Concentrated growth factor and collagen as barrier materials in alveolar ridge preservation for posterior teeth:a prospective cohort study with one-year follow-up
摘要
Abstract
Objective This study aims to evaluate the efficacy of concentrated growth factor(CGF)membrane and collagen as barrier materials in sealing the alveolar socket in alveolar ridge preservation(ARP)in the posterior region during a one-year follow-up.Methods A total of 24 pa-tients who underwent ARP in the posterior region were selected for inclusion and randomly assigned to the CGF group(12 cases)and Collagen group(12 cases).The pa-tients in both groups underwent extraction of posterior teeth.The extraction sockets were filled with a bone sub-stitute to the level of the pre-extraction buccal and lingual or palatal alveolar bone plates.The wounds in the CGF group were closed with a fabricated CGF overlaying the upper edge of the bone substitute material,whereas those in the Colla-gen group were closed with Bio-Oss Collagen.The implants were placed after 6 months.The evaluation was based on implant retention,re-grafting rate,and vertical and horizontal alveolar ridge bone volume changes measured by cone beam computed tomography(CBCT).Data were statistically analyzed using SPSS 28.0 software.Results No patient withdrew throughout the follow-up period.No implant failure and no severe peri-implant or mucosal soft tissue compli-cations were observed.Six months after the operation,the degree of vertical alveolar ridge height resorption in the CGF group was lower than that in the Collagen group(P<0.05).There were no statistically difference between the groups at 1 year after the operation(P>0.05).The amount of bone reduction in horizontal alveolar ridge width showed no difference between the groups at 6 months and 1 year after surgery(P>0.05).Conclusion CGF membrane and Bio-Oss Collagen as barrier materials for posterior ARP inhibited reduction in alveolar ridge bone mass.关键词
