Maintaining the integrity of the connection between the prosthetic superstructure and the fixture plays an important role in the success of implant treatment. Implant restorations can be screw retained or cement retained, each having its own advantages and disadvantages. Nowadays, cemented restoration is commonly opted as it has several advantages for use as a fixed implant prosthesis such as passive cast, equal stress distribution, enhanced esthetics, lower cost, and less time-consumting. Despite higher success and survival rates of cement-retained prosthesis due to advanced materials and proven designs, mechanical failures like cementation failures are been reported. This may be due to the compromised retentive form of the abutment or bond failure. Here, a case is documented where the patient reported with frequent dislodgment of cement-retained crown due to compromised height of implant abutment in a deeply placed single-piece implant. |
