Abstract

Background: The objective was the comparison effectiveness and evaluate the
postoperative complications of locking and conventional mini plates in mandibular
trauma.
Materials and Methods: The study group in this investigation consisted of 10 treated
patients who presented to the Department of Oral and Maxillofacial Surgery, St.Joseph
Dental College, Eluru for Open reduction and rigid internal fixation of mandible. The
mean age was 20-30 years, the case of injury and type of injury, since how many days of
injury were evaluated.
Results: Total of 20 patients have met the inclusion criteria in our study there are
changes in pain, swelling, paresthesia , infection of the site of fixation. In locking plates
there is subside of pain and swelling after 3rd week, we found difference between 1st
week, 3rd week and 6th week but pain was present till 6th week in conversional
miniplates Pre-operative swelling was present only in case of non-locking group.
Swelling was present in 60% of non-locking group and 0% in locking group. After one
week swelling was absent in 100% patients at 1rd, 3rd and 6th week. Swelling was
considerably decreased in locking group as compared to the non-locking group.
Conclusion: Our findings in our study conclude that locking plates have enough
stability, good adaptive capacity and withstand the masticatory forces in mandible and
clinical results almost similar to those seen with non-locking plate osteosynthesis.
