A Simplified Digital Workflow for the Treatment of Pediatric Mandibular Fractures Using Three-Dimensional (3D) Printed Cap Splint: A Case Report

Pediatric mandibular fracture needs special consideration by clinicians. The management of pediatric mandibular fracture differs from that in adults considering the presence of tooth germs and the potential for mandibular growth. One of the most common forms of conservative management for pediatric mandibular fractures is the use of cap splint along with circummandibular wiring. The conventional workflow prior to performing surgery with this technique is impression taking and dental model fabrication. Additionally, it is also recommended that mock surgery should be performed to achieve proper reduction before acrylic splint fabrication. However, these procedures are effortful and time consuming when performed under general anesthesia during surgery and require additional sedation if performed prior to surgery. The aim of this case report is to describe a simpler preoperative digital workflow for the treatment of pediatric mandibular fractures, in which closed reduction is achieved with a three-dimensional printed cap splint stabilized with circummandibular wiring under general anesthesia.

Mandibular fractures are less common in children compared to adults, due to a number of factors including the anatomical complexity of mandibular development in a child. This article aims to discuss the treatment’s principle of mandibular fractures differ from that of adults due to concerns regarding mandibular growth and development of dentition. A case of a 7-year old boy with fracture of the left mandibular corpus that sinistra region was treated with a closed reduction method using gunning splints with circumferential mandibular wires. On the sixth week after surgery, the circumferential mandibular wiring and splint were removed. From clinical examination there was no edema; no oral mucosal abnormalities were found; no teeth mobility; and no step displacement at corpus mandibular sinistra region. The treatment’s goal is to restore the structures from the broken bone to its pre-injury position as non-invasively as possible with minimal residual esthetic and functional impairment.

Mandibular fractures lead to changes in occlusion, aesthetic deformities and functional alterations, when untreated, their sequelae may cause permanent problems, leading to a more complex treatment than the acute trauma. The treatment offers challenges that can be minimized with the aid of biomodels, printed by 3D technology. This article aims to report a biomodel-assisted surgical procedure for mandibular reconstruction, arguing how these prototypes may help to achieve better outcomes. The patient was involved in an automobile accident and sought treatment for the sequelae of mandibular fractures two years after the initial trauma. The biomodel printing of her mandible allowed for the execution of surgery on the model, reestablishing correct occlusion and facial aesthetics, and helping shorten the surgical time through the pre-bending of reconstruction plates. The patient improved uneventfully. The use of biomodels must be encouraged, especially in cases where the patient shows sequelae, when the anatomical landmarks are compromised, they offer more predictability for treatment outcomes, as described on this case report.

Modeling Data

The amount of photopolymer material consumed during the three-dimensional (3D) printing of a dental model varies with the volume and internal structure of the modeling data. This study analyzed how the internal structure and the presence of a cross-arch plate influence the accuracy of a 3D printed dental model. The model was designed with a U-shaped arch and the palate removed (Group U) or a cross-arch plate attached to the palate area (Group P), and the internal structure was divided into five types. The trueness and precision were analyzed for accuracy comparisons of the 3D printed models. Two-way ANOVA of the trueness revealed that the accuracy was 135.2 ± 26.3 µm (mean ± SD) in Group U and 85.6 ± 13.1 µm in Group P. Regarding the internal structure, the accuracy was 143.1 ± 46.8 µm in the 1.5 mm-thick shell group, which improved to 111.1 ± 31.9 µm and 106.7 ± 26.3 µm in the roughly filled and fully filled models, respectively. The precision was 70.3 ± 19.1 µm in Group U and 65.0 ± 8.8 µm in Group P. The results of this study suggest that a cross-arch plate is necessary for the accurate production of a model using 3D printing regardless of its internal structure. In Group U, the error during the printing process was higher for the hollowed models.

