An idealized alveolar bone positioned in class I relation axially aligned to the opposing arch is the concept for optimal dental restoration, even if there are frequent discrepancies between the jaws, such as skeletal class III malocclusion with an increase of older patients seeking correction of their jaw deformities. Usually, in such a case, dental implants are inserted after orthognathic treatment as it is difficult to plan the postsurgical occlusion before surgery. Kim et al. gave evidence that implant placement after orthognathic surgery enhances marginal peri-implant bone loss as well as the incidence of peri-implant mucositis and peri-implantitis compared to a nonorthognathic control group. The authors concluded that this deteriorated osseointegration may be due to the regional acceleratory phenomenon (RAP) after the noxious stimulus obtained by the surgical procedure. Here, a shift of osteoclasts and osteoblasts was proposed, leading to an osteopenic effect.3...
