Attaining the appropriate relation of the denture base with the tissues for optimum retention and support poses various challenges. Retention and support of a prosthesis depend on capturing mucosa and limiting structures in undistorted form. The impression in the geriatric population and patients with maxillary and mandibular defects poses a challenge for prosthodontists. An alternate impression-making technique, including transcutaneous electric nerve stimulation (TENS), can be viable for these clinical cases. In the TENS technique, electrodes are placed on the region of the posterior triangle of the neck and the pre-auricular region simultaneously on both sides to instigate muscle contractions in the target area. An impression is obtained in physiological harmony with surrounding musculature after applying TENS. TENS can induce muscle contractions when applied <10 Hz, while >20 Hz can cause paraesthesia. This case report presents two cases rehabilitated with complete dentures in which ultra-low frequency (ULF) TENS (<4 Hz) has been used for impression making.
使义齿基托与组织达到适当关系以实现最佳固位和支持面临着各种挑战。假体的固位和支持取决于以未变形的形式捕获黏膜和限制结构。老年人群以及上颌和下颌缺损患者的印模给口腔修复医生带来了挑战。一种替代印模制作技术,包括经皮电神经刺激(TENS),对于这些临床病例可能是可行的。在TENS技术中,电极同时放置在颈部后三角区和双侧耳前区,以激发目标区域的肌肉收缩。应用TENS后,在与周围肌肉组织生理协调的情况下获取印模。当以<10 Hz的频率应用TENS时可诱发肌肉收缩,而>20 Hz会引起感觉异常。本病例报告介绍了两例使用全口义齿修复的病例,其中超低频(ULF)TENS(<4 Hz)已用于印模制作。