The rise of three-dimensional (3D) printing technology has changed the face of dentistry over the past decade. 3D printing is a versatile technique that allows the fabrication of fully automated, tailor-made treatment plans, thereby delivering personalized dental devices and aids to the patients. It is highly efficient, reproducible, and provides fast and accurate results in an affordable manner. With persistent efforts among dentists for refining their practice, dental clinics are now acclimatizing from conventional treatment methods to a fully digital workflow to treat their patients. Apart from its clinical success, 3D printing techniques are now employed in developing haptic simulators, precise models for dental education, including patient awareness. In this narrative review, we discuss the evolution and current trends in 3D printing applications among various areas of dentistry. We aim to focus on the process of the digital workflow used in the clinical diagnosis of different dental conditions and how they are transferred from laboratories to clinics. A brief outlook on the most recent manufacturing methods of 3D printed objects and their current and future implications are also discussed.

Intermaxillary Fixation

Background: Mandible is one of the commonly fractured bone due to trauma, assault and falls. Treatment includes closed and open methods. Methods of open reduction and internal fixation have changed and diversified enormously in the past few years. Champy’s miniplate fixation, dynamic compression plating has become a standard approach. More recently, three dimensional miniplates have been developed by Farmand which may be effectively used in mandibular fractures. The aim of this study was to check the adequacy of three dimensional miniplate in management of mandibular fracture occurring in the interforaminal region. Methods: A prospective clinical study was carried out in patients attending Emergency Department and Department of Oral and Maxillofacial Surgery, Nobel Medical College and Teaching Hospital (NMCTH) suffering from mandibular fractures in interforaminal region from May 2018 to January 2019. Results: A total of 17 patients with 18 fracture in interforaminal region, all male were included in the study. The age ranged from 16 to 50 years with a mean of 29.17 ± 9.48. Road traffic accident was the leading cause of injury with 15 out of 17 patients (88.23%). There was no incidence of wound infection, wound dehiscence, malunion, nonunion, plate fracture within the follow up period of 3 months. One fracture was unstable on 1st postoperative day and also had mildly deranged occlusion which was managed with intermaxillary fixation for two weeks. Conclusions: Three dimensional plates fulfills the treatment goals of adequate stabilization and fixation of mandibular interforaminal fractures.

Introduction. Frequency of pediatric mandibular fractures is relatively uncommon. Apart from rare exceptions, there is minimal invasive access in the treatment of those injuries in order to avoid the future developmental disorders. Case report. During the game with a colt, a 6-year-old boy was kicked by hoof in the chin. The child did not lose consciousness and did not experience nausea or vomiting. According to clinical examination and radiological analysis, diagnosis was assigned as dislocated mandibular fracture in the parasymphysis part of the jaw and luxation injury of teeth 31 and 72. The surgical treatment under general anesthesia encompassed reduction and bimanual manipulation of bone fragments up to the optimal restoration of the dental occlusion, along with osteosynthesis with titanium miniplates. Luxated deciduous tooth 72 at the fracture line was extracted and luxated permanent tooth 31 was fixed to tooth 41 with wire. The patient was given antibiotic therapy. Additional immobilization of the luxated tooth 31 and mandibular fracture was performed after surgery by composite resin splint. During five-month follow-up period there were no signs of pathological movements in the fracture line, no luxation of tooth 31 and no restriction in mouth opening. Conclusion. Osteosynthesis with miniplates is adequate and very efficient treatment method in dislocated mandibular fracture that is recommended in children with both deciduous and mixed dentition. It is necessary to remove miniplates after fracture consolidation.

AbstractTrauma induced maxillofacial injuries may affect function as well as estheticsin children. In hospitalized paediatric trauma patients, mandibular fractures are the most common. Boys are affected twice than girls. In children, management of mandibular fractures differ somewhat from that in adults. The objective of treatment is to restore the underlying bony architecture in a stable and non invasive fashion to pre injury position. Closed reduction method is preferred in most paediatric cases. This case report demonstrates the use of fabricated acrylic splint in the stabilization and fixation of a mandibular body fracture in a 5 yr old patient.

Distant metastasis to the jaws, including the maxilla or mandible, is very rare. Although the mandible is the preferred sight of these rare metastases, it is extremely rare for oral cavity malignancies to present as pathological mandibular fractures. Here, we present a case of esophageal adenocarcinoma metastasizing to the mandible, and the first reported case presenting with a pathological mandibular fracture secondary to esophageal adenocarcinoma. We also review the 9 other reported cases of metastatic esophageal adenocarcinoma to either the maxilla or mandible.
