Dental aesthetics play an important role as it positively accesses the self-confidence, social life, and overall well-being of adults. 1 Dental carelessness in terms of daily oral hygiene practices, access to oral health resource, dietary habits of the patient and attitude toward oral health are associated with poor oral hygiene status, caries experience, and periodontal disease. 2 Severely debilitated oral conditions which involve the maximum number of teeth, demand for more extensive and multidisciplinary treatment. 3 Tooth wear can result from abrasion, attrition and erosion. Excessive occlusal wear is a combination of various processes and it rarely acts alone. 4 Proper diagnosis and treatment planning is needed for rehabilitating such case. Attention must be placed on parafunctional habits like bruxism, restoration and maintenances of a healthy dentition. 5 Aesthetic and functional rehabilitation of the worn-out dentition is always a significant clinical challenge. However, the rehabilitation of the severely worn dentition becomes more challenging when insufficient space for restoration is present. 6 This case report describes full mouth rehabilitation treatment of a patient of worn out dentition that presented with severe wear, who was clinically monitored to evaluate the adaptation to the removable occlusal splint during 2 and 4 weeks as trial period after raising vertical height to avoid further complications of treatment. Full mouth restoration of the severely worn teeth represents a significant clinical challenge to a Prosthodontist. Tooth wear has intrigued restorative dentists due to its multifactorial aetiology. Loss of tooth structure may occur through non-carious processes like abrasion, attrition, erosion and possibly abfractions, acting alone or in combination. This case report describes a 44-year-old male, who had unilateral headache from last two and half years. There was an aesthetically and functionally compromised tooth due to collapsed bite.
