Posterior interferences
ОглавлениеIf posterior teeth ‘get in the way’ (interfere), this can be detected by immediate separation of the anterior teeth and guidance of the mandible is then transferred to the interfering tooth. It is thought that interferences, usually on the non‐working side (Figure 3.18a) but also on the working side (Figure 3.18b), can be responsible for initiating parafunction. Check for the presence of interferences up to maximum lateral excursions. Patients may parafunction with the mandible in very unlikely and extreme lateral positions, and this may not be clinically evident unless you are meticulous with your examination.
