The objective of this study was to evaluate a newly developed method to measure the height of the crown at intercuspal position. The heights of 31 crowns were measured using partial bite registrations taken with black silicone (Bite -checker GC Corp, Tokyo, Japan) from each case at 3 stages of no crown, before and after completing occlusal adjustment of each crown. Perforations in the bite registrations were defined as occlusal contacts. A space created between occlusal surfaces of the unadjusted crown and the opposing teeth was considered to be the crown height. The thickness of black silicone was measured with a Visual Scaler Meter (MCP-550, Ono Sokki, Japan). The heights of crown were
284.7±177.5um higher at the IP.
