Abstract

Introduction: The need to extract permanent teeth for the correction of dento-maxillary anomalies remains even today a controversy in orthodontic therapy. The purpose of this study was to assess the orthodontist's point of view on the extraction and non-extraction methods used in orthodontic treatments, regarding clinical experience.

Material and methods: A de novo conceived questionnaire was elaborated by means of Google Forms and it comprised 22 questions regarding gender, age, different proprieties and aspects of both extraction and non-extraction methods and the percentage of treated patients who developed an increase in dental sensitivity and caries activity following the therapeutic stripping procedure.

Results: 204 orthodontists answered the questionnaire. The respondents chose dental stripping (IPR-interproximal reduction) as the most used non-extraction method in their orthodontic practice with 34,3%, followed by over-expansion and dental stripping 24%. The probability that females will try to avoid dental extractions is 1.888 times higher compared to males. The association is statistically significant (p-value 0.0336). 70,1% of clinicians state that they use dental stripping as a non-extraction method to gain space even when there is NO Bolton discrepancy. In Class III cases, for reducing crowding and correcting the dental relations, 65.2% of doctors opt for dental stripping, while 34.8% do not avoid the extraction of a lower incisor.

Conclusions: Among the non-extraction methods for creating space, the most used by the surveyed orthodontists was dental stripping IPR. Tooth extraction remains a solution used by orthodontists for treating dentomaxillary disharmonies with crowding.

关于正畸治疗中拔牙和非拔牙方法的统计研究
导言:时至今日,是否需要拔除恒牙来矫正牙颌畸形仍然是正畸治疗中的一个争议焦点。本研究的目的是根据临床经验,评估正畸医生对正畸治疗中使用的拔牙和不拔牙方法的看法:通过谷歌表格(Google Forms)编制了一份全新的调查问卷,其中包括 22 个问题,涉及性别、年龄、拔牙和非拔牙方法的不同特性和方面,以及在治疗性剥离过程后牙齿敏感度和龋齿活动增加的患者比例。结果:204 名正畸医生回答了调查问卷,其中 34.3%的受访者选择牙齿剥离(IPR-近端减小)作为其正畸实践中最常用的非拔牙方法,其次是过度扩张和牙齿剥离,占 24%。女性尽量避免拔牙的概率是男性的 1.888 倍。这种关联具有统计学意义(p 值为 0.0336)。70.1%的临床医生表示,即使在没有波顿不一致的情况下,他们也会使用牙齿剥离作为一种非拔牙方法来获得空间。在 III 类病例中,为了减少拥挤和矫正牙列关系,65.2% 的医生选择牙列剥离,而 34.8% 的医生不避免拔除下切牙:在创造空间的非拔牙方法中,受访正畸医生使用最多的是牙列剥离 IPR。拔牙仍然是正畸医生治疗牙颌不协调和牙列拥挤的一种方法。
