Adjustable impression tray for jaw cyst obturator

Abstract

The invention discloses an adjustable impression tray for a jaw cyst obturator. The adjustable impression tray comprises a handle, wherein an occlusal panel is connected to the end of the handle, a buccal side plate is connected to the side, close to the handle, of the occlusal panel, and a tongue side plate is connected to the side, away from the handle, of the occlusal panel; a plurality of fixing holes are formed in the occlusal panel and the buccal side plate; a fixing clamping ring is detachably connected to each fixing hole, a blocking rod is detachably connected to the center of each fixing clamping ring in a sleeving mode, and each blocking rod penetrates through the corresponding fixing clamping ring; and indication positioning devices matched with the fixing holes are detachablyarranged at the fixing holes, and are used for indicating and positioning the positions of the blocking rods; The adjustable impression tray further comprises patches, wherein each patch is located onthe inner side of the corresponding fixing hole corresponding to the corresponding blocking rod, and each blocking rod penetrates through the corresponding patch. When oral cavity mold taking is performed before the obturator is manufactured, the mold taking time can be saved, the mold taking precision is improved, the pain of a patient is relieved, and postoperative recovery of the patient is promoted.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustable impression tray of a jaw cyst stopper. Background technique [0002] Jaw cystic lesion is a multiple disease of the oral and maxillofacial region, which refers to a progressively enlarged cystic mass containing fluid in the jaw. Since the initial symptoms of the disease are not obvious and lack self-limitation, if the disease is not treated effectively in time, it may eventually cause destruction, absorption and even deformity of the jaw. [0003] Common clinical treatment methods include cyst curettage, jaw resection and reconstruction, and fenestration decompression. Among them, fenestration decompression is to destroy the integrity of the cyst cavity, reduce the pressure in the cyst to balance the pressure inside and outside the cyst or a negative pressure state, so as to achieve the purpose of shrinking the cyst and rebuilding the bone of the jaw; compa...

Problems solved by technology

[0005] At present, ordinary oral trays are mainly used to take impressions clinically. Before taking impressions, doctors need to manually adjust the angle between the outer and inner sides of the tray, punch holes in the tray, and make wax blocking sticks to temporarily fill the cystic cavity to prevent imprinting. The mold material overflows into the cavity; it is difficult to obtain the functional shape of the mucosa under stress for the cyst fenestration of the mucosa that is easy to sink and deform or the free end of the tooth is missing; the operation steps are cumbersome and time-consuming; it is difficult for beginners to take the mold. Accurate positioning of the defect area and the position of the tray; there is no stable support when taking the impression, and if the impression material shakes before it solidifies, it will easily affect the accuracy of the impression
