The occurrence of an orofacial trauma can originate health, social, economic and professional problems. A 13-year boy suffered the avulsion of tooth 11 and 21, lost at the scenario.
Three intraoral appliances were manufactured: A Hawley appliance with a central expansion screw and two central incisors (1), trumpet edentulous anterior tooth appliance (2) and a customized splint (3) were designed as part of the rehabilitation procedure. Objectively assessing the sound quality of the trumpet player with these new devices in terms of its spectral, temporal, and spectro-temporal audio properties. A linear frequency response microphone was adopted for precision measurement of pitch, loudness, and timbre descriptors.
Pitch deviations may result from the different intra-oral appliances due to the alteration of the mouth cavity, respectively, the area occupied and modification/interaction with the anatomy. This investigation supports the findings that the intra-oral appliance which occupies less volume is the best solution in terms of sound quality.
Young wind instrumentalists should have dental impressions of their teeth made, so their dentist has the most reliable anatomy of the natural teeth in case of an orofacial trauma. Likewise, the registration of their sound quality should be done regularly to have standard parameters for comparison.
口腔颌面部创伤的发生可导致健康、社会、经济和职业问题。一名 13 岁男孩在现场遭受了 11 号和 21 号牙的脱位。
制作了三种口腔内装置:带有中央扩张螺丝和两颗中切牙的 Hawley 矫治器(1)、喇叭状无牙前牙矫治器(2)和定制夹板(3),作为康复程序的一部分。客观评估这些新设备的喇叭吹奏者的音质,包括其频谱、时域和谱时音频特性。采用线性频率响应麦克风对音高、响度和音色描述符进行精确测量。
由于口腔的改变,分别占据不同的口腔内装置可能导致音高偏差,以及所占据的区域和与解剖结构的修改/相互作用。这项研究支持以下发现,即就音质而言,占据较少体积的口腔内装置是最佳解决方案。
年轻的管乐器演奏者应该进行牙齿印模,以便牙医在发生口腔颌面部创伤时拥有最可靠的天然牙齿解剖结构。同样,应该定期记录他们的音质,以便有标准参数进行比较。
