Guided Sausage Technique in Bone Regeneration As a Novel Digital Work Flow

Twenty sites with ridge defects will be recruited for this study. All investigations will be carried out in accordance with the 1975 Helsinki Declaration, as revised in 2013 for clinical approval. The purpose of the present study will be explained to the patients and informed consents will be obtained . Sites were randomly divided into 2 treatment groups .10 sites will be treated with bone graft (50%autogenous mixed with 50%xenograft) covered with bilayer collagen membrane without use of guide & 10 sites will receive the same treatment except it will be guided using digitally designed guide. Membranes in both groups will be stabilized by tacks. Following clinical parameters will be recorded: the wound opening of buccolingual distance between sutured flap margins with a UNC periodontal probe to the nearest millimeter at 2, 7 and 14 days, flap dehiscence. Also, bone gain and bone density will be assessed using cone beam computed tomography (CBCT) at baseline and 6 months post-surgery. The collected data was statistically analyzed at the different follow up periods.
