Crown & Bridge

Crown is a fixed dental prosthesis used to restore a damaged tooth or cover an implant. It resembles the lost, damaged or missing tooth and helps in restoring its shape, size and function. Bridges on other hand are fixed dental prosthesis used to replace one or more missing teeth by joining fabricated teeth with adjacent teeth or implant.

A dental crown may be required to protect a weak tooth from breakage, to restore an already broken tooth, to cover and support a tooth with a large filling, to cover misshaped or severely discoloured teeth, to cover severely attrited tooth, to cover a dental implant or to make a cosmetic modification.

Cons with Metal Crowns:
In recent time, magnetic resonance imaging (MRI), has become a common medical diagnostic imaging tool. Since it uses powerful magnetic fields to create images of the inside of the body, there have been concerns about the safety of metal objects like fillings, implants, and crowns in patient’s mouths. A few different factors determine if dental crowns and MRI are a bad combination.
Even if a crown is not pulled out, it can still be damaged. The strong magnetic field of the MRI machine can interact with the metal, causing it to vibrate. This vibration can move, bend, or break dental restorations. Even if a certain metal isn’t attracted to a magnet, it can still pose a danger. Some metals absorb the energy created by the magnetic field. This energy can heat the metal enough to cause burns on the surrounding tissue in the mouth.

Following are the different types of dental crowns:

 Stainless Steel crowns: These crowns are generally used as permanent crowns in children. These crowns are ideal for restorations in children as they are prefabricated and don’t require multiple visits to the dentists. They are cost effective and usually come off along with primary teeth as they shed off to make space for permanent teeth in the oral cavity. Stainless steel crowns are often used as temporary crowns in adults, till customized crowns are fabricated.

 Metal Crowns: These are generally made from alloys that are noble or base-metal alloys. Metal crowns are ideal choice for restoring molars as they can resist biting and chewing forces, and don’t break or chip off easily. Since they aren’t tooth coloured crowns, they cannot be used to restore front teeth. In our practice we consider these crowns as out-dated.

 Porcelain-fused-to-metal Crowns: PFM crowns provide best of both the worlds. They have metal’s strength and porcelain’s aesthetics. After all ceramic, PFM crowns are the second best in terms of providing natural tooth like colour.
Disadvantages of Porcelain fused metal (PFM) crowns:
 Aesthetic limitation as they have metal framework and opaque layering of porcelain reflecting metal greyish shade
> Ceramic chipping under pressure and leading to entire crown replacement.
> Wear antagonist natural teeth
> Increased plaque accumulation
> Not recommended to metal allergic individuals.

Emax crowns: These crowns are strong as well has natural tooth like appearance due to light transmitting quality. They are the latest cosmetic porcelain. E-max is an all-ceramic crown that is based on lithium disilicate glass. The crown is usually milled from a single block of ceramic, which makes it very tough and durable. E-max is extremely durable and highly aesthetic; hence it is widely used for restoring teeth in the anterior (front) region as it gives best match to your natural teeth.

Empress Crowns: Empress Crowns provide utmost aesthetics due to its close resemblance to natural teeth. However these cannot be used to restore back teeth which are subjected to high occlusal forces due to less strength of material.

 Feldspathic Crowns: These crowns are believed to be the most beautiful porcelain crowns. However these are technique sensitive and are used by only by skilled dentists and laboratory technicians.

 Procera Crowns: Procera is an all-ceramic restoration that has successfully taken metal out of the mix in the production of dental crowns. They are made with an aluminium oxide as base coping that is custom milled with CAD technology and a superficial stacked translucent porcelain layer that is used to make the restoration attractive and lifelike. They are biocompatible and its tissue-friendly material encourages gums to grow back around the tooth. It can be used for front as well as back teeth restorations of crown and bridges.

 Zirconium Crowns:  Zirconium crown is a CAD CAM milled all-ceramic crown that are mainly used for front and back teeth crown and bridges and as implant abutments. There are many brands of this product and some have higher clinical success rates. Some of these are 3M Lava, Cerec, Bruxzir, etc.
Patients who wish for excellent dental restoration should always choose zirconia crowns over conventional porcelain fused metal crowns (PFM) or full gold crowns due to their superior strength, durability, and excellent aesthetics. For fixed dental restoration always prefer zirconia crowns and bridges, as they possess excellent aesthetics and have good strength, zirconia is the most popular material for making dental crowns and other restorations in back teeth.
There are two types:
cosmetic tooth coloured filling restoration crowns best aesthetic dentist india ahmedabad satellite denal clinic porcelain veneer smile designing (4)Solid /Monolithic zirconia: They are opaque generally for posterior teeth, making it durable to withstand forceful chewing and grinding. They are effective for masking highly discolored dental restoration such as post n core or restoring dental implants.
Layered zirconia: They are more translucent and opalescent, unlike solid zirconia, it is especially suitable for anterior crowns. Although if enough clearance is present can be used for posterior teeth.
> These crowns are 100% metal-free, prevent gingival darkening, and remove the possibility of exposing metallic margins if gum recedes.

Denture is the prosthetic device used to replace the missing teeth and restore their structure and function. They either replace all the teeth or set of missing teeth depending on denture type. Denture enables you to speak and eat more comfortably. They prevent facial muscles from sagging and impart an overall younger look to you. Following are the type of dentures:

Full Dentures: These dentures replace all the teeth in the mouth. These can either be Biofunctional Prosthetic System (BPS) Dentures, Lucitone dentures or regular dentures.

