Objective: The purpose of this article was to introduce a method for the digital application of three‐dimensional (3D) diagnosis and treatment with a virtual articulator and 3D data. Clinical Consideration: With the use of cone‐beam computed tomography (CBCT) and intraoral and facial scans, we can create a virtual articulator and evaluate the mandibular position in maximum intercuspation and centric‐related occlusion for the patient with an unstable occlusion and temporomandibular disorders (TMD). Based on this, we treated a case using a digital mandibular position indicator (MPI) and fabricated a stabilization splint using a 3D printer. This approach eliminates the traditional impression or model mounting process and the analog face bow transfer. Furthermore, the design of the stabilization splint is accomplished using software. Conclusions: The approach outlined in this article offers the potential for a digital diagnosis and treatment process by seamlessly integrating CBCT, intraoral scans, and facial scans with a high degree of accuracy. This may enhance precision in diagnosis and treatment planning, especially for patients with complicated TMD, in addition to facilitating effective communication with orthodontic patients who require thorough attention. Clinical Significance: Utilizing a virtual articulator and digital MPI for the occlusal evaluation of patients with TMD and unstable occlusion makes it possible to diagnose and analyze the occlusal condition accurately. This approach also allows for precision and efficiency in treatment. [ABSTRACT FROM AUTHOR]

The orthodontic treatment of patients having temporomandibular disorders are some of the most complicated cases to treat. The positions of the mandibular condyles are often unstable, which means clinicians find it difficult to have definite criteria for making an accurate and reliable orthodontic diagnosis. This article reports the orthodontic treatment of a patient showing skeletal Class II and temporomandibular disorders with condylar resorption. To stabilize her condylar position and to relieve her symptoms in the temporomandibular joint, a stabilization splint was used before orthodontic tooth movement. After the splint therapy, the patient exhibited significantly increased open bite and a more severe Class II occlusal relationship as her mandibular condyles were seated anteriorly and superiorly in the articular fossae. The occlusion and facial esthetics of the patient were improved by orthodontic camouflage treatment with the proper use of temporary skeletal anchorage devices and treatment mechanics.

A 23-year-old woman with condylar resorption and a skeletal Class II pattern and anterior open bite were treated with 4 premolar extractions and temporary skeletal anchorage devices in both maxillary and mandibular arches. Before the start of orthodontic treatment, her unstable condylar position was stabilized with a stabilization splint for 6 months. Sequential evaluation of her condylar position was performed using a mandibular position indicator. The total active orthodontic treatment time was 30 months. After treatment, her occlusion, soft tissue profile, and unstable jaw position were significantly improved. Posttreatment records after 36 months showed excellent results with a good, stable occlusion. [ABSTRACT FROM AUTHOR]
