Denture/prostheses wearers may be able to come to the same position without dentures...but you can't call that "occlusion".
Like I said...I guess I wouldnt know this stuff, but that sounds contradictory to common sense
From Glossary of Prosthodontic Terms:
occlusion \a-kloo#shun\ n (1645) 1: the act or process of closure or of
being closed or shut off 2: the static relationship between the incising
or masticating surfaces of the maxillary or mandibular teeth
or
tooth analoguessee CENTRIC O., COMPONENTS OF O.,

centric relation \se˘n#trı˘k rı˘-la#shun\ 1:
the maxillomandibular
relationship in which the condyles articulate with the thinnest
avascular portion of their respective disks with the complex in the
anterior-superior position against the shapes of the articular eminencies.
This position is independent of tooth contact. This position
is clinically discernible when the mandible is directed
superior and anteriorly. It is restricted to a purely rotary movement
about the transverse horizontal axis (GPT-5) 2: the most
retruded physiologic relation of the mandible to the maxillae to
and from which the individual can make lateral movements. It
is a condition that can exist at various degrees of jaw separation.
It occurs around the terminal hinge axis (GPT-3) 3: the most retruded
relation of the mandible to the maxillae when the condyles
are in the most posterior unstrained position in the glenoid fossae
from which lateral movement can be made at any given degree of
jaw separation (GPT-1) 4: The most posterior relation of the
lower to the upper jaw from which lateral movements can be
made at a given vertical dimension (Boucher) 5: a maxilla to mandible
relationship in which the condyles and disks are thought to
be in the midmost, uppermost position. The position has been
difficult to define anatomically but is determined clinically by
assessing when the jaw can hinge on a fixed terminal axis (up
to 25 mm). It is a clinically determined relationship of the mandible
to the maxilla when the condyle disk assemblies are positioned
in their most superior position in the mandibular fossae
and against the distal slope of the articular eminence (Ash) 6:
the relation of the mandible to the maxillae when the condyles
are in the uppermost and rearmost position in the glenoid fossae.
This position may not be able to be recorded in the presence of
dysfunction of the masticatory system 7: a clinically determined
position of the mandible placing both condyles into their anterior
uppermost position. This can be determined in patients without
pain or derangement in the TMJ (Ramsfjord)
