Is Centric Relation Always the Position of Choice for TMDs? Case Report of How TMD and Airway Dimension May Be Associated.

Academic Article


  • Centric occlusion (CO) and centric relation (CR) have been controversial topics in dentistry for almost 100 years. The concept of CR emerged due to the search for a reproducible mandibular position that would enable the prosthodontic rehabilitation of patients needing denture treatment. The following case study is unique because of 2 questions. Which mandibular treatment splint position (CR or CO) was appropriate for the initial and eventual final treatment of this patient for her temporomandibular disorder/myofascial pain and dysfunction? Also, how might the mandibular position of CR and CO affect the size and shape of the airway? The airway's size and shape is important as it relates to sleep-disordered breathing and potentially leading to obstructive sleep apnea later in life. The authors believe this is the first case report describing how mandibular position of CR and CO may affect not only TMJ position but also the airway shape and size in three dimensions.
