Introduction: Amalgam, which can be applied with or without dowel, is one of the commonly used restorative materials for core restoration in pulpless teeth. The current study aimed to compare the shear strength of amalgam cores with and without dowel. Methods: A total number of 20 recently extracted mandibular premolars were assigned to two groups of 10 equal s...

Guided implant surgery is not completely accurate when using computer-designed stereolithographic surgical guides. Complications are frequently reported when combining computer-guided flapless surgery with an immediately loaded prefabricated prosthesis. Achieving passive fit of a prefabricated prosthesis on the inserted implants the same day of the surgery can be difficult. The aim of this repo...

To evaluate the seismic performance of pre-cast concrete shear wall with vertical reinforcements spliced by two different grout ways, quasi-static tests of two concrete shear walls holed by prefabricated corrugated pipe and one concrete shear wall holed by drawing out the pipe were tested. The test results showed that the wall holed by prefabricated corrugated pipe was basically the same as the...

The construction industry has acknowledged that its current working practices are in need of substantial improvements in quality and efficiency and has identified that computer modeling techniques and the use of prefabricated components can help reduce times, costs, and minimise defects and problems of on-site construction. This paper describes a virtual environment to support the construction ...

Décembre 2000, Vol. 66, No 11 613 There is no consensus on the best procedure for restoring endodontically treated teeth. However, retrospective studies1-6 do identify factors that affect the success rate. Tooth location in the arch,1-3 type of occlusion,2 amount of remaining dentin3 and type of abutment1 affect the selection of a restorative approach that will produce a favourable outcome. Yet...

BACKGROUND We compared the pre-operative 3D-surgical plan with the surgical outcome of complex two-stage secondary reconstruction of maxillofacial defects using inserted implants in the prefabricated fibula graft. METHODS Eleven reconstructions of maxillofacial defects with prefabricated fibulas were performed using a 3D virtual planning. Accuracy of placement of the fibula grafts and dental ...

the successful management in construction costing of wood dry kilns is an advantageous approach which brings us not only the assurance in service profitability but also gives rise customer’s satisfaction. the construction costing of two types of wood dry kilns, namely, prefabricated aluminum-and masonry kilns with normal operation temperature was studied. for this purpose, the construction, dep...

The relative merit of customised versus prefabricated foot orthoses continues to be the subject of passionate debate among foot health professionals. Although there is currently insufficient evidence to reach definitive conclusions, a growing body of research literature suggests that prefabricated foot orthoses may produce equivalent clinical outcomes to customised foot orthoses for some condit...
