Introduction: M.I.D. (mini dental implants) Atlas endosseous implants are single-phase titanium alloy Grade 5 with variable diameter (1,8-2,2-2,4 mm), so that they can be used even in severe bone atrophies. The entry is performed in the interforaminale area with flapless tecnique.The main indication is the stabilization of lower overdentures, very unstable due to various factors such us movements of the tongue and transverse and vertical bone atrophy in the presence of D1 or D2 bone density. M.I.D. for overdenture can be of two types: mini implants with metal ring with a Teflon cap to be fixed in the prosthesis and mini-implants with a ball held in a soft silicone (Tuf-Link) positioned in the undercut run directly in removable dentures (Atlas, Dentatus).
Case report: Male patient, aged 56, carrier of lower total dentures has a severe mandibular bone atrophy with excessive instability of the prosthetis. After careful clinical and radiographic assessment, we proceeded to the insertion of Atlas 4 MID 2.4 mm in diameter with flapless technique. The excellent primary stability has allowed the immediate loading of implants by applying the silicone retentive "Tuf-Link " in removal denture. Control at 12 months shows the stability of the prosthesis, the successful osteintegration and the integrity of implants due to the careful management of occlusal loads.
Conclusions: Implant System Atlas Implant System has proven to be a microinvasive, atraumatic, reliable and highly predictabl
