DENTAL CROWN TYPES AND COST IN NAGPUR INDIA : A COMPLETE GUIDE
What Is A Dental Crown
Dental Crowns or Teeth Caps are the restorative and prosthetic solution to restore the appearance and function of your damaged or missing teeth.
When your nearby dentist suggests capping for your teeth and tells you about the various options you might can get confused like which material you should go for, the technique involved in the manufacturing of teeth cap, and of course the cost of teeth capping procedure in Nagpur India
This brief guide will help you to understand the dental crown, materials, procedure, and to select the right one according to your need.
Why You Should Get Your Teeth Capped:
There are many other forms of restorative options available for your pearly whites in dentistry like Teeth Filling, Inlay, Onlays, Bonding, and Veneers
So, after examination, your prosthodontist might suggest you go for a dental crown for the following reasons:
- Severely damaged or weakened tooth after decay or trauma
- Severely attrited and worn-out tooth.
- Teeth cap over a Dental Implant
- To strengthen your tooth after Root Canal Treatment especially the back chewing tooth.
- For cosmetic reasons to change the form and aesthetics of severely rotated and malpositioned teeth.
- For bite alignment in some cases.
- To replace missing teeth by Dental Crown And Bridge procedure.
Teeth Capping Procedure:
If you are in a need of dental crown allow your dentist for a couple of visits to complete the treatment. For your first visit, the doctor will numb the area around the tooth, if required to prevent any discomfort. Then S/he uses dental instruments to form and prep the tooth so that crown fits properly.
Sometimes additional procedures may require to ensure a good fit and retention of the crown like a build-up to help support the crown or crown lengthening to increase the height and surface area of remaining teeth structure for good retention.
After the tooth is prepared following standard protocols a mold of the tooth is taken a temporary crown is placed chairside to guard the prepared tooth until the permanent crown is received from the dental laboratory.
The mold or cast is sent to a dental laboratory where a customized crown is made just according to teeth size and fit.
Once the dental office receives the crown from the lab you will be able to get your delivered. If you are satisfied with your crown shape, color, and fit the crown will be permanently cemented on your second visit. However, the crown received from the laboratory may not fit well, as the doctor and you expected to. To achieve optimal results another mold or bite is taken for modifications or replacement to ensure proper fit, bite, and aesthetics.
Although rare, sometimes you may feel some discomfort, soreness in gums, and raised bite for a few days and usually subsides on its own or may require minor adjustments.
What Are Different Types Of Dental Crowns And How to Select the Right One For You
Teeth caps can be primarily divided into two types
Temporary Dental Crowns:
- The temporary teeth caps are basically given for a limited time period a few days to a few weeks. They are mainly composed of tooth-colored soft resin material (acrylic). These caps are soft, porous, easy to cut, and can be carved chairside
- Nowadays PMMA Dental Crowns (Poly Methyl Meta Acrylate) are given which are manufactured by CAD/CAM technique for a provisional prosthesis. These provide superior aesthetics and strength when compared to acrylic crowns
- As the name suggests temporary caps are given for a transient period of time till the permanent prosthesis is made.
Uses of temporary Dental caps:
- As a transient dental cap given immediately after tooth preparation for teeth protection, function, and aesthetics
- Immediate chairside tooth crown right after placement of dental implants and is replaced by a permanent one after dental implant fuse to the jaw bone.
Note: These Provisional/Temporary crowns made to use until the permanent cap is finished and will have no warranty. Since it is made of Acrylic (Plastic) it may break, or get discolored.
Permanent Dental Crowns:
These are the definitive prosthesis which is given to provide function and aesthetics to the tooth structure. Due to advancements and engineering today we have a variety of permanent dental caps. One can select the right dental cap on the basis of their need, material, technology, and Dental Crown cost
The Different types of crown based upon materials that are widely used in Dentistry in India are:
Porcelain Fused to Metal Dental Crowns (PFM):
These are the most widely used dental crowns in India. They are made up of metal as the base to provide strength and is layered by the tooth color porcelain for aesthetics.
Metal Base is made by lost wax technique or CAD/CAM technique
Advantages of PFM Teeth Caps
- Superior Aesthetics when compared to All Metal Crowns
- High Strength
- Less costly when compared to Zirconia or All-Ceramic crowns.
