- Abstract: The progressive bone loss at the neck of the implant is a clinical concern since it affects the maintenance of dental esthetics. The stress concentration, the connection type and the microgap appear to be factors that cause alterations at the marginal bone level. The present study evaluated the influence of insertion depth, prosthetic connection and type of loading on the stress distribution around dental implants, using photoelastic methodology. Three blocks of photoelastic resin for each type of implant connection (external hexagon, external hexagon flattened, internal hexagon and Morse taper) were built. Each block differed in the position of the implant platform in relative to the upper margin of the block: I (2mm below), II (at the same level) and III (2mm above). A 100N force was applied to both a straight and tilted abutments. A multiple linear regression showed the relation between the stress distribution and the insertion depth. For all the implant types, both with straight and tilted abutments, Group I presented the lowest stress concentration around the fixture when compared to group II and III(p<0,05)
