“…The mechanical properties utilized in the models are listed in Table 2 . The rods were assumed to be made with the grade 2 Ti specified in ASTM F67 [ 16 , 17 ]. The underlying bone was assumed to be the calvarium [ 18 , 19 ], and the same properties were adopted for the newly formed bone.…”

Subperiosteal bone-bonding devices have been proposed for less invasive treatments in orthodontics. The device is osseointegrated onto a bone surface without fixation screws and is expected to rapidly attain a bone-bonding strength that successfully meets clinical performance. Hence, the device's optimum shape for rapid and strong bone bonding was examined in this study by finite element analyses. First, a stress analysis was performed for a circular rod device with an orthodontic force parallel to the bone surface, and the estimate of the bone-bonding strength based on the bone fracture criterion was verified with the results of an animal experiment. In total, four cross-sectional rod geometries were investigated: circular (Cr), elliptical (El), semicircular (Sc), and rectangular (Rc). By changing the height of the newly formed bone to mimic the progression of new bone formation, the estimation of the bone-bonding strength was repeated for each geometry. The rod with the Rc cross section exhibited the best performance, followed by those with the Sc, El, and Cr cross sections, from the aspects of the rapid acquisition of strength and the strength itself. Thus, the rectangular cross section is the best for rod-like subperiosteal devices for rapid bone bonding.

“…The sarcophagus was placed in a vertical position to facilitate the completion of the missing parts. Some stainless-steel bars (6 mm radius) isolated with Paraloid B-72 (5%wt/v) in acetone were used to support the structure [32]. Before applying the filler, the broken edges were dampened first with water to avoid the rapid absorption of water from the filler.…”

A pottery sarcophagus from Saqqara excavation, Egypt suffered from different deterioration aspects including color change, pitting, and separation of some parts of the body.• Documentation and conservation treatments were performed including cleaning, joining, and completion. • The data obtained improved knowledge about the conservation of pottery and led to a detailed protocol for its treatment.

“…Este mortero fue coloreado en masa, con un añadido del 0,25% de pigmentos inorgánicos (tierras y óxidos de hierro), consiguiendo así el tono más acorde con la piedra Este proceso se centró en el diseño de un nuevo sistema de espigas que se ajustara a los huecos y/o cajas de ensamblaje localizadas en los omóplatos de la figura y en la base de las alas. Durante el proceso, se barajaron diferentes alternativas de espiga, pero finalmente se decidió usar un sistema que fuera reversible, compatible con el soporte pétreo y fiable mecánicamente (Berge et al 2009;Kourkoulis y Pasiou 2009;Rahbar et al 2010;Ting Tan et al 2011;Mas-Barberà y Duréndez 2011;Kourkoulis et al 2012;Michel et al 2012;Righetti et al 2015;Chmielewski y Kruszka 2015;Rosewitz et al 2016;Abdullah y Abdul Kadir 2016). En definitiva, se trataba de plantear una alternativa respecto a los refuerzos convencionales donde se emplean espigas y adhesivos termoestables de un modo permanente.…”

El presente trabajo muestra una parte del complejo tratamiento de restauración llevado a cabo en el ilustre Panteón de la familia Pau (1895), situado en el Cementerio General de Valencia. El panteón está atribuido al arquitecto Gerardo Roig i Gimeno y posee unas medidas de 3,90 x 7,85 x 4,2 m. Concretamente, la figura escultórica del ángel alado objeto de esta intervención está tallada en mármol estatuario de Carrara y, del conjunto de daños identificados, la presencia de grietas en la parte trasera representaba el deterioro más destacado, el cual comprometía su estética y estabilidad estructural. Con el fin de dar solución a los daños, se aplicaron una serie de estrategias centradas en, a) desmontaje de las alas; b) limpieza fisicoquímica; c) consolidación; d) tratamiento del volumen, cosidos, sellados, desarrollo de espigas híbridas piedra-fibra de vidrio y montaje de las alas; e) protección; y, f) plan de mantenimiento. El trabajo presentado pone de relieve la operación desarrollada, con un enfoque mínimamente invasivo, lo que permitió recuperar la estabilidad estructural ante el inminente estado de colapso en el que se hallaba la pieza.
