After tooth extraction, the alveolar ridge has a mean loss of width of 3.8 mm, and a height loss of 1.24 mm within six months. [1] This loss of bone volume, can cause a denture to be loose, or an inadequate amount of bone width to place an implant. [5] Historically, alveolar preservation was used to provide a base to retain conventional dentures.
At the time of extraction or after healing and bone remodeling has happened, alveolar bone irregularities may be found. The goal for alveoloplasty [ 8 ] is to achieve optimal tissue support for the planned prosthesis, while preserving as much bone and soft tissue as possible.
Prolonged bleeding: The dentist has a variety of means at his/her disposal to address bleeding; however, small amounts of blood mixed in the saliva after extraction are normal, even up to 72 hours after extraction. Usually, however, bleeding will almost completely stop within eight hours of the surgery, with only minuscule amounts of blood ...
The prerequisites for long-term success of osseointegrated dental implants are healthy bone and gingiva. Since both can atrophy after tooth extraction, pre-prosthetic procedures such as sinus lifts or gingival grafts are sometimes required to recreate ideal bone and gingiva.
RAIs are custom made to perfectly fit the tooth socket of a specific patient immediately after tooth extraction. Therefore every implant is unique. As an optimised root-form it is much more than a simple 1:1 replica of a tooth. Since it exactly fills the gap left after the tooth is extracted, surgery is rarely needed.
Delayed replantation has a poor long term prognosis due to the death of the periodontal ligament, [14] increasing the likelihood of complications such as ankylosis, infection and pulp necrosis. Avulsed teeth should be replanted within the hour to increase the likelihood of a successful tooth replantation.
Dentures can help people via: Mastication: chewing ability is improved by the replacement of edentulous (lacking teeth) areas with denture teeth.; Aesthetics: the presence of teeth gives a natural appearance to the face, and wearing a denture to replace missing teeth provides support for the lips and cheeks and corrects the collapsed appearance that results from the loss of teeth.
Dental disease and extractions; patients with poor oral hygiene and dental disease prior to radiation, including edentulous patients and those with dentures, are more susceptible to developing ORN. [ 3 ] [ 9 ] Diseased teeth near the radiation field may need to be extracted, [ 23 ] and should be evaluated prior to radiation treatment.
