What Is A Denture ?
Dentures are removable prosthetic devices constructed to replace missing teeth and are supported by the surrounding soft tissue and hard tissues of the oral cavity. They replaces the missing tooth inside mouth to facilitate chewing without damaging nearby tissuea or of teeth.￼
Dentures can be divided into two types acording to number of teeth present in the mouth :
- Complete Dentures (CD) : When all teeth are missing or extracted ( removed) from the mouth and a prsthetic removable device is made to replace all 28 teeth inside mouth, the appliance is called Complete denture. Complete Denture replaces all the 28 teeth in the mouth in the upper and lower jaw while no other teeth is present in the mouth including wisdom teeth.
- Partial Dentures (RPD) : When a dental removable prosthesis is made to replace only some missing teeth inside mouth leaving some natural teeth aside , is called Partial Denture. Partial Dentures do not cover the entire jaws only the areas of missing teeth.
Types of Denture according to material:
1. Traditional Dentures : This type of dentures dentures are made from hard material and most widely use for making dentures because of economic reasons and preservation of alveolar crest bone. Because they are hard dentures somtimes patient need some adhesive powder to keep them in place.
Drawbacks: Hard dentures takes more time to get habitual so that patient can keep them in mouth for long period and can eat with them. In cases of Hard partial dentures metal wire clasps are required sometimes to keep them in places snugfit and to prevent from dislodging during chewing and talking. Metal Wire Clasps may be visible if the denture extends upto anterior teeth and its not a pleasing appearance. Due their hard nature they easily got brocken if mistakenly fall from hand on to hard surfaces like floors etc.
2.Flexible Dentures : These denture are made of little softer material which are flexible in nature. Metal clasps are not required for support as the clasps are made from the same plastic material. Hence appears esthetically good. Don not break on accidental falling to hard surfaces like floors . They are resistant to fracture and easily slip into the spaces in mouth and have good grip over soft and hard tissues inside mouth. Very comfortable in wearing then hard dentures even for patient who are wearing them for first time and easy to used to with them. Less period for being used to wear and eating with them.
DRAWBACKS : These dentures can not be given to patient with sugar as the boneloss beneath the flexible dentures occurs at greater speed then hard dentures. Should not be used posterior teeth with opposing natural teeth because of greater bone loss again. Should not be given for complete denture if the patient is wearing denture for first time.
3. Implant Supported Dentures : When the jaw bones are not sufficient to support a hard or flexible denture or patient is willing for fixed dentures. These dentures are best choice for such patients. These dentures are made over the implants. First the implants are placed inside the jaw bones and balls are fitted over them a new denture is fabricated with shocket insidethem over the implant area. So that when the denture is wore the balls of implant easily fits inside the shocket of denture and dont let them move the denture by will or by tongue.
DRAWBACKS : Yet no drawbacks are known for such denture. If patient keep oral hygein good and have good take care of his implants, these are best technique for fixing dentures.
4. Over-Dentures : This type of dentures are little tricky. After a tooth is removed the bone supporting the tooth is lost over the time of period. These dentures are made over the remaing roots of the teeth which can not be restored with caps. The roots are treated with RCT and then post are made over the roots and metal domes are given over the roots. Now these domes are used as implants and denture is constructed over these roots.
DRAWBACKS : Firm tooth roots and clinical mastership is required to make such dentures.
5. Cast-partial Dentures : A cast partial denture rests on a metal framework over the bone ridge that attaches to your natural teeth with metal clasp or precise attachments. Sometimes crowns are placed on some natural teeth which serve as anchors for the denture. Cast partial dentures firmly rest over the ridge and offer a removable alternative to bridges. They are most suited in pateient with some firm tooth in mouth and some missing tooth conditions(partially dentulous & partially edentulous).
6. Immediate Denture
An immediate denture is one which is immediately formed after teeth are removed. While immediate dentures offer the benefit of never having to be without your teeth. They needs to be relined after few month .The reason is that the bone supporting the teeth reshapes as it heals, causing the denture to become loose.
Which type of dentures will suit you only ur dentist can tell you after your full mouth check-up.
