Surgical mandibulo maxillary fixation (MMF) is a proven method of stabilizing most maxillofacial fractures involving the maxilla and/or mandible . Different surgical options available for treating maxillofacial fractures include open reduction internal fixation (ORIF), open reduction, closed reduction, and orbital reconstruction. Treatment outcomes usually rely on the nature of injury, type of fracture, expertise of surgeon, and devices/technology used . Infection is the most commonly reported complication of surgical treatment. Other less common complications include malunion of fractures, malocclusion, and temporomandibular joint disorder .

MMF using circumdental wires and arch bars may often result in partial or absent dentition. Lengthy operative time, risk for glove puncture, and pain during removal are other drawbacks of these traditional techniques . On the other hand, MMF screws are easy to use, may cause fewer traumas, may pose lower risk for percutaneous and mucosal wire punctures, and reduce risk of needle-stick injury . Understanding the biomechanical demands related to their use, proper modifications in design and customized placement to reduce any potential morbidity, and image-guided preoperative planning would make the use of MMF screws more advantageous. MMF screws can represent as a viable alternative to fixation with arch bars. It offers reduced costs as there is a decreased need for secondary procedures . Iatrogenic injury to dental roots, one of the risks involved with MMF screws, can be reduced by an experienced surgeon . These screws also help in maintaining better oral hygiene than arch bars and produces acceptable malocclusion

Dental implants are a long term replacement of teeth that are positioned in the jawbone beneath the gums. “They are substitutes for the roots of missing teeth and act as an anchor for a replacement tooth, crown, or a set of replacement teeth” (Dominguez). Since these are implanted directly to the jawbone, the gum will need to heal first and when the post is connected to the original implant, that is when the artificial tooth will be mounted. The convenience of this technology is that the adjacent teeth do not need to be prepped or dealt with when replacing the missing teeth. When the implants are properly maintained, they can typically last a lifetime and it is recommended to always take better care of the tooth.
