Application of a cyst plug in drainage after marsupialization of jaw cysts

Purpose To introduce the design and fabrication of two types of cyst plugs and their application in drainage following marsupialization of jaw cysts. Methods The clasp-retained cyst plugs were classified into two types, conventional and denture-like type according to their different function, and steps and procedures for making cyst plugs were described respectively. Results Cyst plugs were used for 32 lesions in molar regions, 7 in premolar and 4 in anterior regions. There were 35 conventional and 8 denture-like types, which kept cyst opening unobstructed in all patients without complications associated with these devices. Conclusions The clasp-retained cyst plug is a better drainage device for marsupialized jaw cysts and denture-like type can temporarily replace the lost tooth postoperatively.
