Zygomatic implants have become a predictable treatment modality for the rehabilitation of the severely atrophic maxilla. Due to differing anatomic variations, proximity to vital anatomic structures and limited intraoperative visibility, the placement of zygomatic implants can be a difficult task; compromised implant positioning may ultimately lead to post-operative surgical and prosthetic complications. The purpose of this report is to demonstrate a technique that allows for the transfer of the sinus slot position. Ultimately, this optimizes zygomatic implant axis trajectory from preoperative prosthetic planning by using cone beam computed tomography (CBCT) and 3-dimensional (3D) planning software to fabricate a stereolithographic 3D-printed surgical guide.

Secondary reconstruction of posttraumatic facial deformities has been consistently described as one of the most challenging procedures performed. Ideal primary reconstruction cannot always be achieved, and often it is complicated by severe comminution or inadequate surgical management. It also can arise because of a lack of definitive surgical repair or excessive delay of initial treatment. Complications leading to secondary deformities can occur even when craniofacial injuries are treated by experienced surgeons. Following proper surgical principles, meticulous perioperative planning, and anticipation of potential functional and aesthetic sequelae limit many of those complications. Herein, we discuss secondary procedures in traumatic midface injuries.

Traumatic dental injuries affect 1 to 3% of the population, and disproportionately affect children and adolescents. The management of these injuries incorporates the age of patients, as children between 6 and 13 years of age have a mixed dentition. This helps to preserve the vitality of teeth that may be salvaged after a traumatic event. The clinical examination of these cases involves a thorough examination of the maxilla and mandible for associated fractures and any lodged debris and dislodged teeth or tooth fragments. The objective is to rule out any accidental aspiration or displacement into the nose, sinuses, or soft tissue. After ruling out any complications, the focus is on determining the type of injury to the tooth or teeth involved. These include clinical examination for any color change in the teeth, mobility testing, and testing for pulp vitality. Radiographic evaluation using periapical, occlusal, panoramic radiographs, and cone beam computed tomography is performed to view the effect of trauma on the tooth, root, periodontal ligament, and adjoining bone. The most commonly used classification system for dental trauma is Andreasen’s classification and is applied to both deciduous and permanent teeth. Managing dental trauma is based on the type of injury, such as hard tissue and pulp injuries, injuries to periodontal tissue, injuries of the supporting bone, and injuries of the gingiva and oral mucosa. Hard-tissue injuries without the involvement of the pulp typically require restoration only. Any pulp involvement may require endodontic treatment. Fractures involving the alveolar bone or luxation of the tooth require stabilization which is typically achieved with flexible splints. The most common procedures employed in managing dental injuries include root canal/endodontics, surgical tooth repositioning, and flexible splinting. Recognition and treatment of these injuries are necessary to facilitate proper healing and salvage of a patient’s natural dentition, reducing future complications to patients.

Mandibular fractures are the most common facial fractures that need surgical intervention. If untreated, these fractures affect a patient’s occlusion, degree of mouth opening, and facial symmetry, and could cause infection with significant pain. The goal of any surgical intervention is to restore the preinjury occlusion, even if the preinjury occlusion is abnormal. Initial therapies, whether surgical or conservative, are not always successful, however, and revision or delayed surgical intervention can be challenging. Herein, we review common causes of failure of primary surgical management of mandibular fractures and provide tips to successful secondary intervention.
