Abstract: The limitation of mouth opening, which can appear during irradiation, could impede the prosthetic treatment in particular when taking an impression. Thus, we are usually induced to choose a modified impression procedure such as: the technique of flexible impression tray, the sectorial system of the commercial impression tray with securing screws, the individual dental tray with pins and the locking latch technique. The dental occlusion registration can also be impeded by the limitation of mouth opening leading to teeth setting errors. In this context, we refer to the Sears technique based on occlusion release allowing to have a more or less wide occlusion field. Lately, newly developed sectioned denture showed some improvement in the treatment of patients with limitation of mouth opening. In addition, recent developments in the field of dental materials have overcome certain disadvantages of the acrylic resin by the appearance of new forms of denture materials such as thermoplastic resin.
