✅ What is prosthetic rehabilitation?
Prosthetic rehabilitation is a branch of dentistry that aims to restore damaged or missing teeth and to restore function, aesthetics, and comfort. It is most commonly applied in cases of tooth loss, trauma, periodontal disease, or extensive carious damage.
🎯 Main goals
- Restoration of chewing efficiency
- Improvement of speech
- Restoration of facial aesthetics and support
- Maintenance of occlusal stability (stable bite)
- Protection of remaining teeth and oral structures
- Improvement of quality of life
1) Fixed Prosthetic Rehabilitation
Restorations that are cemented or fixed in place and cannot be removed by the patient.
- Dental crowns (metal-ceramic, all-ceramic, zirconia, CAD/CAM)
- Fixed bridges (replacement of one or more teeth)
- Implant-supported crowns and bridges
- Full-arch fixed restorations (e.g., All-on-4 / All-on-6)
⭐ Advantages
- High stability
- Natural look and feel
- Long-term solution
2) Removable (Mobile) Prosthetic Rehabilitation
Prostheses that the patient can remove and reinsert independently.
- Complete dentures (for fully edentulous patients)
- Partial dentures (acrylic, metal framework, flexible)
- Overdentures (supported by teeth or implants)
⭐ Advantages
- More affordable option
- Non-invasive or minimally invasive
- Easy maintenance
3) Implant-Supported Rehabilitation
Uses implants as “artificial roots” to support crowns, bridges, or dentures.
- Implant crown for a single tooth
- Implant-supported bridge
- Implant-retained overdenture
- Full-mouth implant rehabilitation
✅ Benefits
- Prevention / reduction of bone loss (resorption)
- Excellent stability and function
- No need to grind adjacent teeth
✅ What does “full-mouth” prosthetic rehabilitation mean?
A comprehensive treatment that restores both jaws and often includes occlusal analysis, correction of bite height, and a detailed plan for aesthetics and function.
🧩 Often includes
- Occlusal analysis and restoration of vertical dimension
- Temporary (provisional) restorations
- Digital Smile Design
- Multidisciplinary approach (prosthetics, periodontology, implants, orthodontics, TMD)
🗺️ Planning Steps
- Clinical and radiological examination (CBCT, digital scans)
- Assessment of the bite and temporomandibular joint (TMJ)
- Diagnosis and goal definition with the patient
- Temporary restorations
- Final fabrication (often CAD/CAM)
- Check-ups and maintenance
📌 Most Common Indications
- Partial or complete tooth loss
- Severe tooth wear (bruxism)
- Post-traumatic rehabilitation
- Advanced periodontal disease
- Congenital absence of teeth
✅ Crowns in prosthetic rehabilitation
Dental crowns are restorations that restore the shape, function, and protection of damaged teeth. Below are the most commonly used types of crowns in practice, selected based on the required strength, aesthetics, and tooth position (front or back teeth).
🎯 What do we achieve with prosthetic rehabilitation?
- Better chewing and a stable bite
- Improved speech and comfort
- A more natural appearance and enhanced facial aesthetics
- Protection of remaining teeth and oral structures
⭐ Most Common Crown Options
- PFM (Porcelain-Fused-to-Metal) crowns
- All-ceramic / All-porcelain crowns
- Zirconia crowns
- E-max (Lithium Disilicate) crowns
1. PFM (Porcelain-Fused-to-Metal) crowns
- Metal core + porcelain outer layer
- Advantages: High strength, good aesthetics, long-term proven option
- Disadvantages: Over time, a dark line may appear at the gum margin due to metal exposure.
2. All-ceramic / All-porcelain crowns
- Made entirely of porcelain or ceramic
- Advantages: Excellent aesthetics, ideal for front teeth, metal-free
- Disadvantages: May be slightly less durable than metal-based options under heavy biting forces.
3. Zirconia crowns
- Made of zirconium oxide (very strong ceramic)
- Advantages: Extremely durable, can be tooth-colored, excellent for back teeth
- Disadvantages: May cause wear on opposing teeth if not properly polished.
4. E-max (Lithium Disilicate) crowns
- A type of high-strength glass-ceramic
- Advantages: Excellent aesthetics and good strength, very popular for front teeth
- Disadvantages: Usually more expensive
📌 How is the right crown selected?
- For front teeth, priority is usually given to aesthetics (all-ceramic / E-max)
- For back teeth, priority is usually given to strength (zirconia / PFM)
- The final choice depends on the bite, the condition of the tooth, and the individual treatment plan.
✅ What are CAD/CAM crowns?
CAD/CAM crowns are dental restorations that are designed and manufactured using computer technology: CAD (Computer-Aided Design) and CAM (Computer-Aided Manufacturing). This process enables highly precise, customized crowns — often completed in a single visit.
🦷 How does the CAD/CAM process work?
- Digital scan: The dentist performs a 3D scan using an intraoral scanner (without uncomfortable impressions).
- Computer design: Specialized software is used to design the crown (shape, size, and bite).
- Milling / 3D printing: The CAM machine mills or 3D-prints the crown from a material block (most commonly zirconia or lithium disilicate).
