Purpose: Injectable Platelet Rich Fibrin (I-PRF) is an efficient method in periodontal wound healing and regenerating bone; thus, the purpose of the current research was to assess radiographic and clinical of I-PRF around the immediate dental implant in the esthetic zone with xenograft. Material and methods: Twelve patients with unrestorable tooth/teeth in the esthetic zone were selected. Patients were selected randomly and split into two groups; Group I (test group; n = 6) patients that received immediate implant placement using I-PRF and xenograft and Group II (control group; n = 6) patients that established immediate implant placement with xenograft only. Clinically, the pain was evaluated for each patient by using the visual analog scale (VAS). Assessment of healing progress was conducted by modified gingival index (MGI)and modified plaque index (MPI) at 1 st , 3 rd , and 6 th months after implant placement. Radiography, the assessment of osteointegration, can be conduct by bone density at 1 st and 6 th month after implant placement. Results: Regarding the change in both MPI and MGI, there was statistically a significant difference. The study group showed a higher Change than the control group. At 1,3 and 7 days, there was a statistically non-significant difference in mean VAS in the two groups P=0.18. Regarding Change in Bone Density, the study group showed a higher Change than the control group with a statistically significant difference(P=0.002). Conclusion: The use of I-PRF with immediate dental implant placement offers a new promising safe, compatible, and effective method for managing the healing process around immediate dental implants.
Aim: To evaluate the mini-locking plate system in management of body mandibular fracture. Patient and methods: Twenty patients were randomly classified into two equal groups. Group ( 1): (The study group): Ten patients were treated by open reduction and internal fixation using single 2.0mm locking plate and arch bar as a tension band maintained for 5 weeks. Group (2): (The control group) Ten patients received the same treatment as in group ( 1) but with single 2.0mm conventional plate. Follow-up was performed for 6 months and post-operative complications such as infection, wound dehiscence, neurosensory disturbances and malocclusion were recorded. Arch bar was removed after 5 weeks of surgery. Data regarding age, sex, and bone density at the fracture side during healing, bite force measurements at anterior, premolar and molar regions were collected, tabulated and statistically analyzed using IBM SPSS software package version 20.0.Results: Uneventful healing of all fractures treated with mini-locking plates and conventional plate system, with no cases of malunion, nonunion, infection, or malocclusion being observed through the follow up periods. There was statistically difference between both groups regarding the mean bone density one week, 1, 3 and 6 months post-operatively. Bite force recording showed increasing values at subsequent follow ups corresponding to the healing of the fracture in both groups. Conclusion:Bone density in group (1) was in an accelerated pattern and of higher value than that of group (2). Patients treated with locking plate screw system regain more bite force compared to those treated with conventional miniplate screw system.
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.
