Passive fit of the implant crown




Ideal occlusal form

Flexibility of fixture placement

DanSoDental Lab with Cement Retained Implant

DanSo Dental Lab. recommends that most implant restorations should have some form of retrievability. This is achieved by the use of temporary cement, access holes or screw retained crowns.Most clinical temporary cements are acceptable.
Cemented prostheses on fixed abutments are a simple treatment concept. The abutment will be individualized in the laboratory. No heat from grinding will affect the gingiva, the implant will not be damaged by grinding, and no metal dust will be sprayed in the gingival tissues. The individualized abutments have to be transferred in a resin splint. If abutments and framework are seated passively and exactly, the prostheses can be completed.
Implant prostheses should be temporarily cemented if alterations are foreseeable. If the implants have osseointegrated successfully and no soft tissue management will be necessary, the restorations can be fixed permanently.
In some cases we combine fixed abutments and screwed abutments in one implant superstructure. The indications are bridges with only little friction and superstructures on several implants when there are reasons to have the prosthesis removable. In this combination, cementation on the fixed abutments must always be temporary.
Cement-retained restorations avoid the obvious disadvantages of screwed implant prostheses. Successful surgical protocols, reliable implant systems, and execution of biomechanical prosthodontics are the conditions for cementation of implant restorations.
Passive seated cemented restorations do not transfer stress on the implants. There is no effect to the gingiva due to corrosion and/or bacterial development in the crevice. High esthetics are achieved by the use of ceramics and galvana-gold frameworks on fixed abutments. Cost efficiency is a welcome side effect

Cement Retained Implant Advantages

Independent on implant orientation / angulation

An abutment is attached to the implant with a screw. A crown is then cemented onto the abutment.

Enhanced esthetics

A cemented crown has no screw access hole and looks like a natural tooth.
