Effect of mandibular complete dentures relining on occlusal force distribution using T-scan system

Abstract

Background This study aimed to evaluate the effect of mandibular complete dentures relining using soft relining material on the distribution of various occlusal forces using T-Scan system. Fifty completely edentulous patients having their conventional complete dentures earlier fabricated and utilized were selected for this study. Patients were controlled diabetics, characterized by having their residual alveolar ridges moderately developed and lined with firm mucoperiosteum. Mandibular complete dentures were relined with soft denture liner and T-Scan device was used for occlusal force distribution measurement prior to denture relining and three months thereafter the relinning procedure. Results Comparison between occlusal forces percentages before and after denture relining revealed that occlusal forces percentages was significantly lower after denture relining in anterior area, significantly higher after denture relining in right posterior area, where it was insignificantly higher after relining in left posterior area. Conclusions Our findings revealed that the use of soft denture liner for mandibular complete denture relining significantly improved the occlusal load distribution.

Analysis of the Hardness of Soft Relining Materials for Removable Dentures

“…The complete denture retention could also be improved by applying different methods, nevertheless, soft denture liners and denture adhesives are other modalities that could improve complete denture retention giving proper balance occlusion and in consequence equal distribution of the occlusal forces. Soft lining materials can help to evenly distribute the biting loads transferred onto soft tissues during chewing and to relieve the mucosa from high mechanical stress [13][14][15].…”

Impact of Cerium Oxide Nanoparticles Incorporation on Water Sorption and Solubility of Acrylic-Based Denture Soft Lining Material

“…This choice is significant as it contributes to the durability and support of dentures by facilitating a close fit against the oral mucosa [3,4]. The redistribution of forces generated by functional and parafunctional motions over the denture's bearing surfaces can be mitigated by achieving a well-balanced occlusion [5,6]. Establishing individual recall intervals is necessary to ensure adequate maintenance, as changes in the prosthesis base are inevitable due to the progressive resorption of alveolar bone after tooth extraction [7].…”

Determination of occlusal connections in patients with congenital cleft lip and palate before and after their orthopedic rehabilitation

“…Presently, the objective criterion for evaluation of occlusion is the use of computerized occlusal analysis using T-Scan, which, however, has some reservations [9,10]. Most methods of occlusal connections registration allow obtaining qualitative and semi-quantitative characteristics [11,12].…”
