Autogenous Tooth Sticky Bone Graft for Maxillary Radicular Cyst Defects: A Retrospective Case Series

Background/Objectives: Radicular cysts (RCs) in the maxillary anterior aesthetic zone can cause substantial buccal bone loss and complicate implant rehabilitation. This retrospective case series evaluated autogenous tooth sticky bone (ATSB) from impacted third molars, covered with concentrated growth factor (CGF) membranes, for reconstructing these defects before delayed implant placement. Methods: Twenty patients with maxillary anterior RC-associated defects and ≥2 nonfunctional impacted third molars were treated under general anesthesia. ATSB was prepared chairside from partially demineralized dentin matrix (425–850 μm) and autogenous fibrin glue, placed after cyst enucleation, and covered with two CGF membranes. Implants were placed after 4 months. Clinical records, panoramic radiographs, and cone-beam computed tomography (CBCT) scans were reviewed. Results: The cohort comprised 12 males and 8 females (mean age, 31 years; range, 20–40). All donor and recipient sites healed uneventfully, without recorded infection or graft failure. Four-month CBCT showed increased radiopacity and trabecular-like structures within the defects. All implants achieved primary stability (implant stability quotient > 70) and showed radiographic findings consistent with osseointegration at 3 months; definitive restorations were recorded as functionally and aesthetically acceptable. Conclusions: In selected patients, ATSB with CGF membrane coverage may be a feasible option for post-enucleation reconstruction and delayed implant rehabilitation without an additional bone-harvesting site. Controlled studies with volumetric, histological, and long-term assessment are needed.
