Purpose: Calcium channel-blocking agents are used extensively for the management of hypertension. Gingival overgrowth around natural teeth has been previously reported in the literature with patients taking calcium channel-blocking agents. There are limited scientific documentations illustrating its effects around dental implants. This study compared the effects of Calcium channelblocking agents (Amlodipine) and angiotensin receptor blockers (Valsartan) on dental implants retaining overdentures in hypertensive patients clinically and radiographically after two years of function. Materials and Methods: Twenty completely edentulous male hypertensive patients wearing mandibular overdentures retained by two implants (3.6*12mm Dentium Two-piece (Ball type) dental implant, Dentium Implant System, Korea) were included in this study, Patients were equally and randomly divided into two groups, Group (I) were managed by Amlodipine according to their physician to control the hypertension. Group (II) were managed by Valsartan according to their physician to control the hypertension. Each case was evaluated clinically concerning plaque index, gingival index, probing depth and implant stability by using OSSTELL ISQ and radiographically concerning marginal bone loss at baseline (overdenture insertion) and after 6, 12 and 24 months. Data were collected, tabulated and statistically analyzed using t-Student test. Results: No statistical significant difference was found between the two groups (P≥0.05). Conclusions: Based on the limitations of the present study and although no statistical difference was found between the effect of Amlodipine and Valsartan on dental implants under overdentures. Peridontium around implants in hypertensive patients managed by calcium channel blockers Amlodipine was affected more than that managed by Valsartan.
Purpose: This study was conducted to evaluate the effect of glycemic control on implants assisted mandibular overdentures in type II diabetic patients after three years of function. Materials and Methods: Thirty, completely edentulous patients with a mean age of fifty years old were included in this study. For each patient two implants (3.5*13mm Anyone Two-piece dental implant, Mega Gen Implant System, Korea) were placed at the canine region bilaterally with equator attachment to retain mandibular overdenture. Patients were distributed into two groups: Group (1) contained patients who their glycemic control values below 8%. Group (2) contained patients who their glycemic control values 8% or above 8%. Each patient was evaluated clinically concerning plaque index, probing depth and implant stability by using resonance frequency analysis and radiographically concerning marginal bone loss at baseline (overdenture insertion) and after 6, 12, 24, 36 months after insertion. Data were collected, tabulated and statistically analyzed using t-Student test.Results: There was a statistically significant difference between both groups (P < 0.05) regarding probing depth, implant stability and marginal bone loss Conclusions: Wither the limitations of this short term study, glycemic control seems to have an effect on the survival of implants assisted complete overdentures in type II diabetic patients.
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.
