The technique proposed aims at reducing the weight of individualized ample ocular prostheses using acrylic resins as well as simplifying laboratory procedure. For that, prefabricated hollow spheres made of plastic material, were inserted in the sclera. The average weights of the solid conventional sclera (5.30g) and those of the respective prefabricated plastic ones (3.91g) were compared. The weight reduction was significative with a confidence interval of 95% by the Student t test. ln addition, for illustration purpose, the technique was applied to patients in the ward of the Maxillofacial Prostheses Dicipline of the Dentistry School in the Campus of São José dos Campos - UNESP, having each patient received a solid prosthesis and a hollow prefabricated one made of plastic material. It has been concluded that the prostheses material spheres were inserted are lighter than the ones which received solid spheres; furthermore, thr technique is viable for ample anophtalmic cavities and requires few sessions

Teeth that have lost much of their coronal tooth structure need intraradical devices to achieve a desired retention of the restorative material, restoring aesthetics and function to the patient. For this purpose, various types of intracanal posts have been studied, of wich the fiber posts have been highlighted with its increasing use in the dental market. The purpose of this study was to present a clinical case of using fiberglass post. As well as critically analyze the published works and points of controversy described by different authors related to factors such as different protocols cementation, surface treatments pins, fracture toughness and compression, the possibility of microleakage, diameter and length of the pin, and the various materials used in conjunction with the intracanal retainers. Thus, we concluded that fiber posts showed as an excellent alternative for anterior teeth, since have least 2 mm of tooth remaining.
