17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
Purpose of clinical photographs in orthodontics
- Aiding in meticulous examination and treatment planning
- Assessment of soft tissue patterns
- Lip morphology
- Smile aesthetics
- Degree of incisal show
Additionally, they are instrumental in research, publication, teaching, and lecturing presentations
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
How clinical photographs contribute to treatment planning
- Provide valuable insights into patient’s soft tissue patterns
- Lip morphology
- Smile aesthetics from different angles
- Enable formulation comprehensive treatment plans
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
Checklist when capturing clinical photographs
- Proper orientation of patient’s head in all three planes
- Teeth in centric occlusion
- Relaxed lips
- Glasses removed
- Camera parallel to frontal plane of head at eye level
- Lateral photographs=>camera parallel to median plane
- Patient’s head=>oriented to Frankfurt plane w/ eyes open and ears exposed
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
Recommended formats for clinical photographs
- 9x13cm=>, allowing for tracing of reference lines
- One frontal view and one lateral view facing to right
- Supplemental photos=>
- Frontal views w/ patient smiling
- 3/4 profile view
- Lateral view facing to left
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
Key components of extraoral clinical photographs
- Frontal views w/ relaxed lips and smiling
- Lateral (profile) views preferably from right w/ relaxed lips and smiling
- 45° profile view while smiling w/ relaxed lips
These photographs provide insights into incisor angulation, midface deformities, gonial angle prominence, mandibular border definition, and lip relationships
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
Types of intraoral photographs recommended for analysis
- Frontal views in occlusion
- Right and left buccal views in occlusion
- Upper and lower occlusal views using mirrors
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
key landmarks used in profile view analysis
- Trichion (Tr)
- Nasion (N)
- Stomion (Sto)
- Subnasale (Sn)
- Orbitale (O)
- Porion (P)
- Labrale superius (Ls)
- Labrale inferius (Li)
- Submentale (Sm)
- Pogonion (Pog)
- Gnathion (Gn)
- Menton (Me).
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
Planes and lines utilized in profile view analysis
- Frankfurt Horizontal
- Dreyfuss perpendicular
- Simon perpendicular
- Mouth tangent T
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
Primary purpose of frontal view analysis in orthodontics
- Evaluate disproportions and asymmetry=>
- Midsagittal and horizontal planes of face
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
How reference lines applied in frontal view analysis, and what they allow for
- Vertical and horizontal reference lines applied to segment face=>
- Assess symmetry and proportions
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
Landmarks and lines utilized in frontal view analysis
- Include those that define=>facial width
- Height
- Proportions such as glabella
- Tip of the nose
- Subnasale, stomion
- Labrale superius and inferius
- Submentale, pogonion, gnathion
- Menton
- Upper lip length, lower lip length, and the Frankfurt horizontal
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
How face shape determined in frontal view analysis, and facial indices used
- Facial indices=>Facial index and index of facial morphology (IFM)
- Facial index=>compares facial height to facial width
- IFM=>evaluates ratio of specific facial distances to facial width
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
Different types of faces characterized by facial indices, and how they classified
- Very wide (hypereuriprosopic)
- Wide (euriprosopic)
- Average (mesoprosopic)
- Narrow(leptoprosopic)
- Very narrow (leptoprosopic) types
- Each with specific index value ranges
17. Analysis Of Diagnostic Records - Frontal And Profile Photo Pictures
Significance of the IFM in assessing face morphology, and how different values interpreted
- Considers ratio of specific facial distances to facial width
- Different values of IFM indicate varying face shapes
- Values > 104 = narrow face
- Values between 93 and 103 = average face
- Values < 93 = wide face
