Multi-modular implant consists of two modules: lower module - is afull- edged dental implant that has an inner hex and an inner thread for a screw. Upper module (Pre x)– is a cylindrical titanium module with internal and external hex. Both modules are hermeticallyattached to each other, if necessary it’s possible to disconnect modules using a special driver.Modular implant system:1. Depending on clinical scenario it allows for substitution of upper module (Pre x) of the multi-modular implant to any other kind (cylindrical, cone-shaped, angular) during surgical stage of implantplacement.2. Allows to disconnect upper module (Pre x) in case of bone resorption around the implant withoutthe need to remove osseointegrated lower module of the implant and to restore it using all thestandard parts.3. In case of bone resorption it allows to replace upper module (Pre x) and to perform guided boneregeneration. There is no need to replace prosthetic system.
