Prosthodontia

It is a science in dentistry for replacing teeth by partial removable dentures, or complete dentures, or over dentures, or fixed dentures or implants, crowns & veneers for RCT treated teeth or fractured teeth.

There are different types of partial dentures

RPD Acrylic Denture

RPD Acrylic Denture

• Made of chrome cobalt alloy
• Denture holds from remaining teeth with the help of metal clasps
• To avoid metal visibility clasps can be covered with tooth colored material
• Adapt well to patients
• Disadvantage is heavy and no adjustments can be done
• Additional tooth cannot be added to existing dentures
• Expensive

Monomer free Dentures RPD Dentures

• Biofunctional Prosthetic System (BPS)
• Made of monomer free materials
• Given to patients having allergic to Acrylic denture monomer
• Disadvantage is expensive, need special equipments to process in dental labs.

• Made of unbreakable monomer free material
• Due to its flexibility, less rigidity, less bulkiness, patient feels very comfortable.
• No metal clasps
• Retention is by extending denture part itself

• Given when back teeth are missing
• Precision attachment are given depending on number of teeth to be replaced, as one or two precision attachments
• One part is fixed to natural teeth crowns attached called as (male part)
• Other part is removable part for missing teeth made of acrylic with acrylic or porcelain teeth are called as female part.
• Comfortable to Patient because of no palatal covering
• Disadvantage is expensive

• Need to change after few years
• Because sitting ridges are resorbed (size reduced)
• Denture become loose and edges can injure tissues and cheek causing ulcerations
• When acrylic teeth are worn out can reduce the vertical height and make patients to bite with strain

• Helps for stability, less chance of shifting in mouth, prevent dislodging when tongue lifts, better acceptance of the denture.
• Given more in lower jaw, when tongue tries to move, denture will be dislodged.
• Done by retaining RCT treated teeth for post insertion
• Lower dentures fits on top of the posts called over dentures

• Given for better retention of dentures
• Easily available denture adhesive is powder type
• Disadvantage is powder gets dissolved and denture becomes loose.
• Poligrip Or Fixodent gel type denture adhesive do not dissolve in saliva
• Holds dentures and gives confidence to patient.

• Crown or cap is fixed for strengthening damaged tooth treated with RCT
• To improve appearance, shape for malformed tooth

• Bridges given if one or two teeth are missing by getting support from healthy neighboring teeth either side of missing teeth
• Cantilever Bridges given if back teeth are missing by getting minimum 3 support from front of missing teeth
• Missing teeth causes remaining teeth to rotate or shift into empty space or opposing teeth will supra erupt and close space which can impinge the gums in the space
• Imbalance caused by missing teeth can lead to gum recession and TMJ disorder like TMJ dysfunction syndrome
• Ceramic shade for crown and bridge are selected with help of ceramic shade guide

• Bridges given if one or two teeth are missing by getting support from healthy neighboring teeth either side of missing teeth
• Cantilever Bridges given if back teeth are missing by getting minimum 3 support from front of missing teeth
• Missing teeth causes remaining teeth to rotate or shift into empty space or opposing teeth will supra erupt and close space which can impinge the gums in the space
• Imbalance caused by missing teeth can lead to gum recession and TMJ disorder like TMJ dysfunction syndrome
• Ceramic shade for crown and bridge are selected with help of ceramic shade guide

Nickel chromium metal with acrylic facing Crown & bridges are condemned universally because of ware and tare of metal and Acrylic which will expose sharp metal causing Ulceration which may lead to oral cancer

• Avoid chewing bone , ice, pencil or any hard objects like nuts
• Avoid sticky foods like Aluva, chocolates, chewing gums can dislodge the crowns or bridges
• Keep the areas clean by using inter dental brush, use dental floss, use mouth wash or salt gargle every day

• Solve the teeth irregularities and create a pleasing smile.
• Thin all porcelain wafers or porcelain pieces placed over the visible front teeth given to upper teeth to change colour or imperfect or oddly shaped teeth or crooked teeth, or with small holes, or having inappropriate sizes or teeth are two small or having uneven surfaces or chipped, broken teeth or discoloration due to Tetracycline antibiotic or by flurosis.

• Less tooth reduction than crowns
• Difficult to stain and are more durable
• Correct alignment of the teeth called ‘’ Instant braces”
• Brightness your smile and improves self esteem
• Closes gaps between teeth
• Translucence texture gives appearance of natural enamel
• Lengthens and reshape teeth

• Given when crown is fractured
• Are inserted into RCT treated tooth’s canals and post are cemented
• After fixing the post and core build up is made by miracle mix or composite or glass Ionomer material

• If crowns is fractured and if pulp not involved
• Made of stainless steel or gold plated titanium pins
• Self shredding pins are broken off from above the hole of crown leaving pins helps in strengthening the restorations.

• Dental Implant can be given for single crown
• Implants are made of small titanium screw as cylinder placed in upper or lower jaw bones
• Implant replace root of missing tooth, providing an anchor of your new tooth

• Implant replace root of missing teeth, by providing anchor for new teeth
• No need to involve the neighboring teeth of missing teeth
• Implant gives natural appearance and gives confidence to eat foods.

Dental implant is a 3 part processes can take several months

• 1st Step Given after taking CBCT scan and by 3 D Planning. A screw is inserted surgically into bone to prevent gum tissue or debris entering. Allow to remain for a 3-6 months where implant fuses with bone
• 2nd step Doctor attaches a post to implant. Gum tissues are allowed to heal. Post serves as a foundation for new tooth.
• 3rd step Doctor make artificial tooth called dental crown and attached to implant post
