The temporomandibular joints function in synergy with the dental occlusion within the manducatory system. Orthodontists and surgeons must take into account the condylar position since any problem related to positioning of the condyle could result in occlusal disorders including relapse and the risk of occurrence, decompensation or worsening of temporomandibular dysfunction. We wanted to answer three questions: What is the position of the condyle following orthognathic surgery? What benefit is there in repositioning the condyle? What means are available to check condylar position? Finally, in the light of the answers, we describe an innovative occlusal and condylar positioning device for mandibular osteotomies based on computer-assisted surgical planning techniques. It consists of a three-dimensional, printed guide enabling surgeons to position the condyles as desired. It is accurate, simple, reproducible, independent of operator experience as well as rapid and economical.
