At times dental crowding, maxillary arch inadequacy, or an abnormal lingual or horizontal position restricts the eruption of the maxillary cuspid. This ectopic eruption can cause the canine to compress the blood supply to the periodontal tissues of the adjacent lateral incisor. If undiagnosed and untreated, physiological and chemical changes are induced, and the lateral root undergoes resorption. When the resorption is severe enough to endanger the retention of the lateral, an endeosseous stabilizer can be placed through the root and extended into the bone to stabilize the tooth artificially. Two cases demonstrate the technique and success of such treatment.
有时，牙列拥挤、上颌牙弓不足或异常的舌侧或水平位置会限制上颌尖牙的萌出。这种异位萌出会导致尖牙压迫相邻侧切牙牙周组织的血液供应。如果未被诊断和治疗，会引发生理和化学变化，侧切牙根会发生吸收。当吸收严重到足以危及侧切牙的固位时，可以通过牙根放置骨内稳定器并延伸至骨内，以人工方式稳定牙齿。两个病例展示了这种治疗方法及其成功之处。
