IN VITRO EVALUATION OF SURFACE CLEANING METHODS IN TWO DIFFERENT IMPLANT DEFECT ANGULATIONS: A PILOT STUDY

Recently, prominence has been given to the use of power abrasive devices to improve the cleaning effectiveness on contaminated implant surfaces, and in an in-vitro study, it has been stated that air powder abrasion is the most efficient and less damaging cleaning modality in comparison to sonic scaler and curette for different defect morphologies15. However, there is a paucity of information on the use of air powder abrasive devices to reach a definite conclusion and it is warranted to perform comparative study designs evaluating the effectiveness. There is a new air-abrasive material called trehalose, a natural noncariogenic disaccharide with a good taste. It is thermostable and approved for use in food processing16. It is highly water-soluble (689g/L) with a pH of 6.4. In one clinical study, subgingival air-polishing with trehalose powder has revealed encouraging clinical outcomes17.
Therefore, the aim of this study is to investigate the cleaning potential of an air abrasive device with trehalose powder on implant surfaces in comparison to Er: YAG laser application in an in-vitro model of two different defect angulations.

近期，对使用动力磨削设备以提高污染植入物表面的清洁效果的关注度日益提升。在体外研究中，已有观点指出，与超声波洁牙器和刮刀相比，气力喷砂是针对不同缺陷形态最为高效且损害较小的清洁方式。然而，关于气力喷砂设备使用的相关信息尚显匮乏，有必要进行对比研究设计以评估其有效性。目前，存在一种名为麦芽糖的新型气力磨削材料，它是一种天然的非致龋二糖，具有宜人的口感。麦芽糖具有热稳定性，并获得用于食品加工的批准。其高度水溶性（689g/L），pH值为6.4。在一项临床研究中，使用麦芽糖粉末进行龈下气力抛光显示出令人鼓舞的临床效果。因此，本研究的目的是探究使用麦芽糖粉末的气力磨削设备在体外模型中对植入物表面的清洁潜力，并将其与Er: YAG激光应用进行对比，评估两种不同缺陷角度的效果。
