Summary
The All-on-Four dental implant treatment shows similar muscular function to natural teeth in edentulous patients. This oral rehabilitation option offers comparable functional benefits to having natural dentition.
Area of Science:
- Oral rehabilitation
- Implant dentistry
- Biomechanical analysis
Background:
- All-on-Four (Ao4) fixed implant-supported prostheses are common for edentulous patients.
- The functional outcomes of Ao4 therapy require further investigation.
Purpose of the Study:
- To evaluate the muscular function in patients rehabilitated with the All-on-Four concept.
Main Methods:
- Compared muscular activity via electromyography (EMG) in 63 patients: 21 Ao4, 21 dentate, and 21 complete denture wearers.
- EMG was recorded during clenching, chewing, and rest, with data standardized to maximum voluntary contraction.
Main Results:
- All groups exhibited symmetric muscular activity.
- Ao4 and dentate groups showed similar masseter and temporalis muscle activity patterns, unlike the denture group.
- No significant statistical differences were found between the Ao4 and dentate groups.
Conclusions:
- The muscular function of patients treated with All-on-Four is comparable to that of dentate individuals.
- The All-on-Four concept is a viable and effective option for oral rehabilitation in edentulous patients.
