Implant supported removable denture
Implant-assisted removable partial dentures (IRPD) involve a few strategically placed implants which are spread across the area of missing teeth. The strategic placement will help with support which should take the load off the existing teeth. These implants are connected to the denture using a small screw or stud. This type of implant is more aesthetically pleasing as it reduces the visibility of metal components, such as metal clasps. Support, strength and durability are all increased with this type of procedure.
An IRPD can be structurally changed to include teeth that could potentially be removed in the future. When the initial implants have stabilised, abutments will be connected to the implants allowing for the denture to be attached. The abutments can be individual stud attachments or part of a larger structure with many clip attachments. The artificial prosthesis is made according to the individual’s tooth impressions and attached as above. The implant must be checked over at regular intervals depending on the state of the remaining natural teeth. This oral structure can eventually experience wear and tear, so it will require replacement eventually. Dentures typically last for many years but the retentive aspects and structural components will need evaluating by a dentist every six months or as advised.
What is an Implant Overdenture?
An implant overdenture offers stability and preservation of a complete denture set. This device fits over a dental implant and features many different attachments. This procedure is used to replace a full set of missing teeth with a full-arch. This is essentially a bigger adaptation of the implant assisted removable partial denture (IRPD). The implant overdenture easily clicks into place which allows comfort and ease of wearing. Chewing is improved greatly as these implant overdentures are held in place with a range of attachments personally selected by the dentist. These attachments are designed to provide ultimate retention. Maintaining oral hygiene is easy with the implant overdenture as it is easily removed. This structure looks and feels very natural.
The preparation for implant overdentures involves gum and jaw impressions to gauge the size and structure of the dentures. The positioning of the teeth on the denture structure will be considered along with the prime position for each dental implant. The appearance and bite will be taken into account. Normally, a prototype will be produced first to act as a template so that the surgeon can use it as guidance when completing the procedure.
An upper implant overdenture will need more implants than a lower implant overdenture due to the variable aspects of the upper and lower jaws. An upper overdenture may be made without the need for a palate (roof of the mouth) to assist with comfort.
There are many specific needs for an implant overdenture procedure which can vary with importance. The decision for this treatment must be considered with a dentist and alternative options should be researched. Many patients will benefit from the support this treatment can provide including facial support provided by the extensions of the overdenture structure. The number of implants required should be decided by the dentist, whilst taking into account personal factors and experiences with any current dentures used.
