Summary
Implant-supported restorations do not alter an individual's preferred chewing side (PCS). Understanding PCS is crucial for planning implant restorations, ensuring better patient outcomes and treatment strategies.
Area of Science:
- Dental Implantology
- Oral Rehabilitation
- Human Physiology
Background:
- Chewing side preference (PCS) is a well-documented phenomenon.
- The influence of dental prosthetics, particularly implant-supported restorations, on PCS is not fully understood.
- Local effects from implants might theoretically alter established chewing patterns.
Purpose of the Study:
- To investigate if implant-supported restorations affect an individual's preferred chewing side (PCS).
- To determine the correlation between PCS and other laterality preferences (handedness, footedness, eyedness, earedness).
- To establish whether implant placement influences PCS distribution.
Main Methods:
- A comparative study involving 81 patients with partial implant-supported prostheses (test group) and 108 subjects without implants (control group).
- Assessment of preferred chewing side (PCS) using gum-chewing tasks, observing the initial chewing stroke.
- Laterality tests for hand, foot, eye, and ear preference were conducted.
- Phi correlation tests were performed to analyze the relationship between PCS and other laterality preferences.
Main Results:
- A significant positive correlation was found between PCS and handedness (r=0.54), footedness (r=0.49), eyedness (r=0.65), and earedness (r=0.66).
- The majority of subjects (78.3%) preferred the right side for chewing; 19.1% preferred the left.
- No statistically significant difference in PCS distribution was observed between genders, nor was it affected by the location of missing teeth or implants.
Conclusions:
- Implant placement does not statistically affect an individual's preferred chewing side (PCS).
- PCS is strongly correlated with other established laterality preferences.
- Incorporating PCS assessment into the routine preoperative examination for implant-supported restorations is recommended for optimized treatment planning.
