Socket preservation or alveolar ridge preservation is a procedure to reduce bone loss after tooth extraction. [1] [2] After tooth extraction, the jaw bone has a natural tendency to become narrow, and lose its original shape because the bone quickly resorbs, resulting in 30–60% loss in bone volume in the first six months. [3]
The most common location of dry socket: in the socket of an extracted mandibular third molar (wisdom tooth). Since alveolar osteitis is not primarily an infection, there is not usually any pyrexia (fever) or cervical lymphadenitis (swollen glands in the neck), and only minimal edema (swelling) and erythema (redness) is present in the soft tissues surrounding the socket.
This is usually the choice taken if the reason of dental extraction is due to impacted wisdom teeth or orthodontics because of limited space. The alveolar bone will slowly resorb over time once the tooth is lost. Potential esthetic concern. Potential for drifting and rotation of adjacent teeth into the gap over time.
A study used e-PTFE membranes to cover surgically constructed average size bone defects in the mandibular angles of rats. Consequently, the e-PTFE membrane acted as a barrier to soft tissue and sped up bone healing, which took place between 3–6 weeks while no healing occurred in the non-membrane control group during a 22 week period.

Tooth #5, the upper right second premolar, after extraction. The two single-headed arrows point to the CEJ, which is the line separating the crown (in this case, heavily decayed) and the roots. The double headed arrow (bottom right) shows the extent of the abscess that surrounds the apex of the palatal root.
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.
An oroantral fistula (OAF) is an epithelialized oroantral communication (OAC), which refers to an abnormal connection between the oral cavity and the antrum. [1] The creation of an OAC is most commonly due to the extraction of a maxillary tooth (typically a maxillary first molar) which is closely related to the antral floor.
Patients undergoing coronectomy are anticipated to experience easier recovery from IAN deficits compared to those undergoing extractions. Limited studies indicate a 100% recovery rate in coronectomy patients, whereas only 66% of patients undergoing extraction recover within one month. 62.2% of the roots will migrate post-coronectomy, erupting ...
