MARTINEZ GONZALEZ, José María et al. Clinical and radiographic behaviour of 290 dental implants with a surface treated with hydrofluoric acid  and passivated with hydrofluoric and nitric acid: early loading results after 2 years. Med. oral patol. oral cir. bucal (Ed.impr.) [online]. 2005, vol.10, n.4, pp.355-361. ISSN 1698-4447.

Objective: This work presents the results of clinical and radiological behaviour, for 2 years, of 290 implants treated with a first etching with HF and a second etching with HF and HNO3 acids and that were loaded 8 weeks after insertion. Experimental design: It is a prospective study on 290 implants placed in 56 patients with an age range from 28 to 81. The selection was previously made through radiological study with panoramic and tomographic radiographs, followed by the implantological treatment with prosthetic loading and clinical (15 days, 1, 3 , 6, 12, 18 and 24 months) and radiological control (12 and 24 months). Results: During the healing period, 11 implants failed, resulting in a CSR of 96.21%. After prostheses placement at 2 months, 4 implants were retired, successfully remaining 275 implants. Conclusions: The following and favourable results after the prosthetic loading of 179 implants (CSR of 98.56%), attest that early loading may and must be applied, after rigorous planning and case selection.
