Abstract: PURPOSE: To study the clinical efficacy of small intestinal submucosa (SIS) absorbable biological membrane in alveolar bone defect repair. METHODS: A total of 102 patients with alveolar bone defect who received guided bone regeneration (GBR) in our hospital from January 2020 to January 2022 were selected and divided into Bio-Gide group (51 cases using Bio-Gide absorbable biofilm) and SIS group (51 cases using SIS absorbable biofilm) by computer random number generator. The perioperative related indicators, blood calcium, blood phosphorus, biocompatibility, periodontal attachment loss (PAL) length, pulp sensitivity, tooth mobility, alveolar bone volume and adverse events of the two groups were compared. Statistical analysis was performed with SPSS 24.0 software package. RESULTS: There was no significant difference in operation time, intraoperative blood loss, visual analogue scale (VAS) score of pain on the first day after operation, VAS score on the fifth day after operation, wound healing time, blood calcium and phosphorus levels before operation, 1 d and 12 d after operation, PAL length before operation, 3 months, 6 months and 12 months after operation, pulp sensitivity and tooth looseness grade 1 and 2 percentage at 3, 6 and 12 months after operation, bone width increase, bone height increase at 12 months after operation and adverse event rate between the two groups (P>0.05). Compared with Bio-Gide group, the wound healing time and biofilm absorption time were shortened in SIS group(P<0.05), and the incidence of rejection was decreased 12 d after operation (P<0.05). CONCLUSIONS: SIS absorbable biofilm and Bio-Gide absorbable biofilm have similar efficacy and safety in repairing GBR for alveolar bone defects, but the former is more biocompatible and the latter can provide longer barrier function.
