The buccal bone plate is a component of the alveolar process tightly related to the tooth it supports. A plethora of physiological and pathological events can induce its remodeling. Understanding this remodeling process and its extent is of major importance for the practitioner as it can affect the functional and esthetic outcome of implant surgery at the involved sites. Bone remodeling and resorption of the buccal bone plate are inevitable after tooth loss or extraction. To limit resorption, several ridge-preservation techniques of varying efficacy have been described. Bone resorption is equally found to occur upon implant placement and is thought to be a result of the surgical trauma inflicted as well as an adaptation process of the tissues to the new foreign body. Because of the implications of bone resorption on the soft-tissue levels and the general esthetic outcome, it is of primary importance for the practitioner to be able to evaluate the hard tissues and the inherent resorption risks in an effort to optimize the treatment strategies. Based on limited short-term data, the present general opinion advises the need for a 2-mm-thick buccal bone plate in order to avoid vertical bone resorption.
颊骨板是牙槽突的一个组成部分，与它所支持的牙齿紧密相关。大量的生理和病理事件会引起其重塑。了解这种重塑过程及其程度对医生来说非常重要，因为它会影响相关部位种植手术的功能和美观效果。牙齿缺失或拔除后，颊骨板的骨重塑和吸收是不可避免的。为了限制吸收，已经描述了多种不同效果的牙槽嵴保存技术。在种植体植入时同样会发生骨吸收，这被认为是手术创伤以及组织对异物的适应过程的结果。由于骨吸收对软组织水平和整体美观效果的影响，医生有必要能够评估硬组织和潜在的吸收风险，以优化治疗策略。根据有限的短期数据，目前的普遍观点建议需要 2 毫米厚的颊骨板，以避免垂直骨吸收。
