Q. Describe IMZ Implant System?
Then came the IMZ Implant System (Interpore IMZ) in 1974. The major difference between the IMZ System and all other relevant implant systems is that an elastic compensating component is inserted between the osseointegrated implant and the prosthetic superstructure. The IMZ implant consisted of two parts: the implant body and the intra-mobile connector (IMC). The latter consisted of the titanium and the intramobile element. The elastic intramobile element was intended to assume the role of periodontal ligament of the natural tooth and provide shock absorption as well as force distribution in order to prevent exceeding the adaptive tissue tolerance when chewing forces are applied. The implant was a cylinder with a half spherical apex; the rounded shape was intended to avoid stress peaks and overloading of the osseous bed in the apical region. Perforations through the base of the implant permitted the ingrowth of bone in the apical region.
