Abstract

Purpose: To evaluate of the volumetric bone change after using liquid phase concentrated growth factor in open sinus lift surgery .Material and methods 12 pneumatized maxillary sinuses in edentulous or partially edentulous patients were divided randomly into 2 equal groups; Group (A), augmented by alloplastic bone graft Biphasic Calcium Phosphate (BCP). Group (B), augmented with BCP mixed with liquid phase concentrated growth factor (LPCGF). Visual Analogue Scale (VAS) was used to assess pain and swelling. CBCT was used to assess the volume by measuring height × surface area of augmented bone immediate and 6 months postoperatively. Clinical follow up period was at 1st, 2ndday then, after one week postoperatively. Results 12 sinus , bilateral 71.4%, unilateral 28.5%, female 42.8%, male 57.2% were subjected to sinus lift surgery. Mean age was 50y and average length of residual bone was 7 mm. There was no significant difference between the two groups regarding primary wound healing with percentage of success 71.4%. VAS scale representing swelling of 42.8% in group (A) and 28.5% in group (B). Pain score show decrease gradual till one week to be zero. In comparing between two groups, percentages of change in volume was highly significant (p=0.004) between two groups; in group (A) was 29.31±13.23 while, in group (B) was 2.58±1.75. Conclusion: Use of LPCG mixed with BCP bone graft to augment the sinus with open sinus lift surgery showed less bone resorption as it represented with low percentage of change in bone graft volume at 6 months postoperative .
