Applied anatomy study related to implants in the temporal bone region / 华西口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the bone anatomic structure of the temporal bone region and provide reference in implant surgery in this region.</p><p><b>METHODS</b>Manual quantitative measurements of the bone structure were performed in 73 skull specimens (38 from male and 35 from female).</p><p><b>RESULTS</b>In the area of 800-1100 (right ear) and 16-22 mm from center of the external auditory canal in the temporal bone region, the minimum bone thickness is as follows 1100 6.77 mm in male, 5.18 mm in female; 1000 8.60 mm in male, 6.77 mm in female; 900 9.85 mm in male, 7.30 mm in female; 800 14.50 mm in male, 10.80 mm in female.</p><p><b>CONCLUSION</b>(1) In the temporal bone region, the area of 800-1100 (right ear) and 16-22 mm from center of the external auditory canal offers sufficient bone for implants. The length of implants should be as follows 1100 4-5 mm in male, 3-4 mm in female; 1000 4-7 mm in male, 4-5 mm in female; 900 4-8 mm in male, 4-6 mm in female; 800 4-12 mm in male, 4-8 mm in female. (2) Towards the external auditory canal and from 1200 to 1100, 1000 to 800, the bone became thicker, so, if no ample bone is available in the initial site, the location should be shifted anti-clockwise in right side (clockwise in left side) and closer to the external auditory canal. (3) The differences between male and female are statistically significant in the temporal bone region, so they should be treated distinguishingly during the clinical practices.</p>
