Opis

In the late 1950s and early 1960s the concept of developing balanced articulation for fixed prosthodontics was challenged. Two primary philosophical approaches were suggested. Unilateral balance, later referred to as group function, was advocated by Schuyler (1963) . Stuart (1964) suggested eliminating all posterior tooth contacts in eccentric positions. This occlusal scheme has been described as mutually protected occlusion because the posterior teeth act as vertical stops (closure stoppers) and prevent excessive contact of the anterior teeth in MIP, and the anterior teeth disengage the posterior teeth in eccentric positions to protect the posterior teeth from lateral forces . Another term that has been used to describe this occlusal scheme is anterior disclusion (anterior teeth discluding the posterior teeth in eccentric positions). If the canine alone (without involvement of the incisors) discludes the posterior teeth in lateral eccentric positions, the mutually protected occlusal scheme is described as canine disclusion.
