Comparison of Two Different Types of Platelet Concentrate to Augment Bone Around Immediate Dental Implant

The goal of this clinial trial is to detect Which one of two different platelet concentrate bio-membrane (first or third generation) is better in terms of marginal bone level and bone density around immediate implants in esthetic zone using Cone beam computerized tomography The plasma rich in growth factor or concentrated growth factor? 20 patients with nonrestorable maxillary tooth in the esthetic zone, Subjects will be enrolled The study will use simple randomization to allocate patients into 2 groups, each group will be included 10 patients: Group A: (concentrated growth factor group) ten patients indicated for immediate implant in the maxillary anterior region (class II socket), will be a candidate for immediate implant placement with CGF combined with xenogeneic bone graft Group B: (platelet-rich in growth factor group) Ten patients who indicated immediate implant in the maxillary anterior region (class I or class II socket), will be a candidate for immediate implant placement with PRGF combined with xenogeneic bone graft.

Guided Lateral Sinus Lifting Using Autologous Serum Albumin/Platelet-Rich Fibrin

This research aimed to evaluate the effect of an autologous Alb-PRF on bone regeneration after lateral sinus lifting via 3D volumetric analysis. The null hypothesis of this research was that there would be no significant difference between the group that would be treated by lateral sinus lift and Alb-PRF application and that would be treated by lateral sinus lift with bone graft for bone regeneration.

Marginal Bone Loss Around Mandibular Implant-retaining Overdentures and Implant Supported Fixed Hybrid Prosthesis

Few if any studies have compared marginal bone loss (MBL) around implant-retaining overdentures (2 implants with locators) versus implant supported fixed hybrid prosthesis (over 4 implants) in the mandible.

Effect of Soft Tissue Augmentation With an Acellular Dermal Matrix in Marginal Bone Levels Around Implants

The main objective of this study is to evaluate the efficacy of an acellular dermal matrix membrane to increase the peri-implant soft tissue thickness and to reduce marginal bone loss during non-submerged implant placement, as compared with the standard protocol for implant placement. The test hypothesis is that placing an acellular dermal matrix membrane simultaneous to implant placement in the posterior mandible, will increase the soft tissue thickness and consequently reduce the marginal bone level changes. The study is designed as a doubled-blind, parallel groups, randomized clinical trial with a 1-year follow-up
