个性化正畸正颌联合治疗唇腭裂继发严重错牙合畸形1例

唇腭裂是口腔颌面部最常见的先天性畸形,患者经历综合序列治疗后出现的不可避免的颌骨发育障碍仍是影响其咀嚼、面型及心理的重要问题.其常表现为面部三维方向的发育不足、上颌后缩及下颌真性前突、因上颌牙弓狭窄致牙列拥挤、咬合关系极度紊乱;与其他牙牙合面畸形相比,该病治疗难度大、术后复发率高,传统单纯牙列正畸矫治难以达到满意的效果...     

19例唇腭裂患者继发牙颌畸形正畸正颌联合治疗的经验

目的：探讨正畸及正颌手术联合治疗唇腭裂术后牙颌面畸形。方法：19例唇腭裂患者，通过术前正畸，并摄X线头颅侧位定位片，用计算机预测正颌术后侧貌，采用上颌Le Fort I型截骨前移术或加双下颌支矢状劈开截骨后退术。结果：治疗后SNA、ANB的角度明显增大（P＜0．001）。结论：唇腭裂患者的术前正畸主要是排齐牙列，直立牙长轴，下前牙的去代偿。唇腭裂术后上颌严重发育不良，由于受上颌周围痕牵拉，前移幅度受限，可采取双颌手术。     

错He畸形正畸治疗后的稳定性研究

目的本研究旨在探讨Ⅰ、Ⅱ类错畸形患者正畸治疗后牙的变化趋势,并探讨影响和预测牙变化的要关因素。以期为临床实践提供参考。方法选取11－18岁之间的安氏Ⅰ,Ⅱ类错畸形患者72例。选择十项模型测量指标对牙变化进行评估。对所得数据采用配对t检验,多因素方差分析,多元相关分析。结果保持后牙关系有向治疗前回复的趋势,但仍旧保持了大部分的治疗效果。各项指标的变化在拔牙与不拔牙之间,安氏Ⅰ,Ⅱ类之间无差别。上尖牙间宽度较下尖牙间宽度更稳定。下尖牙间宽度保持后缩小明显且伴随下前牙拥挤增大。

Prevalence and awareness of malocclusion in Swedish men

Previous orthodontic treatment, the awareness of malocclusion, the demand for orthodontic treatment and the prevalence of malocclusion were studied in 389 Swedish men, aged 21-54 years (mean age 32 years). Nine percent had been treated with an orthodontic appliance and 15% reported that permanent teeth had been extracted on orthodontic indications. Malposition of teeth was found in 75%, with rotation as the most common type of malposition. Crowding was recorded in 43% and spacing in 18%. Fifty-seven percent had some occlusal anomaly. The need for orthodontic treatment was rated on a four-point scale. It was found that 76% were in need of treatment. The need for treatment was only slight in half of the men but moderate to urgent in 25% of the sample. About a quarter of the men were aware of malposition of front teeth, equally often for maxillary and mandibular teeth, but only about 1% were aware of malposition of posterior teeth. Only a few percent thought they were in need of orthodontic treatment. The presence of malocclusion was correlated to age, place of birth and educational level. This might perhaps be a consequence of tooth loss.     

未治疗安氏Ⅰ类错殆软组织特点及其生长发育特点的研究

的：研究未治疗的安氏I类错殆患者软组织特点及其生长发育特点,为l临床上安氏I类错殆的治疗提供参考。方法：收集安氏I类错殆病例909例,按性别和CVM分期分组,通过头颅侧位片测量不同性别,不同颈椎分期患者软组织厚度和方向的改变,SPSS18．0方差分析后进行组间多重对比。结果：男性ULP、LLP、H角、FCA、H线与鼻、鼻唇沟及颏唇沟的距离基本都大于女性。鼻唇角大小正常,但性别差异显著。男女性患者在FCA和H线与鼻、鼻唇沟、颏唇沟的距离生长发育趋势大体相似。H线与鼻部的距离逐渐减小,男性上唇突度在CSl-CS4期逐渐增大,女性在CSl-CS3期逐渐增大,无明显统计学意义,但女性生长发育早于男性。结论：在CSl-CS6期,男性软组织厚度基本大于女性,鼻唇角性别差异较大。男女性别在软组织生长发育方向趋势上大体相似,但女性软组织生长发育早于男性。

Management of the Class III malocclusion treated with maxillary expansion,facemask therapy and corrective orthodontic. A 15-year follow-up

The facial growth of Class III malocclusion worsens with age, in this case, the early orthopedic treatment, providing facial balance, modifying the maxillofacial growth and development. A 7.6-year old boy presented with Class III malocclusion associated with anterior crossbite; the mandible was shifted to the right and the maxilla had a transversal deficiency. Rapid maxillary expansion followed by facemask therapy was performed, to correct the anteroposterior relationship and improve the facial profile. The patient was followed for a 15-year period, after completion of the treatment, and stability was observed. Growing patients should be monitored following their treatment, so as to prevent malocclusion relapse.

