When considering implants, which statement is incorrect?

Progressive loading refers to a method wherein the final prosthesis is gradually introduced to functional loading to allow osseointegration to occur without undue stress on the implant. Immediate loading typically involves placing a provisional restoration immediately after the implant is placed, which can be a form of loading but should be carefully approached to ensure the survival of the implant. The distinction lies in the concept of progressive loading suggesting an incremental and cautious approach rather than immediate heavy loading.

The other statements correctly describe principles relevant to implant dentistry. Engaging at least 5 mm of bone apically is a well-established guideline crucial for ensuring primary stability, which is vital for the success of the implant. Grafting may indeed be warranted if there is excessive space between the platform and the extraction socket, indicating insufficient bone for proper support of the implant. Lastly, flatter incline planes do result in more vertical forces and shorter moment arms, affecting the mechanics of forces acting on the implant. Each of these points illustrates fundamental concepts in implant therapy and the importance of technique in managing the biomechanical environment surrounding the implant placement.
