Abstract: Objective: Evaluate the effectiveness of image diagnosis methods used in the vertical location of sites elect to insert mini-implants. Methods: The sample was composed of four patients, in which 32 inter-radicular sites were established in the subsequent area, for setting up mini-implants. These sites were represented by holes filled out with guta-percha in acetate moulder (PCg - contact point of dental crowns in the acetate moulder; PIg - point of insertion of the mini-implant in the acetate moulder). Periapical X-rays, interproximal and computerized tomographies of cone-beam, with the moulders positioned in mouth, were performed and the following points were taken into consideration: PC - radiodense image of the PCg point; PI - radiodense image of the PIg point; PCx - contact point among the determined dental crowns on the X-ray. Vertical measures used: gold-pattern from PCg to PIg; measure 1 - from PC to PI; and measure 2 - from PCx to PI. The measures were compared through descriptive analysis and test t of Student. Results: For the measure 1, differences statistically significant were observed (4.1%), in relation to the gold-pattern, 25% and 100% of the appraised measures in the computerized tomographies, interproximal and periapical X-rays, respectively. For the measure 2, differences statistically significant were observed in relation to the gold-pattern (4.1%), 56.2% and 100% of the appraised measures in the computerized tomographies, interproximal and periapical X-rays, respectively Conclusions: The cone-beam computerized tomography was the most precise exam in the evaluation of the vertical position of the elect sites to install mini-implants; the interproximal X-ray can, with reservation, be also used; the periapical X-ray presented unsatisfactory results, being contraindicated for this purpose.
