Angle's Classification is the most widely used system for classifying malocclusion, categorizing bite relationships into three main classes based on how the upper and lower first molars fit together.

🦷 Class I Malocclusion
The upper and lower first molars have a normal relationship. Although the jaws are generally well aligned, crowding, spacing, or tooth rotations may still be present.

🦷 Class II Malocclusion
The lower first molar is positioned further back relative to the upper first molar. In this relationship, the upper teeth and jaw appear more prominent, often resulting in an increased overjet and a convex facial profile.

🦷 Class III Malocclusion
The lower first molar is positioned further forward relative to the upper first molar. The lower jaw and teeth project ahead of the upper jaw, often creating an underbite appearance and a more concave facial profile.

While Angle's classification provides a valuable foundation for evaluating occlusion, a comprehensive diagnosis also requires assessment of skeletal relationships, facial proportions, growth patterns, tooth alignment, and overall function.

Understanding these bite relationships helps clinicians diagnose malocclusion, plan treatment, and improve both oral function and facial harmony.

Post-op Complications of Extraction

🔹 Delayed bleeding
🔹 Reactionary hemorrhage: 24–48 hrs
🔹 Secondary hemorrhage: 7–14 days, usually due to infection

🔹 Pain
🔹 Normal pain peaks at ~12 hrs then improves
🔹 Severe/increasing pain after 48 hrs → think dry socket or infection

🔹 Dry socket (alveolar osteitis)
🔹 2–3 days after extraction
🔹 Severe throbbing pain radiating to ear
🔹 Empty socket, exposed bone, foul odor/taste
🔹 No pus
🔹 Common in mandibular 3rd molars, smokers, OCP users

🔹 Post-op edema
🔹 Peaks at 48–72 hrs
🔹 Resolves in 5–7 days
🔹 Ice first 24 hrs, then warm moist heat

🔹 Hematoma / ecchymosis
🔹 Blood collects in tissues → bruising
🔹 May spread downward by gravity
🔹 Usually resolves in 7–14 days

🔹 Infection
🔹 Fluctuant swelling, pus, fever, lymphadenopathy
🔹 Swelling continues to worsen rather than improve

🔹 Trismus
🔹 Muscle spasm, usually medial pterygoid/masseter
🔹 Caused by surgical trauma, prolonged opening, IAN injection
🔹 Treat with warm compresses, NSAIDs, soft diet, jaw exercises

High-yield pearl
🔹 Dry socket = most classic delayed complication
🔹 Severe pain on day 2–3 + empty socket + foul odor + no pus

Osteomyelitis of Jaw

🔹 Inflammation/infection of bone and marrow
🔹 Mandible > maxilla

Causes / risks
🔹 Usually odontogenic infection or trauma
🔹 Risks: radiation, bisphosphonates/MRONJ, diabetes, HIV, bone disease

Acute
🔹 Severe pain, fever, swelling, lymphadenopathy
🔹 May cause lower lip paresthesia
🔹 Early X-ray may be normal; later ill-defined radiolucency

Chronic
🔹 Swelling, sinus tract, pus, tooth mobility
🔹 Sequestrum = dead bone
🔹 Involucrum = new bone around dead bone
🔹 X-ray: moth-eaten radiolucency with sequestra

Variants
🔹 Garre osteomyelitis: child/young adult, onion-skin
🔹 Condensing osteitis: periapical radiopacity from low-grade inflammation

Treatment
🔹 Acute: antibiotics + drainage/source control
🔹 Chronic: surgical debridement/sequestrectomy + antibiotics
