【摘要】：目的:研究雙頜墊和肌激動(dòng)器功能矯治器矯治安氏Ⅱ類錯(cuò)頜畸形患者后對(duì)上下頜骨和軟組織的變化方法:選擇22例安氏Ⅱ類錯(cuò)頜患者,隨機(jī)分為雙頜墊治療組和肌激動(dòng)器治療組。雙頜墊治療組女性6例,男性5例;肌激動(dòng)器治療組女性5例,男性6例。雙頜墊功能矯治器治療組平均治療時(shí)間約為9個(gè)月,肌激動(dòng)器功能矯治器平均治療時(shí)間為10個(gè)月,治療結(jié)束后測(cè)量治療前后頭顱側(cè)位片并對(duì)測(cè)量結(jié)果進(jìn)行統(tǒng)計(jì)學(xué)分析。結(jié)果:雙頜墊和肌激動(dòng)器治療后SNA和HI(全面高比指數(shù))減少,差異均沒(méi)有統(tǒng)計(jì)學(xué)意義(P0.05);SNB,ANB,IMPA,Z角,UPPER-LIP(上唇厚度),TOTAL-CHIN(全頦厚),Ao-Bo減少,差異有統(tǒng)計(jì)學(xué)意義(P0.05);FMIA,FMA,OCC-OLANE(咬合平面角),PFH,AFH增大,差異有統(tǒng)計(jì)學(xué)意義(P0.05);兩個(gè)治療組相比較,雙頜墊治療組SNA大于肌激動(dòng)器治療組,HI大于雙頜墊治療組,差異均沒(méi)有統(tǒng)計(jì)學(xué)意義(P0.05);SNB,ANB,FMA,OCC-PLANE,TOTAL-CHIN,PFH,AFH,AO-BO大于肌激動(dòng)器治療組,FMIA,IMPA,Z-ANGLE,UPPER-LIP大于雙頜墊治療組,差異都有統(tǒng)計(jì)學(xué)意義(P0.05)結(jié)論:雙頜墊及肌激動(dòng)器功能矯治器對(duì)生長(zhǎng)發(fā)育期的安氏Ⅱ類錯(cuò)頜畸形患者有明顯的治療作用。雙頜墊和肌激動(dòng)器功能矯治器對(duì)上下頜骨有明顯的治療作用,但雙頜墊功能矯治器的作用明顯于肌激動(dòng)器,雙頜墊及激動(dòng)器功能矯治器對(duì)軟組織的作用效果相似。
[Abstract]:Objective: to study the changes of maxillary bone and soft tissue in patients with Class II malocclusion treated with bimaxillary pad and muscle activator. They were randomly divided into two-jaw pad treatment group and muscle activator treatment group. In the treatment group, 6 cases were female, 5 cases were male, 5 cases were female and 6 cases were male. The average treatment time was about 9 months in the bimaxillary pad functional appliance group and 10 months in the muscle activator appliance. After the treatment, the cranial lateral radiographs were measured before and after treatment and the results were statistically analyzed. Results: after the treatment of bimaxillary pad and muscle exciter, SNA and HIH (total high ratio index) decreased, but the difference was not statistically significant (P 0.05). There was no significant difference in UPPER-LIP (total chin thickness) and Ao-Bo (total chin thickness). The difference was significant (P 0.05). The difference between the two groups was statistically significant (P 0.05), the SNA of the treatment group was greater than that of the group treated with muscle activator, and the difference was not statistically significant (P 0.05). The difference between the two groups was not statistically significant. The difference between the two groups was greater than that in the group treated with muscular activator. The difference was larger than that in the group treated with muscular activator, and the difference was higher than that in the group treated with double maxillary pad, and the difference was not statistically significant between the two groups. The difference between the two groups was higher than that in the group treated with muscular activator, and the difference between the two groups was not statistically significant. The difference was statistically significant (P 0.05). Conclusion: the bimaxillary pad and the functional appliance of muscle activator have obvious therapeutic effect on the patients with Class II malocclusion during growth and development. The effect of bimaxillary pad and muscle activator on the treatment of maxillary and mandibular bone was obvious, but the effect of bimaxillary pad was more obvious than that of muscle activator. The effect of bimaxillary pad and motor appliance on soft tissue was similar.
