Oral and Maxillofacial SurgeryAn intraoral periapical x-ray is the primary diagnostic tool for
detecting impacted molars. This type of x-ray provides a detailed view of the
entire tooth, including the surrounding bone and tissues, allowing the dentist
to determine the position and angulation of the impacted tooth in relation to
the adjacent structures. However, a CBCT may be used in more complex cases for a
three-dimensional assessment.

Oral and Maxillofacial SurgeryThe lingual split technique minimizes bone loss and tissue trauma by dividing the tooth along its longitudinal axis and removing it in two halves, reducing the need for extensive buccal bone removal.
544668
Oral and Maxillofacial SurgeryA bull's eye appearance on an IOPA film suggests that the tooth is
lingually placed with its occlusal surface facing the tongue, which is
characteristic of a lingual impaction of a mandibular third molar.
890606
Oral and Maxillofacial SurgeryMesioangular impactions are the most common and typically involve
the tooth being angulated towards the mesial surface of the adjacent second
molar. This orientation allows for a more straightforward surgical approach
compared to other impaction types.

Oral and Maxillofacial SurgeryPolydioxanone (PDS) is designed to retain a significant amount of its tensile strength for an extended period, making it ideal for situations where prolonged wound support is necessary.
488173
Oral and Maxillofacial SurgeryDentists determine the position of an impacted tooth using an x-ray by evaluating its relationship with the nerve, the adjacent teeth, and other anatomical structures such as the maxillary sinus or the mandibular canal. This helps in planning the surgical approach for extraction and predicting potential complications.
868760
Oral and Maxillofacial SurgeryDistoangular impactions involve a complex surgical approach that
often requires significant bone removal to extract the tooth safely without
damaging adjacent structures. The position of the tooth in relation to the ramus
of the mandible and the potential for weakening the bone structure make it a
challenging procedure.

Oral and Maxillofacial SurgeryMultifilament sutures, such as Vicryl, have a braided structure that can trap bacteria, leading to a higher potential for infection compared to monofilament sutures.
