Application of CAD/CAM technology for surgical treatment of condylar head fractures: A preliminary study

Management of the condylar head fractures is still one of the most controversial issues of the maxillofacial surgery. The aim of the present study was to increase the accuracy and quality of the surgical treatment of condylar head fracture with the use of navigation surgical guide and patient specific reinforcement two-component plate and individualized fixator with the use of CAD/CAM technology. In study was included 8 patient with 10 condylar head fractured. In 5 cases was used navigation guides, in 4 cases (the biomechanical unfavorable) was used the patient specific two-component plate and only in one case we used individualized patient specific plate. A CT scan was done immediately after the operation. The reduction of the fragments and the location of the screws, plate and fixator were checked on the same view in the preoperative and postoperative pictures on the computer. The relation between the screw and the cortical bones was clearly shown on CT, and the sizes of the bicortical screws were suitable with no injury to the articular cartilage or surrounding tissue. The three-dimensional objects showed that the screw was in the designated position and the condyle had been replaced and fixed in the normal position. The height of the ramus on the fractured side was restored immediately postoperatively. The malocclusion was corrected and the passive mouth opening of each patient was never less than 3 cm. One patients had transient paralysis of the temporal branch of the facial nerve postoperatively, which gradually recovered within a 2 month. Postoperative clinical examination showed good occlusion and mouth opening of at least 3 cm in all patients after 3 months without pain. All patients regained normal mandibular movements and had short and invisible scars at 6 months’ follow-up. Given the small number of patients, this issue needs further study in randomized prospective studies involving more patients and evaluating long-term postoperative outcomes

Purpose: The aim of the paper is to present the methodology of computer aided designingand manufacturing of an all-ceramic multi-unit bridge restoring missing teeth and the lostsoft and hard tissues of the oral cavity as a result of surgical treatment of oral tumor.Design/methodology/approach: The methodology of computer aided designing andmanufacturing of the multi-unit all-ceramic bridge was presented on the basis of an actualclinical case of a patient who underwent the surgical treatment of myxoma of the oral cavity.All the steps of clinical and technical production of the bridge were described and illustrated.Findings: It is possible to use the CAD/CAM technology to design and manufactureall-ceramic multi-unit bridges restoring missing teeth and the lost soft and hard tissues ofthe oral cavity. The design of the bridge must be clinically validated using mock-ups and onlythen can be implemented for the CAM software.Practical implications: Thanks to the method of designing and manufacturing of multiunitall-ceramic bridges for patients with significant lost of the soft and hard tissues of themouth it is possible to carry out a prosthetic rehabilitation of patients after trauma and tumorsurgery.Originality/value: : The execution of extensive bridges with the maximum available heightof about 25 mm requires a high technological rigor at the design and manufacture stage. Toensure longevity of the reconstruction, it is necessary to plan all the work while maintainingthe maximum thickness of the substructure. It is desirable to provide minimum of 2 mmthick substructure and the surface of at least 20 mm2 or more in the cross-sections. At thesame time, the structure of the bridge must be supported on the alveolar ridge to provideaesthetics and endurance.

Preliminary Study

Searching for new materials for bone substitution, fixation, and reconstruction is a challenging task that attracts scientists and researchers of different fields of medicine. During the last few decades, much interest has been paid to polymeric materials, polyethylene in particular. The aim of this study is to present generalizations about our own experience in the employment of polyethylene miniplates for the surgical treatment of mandibular fractures. Ninety patients with 139 uni- and bilateral mandibular fractures in different locations were involved. Treatment modalities included open reduction and internal fixation with self-made polyethylene miniplates of straight, T-shaped, Y-shaped, and X-shaped configurations and titanium screws. In 88 (97.8%) cases of surgical treatment of mandibular fractures using polymer miniplates, good anatomical and functional results were achieved. Regardless of the necessity for improvement of some mechanical properties of polyethylene, the results obtained in our clinical investigation allow us to recommend polyethylene miniplates for routine practice.
