“… 2 3 10 Although iatrogenic tooth displacement was found to be rare during the extraction of maxillary third molars, maxillary third molars have been accidentally displaced into adjacent anatomic spaces. 2 Depending on the direction of force application, the maxillary third molar can be displaced superiorly to the maxillary sinus, 11 posteriorly to the infratemporal fossa, 3 4 10 posterolaterally to the buccal space, 12 posterosuperiorly to the pterygopalatine space, 13 or posteromedially into the lateral pharyngeal space. 14 Inadequate bone height buccal and distal to the molar has been associated with a higher risk of displacement into the buccal space.…”

PurposeThis study investigated maxillary third molars and their relation to the maxillary sinus using panoramic radiography and cone-beam computed tomography (CBCT).Materials and MethodsA total of 395 maxillary third molars in 234 patients were examined using panoramic radiographs and CBCT images. We examined the eruption level of the maxillary third molars, the available retromolar space, the angulation, the relationship to the second molars, the number of roots, and the relationship between the roots and the sinus.ResultsFemales had a higher frequency of maxillary third molars with occlusal planes apical to the cervical line of the second molar (Level C) than males. All third molars with insufficient retromolar space were Level C. The most common angulation was vertical, followed by buccoangular. Almost all of the Level C molars were in contact with the roots of the second molar. Erupted teeth most commonly had three roots, and completely impacted teeth most commonly had one root. The superimposition of one third of the root and the sinus floor was most commonly associated with the sinus floor being located on the buccal side of the root.ConclusionEruption levels were differently distributed according to gender. A statistically significant association was found between the eruption level and the available retromolar space. When panoramic radiographs showed a superimposition of the roots and the sinus floor, expansion of the sinus to the buccal side of the root was generally observed in CBCT images.

“…Incorrect use of the elevator may lead to a fracture of the buccal bone, which consists mostly of trabecular bone with a thin cortical layer, and push the tooth into the buccal space. The risk increases if the bone height buccal and/or distal to the molar is inadequate [28].…”

“…1 One of the major complications of maxillary third molar removal is the accidental displacement of the tooth into adjacent anatomical spaces such as maxillary sinus, infratemporal fossa, pterygopalatine fosaa, lateral pharyngeal space and buccal space. 1,2 Risk of this complication is increased due to poor visibility of maxillary third molar, poor accessibility to the region and presence of thin maxillary tuberosity. This case report discusses the dislodgement of maxillary third molar into pterygomandibular space (PtMS) during surgical removal, a complication that has not been reported till date.…”

Management of iatrogenic displacement of maxillary third molar into pterygomandibular space: case report

<p>Third molar surgery is the most common minor oral surgical procedure performed in dental clinics. Displacement of maxillary third molar tooth into adjacent spaces such as infratemporal fossa, maxillary sinus has been reported earlier. We present an unusual case of iatrogenic displacement of maxillary third molar into pterygomandibular space. A 24 year old dental undergraduate reported to Department of Oral surgery with complaints of trismus and swelling in the check region after unsuccessful attempt at extraction of maxillary right third molar tooth. Computed tomography scan localized the tooth in the pterygomandibular space. A surgical removal of the displaced tooth was performed under general anesthesia. Displaced tooth was approached by an intraoral vertical incision along the anterior border of ramus of mandible. Correlating with computed tomography scan, tooth was located and removed followed by suturing of the surgical site. A good knowledge of the operating area and adjoining spaces is essential to avoid iatrogenic damage to tissues during minor oral surgery procedures. Adequate exposure and appropriate instrumentation during surgery can prevent undue complications and ensure quality patient care.</p>
