Abstract
Purpose: This in vivo study compared the clinical and radiographic outcomes of the mini-implant-supported overdenture and conventional implant-supported overdenture. The objectives of the study were to evaluate the pocket depth, crestal bone loss, and implant stability using a periotest and to measure patient satisfaction based on the oral health impact profile EDENT questionnaire in conventional and mini-implants supported overdentures.
Materials and Methods: One hundred and seventy-four subjects above 40 years of age were recruited and randomized into two groups on a 1:1 basis: Group 1-mini-implant supported overdentures (2.5 mm diameter×11 mm length) and Group 2-conventional implant-supported overdentures (3.3 mm diameter×11 mm length). Crestal bone loss was measured from the baseline to 12 months and from 12 to 36 months. The pocket depth and implant stability using a Perio test device were measured at 12 months and 36 months. Finally, the patient satisfaction based on the oral health impact profile EDENT questionnaire in conventional and mini-implants supported overdentures was recorded.
Results: There was no significant difference (P<0.05) in the pocket depth and crestal bone loss between the groups at 12 months and 36 months. Similarly, there was no significant difference in the perio-test values between the groups at 12 and 36 months. No significant (P<0.05) differences in physical pain, psychological discomfort, and disability were noted.
Conclusions: Both conventional and mini-implant-supported overdentures have similar outcomes with respect to the pocket depth, crestal bone loss, implant stability, and overall quality of life of the patient.
