CONCLUSION
The reverse-taper lock is a narrow implant placed in areas that require bone grafting, such as veneer grafts, without actually conducting bone grafting. The implant body of this system is designed to prevent bone resorption by preventing the effects of microgaps and microleakage. The superstructure can be mounted by friction force without screws or cement. In the event of peri-implantitis, the area above the implant body infected with biofilm can be removed, allowing the attachment of a new abutment and superstructure to the remaining part.