Disadvantages Of PFM Teeth Caps
- Less aesthetic when compared to Zirconia or All-ceramic crowns
- Leave Bluish Black discoloration in gum lines, not suitable for front teeth with a gummy smile
- May cause allergy due to Nickle present in the metal alloy in susceptible patients.
- Sometimes porcelain gets chipped off from metal surface leaving the metal surface exposed leaving the unaesthetic appearance
- When the metal base is manufactured from the lost wax technique may cause casting defects in metal such as Shrinkage of cap margins leading to misfit, Metal porosities which can weaken the crown
Advancements in PFM Crowns
- Nowadays base metal structure which is an alloy of Cobalt-Chromium-Nickle is replaced by Titanium which is highly biocompatible and light in weight.
- Nickle free alloys are used
- CAM/ CAM technology is used (DMLS Crowns) which provides a better fit. As they are machined carved no casting defects are seen such as short margins or metal porosities.
Zirconia Dental Crowns
- They are the most trending and upcoming dental prosthesis nowadays.
- They bear the strength of PFM crowns and the aesthetics of all ceramic /porcelain crowns.
- The caps are directly carved out by Zirconia blocks by CAD/CAM technology so the chances of marginal error are very less
- They are highly translucent, lightweight, and provides Good Aesthetics.
- They are highly biocompatible. tissue loving and least likely to cause allergic reactions.
- The cost of zirconia caps is high when compared to PFM or metal crowns.
All-Ceramic Dental Crowns / E max / Lithium Di Silicate Dental Crowns
Advantages Of All-Ceramic Teeth Caps
- These are completely made up of porcelain and provides excellent aesthetics
- They are biocompatible as they don’t have any metal structure
- Emax crowns are the type of all-porcelain crowns contains lithium disilicate and provides excellent aesthetics
- most preferred for the single cap in the front tooth
Disadvantage of Ceramic Crowns
- Less fracture resistance
- Can be a failure when used as multiunit in bridge
- They are made up of metal alloy such as cobalt-chromium-nickel and have high strength but poor esthetics.
- Can only be placed in back teeth which are not in the smile line
- Not recommended in patients with Nickle allergy.
- Nowadays Nickle free or Titanium alloys are available for metal teeth cap which is more biocompatible
- Cost-wise they are the cheapest permanent dental crown.
Gold dental crowns come under a variety of metal caps. they have several advantages such as they are strong and resistant, minimal tooth preparation is required.
The main disadvantage of gold teeth caps are its high cost as gold prices are too high and they require 4-6 gms of gold apart from manufacturing cost and also they are only preferred for back teeth due to poor esthetics
Teeth caps for kids milk teeth
Stainless Steel Crowns
- They are pre formed crowns in the form of metal shells in varying sizes available for the protection of milk teeth and are most commonly used for back milk teeth
- They are a durable, strong, moisture-resistant, and cost-effective option for milk teeth.
Strip Crown/ Composite Strips:
- These Polycarbonate crowns are like preformed clear shells that are filled with tooth color composite and fitted over milk tooth
- They are mostly used for front teeth and are good in aesthetics
Techniques Involved In Manufacturing Of Teeth Caps
Basically there are 2 methods
- Manual or Lost-wax technique: Here a wax coping is prepared and melted. the space created is filled with molten metal and is allowed to cool down and solidify. They inherit some of the casting errors such as porosities, Shrinkage of the metal structure, and defects which can lead to a marginal gap between tooth and cap and can cause tooth decay and gum problems later on.
- CAD-CAM Technology for Dental crown: It is the most advanced and preferred technique for teeth cap manufacturing. here the metal or zirconia is carved out directly from ingots using computerized scanning and milling. as there is no casting involved so the risk of casting error is also not present. They are properly adapt to tooth margins and lessen the chances of tooth decay and gum infection.
Cost Of Dental Crown In Nagpur India:
The cost of teeth caps in India is largely dependent upon the type of material chosen, laboratory cost, technique involved, warranty period, and additional procedure such as fillings, core build-ups, crown lengthening.
Cost based on Teeth Cap Material:
As already been discussed the cost of All ceramic and Zirconia Caps caps are higher when compared to porcelain fused to metal or all-metal crowns
The cost of Porcelain fused to metal and metal caps is also varied depending upon the type of metal used such as titanium alloys and precious metal alloys are costly than Co-Cr alloys.
