A study of different calcification areas in newly formed bone 8 weeks after insertion of dental implants in rabbit tibias
MetadataShow full item record
In orofacial implantology there are many types of implants for the different systems. Among these is the implant surface type, e.g., a screw type, cylindrical and laminar. Furthermore, the implants are different in their dimensions, their metal composition, their surface condition, such as smooth, grit or layered surfaces and in their methods of application. Two different self-tapping implants, one smooth and the other grit-blasted, are screwed into the bone, and another one with a plasma of titanium coating, which is also in a screw form but with greater spaces between the screw threads are compared. The greatest amount of bone deposition in the bone/implant interface was encountered in the latter one, the smooth surfaced implant being in second place. All of these systems can alter the implant healing process and to demonstrate this, we injected bone markers in the rabbits over different periods of time so as to observe the different areas of bone deposition in the tibias where the implants had been inserted. The bone tracers used were Alizarin, Calcein and Xylenol-orange. The amount of deposition was calculated by using the method of surface morphometry.

Cavidade anoftálmica adquirida: avaliação da influência dos implantes orbitários cônicos ou esféricos sobre as versões do olhar e sobre o posicionamento do supercílio e das pálpebras superiores e inferiores; e percepção dos oftalmologistas oculoplásticos com relação ao manejo do portador de cavidade anoftálmica Bigheti, Carolina Pereira (Universidade Estadual Paulista (Unesp), 2021) [Tese de doutorado]Existem vários aspectos da cavidade anoftálmica a serem melhor estudados. Os movimentos do implante orbitário e da prótese ocular externa (POE) não são semelhantes aos do olho normal e este é um ponto muito importante a ...
