A comparative study between traditional fixation with miniplates and modified lag screws for the treatment of mandibular fractures

Abstract

The modified screw technique is a safe tool that does not require any specific osteosynthesis materials not found in a basic traumatology kit and has a lower cost, due to the reduced amount of material used.

Comparison of lag-screw versus miniplate for osteosynthesis of anterior mandibular fracture: A Randomized Control study

“…(14,25) In this work Fracture primary stability was achieved in both groups in contrary with another work in which lag screw fixation achieve primary stability than miniplate group and some investigators reported that increasing stability is related to increasing the number of screws. (12) The mouth opening was improved gradually in both groups and non of the patients had prolonged malocclusion. This is attributed to stable intraoperative intramaxillary fixation, excellent adaptation of plates, drilling the holes perpendicular to the fracture lines in cases of using lag screws, and verification of meticulous anatomic reduction of the fracture segments as recommended (26) .…”

Fixation of Mandibular Fractures with Lag Screw: Integrative Review

“…Other classifications of fractures distinguish them as simple or closed, compound or open, comminuted, greenstick, complicated or complex (12,13) . In addition, fractures can be: without displacement or without change in axis and complete bone contact along the fracture line; with deviation or change in axis and without bone contact and with interfragmentary failure; or with minimal or no contact between the fragments, presenting a defect or local bone loss (14) . The tension and compression pattern varies depending on where the force is applied to the jaw.…”

“…Elsayed et al treated mandibular angle fractures with only one lag screw fixed on the upper edge of the mandible or tension zone, and found greater stability interfragmentary compared to the groups treated with miniplates (16) . Carricondo et al treated mandibular fractures using the modified lag screw in the mandible base region (compression zone) and a miniplate in the alveolar base region (tension zone) and observed a faster healing in the region (14) .…”

“…The plate fixation system has gone through successive modifications, from the unfavorable lower border application, and the distracted buccal surface fixation, to the open reduction and internal fixation utilizing plates [9] . This latter procedure has become a widely recommended practice while in contrast to orthopedic surgery, lag screws become indispensable in maxillofacial osteosynthesis [10] . For lag screw not only immobilize the fractured parts but also provide a continuous compression on the fracture region [10,11] .…”
