Prosthetics

Deals with the replacement of lost or missing teeth with fixed or removable substitutes to restore form function and aesthetics.

Fixed partial dentures

A fixed partial denture replaces one or more teeth in an arch where only some of the teeth are missing, i.e. a partially edentulous arch. The denture is fixed in the mouth and is not to be removed and replaced at will by the patient. An FPD can be

Tooth supported FPD

In tooth supported FPDs or bridges, the natural dentition is used to support the FPD. The missing teeth are replaced with metal or porcelain teeth which are supported by crowns placed on the tooth or teeth adjacent to the space. The teeth on either side of the edentulous space are reduced to create space for the crowns. After meticulous measurements are recorded, the bridge is fabricated in the laboratory. The finished restoration is then bonded to the teeth.

Implant supported FPD

In implant supported FPD, implants are used as abutments to support the bridge. Read More…

Crowns

A crown, or cap as it is commonly called is a dental restoration which completely covers or encircles the tooth or dental implant. A crown can indicated for several different situations such as to protect a weak or endodontically treated tooth, to restore a tooth which is broken or has a large filling, to hold a bridge in place, to make a cosmetic change in stained or misshapen tooth or to cover an implant. The dentist prepares the tooth to create space for the crown and records a dental impression. The crown is then fabricated in the laboratory and fixed on the tooth at a subsequent appointment. Dental crowns can be fabricated with a wide variety of materials.

Metal Crowns

The metals most commonly used for casting Dental crowns are Gold Alloys and Base metal Alloys. They have the advantage of being able to withstand biting forces while causing minimal wear of the opposing tooth. Also in comparison to other crown materials, very little tooth structure needs to be removed for the crown preparation in metal crowns. However their color is a rather major disadvantage, which makes it appropriate only for out of sight back teeth.

Porcelain fused to metal crowns.

Porcelain fused to metal crowns or Metal ceramic crowns are a much more natural looking option. Unlike Metal crowns they can be shade matched to the adjacent teeth. PFM crowns, like the name suggests have a metallic base onto which the ceramic or Porcelain is fused to obtain a natural looking crown. They are a good choice for both front and back teeth. However, they can be abrasive on the opposing tooth structure and the porcelain can chip off exposing the underlying metal. But despite those disadvantages, they are strong robust crowns which will last a long time.

All Ceramic Crowns

All Ceramic crowns or Metal free crowns are the most aesthetic restorative option in dentistry. They are made of Ceramic and no other material. The crowns are translucent which looks extremely attractive and blends well with the surrounding teeth. The fact that only porcelain is used to fabricate these crowns ensures a thin natural looking crown that is very light weight. They also have the added benefit of being “biocompatible” which means that they cause no reaction, allergic or otherwise from the surrounding tissue, allowing the gum to grow back along the crown to its original form. However these crowns lack the strength of the Metal Ceramic crowns. They are the first choice in full coverage crowns for front teeth.

Zirconia Crowns and Bridges

Zirconium crowns are often called the most aesthetic crowns available. With their unmatched strength and fit, Zirconium crowns ideal for use in any part of the mouth. The translucency is very similar to the natural tooth which makes these crowns virtually indistinguishable from the surrounding natural teeth.

Zirconia crowns and bridges are made of Zirconium dioxide, a high strength ceramic material which is used in other high tech appliances employing very advanced technology. It is often referred to as “Ceramic Steel” owing to its unusually high strength. Zirconia crowns are able to easily withstand the biting forces and every day wear and tear. It does not require a metallic framework for support. In addition to that Zirconia crowns are extremely biocompatible, with a very low risk of allergic reactions, which are quite common with base metal alloys. However all these advantages are eclipsed by its aesthetic properties. The translucency of the material allows light to be transmitted through it so that the crown picks up the color of the underlying tooth and mimicking its natural shade. Zirconia is an insulator and hence protects the tooth from thermal insults from hot and cold foods. It is also kind to the gums and you won’t see any gum recession or black line with Zirconium crowns and bridges.

Removable partial dentures


A removable partial denture is an appliance that replaces one or more missing teeth for function and aesthetics and takes its main support from the mucosa. It can be removed and replaced in the mouth at will by the patient without professional assistance. Removable partial dentures are indicated for patients who do not have the necessary tooth support for a fixed partial denture of bridge or are not good candidates for the placement of implants. A removable partial denture consists of an acrylic pate that adapts to the palate or gums and mimics gingiva. Other metal components also form a part of the removable partial denture and provide retention and support. The process of fabrication requires multiple appointments with the dentist for measurements and trails. The main advantage of removable partial dentures is that it allows for excellent oral hygiene maintenance on account of being removable. Also no extensive preparation of surrounding teeth is required as in case of a fixed partial denture.

Flexi-dentures

Flexible dentures are made with a nylon thermoplastic denture base resin which is biocompatible and has adequate strength so as to be able to withstand the forces of regular use. It has unique physical properties. The thermoplastic resin is relatively translucent and allows the patients gums to show through the denture base becoming inconspicuous in the mouth. They are light weight as a result of lacking the metal framework that is essential to the conventional cast partial dentures and very comfortable for the patient. Flexi dentures also provide a better fit and retention in the mouth giving you confidence while eating, smiling and talking. These dentures are both aesthetically and functionally superior to any other removable dental replacement.

Complete denture



A complete denture is probably the first image that comes to mind when one thinks of dentistry. They are one of the oldest dental prostheses, used in one form or another since ancient times. While our distant forefathers once used wooden dentures made of animal teeth, modern dentures are fabricated using the latest technology in laboratories. Complete denture fabrication is a complex process that involves recording dental impressions and jaw relations over the course of several appointments. These dentures are advised to patients who have lost all the natural teeth in the upper and/or lower arches. Acrylic is used to make the gum part of the denture while resin or porcelain teeth for the tooth replacements. The dentures get their support from the mucous membrane and underlying bone. A properly fabricated denture not only replaces teeth but also preserves the alveolar bone. However, patients being unused to having a large prosthesis in their mouths, need to have the physical and psychological ability to adapt to the denture.
