微型种植体支抗正畸过程中的稳定性 总被引:6,自引:1,他引:6
背景:微型种植体作为绝对支抗应用于正畸治疗中存在的最大问题是稳定性。目的:应用微型种植体支抗内收上颌前牙,观察上颌前牙及第一磨牙位置的变化,评价微型种植体作为强支抗在正畸治疗过程中的稳定性。设计、时间及地点:对比观察实验。于2006-10/2007-12选择河北医科大学第二医院口腔正畸科门诊患者。对象:选取门诊就诊的双颌前突或上颌前突患者20例,男6例,女14例;年龄15-27岁,平均20.7岁。矫治设计拔除4颗第1双尖牙或上颌第1及下颌第2双尖牙。方法:随机选择10例应用上颌后牙区微螺钉型种植体支抗内收前牙,微型钛钉直径为1.5mm,长度为8mm,由西安中邦钛生物制品有限公司提供。所有种植体由同一术者采取相同的手术方式植入。另10例采用腭杆加口外弓的支抗方法。主要观察指标:治疗前及关闭拔牙间隙后拍摄X射线头颅侧位片,测量前牙内收情况、软组织变化及磨牙支抗的变化。结果:①微型钛钉种植体在拔牙间隙关闭的过程中保持了稳定,成功率89%。②种植体支抗治疗后上中切牙倾角及凸距的减少量明显多于非种植体强支抗治疗后的减少量,差异有显著性意义(P〈0.01);种植体支抗组磨牙位移明显少于非种植体强支抗组,差异有显著性意义(P〈0.01)。结论:微型钛钉种植体作为稳定的骨性正畸支抗,可以实现理想的支抗控制效果。 相似文献

The aim was to describe quality of care from a patient perspective among adolescents receiving orthodontic treatment and to assess the relationship between quality of care and outcome-related aspects. The research design was cross-sectional. The sample consisted of 151 young people (mean age 17.1 years, SD: 2.2; 53% girls and 47% boys) receiving orthodontic treatment in the Stockholm region in Sweden (response rate 75%). Data were collected using the Quality from the Patient's Perspective questionnaire. The highest quality of care perceptions were noted on items dealing with receiving the best possible orthodontic treatment and being treated with respect. Less favourable perceptions of the quality of care were found regarding the opportunity to participate in the decisions related to the orthodontic treatment. In order to improve the quality of care a more active involvement of these patients in the decision-making process is suggested. The item 'I received the best possible orthodontic treatment' noted the highest subjective importance rating. The youngest participants reported the most favourable scores and the oldest the least. The majority (74%) reported that they were 'completely satisfied' with the result of the orthodontic treatment. However, 52% claimed that they had not followed all of the advice obtained during the treatment period, and 29% indicated some or more hesitation about attending the same dentist for future treatment. 相似文献

背景:微型种植体植入过程中植入的位点和方向、微型种植体加载后的移动、牙齿移动后与微型种植体接触等都将导致牙根的损害。目的:观察微型种植体负载不同周期后与其邻近的牙根和牙周组织的变化,以及牙周组织中骨保护素的表达变化。方法:beagle犬2只,在犬上颌第2,3,4前磨牙和下颌第2,3,4前磨牙及第1磨牙的牙根之间的唇侧牙槽间隔邻近牙根处各植入1枚微型种植体。每只犬各植入微型种植体14枚,上颌6枚,下颌8枚,其中上颌有2枚微型种植体设置为对照组不加载,其余均为实验组加载正畸力。微型种植体植入后2周,通过镍钛螺旋拉簧为微型种植体加载150 g的水平力。分别于微型种植体负载4周、8周后处死beagle犬,完整切取牙齿连同牙槽骨,苏木精-伊红染色观察以及免疫组织化学法检测牙周组织中骨保护素的表达变化。结果与结论:当微型种植体邻近牙根时,牙根表面牙槽骨出现吸收陷窝;微型种植体负载与牙根相向的水平力后,牙槽骨吸收变的更加活跃。当微型种植体接触牙周膜时,牙根表面的牙骨质局部严重吸收甚至达牙本质层。微型种植体接触牙根后负载,大面积的牙骨质全层吸收,牙本质暴露在外并出现吸收。对照组骨保护素出现强阳性表达,8周表达显著;8周实验组的骨保护素阳性表达明显下降(P〈0.01)。结果表明,微型种植体邻近牙根植入后,邻近微型种植体的牙根及牙周组织均受到不同程度的损伤。微型种植体负载与牙根相向的水平正畸力,短期内对牙周组织中骨保护素的表达影响较小,随着负载周期的延长,压力显著抑制了骨保护素的表达。提示当发现邻近牙根植入后,微型种植体不应再负载与邻近牙根相向的正畸力,而应该及时取出待牙根自行修复,避免对邻近牙根的损伤进一步加重。 相似文献

目的比较微种植体支抗和自攻钛种植体支抗的临床应用价值。方法选择接受口腔科正畸治疗的患者作为研究对象,随机分为接受微种植体支抗治疗的对照组及接受自攻钛种植体支抗治疗的观察组。比较两组患者的治疗后牙齿功能相关指标、X线头影测量软硬组织变化、龈沟液中炎症因子水平等差异。结果治疗后,观察组患者的牙龈、出血指数以及松动度均低于对照组,咬合力和咀嚼效率均高于对照组(P0.05)。接受矫治后,两组患者的炎症因子水平均有上升,但是两者之间无明显统计学差异(P0.05)。观察组患者接受矫治后的龈沟液中炎症因子水平明显低于对照组患者(P0.05)。结论自攻钛种植体支抗可以有效减少牙齿损伤,优化口腔软硬组织指标值,不增加牙龈炎症水平,是一种安全高效的口腔矫治方式。 相似文献

Purpose. This study reports the development and clinical trial of a new treatment program for persistent developmental stuttering in adolescents and adults. The treatment is based on the operant procedure of self-imposed time-out. This involves the person stopping speaking for a short period after each stutter.
Method. Twenty-two participants completed Stage 1 (Instatement and Generalisation) of the program and 18 completed Stage 2 (Maintenance) of the program. Stuttering outcome was measured from independent audio and video recordings made outside and inside the clinic, before and after treatment. Speech naturalness was measured at the end of Stage 1. Secondary analyses were conducted to investigate whether responsiveness to the program was related to stuttering severity or age. Participants completed an extensive self-report inventory at the end of treatment.
Results. There was a range of responsiveness to the treatment, with more than half the participants reducing their stuttering by more than 50%. Participants with more severe types of stuttering appeared to respond better but no other predictors of responsiveness were identified. Speech sounded reasonably natural after treatment. Participants' perceptions of the treatment were for the most part positive with the majority reporting that the treatment was easier to use and more effective than treatment based on prolonged-speech.
Conclusions. The self-imposed time-out treatment program reported here is clearly effective for a significant number of adolescents and adults who stutter. Given that it does not require speech restructuring and the constant attention to speech that this involves, this could be a treatment of choice for those who are likely to respond. Consequently, further research is needed to determine which clients seeking behavioural treatment for their stuttering will benefit most from this program. Further research is also needed to determine the extent to which the effectiveness of time-out is increased when combined with other behavioural treatments. 相似文献