BPS Dentures: These dentures ensure that the aesthetic demands of the patient are fulfilled with its set of Ivoclar Vivadent set of teeth which resemble the natural teeth and help to recreate your lost smile. They are customised according to your needs and requirements and precisely fit onto the gums without snapping. They enable you to consume the food of your choice without creating any sort of hindrance. Besides rendering excellent aesthetics, these dentures also restore the function of the natural teeth.

Lucitone dentures: These dentures are made with lucitone denture base resins which is high impact denture base resin which resists any sort of breakage. It is highly aesthetic with balanced translucency and excellent vein simulation.

However these dentures cannot be used in patients who have strong gag reflexes or are allergic to the monomer present in the denture base resin.

Partial Dentures: These removable dentures used to replace one or more missing natural teeth and thereby prevent the adjacent remaining teeth from shifting, restores function and aesthetics. Following are the types of partial dentures.

Flexible Partial Dentures: They are the type of partial dentures which are extremely comfortable on wearing owing to their flexible nature. Flexible denture is the ideal choice for patients allergic to the acrylic resin. They are light in weight and provide a more realistic look. They restore the structure and functions of the missing teeth and prevent adjacent teeth from shifting. However, these dentures are more prone to the bacterial attack, and hence need to be cleaned frequently.

Cast Partial Dentures: It is a removable type of partial denture which consists of a cast metal framework, which contains artificial teeth set in acrylic resin. These dentures are more retentive, much stronger and durable. However, this denture is very fragile and almost impossible to repair once damaged.

Implant Dentures: These dentures are supported by and attached to the implants. These can either be fixed or removable depending on the type.

Implant Supported Fixed Dentures: These dentures are fixed to the permanent implants providing a more secure and confident fit. They enable you to eat and speak properly without slipping away. It replaces all the missing teeth and increases your self-confidence. These dentures may however lead to food lodgement if not cleaned properly.

Implant Supported Removable Dentures: These dentures can either be bar retained or ball retained.
I.Bar Attachment Denture: This denture involves placement of 4 to 6 implants depending on the size of the jaw. Thin metal bar that follows the curve of your jaw is attached to these implants using clips or other types of attachments. The customised denture is then fitted over the bar clipped into place by the attachments. This denture can be removed for cleaning and maintenance.
II.Ball Attachment Denture: This denture snaps onto the implants placed into your jaws. The attachments on the implants are ball-shaped which fit into the sockets of the denture. It thereby helps you to chew food without sliding away. It is not as stable as the bar retained denture and still has the ability to move.

Teeth Care Centre® has wide array of options to suit your requirements, so that one can eat favourite food without worrying.

Inlay and Onlay

Inlay is an indirect (laboratory made) restoration used to restore posterior decayed or damaged teeth, in which the damaged portion is too extensive to be treated with simple filling. It will incorporate and restore chewing surfaces of the teeth between the cusps.

While onlay is an indirect (laboratory made) restoration which is used to restore posterior decayed or damaged teeth, in which the damaged portion is not extensive enough to need a full coverage crown. Onlays will restore and incorporate one or more cusps.

Based on the nature of material used in their fabrication, inlays can either be gold type, porcelain type, composite type and zirconium type. Porcelain, zirconium and composite inlays are much more aesthetically appealing than the gold ones due to their close resemblance to the natural tooth colour.

Inlays and onlays do not require removal of healthy portion of tooth and thus helps in preservation of natural tooth structure. Porcelain and zirconium inlays do not chance colour over time and are aesthetically appealing. Margins of both inlays and onlays are kept minimal which makes them easier to clean and further help in maintaining proper oral hygiene. Moreover they restore and strengthen the damaged tooth.

Teeth Care Centre® are known to incorporate latest dental technologies in our clinic and therefore we use the latest CAD/CAM technology to design and fabricate a custom inlay or onlay. This means you can leave the dental office with fully aesthetically restored tooth.

Implant Prosthesis


The selection of abutments are based on the following factors

These abutments are preferred in the front teeth aesthetic zones, owing to their tooth coloured nature.

These abutments are not aesthetic and are generally used in the back teeth region.

– Easily retrievable
– Easy to tighten the screws if the prosthesis becomes loose
– Abutment removal during maintenance of implant is possible
– Chances of composite coming out of screw access hole or getting stained over time
– Less aesthetic due to visibility of filled screw access hole on occlusal surface

– These abutments are generally preferred in the aesthetic zones since they appear aesthetically pleasing
– Not easily retrievable and in cases of loosening of abutment screw – new prosthesis needs to be fabricated.
– Excess cement can extrude into the sulcus and can damage the peri-implant tissues.

This choice is solely decided by the dentist based on the requirement.

Stock abutments are the ideal choice of abutments for most cases. They come in standardized sizes for bone and tissue level implants. They are user-friendly and are often an economical choice. Straight and angulated are the two kinds of stock abutments available.
One more type of stock abutment is Multi-Unit abutment which is used in specific cases. Multi-Unit abutments are designed for angle corrections and provide positive uniform seat for screw retained implant restorations.
With stock abutments, sometimes it is also not possible to control the final margin for the placement of crown.

Custom abutments are suitable for cases which are not ideal for the stock abutments. They can provide more predictable aesthetics and superior tissue management than stock abutments. They are highly efficient but more costly.

Implant dentist will decide full mouth implant prosthesis basis on number of implants, position of implants and for long term implant health.
