Target concept: Mandibular Morphology and Structure

Video generation prompt: A set of adult mandibular specimens is placed on the table for observation of their overall morphology, sites of tooth attachment, and major bony landmarks.

Evaluation guide:
(i) Target concept: Visual verification of normative adult mandibular gross anatomy through comparative observation of multiple dry specimens.
Minimum mechanism: Specimens must be osteologically intact, unaltered dry human mandibles of adult origin; table must provide stable, neutral spatial reference; lighting must enable simultaneous visualization of external bony topography without occlusion or glare.
(ii)Storyline: Frame 1–3: Static wide shot establishing table surface and side-by-side placement of ≥3 mandibles in anatomical position. Frame 4–7: Slight camera dwell (no motion) ensuring all key landmarks (alveolar ridge, angle, mental foramen, condyle, coronoid) remain continuously visible and spatially resolvable across specimens. Frame 8–10: Final stable composition confirming consistent orientation, absence of obstruction, and unbroken visual access to all designated features; no transition, zoom, or repositioning occurs.

Manual:
Experimental Procedure
1. Place three adult dry mandibular specimens side-by-side on a flat, neutral table surface in standard anatomical position (inferior view, rami upright).
2. Orient each specimen to simultaneously expose alveolar ridge, mandibular angle, mental foramen, condylar head, and coronoid process.
Observation of Experimental Phenomena
- Multiple specimens show consistent bony architecture: distinct body, two rami, U-shaped dental arch, and five key landmarks visible per specimen.
- Alveolar ridge displays continuous, scalloped topography aligned with tooth sockets.
- Landmarks maintain fixed spatial relationships: mental foramen on body surface, condylar head superior to mandibular notch, coronoid process anterior to condyle.
Summary of Experimental Principles
Mandibular morphology reflects functional adaptation: body supports teeth via alveolar ridge; rami enable muscle attachment and TMJ articulation; landmarks serve as surgical, radiographic, and anthropometric reference points.

Prompt Grounding rubric:
level_1: No adult mandibular specimens visible; or specimens present but not placed on a table surface; or table absent; or more than one distinct anatomical structure (e.g., skull, maxilla, vertebrae) dominates the frame.
level_2: Adult mandibular specimens are present and placed on a surface, but the surface is not a flat, neutral table (e.g., tray, shelf, hand-held); or only one specimen visible when multiple are required; or specimens obscured by labels, gloves, or tools; or tooth attachment sites or bony landmarks are not visually accessible due to orientation (e.g., all specimens shown in occlusal view only, hiding ramus/coronal landmarks).
level_3: Multiple adult mandibular specimens are placed side-by-side on a flat, neutral table surface; all specimens are fully visible in standard anatomical position (inferior view or slightly oblique inferior-superior angle showing both body and rami); tooth attachment sites (alveolar ridge) and at least two major bony landmarks (e.g., mandibular angle + mental foramen OR condylar head + coronoid process) are simultaneously discernible across the set.
level_4: All conditions for score 3 satisfied, AND all specimens are oriented consistently (same rotational alignment relative to table plane); AND no non-mandibular objects (e.g., calipers, teeth models, jaw replicas) appear in the scene; AND table surface is uniform, matte, and uncluttered (no writing, stains, or extraneous shadows).
level_5: All conditions for score 4 satisfied, AND every specimen clearly displays three or more major bony landmarks (e.g., mandibular angle, mental foramen, condylar head, coronoid process, mandibular notch) with full structural integrity (no cropping, occlusion, or deformation); AND alveolar ridges are uniformly visible along the entire dental arch of each specimen; AND spatial arrangement shows explicit side-by-side comparison (no overlapping, stacking, or depth-layering that hides any specimen’s key features).

Scientific and Causal Correctness rubric:
level_1: Specimens exhibit non-biological morphology (e.g., cartoonish proportions, metallic texture, symmetrical left/right duplication without asymmetry, fused rami, absence of mandibular foramen); or tooth attachment sites appear as smooth surfaces without alveolar ridge topography; or bony landmarks are anatomically impossible (e.g., mental foramen located on ramus, condyle smaller than coronoid).
level_2: Specimens show gross anatomical errors: missing ramus, absent mandibular angle, no distinction between body and ramus, or alveolar ridge completely flat/untextured; or at least one landmark is mislocated (e.g., mental foramen on inferior border instead of body, condyle positioned anterior to coronoid); or specimens display pathological distortion (e.g., severe macrognathia/micrognathia inconsistent with normal adult variation).
level_3: All specimens display canonical adult mandibular morphology: clear separation of body and two rami; presence of mandibular angle, condylar head, coronoid process, mandibular notch, mental foramen, and alveolar ridge; alveolar ridge shows continuous, scalloped topography corresponding to tooth positions; no landmark is anatomically inverted, duplicated, or transposed.
level_4: All conditions for score 3 satisfied, AND bilateral symmetry is natural (not perfect mirror symmetry; minor left-right differences in angle prominence or foramen position present); AND alveolar ridge topography matches expected dental arch curvature (parabolic, not linear or U-shaped); AND condylar heads and coronoid processes are correctly proportioned relative to ramus height (neither disproportionately enlarged nor atrophied).
level_5: All conditions for score 4 satisfied, AND every specimen shows accurate spatial relationships among landmarks: mental foramen located midway between superior/inferior borders of body and aligned vertically with second premolar; mandibular notch positioned superior to angle and inferior to condyle; condylar head articulates with temporal bone in correct anteroposterior orientation (no posterior tilt or medial displacement); no landmark appears artificially emphasized, smoothed, or digitally enhanced beyond natural bone texture.

Spatiotemporal Consistency rubric:
level_1: Specimens teleport between frames (e.g., change position/orientation discontinuously); or table surface exhibits abrupt lighting shifts, warping, or perspective breaks (e.g., table edge bends unnaturally); or specimens flicker, vanish, or morph between frames; or background changes identity (e.g., lab → outdoors).
level_2: Minor spatial discontinuities: one specimen rotates >30° without visible motion path; or table surface shows inconsistent shadow direction across frames; or two specimens shift relative to each other without correlated motion; or lighting intensity changes abruptly (e.g., bright → dim in single frame).
level_3: All specimens remain fixed in position and orientation throughout; table surface maintains consistent planar geometry and uniform matte texture; lighting remains stable in direction, intensity, and color temperature; no object enters/exits frame; no structural warping or stretching of mandibular contours across frames.
level_4: All conditions for score 3 satisfied, AND camera viewpoint remains absolutely fixed (no pan, tilt, zoom, or parallax shift); AND all specimens maintain identical relative spatial positions (no drifting apart/merging); AND cast shadows from specimens align consistently with light source and do not invert, disappear, or distort across frames.
level_5: All conditions for score 4 satisfied, AND inter-specimen spacing remains constant and visually uniform (no perceived compression/expansion in depth); AND no motion blur obscures anatomical details; AND no frame exhibits lens distortion (e.g., barrel/pincushion) affecting mandibular contour fidelity; AND specular highlights (if present) remain static and physically plausible (e.g., no moving hotspots on bone surface).
