Abstract: Objective: This article reports a case of a patient with severely worn tooth and abnormal occlusal relationship who underwent orthodontic-restorative treatment combined with occlusal resonstrucion. Diagnosis and treatment: The patient’s teeth were severely worn and the occlusal relationship was abnormal. After collecting preoperative information and patient wishes, clarifying the diagnosis and treatment, and obtaining his informed consent, the patient accepted combined orthodontic and restorative treatment. The patient underwent orthodontic treatment first, which aligned the dentition and harmonized the dental arch. However, due to the loss of tooth morphology, orthodontic treatment is unable to restore stable jaw position. Digital temporary restoration helped to stabilize the jaw relationship and to restore occlusal function. After adaptation for the jaw relationship, digital technology was utilized to accurately transfer the jaw relationship and perform the final restoration. Results: The patient’s dental function was reconstructed and the jaw relationship was stable, at the same time, the aesthetics of the face and teeth was improved. Conclusions: Functionally oriented, the orthodontic-restorative treatment combined with occlusal reconstruction and digital technology can play a role in stabilizing the jaw relationship in patients with tooth wear, ultimately reconstructing the oral and maxillofacial function and improving patient’s aesthetics.
