The aim of this study was to assess splitting and spreading of atrophic ridges to place dental implants.It was to detect any significant difference in bone gain before andafter ridge splitting. The study used twelve implants to replace missing upper posterior teeth.The patients were chosen from the outpatient clinic of the Oral medicine, Oral Diagnosis and periodontology department,CairoUniversity.Allpatientswere medically free,with no pathological conditions in the jaw bones.The edentulous sites were deficient in the horizontal dimension,requiringaug mentation. All patientsreceived implants after aridge splitting procedure. The split crest procedure involved the use of piezoelectric tips to perform the bone cuts and chisels to widen the bone.A resorbable collagen membrane(BIOCOLLAGEN®) was used tocover the implants. Radiographic assessment was performed at 3 intervals preoperative, immediately postoperative and 6 months postoperatively.Assessment included the amount of bone gain in width,the stability of the results after a period of6 months, and marginal bone loss around the implant. CBVT was used to acquire there measurements ,by cross-sectional and longitudinal cuts. The statistical analysis revealed significant in crease in bone width after ridge splitting and spreading
