The removal of all teeth, and the simultaneous placement of dentures, is called a full dentectomy. This procedure is in most cases, performed under general anesthetic.
When planning a dentectomy, the dentist will discuss all options available to avoid doing a
dentectomy. The financial implications to restore all the remaining teeth might be too high, or the remaining teeth might be in too an advance state of decay to restore them. In these situations the option of a dentectomy and the placement of implants might be the only practical solution.
Once the teeth are removed, bone loss will start. The dento- alveolar bone ( this is the bone supporting the teeth), will rapidly fall away, and it is recognized that all the dento – alveolar bone will be gone in 10 to 15 years after a dentectomy, if implants were not placed. This will result in the lower denture floating on the lower jaw (loose), or in the case of the upper jaw, falling out during speech or chewing. This is why having a dentectomy, can be life changing with detrimental effects on your general health in the long run.
It is universally accepted today, that after a dentectomy, the patient’s jaws will need to be
reconstructed with implant placements afterwards.
Implant placement in the jaw, has the additional benefit, on top of fixation of the denture or bridge in the mouth, to stop the dento – alveolar bone from falling away. The bone is therefore preserved in the long run.
When receiving a dentectomy, or single tooth /residual root removal, planning should already be done to restore the missing teeth / tooth with an implant.
Prior to the dentectomy, the dentist will manufacture an immediate denture for placement immediately after the procedure. Relining and relieving of the denture will be necessary within a week after the dentectomy. This immediate denture will have to be replaced with a new denture after 1 year. If implants are to be placed at the same time as the dentectomy, thorough planning will be done prior to the procedure.
