Evaluation the mobility of the dental implant (comparison between the cemented and screw retained single fixed prosthesis


Aim of the study: To evaluate the mobility of the dental implant at the time of loading, after three months and six months from the loading of the implants in the patient's mouth of two types of retaining methods (cemented and screw type). Materials and Methods: A total of twenty dental implants were implanted in 20patients. These patients divided into 2 groups. The first group received screw retained prosthesis. The second group received cemented retained prosthesis. The stability of these implants was measured using periotest device at the time of loading, 3monthes and six months after loading. The data was analyzed using descriptive statistic, Analysis of variance (ANOVA), Duncan Multiple analysis range test and student t-test. Result: Among the two groups, the group receiving screw retaining prosthesis having a significant greater stability than that group receiving cemented type retaining prosthesis. Conclusion: the residual dental cement that remain after cementation of the cemented retaining prosthesis, affect directly on the perodontium health, and this subsequently affect on the stability of the dental implant.