- Placement: Try-in, adjustments if needed, and permanent cementation
📌 Materials most commonly used
- Zirconia: Extremely strong, excellent for molars (back teeth)
- Lithium disilicate (E-max): Superior aesthetics, excellent for front teeth
- Hybrid ceramics / resins: Faster to fabricate, but less durable
⭐ Advantages
- Same-day crown (often without the need for a temporary crown)
- Very precise fit thanks to digital design
- Strong and aesthetic materials (e.g., zirconia, E-max)
- Less “human factor” compared to traditional laboratory fabrication
- More comfortable experience — no impression trays
⚠️ Disadvantages
- Not ideal for all cases (complex aesthetics may sometimes require a laboratory)
- Not every clinic offers this service (specialized equipment is required)
- High initial investment in equipment (which may affect the price)
🦷 Is a CAD/CAM crown right for you?
It is an excellent option for:
- Broken teeth
- Large cavities / large fillings
- Replacement of old crowns
- When you need same-day treatment
Key: the best option is determined after a dental examination and an individual treatment plan.
✅ What are Edelweiss veneers?
Edelweiss veneers are prefabricated (ready-made) veneers intended for minimally invasive aesthetic and restorative dentistry. They are applied directly to the front (anterior) teeth for aesthetic corrections (color, shape, minor fractures), with minimal tooth preparation compared to classic laboratory porcelain veneers.
💎 Key Features
- Minimally invasive: often requires little or no tooth grinding (compared to traditional veneers)
- Fast application: in many cases, it can be placed in a single visit
- Natural aesthetics: designed to replicate the transparency and shape of natural enamel
- Direct bonding: bonded with composite material for stable adhesion
- Good durability: good resistance to abrasion and a smooth surface
🦷 Indications (when used)
- Color changes / stains and discoloration
- Minor fractures and damage
- Diastema (gaps)
- Shape and aesthetic correction
- Enamel erosion / wear
📌What to consider
- Composite veneers (such as Edelweiss) may discolor or wear over time more than porcelain veneers.
- The final result depends on the indication and the precision of the application technique.
🧱 Material and Manufacturing
- Nano-hybrid composite “shell” veneers with a structure that mimics natural enamel
- Highly filled and factory-polymerized
- Radiopaque (visible on X-rays)
- The system mentions the use of technologies such as laser sintering and vitrification.
- The surface is designed for durability and aesthetics (smoothness / gloss).
🦷 Indications (when used)
- Discoloration / stains
- Minor shape and proportion corrections
- Minor fractures / damage
- Diastema (gaps)
- Lengthening / correction of tooth edges (incisal area)
💎 Key Features
- Minimally invasive: can be placed with minimal preparation
- Fast: designed to be placed in a single visit
- Aesthetics: imitation of enamel and translucency
- Shade flexibility: veneers come in a base “Enamel” shade and are layered with a composite overlay to achieve the final color.
- Repairability: in case of minor damage, composite veneers can often be repaired without full replacement
🧩 How they are placed (typical protocol)
- Size selection: selection using a “sizing guide” according to the tooth
- Surface preparation: etching and bonding according to protocol
- Placement and bonding: the veneer is bonded directly with composite material
- Finishing and polishing: polishing the margins for aesthetics and function
📌 Important
- Placement is technique-sensitive, and the dentist’s experience directly affects the final result.
- The best results are achieved when using the entire system (appropriate bonding agents and composites), not only the “shell” veneers.
✅ What does a “mobile” (unstable) complete denture mean?
It is a complete denture that does not have sufficient retention, stability, or support , so it shifts when speaking, chewing, or smiling and may cause discomfort and reduced functionality.
⚠️ Most common problems
- Shifting while eating or speaking
- Poor chewing efficiency
- Irritation/sores on the mucosa
- Reduced confidence and self-esteem
🔎 Most common causes
- Anatomical: pronounced bone resorption, “flat” ridge, shallow vestibule, unfavorable muscle attachments
- Prosthetic: incorrect impression technique, weak “seal”, incorrect bite height, improper occlusion
- Functional: need for relining/adjustment, strong muscle activity
🛠️ Solutions
- Conservative: relining, occlusal correction, adjustment
- New denture: functional impression, correct vertical height, better “seal”
- Most stable: implant overdenture (when indicated)
🪥 Patient guidelines
- Removing at night
- Daily cleaning with a denture cleanser
- Avoiding very hard/sticky foods (especially during adaptation)
- Regular check-ups
✅ What is implant prosthetics?
Implant prosthetic rehabilitation involves replacing missing teeth with restorations supported by implants (artificial roots) that carry crowns, bridges, or dentures.
1) Types of implant-supported restorations
- Implant crown (single tooth): implant + abutment + crown (no grinding of adjacent teeth)
- Implant bridge: two or more implants support a fixed restoration for multiple teeth
- Implant overdenture: removable denture “locked” onto implants (locators/bar)
- Full-arch fixed restoration: All-on-4 / All-on-6 (when indicated)
2) Fixation methods
- Screw-retained: practical for servicing and follow-up
- Cement-retained: aesthetic, but requires careful control of excess cement
3) Typical protocol
- Planning and diagnosis
- Implant placement
- Osseointegration (3–6 months or immediate loading when indicated)
- Digital scan / impression
- Prosthetic fabrication
- Placement and occlusal adjustment
- Maintenance and check-ups
⭐ Advantages
- Preservation of bone and reduced resorption
- Excellent function and aesthetics
- Improved comfort and stability
- Long-term predictability (with proper maintenance)
🧼 Maintenance and possible complications
- Regular check-ups and professional hygiene
- Possible complications: screw loosening, prosthetic fracture, peri-implant mucositis / peri-implantitis
- Proper occlusion and patient education are important
