Implant-Supported Overdentures vs. Implant-Retained |

Implant-Supported Overdentures

Overdentures are defined as the removable dental implants or prosthesis which cover your oral cavity. If for some reason you have lost your natural this could be because of any reason like you might have faced an injury or it can be due to medical reason. In this case, dental implants or overdenture are used.

Mainly if you have lost one or more natural then they are replaced by simple crowns or bridges respectively. But if the case is much severe then overdentures are used. For example, if a person has lost his upper front tooth because of some disease then overdentures will be done.

Previously, only bared teeth with questionable prognosis were usually used as a protector of the prosthesis. Recently, there has been an increase in the use of implant overdentures with hybrid prostheses. Submucosal roots with magnets 15, 16 are also still in use. For natural retention of the bare tooth, the goal is to protect the canines from second premolars on both sides of the arch. The teeth are dome-shaped 2 3 mm above the gingival level with occlusive constriction. To address some defects of the exposed teeth, such as caries sequence, tooth abrasion, metal aligners short and long were used on the prepared dome teeth.

Retention of the submucosal root reduces each patient’s oral hygiene responsibilities but delays the resorption of the remaining alveolar process. Thanks to immersion in water, they avoid the effects of poor oral hygiene by isolating them from the oral cavity. With the development of the implant, prosthetics on implants overdentures are becoming more and more popular.

In addition to implants on implants or overdentures, it is also necessary to keep the tooth under the mucous membranes, as well as the use of magnets. For many years, removable implants have been used in the treatment of pain in the mouth, especially in the jaw, with promising results. The literature suggests that an IOD should be the first treatment for a dull jaw. This is a profitable option, but at the same time challenged by the fact that a large number of depressed patients are poor and cannot afford implant treatment.

 

Implant-Supported Overdentures

 

Implant-Supported vs. Implant-Retained

One of the basic key differences between implants supported overdentures and implant-retained are that one is removable and the other one if not. Implant-supported overdentures are a permanent process in which before installing the false teeth support or pillars are added to the jawline so they can support the false teeth. Normally six support are added to the upper gum and eight to the lower. And implant-retained is a process in which you can remove your false teeth after the surgery. Implant retained are more common as compare to implant-supported overdentures.

Types of Implant-Supported Overdentures

There are many different types of implant-supported overdentures. Well, the goal of all these types is the same but the difference in the way of implementation implant supports overdentures. Here are some of the common types of implant supports overdentures.

 

Type 1 

This removable denture uses a combination of implant and soft tissue support and is usually more effective in the lower jaw than in the upper jaw. Two implants are commonly used on canines. A prosthesis was implanted. Self-supporting clasps can be rigid to support the implant and soft tissue to support soft tissue up to 0. 6 mm thick to protect the implants from overload.

Type 2 

This removable prosthesis uses a simple round rod that connects two or more implants or a curved rod that holds two or more implants with two distal pivot connectors. The prosthesis is implanted and rests on soft tissues and implants or, depending on the choice of implant fastening, on soft tissues. A characteristic feature of the prosthesis is that the prosthesis is held on a round or oval beam, which allows it to be rotated. Four implants can be used in this scenario.

Type 3

This denture support is similar to the Type 2 treatment planning option. However, if four implants are installed in and around the canine, the anterior pivot clamp and distal ball or other pivot connectors will work. together to reduce the clamping force around the implants.

With four implants, the midline clamp acts as an intermediate stop to prevent the posterior base of the external fixation teeth from rotating away from the posterior ridge of the alveolar tooth during surgery. Another advantage of the centerline clip is that it provides a tripod effect, which is the third reference point for defining the shot. By balancing the area supported by the mucosa and the area supported by the nail implants, rotation of the prosthesis can be reduced.

The center clamp should only ensure accurate alignment when the dentures are in place in the case of type 3, it acts as an intermediate stop, which is essentially a vertical stop for the partially removable prosthetic framework so that the stool at the free end does not protrude from the tissue.

Type 4 

Type 1, and 3 supra prostheses partially support soft tissue areas. A special feature of the type 4 orbit is that the prosthesis is fully supported by rods and implants. The base of hybrid prostheses may contact mucous tissue, but any support is unintentional. Since this prosthesis is fully supported by implants, the same number of implants is required to support fixed prostheses.

Type 1, type 2, and type 3 variants are usually designed to treat lower arch, and type 4 is often used for top pivoting. There are at least five implants in the lower jaw and six in the upper jaw. It all depends on many factors, and many professionals choose six implants in the lower jaw and eight in the upper jaw so that the implants are not overloaded.
