“…The cross over study design standardized patientbased factors that may affect EMG activity such as age, gender, muscle activity, muscle power, neuromuscular control, and ridge morphology 6 . It also allow the use of reduced patient sample since the same number of patients received different treatments 6 .…”

“…The skin over the muscles was cleaned with alcohol. Surface electrodes were placed on the bellies of the masseter muscle of the preferred chewing side of the patient 6 . The active electrodes were positioned on mid-longitudinal fibers of the muscle parallel, and the reference electrode was placed on the patient's forehead.…”

“…Electro conductive gel (Elefix, NIHON KOHDEN) was used on the electrode before fixing it to the skin using adhesive bandage tape. Each patient was instructed to clench on teeth without food and to clench on a sample (dimensions 3 × 1 × 1 cm) of hard (carrot) and soft (banana) foods 6 until the foods became ready for swallowing. Analysis of EMG signals was performed with programs of EMG equipment.…”

“…Implant insertion for edentulous patients have reported to contribute to the preservation of residual ridges, improvement of the masticatory parameters and patient satisfaction 3 . The use of implant supported over denture has excellent outcomes for the edentulous patients compared with the conventional dentures, due to reduced residual ridge resorption and improved retention and support of the prostheses 4 resulting in better quality of life function 5 , chewing and masticatory functions 6 , nutritional status and general health 7,8 .…”

Purpose: This study was conducted to compare the electromyographic [EMG] activity of both masseter and the anterior temporalis muscles in patients with: Conventional complete dentures, Implant supported overdentures without attachments and, Implant retained overdentures with locator attachments. Material and methods: Six completely edentulous male patients with atrophied mandibular ridges received upper and lower conventional complete denture. EMG activity were measured for both masseter and the anterior temporalis muscles during clenching without food, clenching hard (carrot) and soft (banana) foods. Measurements were made at time of denture insertion, one month and two months after. Two implants were installed in canine regions of the mandible. After osteointegration, healing abutments were connected and the mandibular denture were relined with hard acrylic resin. Measurements were repeated, then healing abutments were replaced with locator attachments, and measurements were repeated again. Results: The highest EMG activity/amplitude of masseter and temporalis muscles, were noted with locator overdentures, and the lowest values were observed with conventional dentures. There was no statistically difference in muscle activity between implant supported overdentures and complete dentures. For all groups, muscle activity for masseter and temporalis muscles increased with advance of time. For both groups, muscle activity was significantly higher during clenching of hard food than clenching without food or with soft food Conclusion: Within the scope of this study, implant retained overdentures are recommended for edentulous patients rather than conventional complete dentures or implant supported overdentures as it improves EMG activity/amplitude of masseter and temporalis muscles.

Objectives Single denture rehabilitated patients have negative appraisals regarding oral function, mostly associated by stability and retention issues regarding mandibular prosthetics. Therefore, this study assessed patients’ occlusal equilibration, muscle activity, and oral health-related quality of life (OHRQoL) receiving milled removable or fixed mandibular implant retained prostheses. Materials and methods Twenty-two edentulous mandibular ridges patients were randomly distributed into two groups based on the definitive prosthesis received. Group I: Removable mandibular implant-supported overdenture, Group II: Implant retained fixed prosthesis. Occlusal equilibration was evaluated utilizing Occlusense, muscle activity via Electromyograph (EMG) at delivery, after one, and three months. The OHRQoL was evaluated by Oral Health Impact Profile questionnaire (OHIP-19) before delivery and after follow-ups. Data were collected, tabulated, and analyzed, utilizing independent t-test and One-way ANOVA followed Tukey`s post-hoc test. Significance level set at P ≤ 0.05. Results Groups I &II showed significant improvement in occlusal equilibration, muscle activity and OHRQoL. Group II demonstrated significantly higher improvement than group I in occlusal equilibration associated with muscle activity after 1 month, and in functional limitations domain in OHRQoL questionnaire after 3 months. Conclusion Implant retained mandibular prosthesis showed improvement in occlusal equilibration, muscle activity, and OHRQoL regardless of prosthesis type employed. Fixed implant-supported prosthesis revealed better outcomes than removable mandibular implant-supported overdenture concerning occlusal equilibration, muscle activity, and OHRQoL regarding functional limitations. Clinical relevance Implant retained mandibular prosthesis is one of best treatment options for single mandibular completely edentulous patients, as dental implants improved occlusal equilibration, muscle activity, and OHRQoL.
