Occlusion is a key factor for implant success in the long run. As occlusal overload is regarded as one of the main causes of peri–implant bone loss and implant prosthesis failure. The occlusal rehabilitation schemes for implant–supported prostheses are derivatives of the occlusal scheme for natural dentition. The implant–protected occlusion (IPO) scheme has been designed to ensure the longevity of both prosthesis and implant. The article reviews the concepts of IPO and their applicability in different clinical scenarios
