Clinical application of concentrated growth factor combined with bone substitute materials in maxillary sinus lateral wall fenestration and elevation surgery
Objective To investigate the clinical efficacy of concentrated growth factors combined with bone substitute materials in lateral wall fenestration lifting procedures of the maxillary sinus.Methods A total of 30 cases of maxillary posterior missing teeth with insufficient vertical bone height were collected between September 2020 and December 2021.Bone augmentation using lateral wall fenestration lifting of the maxillary sinus combined with concentrated growth factors and bone substitute materials was performed and immediate or delayed implant placement was performed on 30 implants,and the percentage of alveolar bone height and vertical bone height resorption obtained at 6-8 months after surgery was observed over an average follow-up period 12±2.5 months.Results All implants achieved good clinical efficacy during the postoperative follow-up period.The implant integrated well with the surrounding bone,and the vertical bone height obtained by maxillary sinus lift was 8.81±0.76mm at 6-8 months postoperatively,with a percentage of vertical height resorption of 6.3%±0.6%.Conclusions Concentrated growth factors combined with bone substitute materials achieve good short-term outcomes in lateral wall fenestration lift of the maxillary sinus,but their long-term effects need to be observed in further follow-up.
