A study to correlate the incidence of cross arch balance and working side occlusal wear facets among different age groups: An in vivo study

Abstract

From the study, it was observed that there was no significant variation in the number and extent of wear facets between the cross arch and without cross arch subjects due the smaller sample size hence it was difficult to conclude the relationship non-working side contact as interference and its influence in wearing of dentition in this study.

A study of change in occlusal contacts and force dynamics after fixed prosthetic treatment and after equilibration – Using Tekscan III

“…Effects produced by contacts on nonworking side during lateral excursions have been extensively studied. Earlier studies have reported signs and symptoms such as pain on mandibular movements, muscle tenderness to palpation,[17181920] tenderness to palpation of temporomandibular joints (TMJ),[20] pain on passive jaw opening,[20] tooth mobility, bone loss, pocket depth greater in teeth with nonworking side contacts,[21] symptoms of mandibular dysfunction,[22] increased electromyographic (EMG) activity of masseter and temporalis,[2324] bruxism,[2526] and reduced masticatory performance[27] as a result of contacts on nonworking side. Experimental study in monkeys showed that occlusal interferences caused increase in bone density at the condylar neck as measured by computed tomography scans.…”

Effect of artificial eccentric occlusal interferences on masticatory performance: A randomised double‐blind clinical trial

“…17,44 The results found in this study justify that creating larger interferences would be unnecessary, as sizes beyond the minimal disablement of the incisor and canine guide would very likely further reduce masticatory performance, in addition to risking the integrity of volunteers. [2][3][4]6,44 Larger increments of composite resin also establish premature deflective contacts during closure and abnormal centric slides, 8 which would affect the results.…”

“…Occlusal interference (OI) is defined as any tooth contact that inhibits the remaining occluding surfaces from achieving stable and harmonious contact 1 . These disturbances overload the antagonist surfaces of the teeth or conventional or implant restorations, leading to wear facets, 2 fracture 3 or mobility 4 due to continuous microtrauma; oro‐facial pain 5 ; and changes in muscle activity or mandibular movement patterns as an attempt to compensate for orthopaedic instability and improve function 6 . The sensorimotor cortex can also be affected, with the modification of brain activity depending on the strength of movement in the oral and maxillofacial areas 7 …”
