to obtain good stability. Objective: to determine the area in different sites of the infrazygomatic crest that is used for the placement of mini-implants. Materials and methods: descriptive, observational and cross-sectional study of 60 cases, with previous orthodontic treatment, that fulfilled the inclusion criteria. Radiographic and tomographic files with cone-beam technology were used. Descriptive statistics, ANOVA and t-Student tests, and Tukey's comparison method were used to relate the variables. Results: The zone with the largest area was found at the level of the second molar in the mesiovestibular cusp (30.2 + 12.1 mm2). Skeletal class II showed the largest area (33.6 + 11.2mm2). Statistically significant differences were found when relating the area and site variables as well as area and skeletal class, but there was no statistical significance in relating the area to sex. Conclusions: the level of the upper second molar is the ideal reference for the placement of mini-implants in the infrazygomatic crest since it has a larger area. Class II cases also have a larger area. Sex was not determinant (AU).

SUMMARY Introduction: autogenous and autologous bone grafts are the elective material for replacing bones lost by trauma, congenital or acquired pathologic processes and atrophy. Objective: to characterize patients with atrophic rims needing rehabilitation in oral grafting as an alternative treatment in the Maxilla-Facial Surgery consultation of the University Hospital "Faustino Perez" and the Clinic "III Congreso del PCC", municipality of Matanzas, from September 2014 to July 2016. Materials and Methods: longitudinal prospective study. The universe was 20 patients aged 18 years and older, males and females, who presented the diagnosis of partial lack of teeth and alveolar atrophy. The symptoms and signs characterizing this entity were stated by questioning, physical examination and diagnostic means. Results: alveolar traumas were the predominant cause of dental lost in male patients aged 18-37 years. The most affected zone was the anterior region of the upper maxilla; bone lost in height and width predominated, and a great number of grafts conserved the alveolar crest. Conclusions: the use of biomaterials in the treatment of patients with alveolar atrophy together with bone graft was satisfactory in patients who needed a base support on which to put dental grafts (AU).

Título: Cirugía ósea resectiva / Resective osseous surgery
Fonte: Rev. ADM = ADM;77(5):252-256, sept.-oct. 2020. ilus.
Idioma: es.
Resumo: Una de las causas de la evolución de la periodontitis es la formación de defectos óseos y pérdida de inserción clínica. Una manera de eliminar el defecto intraóseo y su bolsa periodontal es eliminar las paredes de hueso que componen el defecto para colocar el complejo dentogingival en una posición más apical. La cirugía ósea es un procedimiento periodontal resectivo que involucra la modificación del tejido óseo del soporte dental, la cual es una modalidad del tratamiento periodontal quirúrgico que puede utilizarse para eliminar eficazmente los defectos óseos periodontales para estabilizar la inserción periodontal. El objetivo del presente estudio es realizar una revisión de la literatura sobre las consideraciones actuales, técnicas y principios de la cirugía ósea resectiva en el paciente periodontalmente comprometido (AU)

One of the causes of the evolution of periodontitis is the formation of bone defects and loss of clinical attachment, where one way to eliminate the intraosseous defect and its periodontal pocket is to eliminate the bone walls that make up the defect to place the dentogingival complex in a more apical position. Bone surgery is periodontal surgery that involves the modification of the supporting bone tissue of the teeth, which is a modality of surgical treatment that can be used to effectively eliminate periodontal defects and stabilize the periodontal insertion. The aim of the present study is to conduct a literature review about the considerations, techniques and principles of resective bone surgery in the periodontally compromised patient (AU)

Título: Losartan improves alveolar bone dynamics in normotensive rats but not in hypertensive rats
Fonte: J. appl. oral sci;27:e20180574, 2019. graf.
Idioma: en.
Projeto: FAPESP.
Resumo: Abstract Hypertension is one of the main causes of premature death in the world; also, it is associated with several bone alterations. Preclinical studies have demonstrated delayed alveolar bone healing in hypertensive rats. However, losartan has been favorable for consolidation of bone grafts and reduction in active periodontitis. Therefore, losartan is suggested to be effective in bone formation stages, as well as in the synthesis of matrix proteins and mineralization. Objectives: To evaluate the alveolar bone dynamics in hypertensive rats treated with losartan by laser confocal microscopy and histological analysis. Methodology: Thirty-two rats, 16 spontaneously hypertensive rats (SHR) and 16 Wistar albinus rats, treated or not with losartan (30 mg/kg/day) were used. Calcein fluorochrome at 21 days and alizarin red fluorochrome at 49 days were injected in rats (both 20 mg/kg). The animals were submitted to euthanasia 67 days after treatment, and then the right maxilla was removed for laser confocal microscopy analysis and the left maxilla for histological analysis. Results: This study showed a greater calcium marking in normotensive animals treated with losartan in relation to the other groups. Laser confocal microscopy parameters showed higher values of bone volume formed, mineralized surface, active surface of mineralization and bone formation rate in normotensive animals treated with losartan. However, a smaller mineralized surface was observed in all hypertensive animals. Conclusion: Losartan can improve bone mineralization parameters under normal physiological conditions, but the same anabolic effect does not occur under hypertension.

