Application study of apical preservation combined with guided bone regeneration in jaw cyst surgery

ObjectiveTo explore the clinical effects of periapical curettage preservation combined with Bio-oss bone meal/Haiao artificial biomembrane in jaw cyst surgery.

MethodsFifty-five patients with jaw cyst were divided into the group A(15 cases) and group B(40 cases).The group A was treated with the periapical curettage preserving the root tip, bone meal covering the lack of part of the root exposed to jaw and biofilm covering.The group B was treated with simple cyst excision combined with apicoectomy.All patients were followed up for more than 12 months.The recovery of tooth function, bone regeneration and reconstruction of jaw defects between two groups before and after operation were compared.

ResultsAfter operation, the normal function recovery in cyst involved teeth in group A was faster than that in group B(P < 0.01).The osteogenic effect in bone graft area in group A was better than that in autogenous healing area.

ConclusionsThe efficacy of apical preservation combined with guiding bone regeneration in jaw cyst excision is good and reliable.
