English to Italian Medical Medical: Dentistry Odontoiatria neuromuscolare

Qual è il soggetto di questa frase?

" This means that there are no noxious contacts received by the periodontal ligaments or the muscular proprioceptors that must be avoided by the muscles (accommodation) ** but rather allow “free” entry ** into myocentric occlusion."

Ecco il contesto:

The second premise is that occlusion is important in
neuromuscular dentistry as a resetting mechanism of the
trigeminal nervous system’s control of the stomatognathic
muscles. Myocentric occlusion is ideally a position in which the
muscles move the mandible from a non-torqued rest position
into full occlusion with minimal muscle accommodation and no
interferences of occlusal contacts until full closure is attained
thus eliminating all torque during closure. This means that
there are no noxious contacts received by the periodontal
ligaments or the muscular proprioceptors that must be avoided by the muscles (accommodation) ** but rather allow “free” entry ** into myocentric occlusion. The jaw muscles will return to rest
position after closure with the muscles maintaining their healthy low tonicity. Relaxed healthy musculature is the gold standard of neuromuscular dentistry.
