In Angle Class I occlusion, the mesiobuccal cusp of the maxillary first molar occludes in the:
Answer: Buccal groove of the mandibular first molar
Angle Class I is defined by the mesiobuccal cusp of the maxillary first molar occluding in the buccal groove of the mandibular first molar.
Centric relation is best described as:
Answer: The position where the condyles are in their most superior-anterior position against the articular eminences
Centric relation is a reproducible, load-bearing jaw position where the condyles and discs are seated in the most superior-anterior position against the articular eminences.
Bennett movement is defined as:
Answer: The bodily lateral shift of the mandible toward the working side during lateral excursion
Bennett movement is the bodily lateral translation of the entire mandible toward the working side that occurs during lateral excursion.
During lateral excursion of the mandible, the non-working (balancing) side condyle moves:
Answer: Downward, forward, and medially
The non-working side condyle orbits downward, forward, and medially along the articular eminence during lateral mandibular excursion.
Canine-protected occlusion (canine guidance) is characterized by:
Answer: The canine discluding all posterior teeth during lateral excursions
In canine guidance, the contacting canines during lateral excursion create disclusion (separation) of all posterior teeth, reducing harmful lateral forces on the posterior dentition.
The Curve of Spee is best described as:
Answer: The anteroposterior curvature through the buccal cusp tips of mandibular teeth from canine to third molar
The Curve of Spee is the anteroposterior curvature formed by connecting the cusp tips of mandibular posterior teeth from the canine through the third molar.
Angle Class II, Division 2 malocclusion is characterized by:
Answer: Distal molar relationship with retroclined maxillary central incisors
Class II Division 2 features a distal (Class II) molar relationship combined with lingually inclined (retroclined) maxillary central incisors, often with a deep overbite.
