Platform Switching
Definiția Platform Switching
Os cortical
Gingie
Os spongios
Platform switching este un concept prin care conexiunea dintre implant si bont este schimbată pe interior (spre centru)
Dimensiuni biologice
Dimensiunia gingiei sănătoase = 3mm
1mm adâncimea sulculară
1mm epiteliu gingival
1mm țesut conjunctiv
Connection troubles
Five sources of interference have been identified in a connection The presence of a joint is a source of tissue disturbance
The presence of a micro gap (precision of the connection),
screwing and unscrewing of the healing/ prosthetic abutments
Implant / prosthetic micro motion
bacterial infiltration
Stresses due to the function occlusion.

Hypothesis & Theory of the SP connection
Gain in soft tissue volume around the implant
Gain in Biologic Width
The PS allows a good seal (ring) around the implant
Greater resistance to bacterial ingress.
Moves the inflammatory zone at the inside connection .
Oriented inflammation flux in a PS connection
lateral stresses are not concentrated at the coronal site
Prevent or significantly reduce any bone loss
