Abstract：Objective To measure the vertical thickness of the palatal bone of people who have individual normal occlusion in Henan Province,look for the suitable site for palatal micro screw implant so as to provide conveniences for anchorage implant and lingual orthodontics.Methods A total of 52 cases were selected,including 15 adult female and 37 adult males.256 spiral CT (Philips Brilliance iBT)was used to scan the specimen cranio maxillofacial region,The vertical thicknesses of the palate bone tissue were measured and collected.The data was applied with software SPSS 17.0.Results ①Average bone thickness of 37 palate virtual location of implants:the maximum bone thickness part was P0 +D2,where the average bone thickness was(18.7 ± 3.0)mm;the minimum bone thickness part was P5 +D2,where the average bone thickness was(2.8 ±1.1)mm.The average thickness of the bone of the four location on the coronal plane where the incisor foramen lay on were all greater than 15 mm.②When using the 8 mm micro -implant,the best 10 suitable places were P0 -D2,P0 -D1,P0 +D1,P0 +D2,P1 -D2,P1 -D1,P1D0,P1 +D2,P2 -D3,P2 +D3.The highest implant rate was 100%,the lowest implant rate was 63.5%.The implant rates of the four location on the coronal plane where the incisor foramen lay on:P0 -D2,P0 -D1,P0 +D1,P0 +D2 were all 100%.Conclusion ①It was suitable for adult implantation in palatal area within 5 mm behind the incisor foramen.②256 CT could contribute to the implantation of palatal implant.
