Aim:
This randomised clinical study aimed to detect whether CMLOC attachment could improve Oral Health-Related Quality of Life (OHRQOL) when compared to ball attachment.
Methods:
Eighty edentulous patients were recruited to receive a single symphyseal implant for mandibular overdenture, after three months, randomisation was done to divide them into two groups; Dalbo ball (control group) and Cendres and Metaux locator (CM-LOC) (intervention) attachments respectively, oral health impact profile for edentulous patients (OHIP-EDENT)questionnaire was recorded before implant placement, two weeks after pick up, at 3, 6, 9, and 12 months.
Results:
Results revealed a lack of statistical significance between the two groups except for psychological discomfort at 2 weeks after pick-up (p-value = 0.029).
Conclusion:
Single implant overdenture is a simple, reliable treatment modality for treating edentulous mandible and both CM LOC and Ball attachments are good alternatives for such treatment modality.
