A: Losing teeth can affect:
😞 Confidence
💔 Self-worth
💑 Relationships
🧑🎨 Personality
🫣 Appearance
🫢 Socialising
👔 Career
🎨 Hobbies
🦴 What happens to the alveolar bone after tooth loss?
Significant alveolar atrophy in first year after extraction 😣
Can lose 5–10 mm of crest height in the first year 📉
After year 1: 0.2–0.3 mm annual ridge loss
Makes denture construction harder 😬
Bone loss extent is unpredictable 😕
👩⚕️ What should you focus on when first assessing a patient for dentures?
A:
Develop rapport 🤝
Show empathy for their problems 💗
Don’t make false promises ❌
Use their words to describe complaints, ask for clarity 🤔
Understand how it’s affecting function/aesthetics 🗣️🍽️
Assess problems with existing dentures if present 🦷
Q: 🗓️ What do you ask about in the patient’s history?
🩺 HPC
How long it’s been an issue ⌛
Better/worse? ⬆️⬇️
Expectations? Realistic? 🤞
Average partial denture lifespan: 8 years ⌛🦷
🦷 PDH
Why & when teeth were lost ❓
Previous denture experience (acrylic/metal?) 🤔
What went wrong? 😕
🏡 SH
Ability to attend appointments 🚗
Carers? Needs support? 👥
Hobbies affected by teeth 🎸🎨
⚕️ MH
Muscle/dexterity issues 🦾
Dry mouth (meds/conditions) 💊
Mental health concerns 🧠
🧑🔬 What’s involved in the extra-oral exam?
A:
Facial form/shape 👤
Symmetry ⚖️
Lip support 👄
Incisal display 😁
Angular cheilitis (denture-related) 🤕
👅 What should be assessed intra-orally without dentures?
Saliva flow 💧
Ridges & undercuts 🏔️
Pathology (red/white patches, lumps) 🩸
Mucosa condition 👄
Oral hygiene 🪥
Abutment teeth condition 🦷
🦷 What should be assessed intra-orally with dentures in?
Denture retention & stability 👌
Abutment teeth & clasp condition 🔩
Signs of wear and hygiene 🧼
Fit, overextension/underextension 🤏
🧪 What signs of pathology should you be aware of?
Ulcers 🩹
Red/white patches ⚪🔴
Lumps/growths ⚠️
Cleft palate – may cause nasal regurgitation 😷
❓ What questions guide the decision to replace missing teeth?
What does the patient want? 🤔
How are they affected (speech, function, aesthetics)? 🗣️🍔🪞
Will not replacing teeth affect remaining dentition? 🦷
Must discuss pros & cons of replacement ⚖️
🦷 What is the shortened dental arch (SDA) theory?
Most patients manage well with ≥ 4 occluding units
Premolars = 1 unit, molars = 2 units
Ideally, 6 occluding units, symmetrically ⚖️
✅ What are the benefits of dentures?
Restore aesthetics 😁
Improve function 🦷🍽️
Aid speech 🗣️
Prevent unwanted tooth movement 📉
Can replace soft tissues too 🧽
Quick to make in urgent situations ⏱️
Help with full-mouth extractions (transition dentures) 🔁
❌ What are the disadvantages of dentures?
Bulky/uncomfortable 😕
Soft tissue coverage = plaque trap 🦠
Saliva can’t cleanse tissue under denture = Candida risk 🍄
Some patients dislike them 😬
🧰 What are the main prosthetic options?
Do nothing 🚫
Partial denture (acrylic or chrome) 🦷
Resin-retained bridge 🦾
Conventional bridge 🌉
Implant 🦷🔩
🧊 What are the indications for acrylic dentures?
Cheap & easy 💷
Quick denture needed 🏃♀️
Transitional (temporary) while waiting for sockets to heal 🕒
Can be added to if more teeth are lost ➕🦷
🔩 What are the indications for chrome (CoCr) dentures?
More retention & support 🛠️
Minimal gingival coverage 🩸
Only if abutment teeth are healthy ✅
If metal showing isn’t a concern 🤷♀️
📅 What factors influence denture treatment planning?
Oral health 🌟
Timeline 🕓
Other planned treatment (e.g., crowns) 🦷👑
Oral hygiene & motivation 🪥
🚨 When is a patient NOT ready for dentures?
Visible plaque 😬
Active caries 🦷
Retained roots 🌱
Gingival inflammation 🔥
✅ When IS a patient ready for dentures?
Improved OH 🪥
Caries treated 🛠️
Roots extracted 🌿
Inflammation reduced 🧊
🧫 What happens during the clinical and lab stages of partial denture construction?
🧑⚕️ Clinic
Primary impressions 🫳
Tooth prep + secondary impressions 🦷
Try-in metal framework 🪛
Record occlusion 🟦
🧪 Lab
Cast models + design 🤓
Make special trays 🛠️
Construct metal framework 🧲
Record rims, articulate models, set up teeth 🦷
Final fit + polish ✨
✍️ What is the purpose of primary impressions?
Taken in modified stock tray (wax/silicone/compound) 🛒
Record teeth & edentulous spaces 🦷
For study models and special tray 💡
Materials: alginate, wax, putty, impression compound
🧲 What’s the try-in metal framework stage for?
Fit check of metal framework 🧰
Add wax to simulate tooth positions 🕯️
Record occlusion in wax/mousse 🟦
🔧 What happens during articulation & set-up?
Technician replaces wax with teeth 🦷
Aligns to patient’s occlusion
Sends back for wax try-in 🔁
🕯️ What is the wax try-in for?
Check appearance 😁
Confirm bite/occlusion 🔄
Make changes easily since teeth are in wax 🕯️
