Objectives: This study was conducted to assess and compare the effect of platelets rich fibrin (PRF) versus mineralized plasmatic matrix (MPM) as bone regenerative materials during immediate implant placement. Material and Methods: A total of 10 patients with 12 implants have been included in this study, patients were divided into 2 groups. Group I received Mineralized Plasmatic Matrix (MPM), and group II received Platelets Rich Fibrin (PRF) as bone regenerative materials for immediate implant placement. The treatment outcome was evaluated clinically and radiographically at 3 and 6 months of implant placement. Also bone height and bone density were measured radiographically preoperatively, immediate post operatively, at 3 and 6 months postoperatively and statistically analysed. Results: Statistical analysis showed that bone density increased significantly (p≤0.05) at 3, and 6 months postoperatively in both groups. By comparing the two groups, Group I had statistically significant (p≤0.05) higher bone density scores than Group II at all of the follow up intervals. Regarding the bone height, there was no statistically significant difference (P ≥ 0.05) between the two groups at all of the follow up intervals except that group I showed a statistically significant (P ≥ 0.05) higher mesial bone height level at 3and 6 months postoperatively accompanied by a statistically significant (P ≥ 0.05) higher distal bone level as well at 6 months postoperatively than that of group II. Conclusion: The use of MPM was more superior to PRF as bone regenerative material for immediate implant placement regarding bone height and bone density.
Objectives: This study was conducted to assess and compare the effect of autogenous bone graft versus mineralized plasmatic matrix (MPM) and versus the Nano hydroxyapatite bone graft as bone regenerative materials during immediate implant placement. Material and Methods:A total of 14 patients with 18 implants have been included in this study, patients were divided into 3 groups. Group I(control group) received autogenous bone graft. Group II (study group A) received Mineralized Plasmatic Matrix (MPM), and group III (study group B) received Nano hydroxyapatite as bone regenerative materials for immediate implant placement. The treatment outcome was evaluated clinically and radiographically at 3 and 6 months of implant placement. Implants stability was measured using Osstell radiofrequency device at 3 and 6 months postoperatively. Also bone density were measured radiographically at 2 weeks and at 3 and 6 months postoperatively and statistically analysed.Results: Statistical analysis of bone density measurements between the three groups showed significant difference (P ≤ 0.05) between the control autogenous bone group and the two other groups (MPM &Nano bone) at all time intervals. Comparison between the test groups revealed non-significant difference (P ≤ 0.05) between (MPM & Nano bone) at two weeks interval. While at three & six months postoperatively there was a significant difference (P ≤ 0.05 between the two groups. Regarding implant stability comparison between the three groups , there was no statistical significant difference between them (P ≤ 0.05) at three and six months post operatively. Conclusion:The autogenous bone graft remains the gold standard for grafting materials but the use of MPM and Nano hydroxyapatite grafting materials can also give successful results regarding implant stability and bone density.
Purpose: Mid-face injuries are usually accompanied with loss of integrity of the orbital skeleton along with the subsequent affection of the visual apparatus. This study aimed to highlight the incidence of different eye injuries associated with mid-facial fractures and to accentuate the need of the maxillofacial surgeon to comprehend and approach the post-traumatic ophthalmic consequences. Patients and methods: A total of twenty five patients suffering from mid-facial fractures and orbital involvement were included in this study from the departments of oral and maxillofacial surgery, faculties of Dentistry, Cairo University and MSA University. They were 22 males and 3 females with a mean age of 37 years. All the patients were subjected to immediate clinical and radiographic examination to evaluate the extent of the injury and its implications. An ophthalmologist was asked to further assess the eye apparatus to determine the exact ophthalmic complications. The collected clinical, radiographic and ophthalmic findings were recorded and analyzed. Results: A dominating etiology of Road Traffic Accidents was found (64%) with a significant male predominance (88%). Mid-face trauma in the form of ZMC fracture was acquainted as the most common reason for ophthalmic problems (36%) followed by the direct orbital blow-out fractures (20%). A wide range of ophthalmic complications were recorded. Sub-conjunctival hemorrhage (92%) was the most common to occur followed by peri-orbital edema (84%) and lid ecchymosis and laceration (76%). A clinical complaint from sensory infra-orbital nerve paresthesia was documented (72%). Diplopia (48%) and Enophthalmus (24%) were encountered as the most severe types of complications with other non-significant occurrence of reduced vision (8%), retinal detachment (4%), corneal problems (8%) and traumatic hyphema (8%). Conclusion: We concluded that it is a must to extend the maxillofacial surgeon's knowledge to include post-traumatic ocular injuries and their ophthalmic complications to complement an optimal patients' treatment outcome and to prevent disastrous ophthalmic repercussions following mid-face injuries.
