The radiographs showed fairly good response without any occlusal interference
from the lower anteriors.
The Lucia jig not only eliminates any type of occlusal interference
that may cause mandibular deviation of the centric relation (CR) for maximum habitual intercuspation (MHI) but also reduces the effect of muscular hyperactivity.
To evaluate the influence of guiding tooth geometry on contact forces distribution numerical experiment simulating adjustment of occlusal interference
on the surface of one guiding tooth was performed.
Noise on eating/speaking is because of excessive occlusal vertical dimension, occlusal interference
, loose dentures.
Sixty-eight years of experimental occlusal interference
studies: what have we learned?
Masticatory muscle activity before and after elimination of balancing side occlusal interference
Clinical problems noted with talon cusps, both in the primary and in the permanent dentition, are similar and include: attriation, breast-feeding difficulties, compromised aesthetics, occlusal interference
, cusp fracture, interference with tongue space, irritation of the tongue during speech and mastication, displacement of the affected tooth, misinterpretation of radiographs of talon teeth before eruption, caries susceptibility, periodontal problems and temporomandibular joint pain.
As the extra cusp caused occlusal interference
, we planned for gradual reduction of the cusp in successive visits with fluoride application each time.
5 Also in narrow transverse skeletal problems the upper molars are compensated naturally in a buccal direction and their lingual cusps hang down below the curve of Wilson though there may not be a cross bite situation but this may lead to an occlusal interference
from the palatal cusps of upper molars.
Functional complications include occlusal interference
, trauma to the lip and tongue, speech problems and displacement of teeth.
biological complications including dental caries, coronal or radicular abutment fracture, root canal treatment failure, periapical lesions, peri- odontal problems and mechanical failures including occlusal interference
, no occlusal contact, decemen- tation of the prosthesis, esthetic problems, porcelain and metal fractures.
26 Furthermore, any occlusal interference
was checked prior to bonding the lower premolars.
