Dental implants are the latest tread in prosthetic dentistry these days. Dental implant is small titanium screw like insert placed into the jaw bone to support a crown or removable or fixed denture.
Implant served the purpose of natural tooth roof, after placement of an implant, jaw bone grows around it to form very strong bond with the threads of an implant, the process is called as osseointrgration.
Dental implant is a best long lasting solution to replace missing tooth without any side effects on adjacent or opposing tooth.
Indications of dental implant -
Implant is an ideal solution for replacement of single tooth without taking any support from adjacent teeth or gum area.
Here multiple individual implants are placed to replace a set of multiple missing teeth.
Whenever patient wants replacement of multiple missing teeth then the treatment cost can be reduced by doing an implant supported fixed bridges. Instead of placing individual implant for each missing tooth, 3 unit bridge or 3 joint crowns are fixed onto the two implants separated by a space of single missing tooth. Middle crown reduces the cost of implant required in that area.
Implants can also play a significant role in complete denture treatment. Some patients will not be able to wear their dentures irrespective of its perfect contour and designing. These patients always complain of loose fitting denture, such patients are termed as “mal-adaptive” or some patients want their dentures to be fixed. The implant supported denture can be designed for these patients.
It is prosthesis which literally bridge the gap created by one or more missing teeth. A bridge is made up of 2 or more joint crowns (tooth caps) for the teeth on either side of the gap. These 2 or more anchoring teeth are called “abutment teeth” and false tooth in between.
The only disadvantage of bridge is; it requires trimming of healthy abutment teeth.
i) Removable partial denture-
Is a denture for partially dentulous patient who desires to have replacement teeth for functional or aesthetic reasons and who cannot have a bridge for any no. of reasons , such as a lack of required teeth to serve as support for a bridge or compromised bone supported weak teeth which cannot be taken for anchorage.
RPD usually consist of replacement teeth attached to pink or gum-colored plastic acrylic bases. Depending on your needs, we will design a partial denture for you.
ii)Cast Partial Denture-
It is a modified design of removable partial denture in which denture base is supported and strengthened by underlying custom fabricated metallic framework. Denture teeth and gum colored plastic are added to this framework to complete the appliance.
Cast partial metal dentures generally considered to be the more permanent partial denture unlike plastic partial dentures are clipped to the natural teeth with clasps and most importantly incorporate rests on the teeth.
-Advantages of cast partial denture over conventional removable partial denture.
iii) Complete dentures-
Complete denture is a prosthetic device constructed for replacement of entire dentition and associated structures of the upper and lower jaws. They are supported by the surrounding soft and hard tissues of the oral cavity.
iv)Tooth or Implant supported overdentures-
It is basically a complete denture which fits over and receives partial support and stability from one or more modified natural teeth or implants.
The stress concentration while chewing can be shared between denture bearing areas and natural teeth or implants, hence overdenture can reduce the impact of residual bone resorption, loss of aesthetics and compromised mastication (chewing).
-Advantages of overdentures over conventional complete dentures.
v) Flexible Dentures (Valplast) -
Valplast flexible denture are made up of biocompatible nylon thermoplastic resin material with unique physical and aesthetic properties. It allows patient’s natural tissue tone to appear through material. They are ideal for partial dentures and unilateral restorations.
