“…Globally, the neuromuscular coordination during chewing in hemimandibulectomy patients was satisfactory as reported by several investigators (Gartner et al 2000; Haraguchi et al 2003), although some alterations were observed in the non‐operated side of mastication. Indeed, bone resection seems to affect muscle activities principally when the operated mandible plays a balancing role during chewing.…”

“…Bolus consistency characteristics are conveyed via periodontal receptors and mucosa in the oral cavity, which send a signal to the mandibular region of the primary cortex to initiate the appropriate masticatory force [43-45]. Electromyographic differences during maximal occlusal force tasks have been reported in edentulous patients fit with dental prostheses suggesting that changes in afferent feedback can influence masticatory muscle performance [46]. In the current study, the contribution and quality of afferent information may have changed over the course of the study as teeth emerged.…”

“…In addition, muscular work performance (bite-force ratio and muscle activity) was found to be lower in patients with implants [35]. Furthermore, less coordinated masticatory muscle activity was found in patients with implant-supported prostheses [36]. …”

Short-term follow-up of masticatory adaptation after rehabilitation with an immediately loaded implant-supported prosthesis: a pilot assessment

BackgroundWhen teeth are extracted, sensory function is decreased by a loss of periodontal ligament receptions. When replacing teeth by oral implants, one hopes to restore the sensory feedback pathway as such to allow for physiological implant integration and optimized oral function with implant-supported prostheses. What remains to be investigated is how to adapt to different oral rehabilitations.The purpose of this pilot study was to assess four aspects of masticatory adaptation after rehabilitation with an immediately loaded implant-supported prosthesis and to observe how each aspect will recover respectively.MethodsEight participants with complete dentures were enrolled. They received an implant-supported acrylic resin provisional bridge, 1 day after implant surgery. Masticatory adaptation was examined by assessing occlusal contact, approximate maximum bite force, masticatory efficiency of gum-like specimens, and food hardness perception.ResultsOcclusal contact and approximate maximum bite force were significantly increased 3 months after implant rehabilitation, with the bite force gradually building up to a 72% increase compared to baseline. Masticatory efficiency increased by 46% immediately after surgery, stabilizing at around 40% 3 months after implant rehabilitation. Hardness perception also improved, with a reduction of the error rate by 16% over time.ConclusionsThis assessment demonstrated masticatory adaptation immediately after implant rehabilitation with improvements noted up to 3 months after surgery and rehabilitation. It was also observed that, despite gradually improved bite force in all patients, masticatory efficiency and food hardness perception did not necessarily follow this tendency. The findings in this pilot may also be used to assess adaptation of oral function after implant rehabilitation by studying the combined outcome of four tests (occlusal contact, maximum bite force, masticatory efficiency, and food hardness perception).
