【摘要】：目的:對(duì)云南地區(qū)人群進(jìn)行三維頭影測(cè)量分析,為牙頜面畸形及顳下頜關(guān)節(jié)病患者的診治提供參考依據(jù)。材料與方法:研究一:選取到昆明醫(yī)科大學(xué)附屬口腔醫(yī)院就診的云南地區(qū)患者共727例,其中男性365例,女性362例,年齡11～65歲,平均29. 5歲。以年齡分為3組。利用SimPlant 11.04軟件進(jìn)行三維頭影測(cè)量分析,以顱頜面硬組織相關(guān)24個(gè)標(biāo)志點(diǎn)進(jìn)行定點(diǎn),并對(duì)測(cè)量結(jié)果進(jìn)行比較分析。研究二:選昆明醫(yī)科大學(xué)附屬口腔醫(yī)院口腔頜面外科診治的4例牙頜面畸形、10例顳下頜關(guān)節(jié)強(qiáng)直及6例單純喙突增生(無(wú)顳下頜關(guān)節(jié)器質(zhì)性病變)患者,進(jìn)行三維頭影測(cè)量分析。對(duì)4例牙頜面畸形患者行正頜外科手術(shù),10例顳下頜關(guān)節(jié)強(qiáng)直患者行顳下頜關(guān)節(jié)成型術(shù)加喙突切除術(shù),6例喙突增生患者行喙突切除術(shù),并對(duì)術(shù)后的開(kāi)口度進(jìn)行統(tǒng)計(jì)分析。結(jié)果:1.骨組織角度及牙槽角度、線距及面寬、下頜骨寬及顴骨寬在CBCT-3D與CBCT-2D中比較具有顯著性差異(P0.05)。面寬、下頜骨寬及顴骨寬在CBCT-3D中性別具有顯著性差異(P0.05)。成年中男性與女性的面下部高度(ANS-Me)具有顯著性差異(P0.05)。2.4例牙頜面畸形患者順利完成正頜外科手術(shù),術(shù)后患者達(dá)到較好的美學(xué)效果與良好的咬合關(guān)系,治療效果滿意。10例顳下頜關(guān)節(jié)強(qiáng)直及6例喙突增生患者手術(shù)后張口度均得到明顯改善。結(jié)論:1.CBCT-3D與CBCT-2D測(cè)量結(jié)果存在一定的差異,CBCT-3D數(shù)據(jù)相對(duì)較為可靠。并且,成年男性面下部高度大于女性。正常人群中男性的顴骨、下頜骨、面寬較女性明顯�；贑BCT三維頭影測(cè)量值可以為臨床提供參考依據(jù)。2.牙頜面畸形患者經(jīng)過(guò)正頜外科手術(shù)治療,外貌及口頜功能均得到明顯改善,治療效果確切,顱頜面硬組織數(shù)據(jù)具有較好的參考價(jià)值,具有有效的可靠性。此外,建立喙突長(zhǎng)度標(biāo)準(zhǔn)值可為喙突增生的患者提供參考及臨床應(yīng)用價(jià)值。
[Abstract]:Objective: to provide a reference for the diagnosis and treatment of odontomaxillofacial malformation and temporomandibular arthropathy. Materials and methods: 1. A total of 727 patients in Yunnan Province were selected from the affiliated Stomatological Hospital of Kunming Medical University, 365 males and 362 females, aged 1165 years, with an average of 29.9 years. Five years old. They were divided into 3 groups according to their age. Three-dimensional cephalometric analysis was carried out with SimPlant 11.04 software, and 24 markers of craniomaxillofacial hard tissue were used for fixed points, and the results were compared and analyzed. Study 2: four patients with maxillofacial malformation, 10 patients with temporomandibular joint ankylosis and 6 patients with simple coracoid process hyperplasia (without temporomandibular joint organic lesion) were selected from oral and maxillofacial surgery, affiliated to Kunming Medical University. 3 D cephalometric analysis. Four patients with maxillofacial malformation were treated with orthognathic surgery and 10 patients with temporomandibular joint ankylosis underwent temporomandibular arthroplasty plus coracoid process resection. Coracoid process resection was performed in 6 patients with coracoid process hyperplasia. The result is 1: 1. There were significant differences in bone tissue angle, alveolar angle, line distance and facial width, mandibular width and zygomatic width between CBCT-3D and CBCT-2D. There were significant differences in facial width, mandibular width and zygomatic width in CBCT-3D. There was significant difference between male and female in lower facial height (ANS-Me). The orthognathic surgery was successfully completed in 2.4 patients with dental and maxillofacial malformation. The results were satisfactory. 10 cases of temporomandibular joint ankylosis and 6 cases of coracoid process hyperplasia were obviously improved after operation. Conclusion 1. There is a certain difference between CBCT-3D and CBCT-2D measurement results. CBCT-3D data are relatively reliable. Moreover, the lower face height of adult males was higher than that of females. The zygomatic bone, mandible and facial width of the male were significantly larger than that of the female in the normal population. The three-dimensional cephalometric value based on CBCT can provide reference basis for clinical. 2. 2. After orthognathic surgery, the appearance and oral and maxillary function of the patients with maxillofacial malformation were obviously improved. The data of craniomaxillofacial hard tissue had good reference value and effective reliability. In addition, establishing the standard value of coracoid process length can provide reference and clinical application value for patients with coracoid process hyperplasia.
