Ten screws were untreated and used as controls. The remaining 10 screws were coated with calcium phosphate and following cross-linked with ostrich eggshell membrane protein. All rabbits were sacrificed six weeks after the surgery. Peri-screw tissues were evaluated by </span>micro-computed tomography (&micro;-CT), histological and histomorphometrical methods.&nbsp; </span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:115%"><span calibri=""><b><span new="" roman="" times=""><span style="color:black">Results:</span></span></b><span new="" roman="" times="">&nbsp;<span style="color:black">The &mu;-CT assessments indicated that the experimental group had significantly higher mean </span>bone surface area (BSA) and trabeculae number (TbN) than those of the control group (<i>p </i>˂ 0.05). Bone surface area (BV), trabecular separation (TbSp), trabecular thickness (TbTh), and bone mineral density (BMD) scores of the control and experimental groups were quite similar (<i>p </i>> 0.05). The vascularization score of the experimental group was significantly higher than the control group (4.29 vs. 0.92%). No sign of the graft-versus-host reaction was observed. </span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:115%"><span calibri=""><b><span new="" roman="" times=""><span style="color:black">Conclusion:</span></span></b><span new="" roman="" times="">&nbsp; <span style="color:black">Our findings reveal that coating Ti alloy implants with calcium phosphate cross-linked with ostrich eggshell membrane protein increases the osseointegration of Ti alloy screws by increasing the bone surface area, number of trabeculae and vascularization in the implant site.</span></span></span></span></span><br> &nbsp;</span> Biomimetics, Body fluids, Histology 38 45 http://ibj.pasteur.ac.ir/browse.php?a_code=A-10-5393-1&slc_lang=en&sid=1 Mehmet Bahadır İlik bahadirilik85@hotmail.com 0000-0001-6768-5428 No Sağlık Bakanlığı, Alanya ADSM, Oba Mahallesi, Fidanlık Caddesi, No:85, Alanya, Antalya, Türkiye Ercan Durmuş ercdur@hotmail.com 0000-0003-4851-4230 No Selçuk University Faculty of Dentistry, Department of Oral and Maxillofacial Surgery, Kampüs 42080, Konya, Türkiye İlhami Çelik icel@selcuk.edu.tr 0000-0002-3587-7609 Yes Selçuk University Faculty of Veterinary Medicine, Department of Histology and Embryology, Kampüs 42031, Konya, Türkiye
