An accurate impression is an essential procedure for fabricating indirect fixed restorations. To achieve a precise final impression, the management of gingival tissue is without doubt a crucial.
To evaluate the use of different gingival displacement techniques among dental clinicians and to assess their associated knowledge and technique preferences.
A self-designed survey was created electronically and sent to a list of dentists. The survey was composed of multiple sections. Participants who stated that they do not use GD methods were asked to answer the survey questions based on their knowledge. Descriptive statistics were generated, andChi-square test was used to examine the association between the different variables.
A total of 188 dentists participated in this study. The majority 144 (76.6%) use GD in their practice. When asked which technique yields a more accurate impression with lower incidence of repeating the impression, 93 (64.6%) reported retraction cord technique with a hemostatic agent results in a higher impression accuracy, while only 14 (9.7%) declared the retraction paste technique as being more accurate.
The cordless GD technique is believed to be easier, faster, and less traumatic to the gingival tissues, nevertheless, the outcome of dental impressions is believed to be more predictable with the use of conventional retraction cords and hemostatic medicaments.
准确的印模是制作间接固定修复体的必要程序。为了获得精确的最终印模,毫无疑问,对牙龈组织的管理是至关重要的。
评估牙科临床医生中不同牙龈移位技术的使用情况,并评估他们相关的知识和技术偏好。
我们设计了一份电子调查问卷,并将其发送给一组牙医。该调查问卷由多个部分组成。对于那些表示不使用 GD 方法的参与者,要求他们根据自己的知识回答调查问题。生成了描述性统计数据,并使用卡方检验来检验不同变量之间的关联。
共有 188 名牙医参与了这项研究。其中 144 名(76.6%)在实践中使用 GD。当被问及哪种技术能获得更准确的印模,且重复印模的发生率更低时,93 名(64.6%)报告说,使用带止血剂的收缩线技术可获得更高的印模准确性,而只有 14 名(9.7%)表示收缩膏技术更准确。
虽然无绳 GD 技术被认为更容易、更快且对牙龈组织的创伤更小,但使用传统的收缩线和止血药物,认为牙科印模的结果更具可预测性。
