Overdenture retained by teeth using a definitive denture base technique: a case report.

This paper presents a technique involving the use of a definitive denture base to make overdentures. Cores with ball attachments were cemented over remaining lower teeth. Impressions of the edentulous maxilla and mandible were taken to obtain a definitive acrylic resin base. The definitive base of the mandible was perforated at the location of ball attachments and its female components were fixed to the base using acrylic resin directly in the patient's mouth. Wax rims were then made, jaw relationships recorded, teeth mounted and tried in, and the dentures were cured. This technique allowed for easy fixing of female components and better retention during the recording of jaw relationships, and can also be used in the construction of implant retained dentures.

Self-reported denture hygiene of a sample of edentulous attendees at a University dental clinic and the relationship to the condition of the oral tissues.

OBJECTIVES: This article aims to evaluate the habits of hygiene and usage of a sample group of Brazilian wearers of complete dentures. DESIGN: This study has a cross-sectional design. SETTING: It was performed in the dental clinic of the University of Mogi das Cruzes. SUBJECTS: A sample group of 236 complete denture wearers was selected. INTERVENTION: The individuals were interviewed and clinically examined. MAIN OUTCOME MEASURES: Most commonly used hygiene habits were assessed and recorded. Possible relationships between habits and oral conditions were also assessed. RESULTS: Dental treatment was sought by 43.6 % 10 years after their last dental appointment, 77.5 % declared they had been given no instructions regarding the hygiene of their dentures, only 22.9% said they had been instructed about oral hygiene, and 91.9% stated they had not been told to return for periodical review visits. Denture stomatitis was found in 42.4%, although 89% of these patients presented with no symptoms; 98.7% of the group brushed their dentures; 27.1% regularly immersed their dentures in chemical products; 26.3% removed their dentures overnight. A positive relationship was observed between the lack of recommendations regarding oral and denture cleansing and the presence of denture-related stomatitis and hyperplasia. Family income and periodicity of visits to the dentist were also found to be related. CONCLUSION: Mechanical cleaning is the most prevalent method of hygiene. Self-reported lack of guidance to oral care was statistically related to inflammatory oral conditions. Future research is necessary to clarify possible causal role between these factors.