Cost based on Technique of Manufacturing:
The cost of dental crowns manufactured by CAD/CAM technique is higher than those that are manufactured by manual molten wax technique.
Warranty on Dental Caps:
Nowadays the dental laboratories provide warranty on dental crown ranging from 5 to 15 years or maybe lifetime and the cost increases with warranty tenure.
Additional Procedure: Sometimes it is necessary to perform some additional procedures such as crown lengthening or additional fillings and tooth buildups to provide optimal results which may have additional procedural/material cost
The Average Cost of Dental Crowns in Nagpur India may range from 2500-15000 INR.
Are Dental Crowns Safe With Diagnostics like CT Scan & MRI
Medical imaging is a very useful tool for diagnosing a medical condition and patients often have to go under these types of diagnostic imaging. There is a common question which is asked whether dental caps are safe with these modern imaging machines
To answer this we have to understand the working principals of CT Scans and MRI
Computed Tomography Scans and Dental Caps:
CT scan uses radiation that passes through the body and depending upon its absorption by different densities the differentiation of body parts can be ruled out. Most of the Permanent Dental crowns are radioopaque and may cause some image distortion in nearby sections. Nowadays with newer advanced CT scan machines, these artifacts are minimal. So The CT scan of the face with Teeth caps are completely safe and do not possess any difficulty in diagnosis.
Magnetic Resonance Imaging(MRI) and Dental Caps:
MRI is a very useful diagnostic tool that uses powerful radio waves and magnetic fields to create images of body tissue and organs. impact of magnetic forces on dental materials may sometimes cause Projectile accidents, Thermal Heating, Prosthesis Failure, and Visual Artefacts.
Cobalt-Chromium and Stainless Steel are not compatible with MRI
For Safe MRI Scans, whenever feasible, Choose All-Ceramic caps or Zirconia Caps over Metal Caps or Metal Ceramic Caps
Complications or Problems with Dental Crowns:
Tooth Sensitivity or Tooth Pain
Tooth sensitivity can occur in the tooth which is not Root Canal treated and Dental Cap is advised to support a bridge or large restoration. Usually, the sensitivity subsides in a few days after the fixing of the cap. But if you feel extreme pain while biting or continuous sensitivity contact your dentist immediately.
Inability to Bite Properly or Change in Bite
You may feel your bite is high immediately after fixing a new cap. This can be easily adjusted by checking and removing the high points on your cap. After cap fixation, the feeling of newness can be there and one should adapt to this in a few days. In case you still feel the change in bite visit your dentist for checkup and adjustments
Tooth Decay /Tooth Fracture
Sometimes there could be the decay of tooth structure beneath the cap either due to marginal gaps or gum recession, which can ultimately weaken the tooth and lead to its fracture. The marginal fitting of dental caps is better in computerized sintering technology (CAD/CAM) than manual manufacturing. Also, it is advisable to take care of your teeth and gum health regularly to avoid gum problems. In case you feel frequent food lodgement around your artificial teeth schedule your appointment with your dentist for a checkup.
Blackening of the Gum Line and Allergic Reactions
Pigmentation of gums surrounding dental caps and Allergies is commonly seen in Chromium-Cobalt-Nickle metal or metal-ceramic caps. The best solution is to choose an all-ceramic or Zirconia caps as they are tissue loving compared to base metal alloys
The ceramic portion of the dental cap may be chipped off while bitting on something hard or by natural wear over the period of time which may look unpleasant and feels rough. It is advisable to go for quality dental crowns with a warranty, which can then be replaced without lab costing
Dental Crown Coming Out/ Crown Dislodgement
Although these caps are cemented with very strong dental cement. but over the period of time may come out especially while having sticky foods like gums or eclair, which can easily be re-cemented, If the crown dislodgement is frequent then crown heigh should be looked for the as a short crown have less support for retention. For this problem, an additional procedure like crown lengthening (Increasing tooth height) is recommended, or other options like inlay or onlay are recommended.
Special Care for Dental Crown:
- Brushing your teeth at least twice daily,
- Flossing daily around the crown area where the tooth meets the gum
- Daily rinsing with an antibacterial mouthwash.
- Use an interdental brush or Water flosser as recommended by the Dentist
