Herbert Screw vs Lag Screw Fixation in Anterior Mandibular Fracture Treatment

Comparative Study of Herbert Screw vs Lag Screw Fixation in Anterior Mandibular Fracture Treatment (a Clinical and Radiographic Study)

14 patients having recent anterior mandibular fracture divided into two groups. Group A has 6 patients and treated using Herbert bone screw, and group B has 6 patients and treated using lag screw.

Clinical follow-up was conducted after 24-hours, one, four, six, and twelve weeks. In addition, a radiographic investigation was performed after twelve weeks to estimate the mean bone density across the fracture line.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Herbert screw	Other: Herbert screw; Fracture line exposed through intra-oral approach. bone reduction into proper anatomical occlusion and application of Herbert screw

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Change in bone density	By using digital orthopantomogram bone density was evaluated	baseline and 3 months
change in pain scores	assessed through a 10-point Visual Analogue Scale (VAS). (0-1= None, 2-4= Mild, 5-7= Moderate, 8-10= Severe)	24 hours, 1 week , 4 Weeks and 6 weeks
presence of Intra-fragmentary mobility	assessed by bi-manual palpation across the fracture site	24 hours
