A macrointerlock is a fixation method which mechanically interlocks the bone and the dental implant. This can include the interlocking connections between abutments and implants. Macrointerlocks can also be used to build up fragile teeth before an implant is placed. Following some dental procedures, the canal of the affected tooth can be left hollow which weakens the strength of the tooth and reduces its ability to support an implant. Prior to implant fixation, a macro-lock post may be used to aid in the reconstruction and build-up of such a canal. Without the use of such posts, the tooth may be too fragile or unstable to allow for an implant. Macro lockers can help strengthen the tooth while also increasing the surface area needed for the implant. Macrointerlocks may also provide stability and longevity to the implant as well as to the bone-to-implant interlock.
