Objective: To establish the database on typing of Chin es e condyle head by skull base position X ray analysis. Methods: 51 Chinese volunteers (male 33, 65 condyles; female 18, 35 condyles) accep ted skull base position X ray inspection. Then the 100 condyle images were ana lyzed and the contribution of the types among sexes and sides were also analyz ed. Results: The types of condyle were divided into A,B,C, D,E(E1,E2) and F(F1,F2).Among all condyle types, type A was accounted for 41.0% , while type F1 only 1%. The contribution of the types between left and right si des was almost the same. 51% (26 pairs) of the two condyles in the same person share the same type, the other 23 pairs of condyles were in different types (mal e 39.1 %, female 60.9%). Conclusion: The morphology typ ing of condyle heads by skull base position X ray analysis may be reference to clinical application.
