Abstract
Background; Edentulous state of a patient can lead directly to impairment, functional limitation, physical, psychological, and social disability. Edentulism was found to have a significant effect on residual ridge resorption, which leads to a reduction in the height of alveolar bone and the size of the denture bearing area. Tooth supported over denture is a concept which improve the retention and stability of the final prosthesis significantly, and also maintain the proprioception. Bone is a dynamic tissue. The extraction of teeth results in the initiation of the bone resorption pattern. Here we are reporting a case with advantages of exploiting few remaining teeth to minimize alveolar ridge resorption and improvement of retention and support through using complete over denture which overcomes many problems encountered by conventional complete denture and removable partial denture patients.
Highlights
Edentulism is a debilitating condition and can be described as the “final marker of disease burden for oral health” [1]
The current prevalence of complete tooth loss patients has declined over the last decade, still edentulism remains a major disease worldwide, especially among older adults [2]
Oral consequences vary from the well-known residual ridge resorption to an impaired masticatory function, an unhealthy diet, social disability, and poor oral health quality of life
Summary
Edentulism is a debilitating condition and can be described as the “final marker of disease burden for oral health” [1]. The current prevalence of complete tooth loss patients has declined over the last decade, still edentulism remains a major disease worldwide, especially among older adults [2]. Comparing various treatment methods within each other, implants supported over dentures may be described as the first choice in well selected patients [10,11], while it can be considered an option for aesthetic long-term treatment for elderly patients [12,13] and is may not indicated for individuals with poor general health status. Rissin et al in 1978 compared masticatory performance in patients with natural dentition, complete denture and over denture. A timely planned roots supported overdenture has been a proven mainstay of preventive prosthodontics therapy as it attempts to conserve the few remaining natural teeth/roots and reducing alveolar bone resorption. A final maxillary impression was made using Zinc oxide impression material (Cavex Outline Eugenol impression paste- BV 2003 RW Haarlem, the Netherlands) and final mandibular impression was made using the regular body (Aquasil, Dentsply) .
