Evaluation and Correlation of Bite Force With Electromyography (EMG) Activity Before and After Rehabilitation of the First Molar With an Implant-Supported Prosthesis

Background Prevalence of tooth loss significantly increases as age advances. The permanent first molar is regarded as the key to proper occlusion and, thus, its loss causes significant deterioration of the functioning of the masticatory apparatus and overall stomatognathic system. It not only affects the occlusal integrity but also the activity of surrounding tissues and muscles. Aim and objectives To evaluate and correlate the maximum bite force (MBF) and electromyography (EMG) activity before and after 24 hours and two months of rehabilitation of the missing permanent first molar with single-implant crowns. Materials and methodology This observational, prospective in-vivo type of study was done on 10 patients receiving dental implants for missing molars. Results There was a significant correlation between bite force and EMG activity post-treatment. Conclusion Dental implant therapy can be very well utilized for the replacement of single missing teeth.
