increase the morbidity above what would be
expected from a particular operative procedure
under normal circumstances.

Soft Tissue Injuries
7. ο
1. Tear of a Mucosal Flap
The most common soft tissue injury is the tearing of the mucosal
flap during surgical extraction of a tooth. This is usually-the
result of an inadequately sized envelope flap, which is retracted
beyond the tissueβs ability to stretch.
8. ο
2. Puncture Wound
Using uncontrolled force during using the Instruments such as
straight elevator or a periosteal elevator which may slip from the
surgical field and puncture or tear the adjacent soft tissue.
9. ο
3. Stretch or Abrasion
Occur when bur come in contact with soft tissue such as lip
corner of the mouth during dental extraction.
11. ο
1. Root Fracture
Root fracture can occur during extraction of teeth. The clinician
must then decide to either leave the root fragment or not.
12. ο
2. Root Displacement
Roots can occasionally be displaced into the maxillary sinus,
submandibular, infratemporal space.
13. ο
1. Fracture or Dislodgement of an Adjacent Restoration
2. Luxation of an Adjacent Tooth
3. Extraction of Wrong Tooth
Injuries to Adjacent
Teeth
14. ο
1. Fracture or Dislodgement of an Adjacent
Restoration
The fillings or crowns of the adjacent teeth may come out during
the tooth extraction procedure. It can occur due to injudicious
use of elevators during the tooth extraction.
15. ο
2. Luxation of an Adjacent Tooth
The adjacent teeth may become loose or fracture during the tooth
extraction procedure.
16. ο
3. Extraction of Wrong Tooth
Extraction of wrong tooth is done due to improper diagnosis.
17. ο
1. Fracture of the Alveolar Process
2. Fracture of the Maxillary Tuberosity
Injuries to Osseous
Structures
18. ο
1. Fracture of the Alveolar Process
Alveolar process fractures are fractures of the tooth-bearing part
of the jaw it is most commonly due to excessive force from the
forceps.
19. ο
2. Fracture of the Maxillary Tuberosity
Occasionally, during the course of maxillary molar extraction, the
maxillary tuberosity may be fractured and may seem to be
loosening when grasped by the forceps.
20. ο
1. Injury to Regional Nerves
2. Injury to the Temporomandibular Joint
Injuries to Adjacent
Structures
21. ο
1. Injury to Regional Nerves
During surgical extraction, each of these nerves are at risk of
damage, but the most complication result from Inferior Alveolar
or Lingual Nerve injury to the lingual nerve may happen during
3rd molar surgery due to the anatomical proximity of the cortex
region of the molar.
22. ο
2. Injury to the Temporomandibular Joint
During extraction, the heavy force applied by elevators or
forceps can cause injury to TMJ.
23. ο
Oro-antral Communication is an abnormal communication
between the maxillary sinus and the oral cavity.
Oroantral
Communications
24. ο
ο Prevention of complication should be major goal of
the surgeon.
ο Complication should be diagnosed as soon as they
occur and dealt promptly and effectively.
ο The surgeon who anticipates a reasonable
probability of an unusual specific complication
should inform the patient.
