Aim: It was to compare Locator versus ball and socket attachment systems for single implant retained mandibular overdenture in relation to retention and oral health related quality of life. Subjects and Methods: Twenty completely edentulous patients were randomly selected from the Outpatient Clinic. Patients were divided into two groups, group (I) received single implant retained overdenture with ball and socket attachment while group (II) received single implant retained overdenture with locator attachment. Retention was measured three months interval after overdenture insertion for one year using force gauge device. Oral healthrelated quality of life was evaluated using OHIP-EDENT questionnaire after one year of overdenture insertion. Results: Group (II) recorded higher retention values than group (I) and the difference was statistically significant. Group I recorded higher Oral healthrelated quality of life mean values than group II and the difference was statistically non-significant. Conclusion: Locator attachment significantly increases retention of implant retained overdenture than ball and socket attachment. There is no significant difference in Patient oral health and quality of life between locator and ball attachments.
Aim:The aim of this study was to radiographically evaluate ball versus locator attachment systems for mandibular single implant-retained complete over denture. Subjects and Methods: Twenty completely edentulous patients were randomly selected from the Outpatient Clinic, Department of Removable Prosthodontics, Faculty of Dental Medicine, (Boys, Cairo), Al-Azhar University. The patients divided into groups, group I received single implant retained overdenture with ball and socket while group II received single implant retained overdenture with locator attachment. Radiographic evaluation was carried out with periapical radiograph using the extension cone parallel technique. Results: Group I recorded higher bone loss than group after one year of overdenture insertion and the difference was significant. Conclusion: Locator attachment provides optimal results regarding preservation of bone around implant fixture of implant retained overdenture than those with ball and socket attachment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
