I industry report logical examination included freezing and H&E staining, examination using light microscopy. Three implants used in this case were root form spiral SLA coated implants. After implant incursion, implant coverswereconnectedandtheflapwassuturedus- ing 3-0 silk sutures. Amoxicillin 500 mg TID with 250mg of metronidazole TID was recommended for seven days after surgery. _Results Thebovinelyophilizedatelo-collagencontaining Xenograft (HYPRO-OSS™, Bioimplon GmbH) was usedforfillingtheSinus.Thismaterialwashydrated with 0.9% Saline before the implantation and con- sequentlythematerialwaspastywithexcellenthan- dlingproperties.Haemostaticeffectappearsimme- diately after placing into the operation site. Hydra- tion increased the volume of the grafting material and there was no tension on sinus membrane while condensation of the grafting material. Placing the membrane (Hypro-Sorb M™) was easy, good han- dling,cutting,goodcapillaryeffectandstableatthe site of surgery. Follow up a week after surgery pre- sented very good healing, minimal swelling; no membrane exposure or flap opening, good wound integration or minimal discomfort for patient was reportedinthefollowingdaysafterthetwosurger- ies. Theboneheightofthenewbonewas11–1mmat therightsinus(2–3mmofnaturalbone),thedensity of the bone was similar to Bone type II. Insertions torquesofthetreeimplantsplacedattherightsinus were metered by manual torque wrench and found to be 28–30 Ncm. The histological slides demon- strated a large volume of high quality bone tissue andminimalconnectivetissue.Newbonematrixand few old bone materials were seen in large magnifi- cation. _Conclusion Lyophilized atelo-collagenated Xenograft (Hypro-Oss™) that is composed of 30% collagen typeIfreeofatelo-peptide(atelo-collagen)withna- tive osteoinductive elements (TGF, BMPs, IGFs) and 70%nativeosteoconductivebovineHydroxyapatite components, can be used as an efficient inductive bonegraftingmaterialforguidedboneregeneration and sinus augmentation. This work can show that this Xenograft has several advantages due to the production process that preserves the organic ele- ments as bone growth factors that are responsible for accelerating the bone regeneration period and resultinginoptimalbonequalityandvolumeforop- timisingimplantplacement.Goodbonedensitywas approvedbyhighimplantinsertiontorqueandhigh volume of calcified tissue in histological slides.
