Objective: To assess the treatment success between locking and non-locking miniplates when used for the constructive repair of mandibular symphysis and parasymphysis fractures of the mandible.
Study Design and Setting: This study is designed as a quasi-experimental conducted in the Oral and Maxillofacial Surgery Department of Punjab Dental Hospital and De Montmorency College of Dentistry, Lahore.
Methodology: This quasi-experimental was conducted in the Oral and Maxillofacial Surgery Department of Punjab Dental Hospital and De Montmorency College of Dentistry, Lahore. It enrolled 60 patients into each group consisting of locking and non-locking variants for a total of 120 participants. The data was evaluated through SPSS version 25 by applying the Chi-square test and one-way ANOVA test.
Results: Fracture stability was achieved in of patients in the locking miniplate group compared to in the non-locking group, with statistical significance (p=0.040). The need for additional IMFs was significantly lower in the locking group, with only required additional fixation, compared to the non-locking group (p=0.00095). Pain scores, measured using the VAS, were significantly lower in the locking miniplate group compared to the non-locking group with a p-value of 0.0001. Soft tissue healing was significantly better in the locking group, showing proper healing compared to the non-locking group (p=0.008).
Conclusion: The superior locking miniplate design achieves better fracture stability through increased mechanical stability as well as reducing postoperative discomfort and improving the healing of soft tissue structures, thus establishing their advantage over traditional non-locking miniplate methods.
