A case of occlusal reconstruction for bite collapse patient by utilizing the provisional restoration

Abstract

Objective: In the present study, we achieved a good outcome in restoring the occlusion of a patient with multiple missing teeth by examining mandibular function and position to determine the vertical dimension of occlusion (VDO) and then restoring occlusion using a provisional restoration. Methods: The patient was a 61-year-old man who visited our facility with a chief complaint of difficulty with chewing. The patient had no vertical stop due multiple missing molars and was only able to bite or chew with his anterior teeth while irregularity was also seen in his anterior coupling. After extracting the teeth with poor prognosis and completing initial treatment, we fabricated the provisional restoration after determining the patient's centric relation using a gothic arch to examine mandibular position including mandibular function. After a follow-up duration and confirming stability, we fitted the final prosthesis. Results: We succeeded in restoring proper centric relation and masticatory function. Discussion and Conclusion: Determining centric relation and achieving stability with a provisional restoration before fitting of the final prosthesis lead to a desirable treatment outcome and successful restoration of occlusion.
