Abstract |
: |
The recording of jaw relations in the treatment of
edentulous patients aims at facilitating the adaptation of
the complete dentures to the masticatory system to give
an optimal and comfortable function. To achieve this
goal, the recording must include an appropriate vertical
dimension of occlusion and stable occlusal contacts in
harmony with the TMJ, masticatory muscle functions and
finally with the relationship between the prosthesis and
the oral and the facial musculature.1,2
Innumerable patients can not wear complete dentures
then have continual difficulty in using them, principally
because accurate vertical dimension of the natural
dentition was not reproduced in complete dentures.
Vertical dimension is in reality the most fundamental
consideration in treatment planning. It is related, to the
masticatory, respiratory and deglutitive function.3,4
Occasionally a patient with complete dentures will
display an obviously reduced vertical dimension of
occlusion. When faced with the challenge of making new
dentures in this situation, it is desirable for the dentist
to reestablish the patient's optimum vertical dimension
of occlusion.5 As if the vertical dimension was too great
the patient will complain of soreness of the residual
ridges, tightness of the facial muscles and clicking of the
dentures during speech, also it induces an increased rate
of resorption of the remaining alveolar bone.4,6,7
The necessity of a correct vertical dimension for the
health of the temperomandibular joint is considered
as basic knowledge. The profession still remembers
"Costen's syndrome" and ear and facial pains caused by
closed vertical dimensions.8
Facial height, or vertical dimension, consists of two
components: (1) the more objective VDO, which is
the shortest measure of facial height involving centric
occlusion contacts; and (2) a more subjective measure of
facial height termed rest position without tooth contact.9
Neuromuscular posturing of the mandible establishes
this slightly greater measure of facial proportion |
