The stainless steel crowns (SSCs) placed using the Hall technique disrupt the occlusion, but stabilization appears to occur within a short period post-placement. Negligible understanding and comprehension is presently handy about the changes in overbite and bite force after placement of stainless steel crown using the Hall technique in children.
AIM/HYPOTHESIS: To evaluate the digital occlusal analysis of vertical dimension and maximum intercuspal position to understand the changes in overbite and bite force after placement of stainless steel crown using the Hall technique.
Twenty children who needed treatment for the carious tooth with decay extending to enamel and dentin and multisurface caries were managed using the Hall technique. Following that, overbite measurement for vertical dimension was carried out clinically using digital vernier calipers. Later, the T-Scan III was used for measuring occlusal load at the maximum intercuspal position. The bite force and occlusal premature contacts were digitally analysed and recorded pre-operatively, immediately after placement of SSC and after 1 month follow-up period.
A significant result in the vertical dimension, bite force on crowned tooth, and significant reduction in the prematurities were seen from baseline to one-month follow-up.
There was an occlusal re-equilibration attained after 1 month.
使用 Hall 技术放置的不锈钢冠（SSC）会破坏咬合，但在放置后很短的时间内似乎会稳定下来。目前对于使用 Hall 技术在儿童中放置不锈钢冠后覆𬌗和咬合力的变化，人们的了解和理解微乎其微。
目的/假设：评估垂直向的数字咬合分析和最大牙尖交错位，以了解使用 Hall 技术放置不锈钢冠后覆𬌗和咬合力的变化。
使用 Hall 技术治疗 20 名需要治疗龋齿的儿童，这些儿童的龋齿已延伸至釉质和牙本质，并有多个表面龋齿。之后，使用数字游标卡尺在临床上进行垂直向覆𬌗测量。然后，使用 T-Scan III 在最大牙尖交错位测量咬合负荷。在术前、放置 SSC 后即刻和 1 个月随访期间，对咬合力和咬合早接触进行数字分析和记录。
从基线到 1 个月随访时，垂直向、覆盖牙的咬合力以及早接触的显著减少都有显著的结果。
在 1 个月后达到了咬合的再平衡。
