DEVICE FOR SHIELDING TEETH TO BE TREATED

摘要

The invention relates to a device for shielding teeth to be treated in order to prevent an inflow of liquid, such as saliva or blood for example, and to a use of the device according to the invention. The invention relates to a partial dental dam (1) for protecting teeth to be treated, comprising a tensioning cloth (2) made of an elastic material and two actuation elements (3) arranged on opposing ends of the tensioning cloth (2). The tensioning cloth (2) is designed to be introduced into at least one intermediate tooth space (11) from the occlusal side in a first tensioned state, which can be achieved by pulling apart the actuation elements (3) in a tensioning direction (90), and to sealingly rest against the interdental gingiva and the approximal surfaces of the teeth (10) forming the at least one intermediate tooth space (11) in a second state after being introduced into the at least one intermediate tooth space (11). Each actuation element (3) rests against at least one tooth (10) and/or against the surrounding gingiva in the second state. The invention further relates to the use of the partial dental dam according to the invention. The tensioning cloth (2) is elongated by pulling the actuation elements (3) in the tensioning direction (90); the tensioning cloth (2) is introduced into at least one intermediate tooth space (11) from the occlusal side in the elongated state; and the tensioning cloth (2) is brought to rest against the interdental gingiva and the approximal surfaces of the teeth (10) forming the at least one intermediate tooth space (11) by releasing the tensioning force. Each of the actuation elements (3) rests against at least one tooth (10) and/or against the surrounding gingiva.
