Abstract

Determining the maxillomandibular relation in patients requiring functional occlusal rehabilitation is critical for the success of restorative treatment. In this study, the effects of centric relation records obtained by two different methods: bimanual manipulation with intraoral scanning, and anterior plateau with mandibular movement tracking/analysis device on restorative occlusal surface adaptation were compared both qualitatively and quantitatively. Twelve patients with posterior support loss were included. In the first method, centric relation determined by bimanual manipulation was transferred to the digital environment using an intraoral scanner. In the second, centric relation determined with anterior plateau was recorded and digitized via a mandibular movement tracking/analysis device. Based on these records, restorations were fabricated, and clinical adaptation was evaluated qualitatively by occlusal adjustment time, number of articulation papers, and adapted area, and quantitatively by calculating adapted surface area. Qualitative analysis showed restorations produced with anterior plateau and the mandibular movement tracking/analysis device had significantly lower adjustment scores. Quantitative analysis revealed these restorations exhibited smaller adapted surface areas compared to those produced using bimanual manipulation with intraoral scanning. In conclusion, repeated recording with the anterior plateau and use of a mandibular movement tracking/analysis device resulted in restorations with superior static occlusal adaptation, and may be considered an effective approach to improving restorative occlusal outcomes.
