OLATE, S.; DUQUE DE MIRANDA CHAVES NETTO, H.  e  ALBERGARIA-BARBOSA, J.R. de. Microstructural analysis of five commercially pure titanium implant systems. Avances en Periodoncia [online]. 2010, vol.22, n.1, pp.37-43. ISSN 2340-3209.

Nowadays there is a great number of manufacturers and types of implants which has led to several techniques in their production, not always associated with better quality. The aim of this research was identify and typify five commercially pure titanium implant systems. A double-blind, descriptive trial was used with the selection of 15 samples from 5 different manufacturers. Each implant was removed from its package keeping its original characteristics. Five implant groups of 3 elements each were formed and named A, B, C, D, and E. The analyses included metallography, scanning electron microscopy with a microanalysis system (SEM-EDS) and, finally, an image analyzer. Implamed^® and Master Screw^® showed smaller grain sizes. In micrographies, they all showed peaks of titanium, carbon, and oxygen. Implamed^® showed iron, sodium, magnesium, silicon, potassium, and calcium inclusions. All samples showed good finishing. Variations observed would not be enough to interfere with osseointegration but metal inclusions should be studied in greater detail in order to assess its effects in the long run.
