Introduction
Suction Effective Mandibular Complete Denture (SEMCD) is being given great attention in the world recently. If you wear an ill fitting denture, it requires constant attention not to drop out during mastication. SEMCD is a well fitting denture, so it relaxes the patients and enables them to enjoy their life.Difference between the conventional denture treatment and SEMCD treatment.
Conventional denture fabrication technique with stick compound advocated by Dr.Boucher in the 1960’s is a far cry from SEMCD techniques. This conventional treatment theory is that denture flange should extend to the muscle attachment to cover the maximum ridges surfaces in order to get a denture stabilization. This is a correct theory. However, lately there are not many dentists who can teach accurate compound technique; therefore, this compound technique became less popular. The detailed compound technique is not well described even in the popular denture book ‘Prosthodontic Treatment for Edentulous patients’ On the other hand, whether it is maxillary or mandibular denture fabrication, SEMCD treatment emphasises on and pays attention to the oral mucosa. The maximum suction is acquired by having tight contact between denture base and oral mucosa and creating negative pressure between mucosa and the denture base during swallowing. Once the main focus for the treatment has changed, obviously the focus for the preliminary impression, custom tray fabrication method and shape of custom tray and method of final impression will be changed accordingly. The clinical success will be achieved without mixing up these two different concepts together (Fig.1 A and Fig. 1 B).
