520			_aEstablish an individualized 3D Counterparts{u2019} cephalometric analysis for a sample of Egyptian adults having average occlusion and balanced facial proportions. Secondary outcome was to evaluate the fitness of DiPaolo{u2019}s equation on the same group.Materials and methods: A cross sectional observational study was performed on 37 Egyptian adult subjects (18-25 y) having balanced facial proportions and Angle`s class I molar & canine relationship. Using the i-CAT CBCT machine. The three-dimensional assessment was performed by Anatomage software. Sex differences for all measurements and the fitness of DiPaolo{u2019}s equation on the sample were tested statistically for significance.Results: The intra-observer, inter-observer reliability for landmarks showed high concordance with identical ICC and CCC. Concerning the length measurements and ratios, the maxillary basal length (52.2mm) was larger statistically in males and larger than that of the mandibular length (47 mm) by 5mm with (1.1) ratio. The length of the middle cranial base (40.5 mm) was combatable with that of the mandibular ramus width (39.7 mm). Regarding the height measurements and ratios, the ratios of (PTFH / ATFH) was 65% in males and 62% in females, the ratio (ALFH / ATFH) was 55% in males and 54% in females and the ratio (PLFH /ALFH) was 54% in males and 50% in females without statistical significant differences. The inter-orbital width (97.9 mm) was double the basal width of either bases or equal to their sum. Moreover, equals the sum of the anterior and posterior lower facial heights. As a secondary outcome, the DiPaolo{u2019}s equation was evaluated for fitness on the sample but it was failed statistically
