Summary
Modified Widman flap (MWF) surgery does not decrease maximum bite force (MBF) in patients. Bite force typically returns to baseline levels within four weeks post-surgery, offering functional preservation.
Area of Science:
- Periodontal surgery
- Biomechanical analysis
- Patient function assessment
Background:
- Periodontal disease necessitates surgical intervention to preserve dentition.
- Assessing patient function post-treatment is crucial for evaluating surgical outcomes.
- Maximum bite force (MBF) serves as a key indicator of oral function.
Purpose of the Study:
- To evaluate the impact of modified Widman flap (MWF) surgery on maximum bite force (MBF).
- To determine if periodontal treatment affects a patient's chewing ability and oral function.
Main Methods:
- A clinical trial involving 24 patients undergoing MWF surgery.
- MBF was measured pre-operatively and at one, four, and eight weeks post-surgery.
- Repeated measures ANOVA was used for statistical analysis with a significance level of 0.05.
Main Results:
- Males exhibited significantly higher MBF than females.
- A significant difference in MBF was observed across the four time points (P<0.001).
- MBF showed a slight increase in males and a decrease in females over time, with no significant difference from baseline at four and eight weeks (P=0.148).
Conclusions:
- MWF surgery does not lead to a long-term decrease in MBF, providing reassurance for patients.
- The procedure is recommended for tooth preservation, a critical factor for maintaining MBF.
- Surgical outcomes regarding MBF appear more favorable in male patients, with baseline bite force typically regained by four weeks post-operation.
