Purpose: High level of successful maintenance of implants located in anterior part of mandible popularizes economical solutions of implant-retained soft tissue supported dentures including those using narrow mini-implants with small diameter - of 1.8-2.2 mm. Design/methodology/approach: FEM modeling analyses were used to determine distribution of mastication loads between mucous foundation and bone tissue surrounding mini-implants that have 1.8 mm diameter. Examined were two types of commercial solitary denture attachments, described as biomechanically compatible due to their rotational movements freedom or due to the additional pivoting mobility. Findings: In case of both types of attachments the most dangerous lateral implants loadings significantly exceed half of oblique mastication loads value. In mini-implants and bone tissue lateral forces generate a high level of stresses. Research limitations/implications: Analyses were carried out with assumed linear characteristics of materials. Denture-to-soft foundation, as well as implant-to-bone complete adherence was assumed. Practical implications: While using mini-implants it is crucial to carefully evaluate the condition of bone foundation, due to the risk of quick development of atrophic processes in case of insufficient bone parameters. In case of mini-implants very important is very high strength value level and surface quality, due to the fact that in case of diameter of 1.8mm there might occur local yielding and propagation of fatigue cracks. Originality/value: Commercial types of attachments do not deserve the name of mechanically biocompatible, as they do not allow for such significant reduction of overloading effects, as the non-commercial silicone attachments.
