Hyderabad Dental Laboratory was the first dental lab to be established in the state of Andhra Pradesh. Since its inception in 1965, HDL had constantly had its finger on the pulse of the dental world, being a pioneer, a trend-setter in the world on dental prosthetics in Hyderabad. HDL boasts the latest state-of-the-art equipment and we are constantly in the process of updating our technology. Our technicians, in addition to being trained and certified at some of the top Indian Universities have also trained under some of the pioneers in the field of ceramics in Europe and USA.
HDL has been the first to launch Ceramic crown and bridge techniques outside Mumbai, and also the first to provide All-ceramic laminates, onlays and inlays in south India. In keeping with decades of tradition, HDL is always looking to broaden our horizons, having recently added a CAD-CAM unit tour facility.
Computer aided designing and computer aided manufacturing is a relatively new advancement in dental prosthetics. It utilizes computer technology for the designing and production of various dental restorations like crowns, bridges, inlays, onlays, veneers and orthodontic appliances. CAD-CAM technology allows the dentist or dental lab to fabricate esthetic and well-fitting dental prosthesis in a matter of hours. It differs from conventional laboratory techniques in that it is quick and reliable making the need for an interim temporary restoration obsolete.
CAD-CAM involves designing and fabricating the restoration with the aid of a computer software that directs every step. A digital image of the prepared tooth or teeth is obtained which is displayed as a 3-D image on the computer screen. This 3-D image is called a “Digital impression”. The data from this digital impression is transferred to the computer, where the software designs a restoration for the damaged or missing part of the tooth. A virtual restoration. This data is then sent to the milling machine where a solid block of resin or ceramic is carved into the desired shape as designed by the CAD-CAM unit. Stains and glazes are added by the laboratory technician subsequently to give the prosthesis a more life-like appearance. This entire process can be completed in a matter of hours as opposed to days to weeks that would be required if conventional restorative techniques were used.
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 wont see any gum recession or black line with Zirconium crowns and bridges.
In addition to the conventional compression molded dentures, HDL also fabricates dentures employing the rarely used injection molding technique. Essentially it involved injection of the denture base resin into the mold cavity under pressurized conditions, much like casting a metal. The resin is allowed to polymerize and during this polymerization process additional resin is injected to offset the shrinkage that takes place in conventional compression molding techniques. The result is a denture that fits much more accurately and reproduces fine details exactly. Also there is minimal exposure to the liquid portion of the resin which can cause allergies in many people. Injection molding technique allows the denture to be made very thin and light weight while still maintaining its strength. This technique is often used in the fabrication of thermoplastic flexible 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.