Prevalence of malocclusion traits and orthodontic treatment in a Finnish adult population

Objective The aim of the study was to examine the prevalence of malocclusion traits and the extent of orthodontic treatment in a Finnish adult population. Materials and methods The study population comprised subjects (n?=?1964) from the Northern Finland Birth Cohort 1966 living in the city of Oulu and within 100?km of it. A clinical oral and dental examination with registration of occlusion was carried out in 2012 in connection with a 46-year follow-up survey. Data on previous orthodontic treatment were collected based on a questionnaire. Results In the clinical examination, 39.5% of the subjects had at least one malocclusion trait. The most common malocclusion traits were lateral crossbite (17.9%), overbite?≥?6?mm (11.7%) and overjet?≥?6?mm (9.7%). Crossbite on the left premolars, negative overjet and increased overbite were found more frequently in men. The prevalence of malocclusion traits was at the same level in treated and untreated groups. Overall, 18.6% of the subjects had undergone orthodontic treatment. Women showed a significantly higher prevalence of orthodontic treatment. Conclusions The most common malocclusion trait in the present study was lateral crossbite. Significant male dominance in the prevalence of malocclusion was observed, which has not been reported earlier in Finland. Orthodontic treatment of malocclusion traits was more common among females in Northern Finland. This study indicates that orthodontic treatment provided in childhood was, on average, adequate in reducing malocclusion traits to the level observed in the general population.

上海市浦东新区青少年错牙合畸形调查分析

目的了解上海市浦东新区生长发育期青少年错牙合畸形的患病情况,重点了解牙列拥挤、前牙深覆合覆盖和前牙反牙合的患病率。方法按Ａｎｇｌｅ分类法进行分类,以个别正常牙合和错牙合分类为标准。结果错牙合畸形的患病率替牙期为４４．０２％,恒牙期为４８．７８％。牙列拥挤、前牙深覆合覆盖和前牙反牙合的患病率替牙期分别为２２．７４％、１７．１８％和４．４４％;恒牙期分别为３２．３６％、１１．０６％和４．０７％。结论上海市浦东新区生长发育期青少年错牙合畸形的患病率替牙期与恒牙期无明显差异。提示前牙深覆合覆盖和前牙反牙合的患者并伴有上下颌骨异常需尽早矫治,以改善牙合颌关系。     

前磨牙拔除模式对不同错牙合畸形Bolton指数全牙比的影响

目的探讨前磨牙拔除模式对不同错牙合畸形Bolton指数全牙比的影响。方法选取180副牙性与骨性错牙合类型一致的患者模型,Ⅰ、Ⅱ、Ⅲ类每组60例,计算各组拔牙前和采用4种前磨牙拔除模式拔牙后的Bolton指数全牙比,以87%～89%为拔牙后Bolton指数全牙比参考值,对各组4种拔牙模式下Bolton指数全牙比的
异常率进行卡方检验。结果3组完整牙列Bolton指数全牙比差异有统计学意义（P=0.000）;Ⅰ、Ⅱ类组不同模式拔牙后Bolton指数全牙比异常率差异无统计学意义（P>0.05）,Ⅲ类组不同模式拔牙后异常率差异有统计学意义,拔除的异常率小于拔除（P=0.002）。结论从牙量协调的角度考虑,Ⅰ、Ⅱ类错牙合畸形采用4种拔牙模式均可,Ⅲ类错牙合畸形拔除的模式优于 。     

Need for interceptive intervention for malocclusion in 6-year-old Finnish children

Abstract The need for interceptive intervention for malocclusion was studied in a sample of 839 Finnish children aged 6 years. The children had participated in an organized preventive orthodontic program, and nearly 10% of them had received preventive or interceptive orthodontic treatment at the age of 3-5 years (stage I of the preventive orthodontic program of the author). Orthodontic intervention was estimated to be needed for 5.9% of the children due to crossbite of the permanent central incisors, to crossbite or scissors-bite of the permanent first molars, to ectopic eruption of the permanent first molars, to numerical variation of the permanent incisors, or to functional open bite. The need for further inspection in order to follow-up development of the dentition was noted in 2.7% of the children. The indications occasioning this consideration were initial severe crowding, extreme incisal overjet, and early loss of the primary mandibular canines. The relatively low prevalence rates seemed to indicate advantageous results of the preventive and interceptive orthodontic measures.
