Abstract：Objective To analyze the clinical effect of immediate loading restoration of 6 to 9 dentures with a short den-tal arch in the anterior region for maxillary edentulous implant fixed restoration.Methods Clinical and radiographic da-ta of 10 patients,who underwent immediate loading restoration with a short dental arch for maxillary edentulous implanta-tions in the Department of Implantology,Tianjin Stomatological Hospital,from July 2020 to December 2022,were collect-ed for retrospective analysis.Implant placement was preoperatively designed,and a guide plate was fabricated.Four im-plants were implanted between the anterior walls of bilateral maxillary sinuses with immediate restoration of 6 to 9 den-tures.Maxillary sinus floor elevation was performed in the distal molar region for simultaneous or delayed implant place-ment,and permanent restoration with a monolithic bridge was conducted after osseointegration of distal molar implants.The implant survival rate,marginal bone loss,restorative complications,and recorded patient-reported discomfort from immediate restoration to permanent restoration were analyzed.Results A total of 40 implants were placed in the anteri-or region of 10 patients.The time of wearing short dental arch for temporary restorations was an average of(13.4±4.5)months from immediate restoration to permanent restora-tion,with no implant loss and a 100％implant survival rate.The average marginal bone loss was(0.69±0.51)mm,and no extensive marginal bone loss was observed.Resin restoration fracture occurred in 5 cases,with fracture time ranging from 5 to 16 months after immediate restoration.After immediate restoration,4 patients reported speech impairment,3 complained of cheek/lip biting,and 8 expressed dissatisfaction with masticatory function.Conclusion Immediate loading restoration with a short dental arch for maxil-lary edentulous implantation is a feasible solution for patients with insufficient bone volume in the maxillary posterior re-gion requiring maxillary sinus floor elevation.No implant-related complications occur during the transitional restoration phase,and restorative complications are manageable.Further research is needed to strengthen the intensity of temporary restorations and improve patient comfort.
