Abstract

To clarify the effects of clinical factors on the failure (early failure) of osseointegration establishment of titanium implants, we statistically carried out a clinical examination on 373 fixtures of Brånemark implants. Fifteen fixtures (4.0%) failed to establish osseointegration before the fitting of superstructures.<br/> Results are summarized as follows:<br/> 1.Age and sex did not affect early failure.<br/> 2.Although there was no significant difference in the rate of early failure between the maxilla and the mandible, the prognosis of the maxilla, in women, was poorer than that of the mandible. No difference among regions in the maxilla or mandible was detected.<br/> 3.Variations of diameters and kinds of fixtures did not affect early failure.<br/> 4.In the length of fixture, the prognosis of 10 mm or less of the fixtures was poor, and the prognosis of fixtures of 13 mm or less was poorer in the maxilla.<br/> 5.The initial stability of fixtures at installation was deeply relevant to early failure.<br/> 6.The healing period between fixture installation and abutment connection did not affect early failure.<br/> 7.There was no significant difference in the rate of early failure between smokers and non smokers.<br/>
