[Lower teeth anesthesia in patients with limited mouth opening].

Limited mouth opening is a common pathology in dental practice. Dental treatment of these group patients is hindered by low access to oral cavity, which complicates operative, prosthetic and surgical interventions. Local anesthesia is also difficult due to changes in anatomical landmarks, changes in bone structures and soft tissues ratio. M.M. Weisbrem and Gow-Gates technique in case with limited mouth opening 1-2 cm is ineffective. Mandibular convention block is more universal, as it is oriented to bone structures without binding to soft tissues. Variation of local anesthesia techniques at a various mouth opening degrees are offered.
