Coronectomy represents a common procedure performed in oral surgery, mostly involving the lower wisdom teeth when the extraction presents a risk of injury to the inferior alveolar nerve (NAI). The surgical approach can be described as a coronal separation of the tooth and leaving the roots intact in the socket. The result is impressive with the disappearance of the symptomatology at first and especially the root migration, which occurs most frequently in the first 6 months.
We present a series of clinical cases of coronectomy involving the lower wisdom tooth which was performed by respecting the preoperative, perioperative, and postoperative measures and whose indications were established correctly.
Besides the previously mentioned indication, this procedure can be associated with other clinical situations such as dentigerous cysts. However, there are several circumstances in which coronectomy is contraindicated. According to our study, we can conclude that coronectomy of mandibular wisdom teeth represents a reassuring alternative to the preservation of NAI. Complications may occur but follow-up remains a key point in visualizing the progression of the roots away from the mandibular canal.
牙冠切除术是口腔外科中一项常见的手术，主要用于下颌智齿拔除存在损伤下牙槽神经（IAN）风险的情况。手术方法可描述为将牙齿进行冠部离断，使牙根完整保留在牙槽窝内。最初症状消失，尤其是牙根移位情况（最常发生在最初6个月），结果令人印象深刻。
我们呈现了一系列下颌智齿牙冠切除术的临床病例，这些手术在遵循术前、术中和术后措施的情况下进行，且适应证确定正确。
除了上述适应证外，该手术还可能与其他临床情况相关，如含牙囊肿。然而，在几种情况下牙冠切除术是禁忌的。根据我们的研究，我们可以得出结论，下颌智齿牙冠切除术是保护下牙槽神经的一种可靠替代方法。可能会发生并发症，但随访仍是观察牙根远离下颌管进展情况的关键。
