Determinants of Occlusion
A study of the form and function of the anterior teeth requires a knowledge of the “determinants of occlusion”. The posterior determinant is the ___ ____ of the right and left ___ ____This is a____ determinant and ___ be ___. The anterior determinant is referred to as ____ or ___ ____; this determinant can be ____. The anterior teeth must function in harmony with the rest of the masticatory system. A further important determinant is the ____ ____.
Static Relations of the Anterior Teeth
Two variables contribute to anterior guidance -__ and _____
Normal interarch relationships of the anterior teeth:
____overlap (overbite)
_____ overlap (overjet)
Static Relations of the Anterior Teeth
Two variables contribute to anterior guidance -overbite and overjet
Normal interarch relationships of the anterior teeth:
V.O. -vertical overlap (overbite)
H.O. -horizontal overlap (overjet)
Overbite is the ____ overlap of the ___ __ teeth over the labial surfaces of the ____ ___ teeth in ___ ____. Ideally, the amount of overbite is ______
Overbite is the vertical overlap of the maxillary anterior teeth over the labial surfaces of the mandibular anterior teeth in centric occlusion. Ideally, the amount of overbite is 1.5 -2.0 mm.
Overjet is the ____ overlap of the maxillary anterior teeth to the labial surfaces of the mandibular teeth in centric occlusion. In maximum intercuspation the mandibular anterior teeth should be ____ ___ ___ ___ with the lingual surfaces of the maxillary anterior teeth or in ___ ___ than the posterior teeth. Overbite and overjet also occur in the ___ teeth.
Overjet is the horizontal overlap of the maxillary anterior teeth to the labial surfaces of the mandibular teeth in centric occlusion. In maximum intercuspation the mandibular anterior teeth should be sliQhtlv out of contact with the lingual surfaces of the maxillary anterior teeth or in lighter contact than the posterior teeth. Overbite and overjet also occur in the posterior teeth.
Anterior (Jncisall Guidance
Anterior or incisal guidance is the dynamic relationship of the ____ to ___ ___ teeth ___ ____. As the mandible moves forward from centric occlusion, anterior tooth ___ is made, (if not present in centric occlusion); further forward movement of the mandible then ____the posterior teeth from occlusal contact. This separation of the posterior teeth is called ___ ____. It may also occur during ___ movements of the mandible.
Anterior (Jncisall Guidance
Anterior or incisal guidance is the dynamic relationship of the mandibular to maxillary anterior teeth during function. As the mandible moves forward from centric occlusion, anterior tooth contact is madeCif not present in centric occlusion); further forward movement of the mandible then disengages the posterior teeth from occlusal contact. This separation of the posterior teeth is called posterior disclusion. It may also occur during lateral movements of the mandible.
The contribution of anterior guidance to posterior disclusion is greatest in the ____ area, whereas the contribution of condylar guidance to posterior disclusion is greatest in the ___area.
The contribution of anterior guidance to posterior disclusion is greatest in the premolar area, whereas the contribution of condylar guidance to posterior disclusion is greatest in the molar area.
The greater the overjet, the ___ the cusps must be. The lesser the overjet, the ____ the cusps may be.
The greater the overbite, the ____ the cusps may be. The lesser the overbite, the ___ the cusps must be.
The greater the overjet, the shorter the cusps must be. The lesser the overjet, the longer the cusps may be.
The greater the overbite, the longer the cusps may be. The lesser the overbite, the shorter the cusps must be.
The anterior guidance should be___ ___or slightly ___- than the condylar guidance. Therefore, the steeper the angle of the eminentia. the ___the lingual concavity of the maxillary anterior teeth must be. The shallower the angle of the eminentia. the____he lingual concavity of the maxillary anterior teeth may be.
The anterior guidance should be equal to or slightly greater than the condylar guidance. Therefore, the steeper the angle of the eminentia. the lesser the lingual concavity of the maxillary anterior teeth must be. The shallower the angle of the eminentia. the greater the lingual concavity of the maxillary anterior teeth may be.
The steeper the angle of the eminentia. the ____ the cusps may be. The shallower the angle of the eminentia, the ___ the cusps must be.
The steeper the angle of the eminentia. the longer the cusps may be. The shallower the angle of the eminentia, the shorter the cusps must be.
Forward movement of the mandible is called ____ movement. As the mandible moves forward from centric occiuslon, the mandibular anterior teeth eventually assume an edge-to-edge position with the maxillary anterior teeth. This relation is called the ___ ___ ___
Forward movement of the mandible is called protrusive movement. As the mandible moves forward from centric occiuslon, the mandibular anterior teeth eventually assume an edge-to-edge position with the maxillary anterior teeth. This relation is called the incisal edge position.
During lateral movement of the mandible, the side to which the mandible moves is called the -___ side. The side, which the mandible moves away from, is referred to as the __ or -_–side.
During lateral movement of the mandible, the side to which the mandible moves is called the working side. The side, which the mandible moves away from, is referred to as the non-working or balancing side.
The functional classification of an occlusion during lateral movement is made on the _____ side.
Group function is the relationship when the __and the _____ ____of the posterior teeth on the ____ side contact ___ The functional inclines are the ___ inclines of the maxillary ____ cusps and the ____ inclines of the mandibular ___ cusps.
The functional classification of an occlusion during lateral movement is made on the working side. Group function is the relationship when the cuspids and the functional inclines of the posterior teeth on the working side contact evenly. The functional inclines are the inner inclines of the maxillary buccal cusps and the outer inclines of the mandibular buccal cusps.
Cuspid rise or cuspid protected occlusion is the relationship when the cuspids on the working side are the ___ ___ ____
Cuspid rise or cuspid protected occlusion is the relationship when the cuspids on the working side are the only teeth contacting
A mutually protected occlusion is that relationship when the ____ and the ____ on the working side are the only teeth contacting.
A mutually protected occlusion is that relationship when the cuspids and the incisors on the working side are the only teeth contacting.
These functional relationships of the anterior teeth (in protrusive and lateral movements) contribute substantially to the protection of the ___, ____ and ___ ___
These functional relationships of the anterior teeth (in protrusive and lateral movements) contribute substantially to the protection of the teeth, muscles, and supporting structures.
