Question 306 · LDEK · Impacted teeth
Class B of the Tetsch and Wagner classification refers to:
- A. horizontal impaction - the tooth is aligned parallel to the occlusal plane, at an angle of approximately 90° to the adjacent teeth.
- B. occlusal surface of the impacted tooth is between the occlusal surface and the neck of the adjacent tooth.
- C. minor bone tissue loss (the distance between the bone margin and the gingival line is 3-5 mm) - immediate implantation possible.
- D. loss of 1-3 mm of the buccal plate.
- E. advanced cavity - adequate amount of bone tissue but of poor quality or insufficient amount of bone tissue.
Hint
Classes A, B and C in this scheme describe how deep the impacted tooth lies relative to the adjacent tooth.
