IMPACTED TEETH, CREST, COMPLICATIONS
Third molars (M3s) account for about 98% of all impacted teeth. The evolutionary question is whether human jaw size has decreased below a threshold such that our M3s lack space to develop [In order to promote better periodontal healing of the distal aspect of the M2, the osteotomy should not be too close to the M2. Care should be taken to avoid iatrogenic injuries to the alveolar crest of the adjacent M2. In this context, the surgical exposure of the root of the IMTM may be better than the crown. Therefore, the removal of the roots would be relatively easier as the resistance has been eliminated, and the friction between the roots and the inferior alveolar nerve may be reduced indirectly. Hence, we named it, explicitly, the “Root Removal First” Strategy. To investigate the clinical outcomes of this strategy, we compared this innovative method to the traditional “Crown Removal First” strategy. And it was shown to reduce the complications such as inferior alveolar nerve injury and extraction-related periodontal problems of M2.