Idioma: en.
Projeto: National Natural Science Foundation of China.
Resumo: Abstract Menopause induces oral bone loss, leading to various oral diseases. Mastication importantly affects bone metabolism in the jawbone. Objective: To analyze the effect of enhanced masticatory force on osteoprotegerin (OPG), receptor activator of nuclear factor kappa B ligand (RANKL), and mechano-growth factor (MGF) in alveolar bone of ovariectomized rats and to study the mechanics mechanism of the alveolar bone of ovariectomized rats response to enhanced masticatory force. Methodology: Thirty Sprague Dawley rats were randomly divided into three groups: sham-operation group (fat around the removed ovary + normal hard diet), model group (ovariectomy + normal hard diet), and experimental group (ovariectomy + high hard diet). It was a 2-month experiment. Enzyme-linked immunosorbent assay (ELISA) detected serum estradiol (E2), osteocalcin (BGP) and alkaline phosphatase (ALP) in rats. Bone histomorphometric indices in the third molar region of maxilla were detected by micro-CT; protein expressions of OPG, RANKL, and MGF in the third molar region of maxilla was detected by Western blot; and gene expression of OPG, RANKL, and MGF in the third molar region of maxilla was detected by Quantitative Real-Time PCR. Results: Comparing with model group, serum E2 in experimental group increased but not significantly, serum BGP and serum ALP in experimental group decreased but not significantly, OPG in experimental group in alveolar bone increased significantly, RANKL in experimental group in alveolar bone decreased significantly, RANKL/OPG ratio in experimental group decreased significantly, MGF in experimental group in alveolar bone increased significantly, bone volume to total volume fraction increased significantly in experimental group, trabecular thickness increased significantly in experimental group, and trabecular separation decreased significantly in experimental group. Conclusion: Enhanced masticatory force affected the expression of OPG, RANKL, and MGF in alveolar bone of ovariectomized rats, improved the quality of jaw bone of ovariectomized rats, and delayed oral bone loss by ovariectomy.

Resumo: Introducción: El tratamiento de la hendidura alveolar, del paciente fisurado, permite un adecuado crecimiento facial. Los injertos óseos han sido el tratamiento ideal. Sin embargo la técnica de distracción osteogénica mediante transporte óseo alveolar intraoral ha demostrado ser muy predecible. Objetivo: Describir los resultados del cierre de la Hendidura alveolar, con la técnica de transporte óseo alveolar intraoral bifocal y trifocal en pacientes labio fisurados. Diseño: Estudio retrospectivo de serie de casos. Materiales y métodos: Fueron tratados 4 pacientes con hendidura alveolar unilateral, manejados con la técnica de transporte óseo alveolar intraoral bifocal y trifocal en el año 2008 al 2009, con un seguimiento hasta el año 2014. Todos los pacientes fueron tratados con un aparato Hyrax® (Dentaurum, Alemania) modificado. Resultados: El promedio de distancia del transporte óseo requerido fue de 9,75mm (rango de 15 mm a 9 mm). Se colocaron 5 implantes dentales rehabilitados con prótesis dental fija. Conclusión: El estudio de los casos clínicos demuestra una predictibilidad elevada así como un rango de éxito alto, en los individuos tratados con esta técnica. Por tal motivo el transporte óseo alveolar intraoral es una alternativa eficaz para el tratamiento de hendiduras alveolares extensas.

Introduction: The management of alveolar cleft patients, allows an adequate facial growth in cleft lip and palate patients. Bone grafts have been the gold standard treatment. However, the technique of osteogenic distraction by intraoral alveolar bone transportation has proven to be highly predictable. Objective: To describe the results of alveolar cleft management with the intraoral bifocal and trifocal alveolar bone transportation technique in cleft palate patients. Design of study: Retrospective case series study. Materials and methods: 4 patients with unilateral alveolar cleft were treated with the bifocal and trifocal intraoral alveolar bone transportation technique from 2008 to 2009. The cases were followed up until 2014. All patients were treated with a modified Hyrax® (Dentaurum, Germany) device. Results: The average distance of bone transportation required was 9.75mm (range from 15mm to 9mm). 5 dental implants with fixed dental prosthesis were placed. Conclusion: Clinical cases study demonstrated a high predictability, as well as a high success rate in individuals treated with this technique. Therefore, intraoral alveolar bone transportation is an effective alternative for the management of extensive alveolar clefts.

Resumo: There is no information about the possible impact in denture retention after the use of common denture adhesives (DAs) when poor denture foundations (PDF) are present. Moreover, there is a lack of information about which current formulation provides greater retention and for how long. Twelve models from edentulous patients with different ridge shape and border height were used and complete dentures were manufactured. Four different formulation brands of DAs were tested after 10 minutes and three, six, nine, and 12 hours of DA application using a universal testing machine. The Fittydent® and Fixodent® adhesives had the highest retention at 12 hours. The PDF group increased on average its retention by 400 %. However, the group presented lower retention compared to the good denture foundation group. In conclusion, DAs significantly increased denture retention. The PDF group were the most benefited with the application of DAs. The Fixodent® paste had the highest retention.

No existe información acerca del posible impacto en la retención de dentaduras después del uso de adhesivos dentales comunes (DAs) cuando existen rebordes alveolares deficientes (PDF). Más aun, existe una falta de información acerca de cuál formula actual provee mayor retención y por cuanto tiempo. Doce modelos de pacientes edentulos con diferentes formas y alturas en sus rebordes alveolares fueron usados, y dentaduras completas les fueron realizadas. Cuatro diferentes fórmulas y marcas de DAs fueron evaluadas después de 10 minutos, tres, seis, nueve y 12 horas de que se aplicó el DA usando una maquina universal de pruebas. Los adhesivos Fittydent® y Fixodent® presentaron la retención más alta a las 12 horas. El grupo con PDF incrementó su retención hasta en un 400 %. Sin embargo, el grupo presentó menor retención cuando se comparó con el grupo que posee adecuados procesos alveolares. Los DAs incrementaron significativamente la retención de las dentaduras. El grupo PDF fue el más beneficiado con la aplicación de DAs. La pasta Fixodent® provee la más alta retención.
