Jw. Brand et al., LATERAL CEPHALOMETRIC ANALYSIS OF SKELETAL PATTERNS IN PATIENTS WITH AND WITHOUT INTERNAL DERANGEMENT OF THE TEMPOROMANDIBULAR-JOINT, American journal of orthodontics and dentofacial orthopedics, 107(2), 1995, pp. 121-128
Twenty-three female volunteers with normal temporomandibular joints (T
MJ) were compared with 24 female patients with documented TMJ internal
derangements. Magnetic resonance imaging and lateral cephalometric ra
diographs were used to investigate the relationship between TMJ disk d
isplacement and skeletal facial form. Results indicated that the patie
nts with internal derangements have significantly smaller mandibles an
d maxillae. However, these sagittal measurements of jaw length were no
t associated with disproportionate changes in other cephalometric vari
ables. In general, no distinct relationship was found between the morp
hologic features of the face and the internal derangements of the temp
oromandibular joint.
