The skeletal relationship of the patient should then be identified and noted. The facial height of the patient should be considered and it should be noted where there may have been a loss. 2) Muscles  Begin by simply palpating the muscles concerned with the occlusion of the teeth. These muscles include the muscles of mastication and other muscles within the head and neck area, such as the supra-hyoid muscles. It is best to palpate the muscles simultaneously and bilaterally. The temporalis, masseter, medial and lateral pterygoids, geniohyoid, mylohyoid and digastric muscles alongside the trapezius, posterior cervical muscles, occipitalis muscle and the sternocleidomastoid should all be checked for any signs of wasting or tenderness. Temporomandibular dysfunction commonly presents with muscular tenderness, but pain or palpable soreness associated with the muscles can also be linked to parafunctional activity. 3) TMJ  TMJ disorders can be detected through occlusal examination. Ask the patient to open and close whilst placing two fingers over the space of the TMJ. Opening of less than 35mm in the mandible is considered to be restricted and such restriction may be associated with intra-capsular changes within the joint. Following this, ask the patient to move their jaw to the right and following this, to the left. Note any clicking, crepitus, pain or deviation. 4) Maxillary / Mandibular Arch  Assess each arch and identify whether there are any signs of occlusal disharmony, overloading, tooth migration, wear, craze lines, cracking or mobility (not due to periodontal causes). Abfraction, faceting and possible vertical enamel fracture lesions should also be noted if present. 5) Contacts in ICP  Begin by assessing the incisor and molar relationship as described above. Similarly examine the overbite and overjet. An overbite of 3-5mm and an overjet of 2-3mms are considered to be within the range of normal. To look at the ICP, articulating paper should be placed on the occlusal surface and the patient asked to bite together, which will mark their occlusal contacts. It is best to check these whilst the teeth are dry. 6) RCP  The patient may be guided into CR using one of the follow methods;   In some patients it may be difficult to guide the mandible into CR, for example in those with muscle tension, muscle splinting, occlusal disharmony or parafunctional habit.
