1、正颌骨头薄能磨骨吗
取决于骨头薄的程度。
骨头薄程度较轻
骨头厚度在46毫米范围内时，通常可以磨骨。
经验丰富的正颌外科医生可以通过精细技术安全地磨除骨头，不会影响强度。
骨头薄程度较重
骨头厚度低于4毫米时，磨骨可能会存在风险。
过度磨骨会导致骨骼变弱、骨折或神经损伤。在这种情况下，可能有必要进行骨移植或其他手术来加强骨骼。
具体评估
建议与有经验的正颌外科医生进行咨询，以对骨头薄度进行适当评估。医生会考虑以下因素：
骨头厚度和密度
下颌骨的整体健康状况
手术目标和计划
替代方案
如果骨头太薄而不能磨骨，可能还有其他替代方案可供考虑，例如：
削骨术：去除下颌骨的一部分，而不是磨骨。
正颌外科：移动下颌骨，而不是磨骨。
颏部假体：插入假体来增强下颌骨的外观。
2、磨骨和削骨哪一个风险小
削骨风险较小。
磨骨和削骨的区别
磨骨：利用机器将骨头表面打磨，变薄变平，达到瘦脸效果。
削骨：通过手术切除部分骨头，直接改变骨骼形状，并达到瘦脸效果。
风险对比
创伤性：削骨的手术创伤更大，需要切开皮肤和骨膜。而磨骨创伤较小，只需要在骨头上打磨。
神经损伤：削骨手术可能损伤神经，导致面部麻木或表情异常。而磨骨不会损伤神经。
出血：削骨手术可能出血更多。
感染：削骨手术的感染风险更高。
二次手术：削骨手术后可能会出现骨头再生的情况，需要二次手术。而磨骨不会出现这种情况。
因此，削骨的风险通常大于磨骨。具体风险大小还取决于患者的具体情况，需要咨询专业医生进行评估。

Under the terms of the agreement, USANA will pay Healthquest an upfront payment of $15.0 million in cash and will make milestone payments of up to $10.0 million in cash, subject to the achievement of certain regulatory and commercial milestones. USANA will also pay Healthquest royalties on net sales of products containing CGM.
The acquisition of the CGM technology is expected to accelerate USANA’s entry into the global nail care market, which is estimated to be worth over $10 billion. USANA plans to develop and market a line of OTC and prescription nail care products based on the CGM technology, including products for the treatment of onychomycosis, a common fungal infection of the nails.
“The acquisition of Healthquest’s CGM technology is a significant milestone for USANA,” said Kevin Guest, USANA’s Chairman and CEO. “This technology has the potential to revolutionize the treatment of nail conditions, and we believe that it will allow us to develop a line of innovative and effective products that will meet the needs of consumers around the world.”
“We are excited to partner with USANA to bring our CGM technology to market,” said James E. Voss, Healthquest’s President and CEO. “USANA has a proven track record of developing and marketing innovative health and beauty products, and we believe that they are the ideal partner to help us realize the full potential of our technology.”
The transaction is expected to close in the fourth quarter of 2023, subject to customary closing conditions.

4、正颌手术对脸型影响
正颌手术对脸型的影响
正颌手术是一种外科手术，旨在纠正颌面部的结构异常。它可以通过改善牙齿咬合、呼吸和面部美观来产生显著的影响。
对脸型的影响
正颌手术对脸型的影响因个体情况而异，但常见的影响包括：
改善整体平衡和对称性：手术可以通过移动上下颌骨，来纠正面部不对称或下颌后退等问题。
改善咬合：通过重新排列颌骨，正颌手术可以改善牙齿咬合，从而减轻颞下颌关节 (TMJ) 疼痛或其他咬合问题。
改善呼吸：如果颌骨异常导致呼吸道狭窄，正颌手术可以扩大气道，从而改善呼吸。
增强面部美观：通过移动颌骨，手术可以显着改变面部轮廓，塑造更和谐的面部特征。这可能包括：
改善下巴线和下颌轮廓
减少双下巴
改善鼻唇角
改善笑线
改善面部功能：除了美学益处外，正颌手术还可以改善面部功能，例如：
改善咀嚼能力
改善言语清晰度
减少打鼾或睡眠呼吸暂停
时间表
正颌手术的效果通常在手术后立即显现，但在肿胀消退和骨骼愈合过程中，最终结果可能需要数月才能显现。
风险和并发症
与任何手术一样，正颌手术也存在一定的风险和并发症，但这些风险通常很小。潜在的并发症包括：
感染
出血
神经损伤
颞下颌关节疼痛
麻木或感觉异常
复发
对手术结果不满意
结论
正颌手术对脸型有重大影响，可以改善面部平衡、咬合、呼吸和美观。重要的是与合格的外科医生讨论手术的潜在益处和风险，以确定它是否适合您。
