Filter by:Using autogenous Chin block for vertical augmentation with simultaneous implant placement at anterior maxilla region comparing between the Onlay and Inlay grafting techniques.
Using bone ring grafts with simultaneous implant placement after three-dimensional augmentation of severely defective bone ridges using computer-guided surgical templates. The study compares accuracy effectiveness by mimics software
The purpose of this study is to determine if the injection of Platelet-rich plasma (PRP) is effective in reducing alveolar bone loss that happens after each rapid maxillary expansion (RME) on the buccal aspect of the posterior teeth. 16 patients with a skeletal maxillary constriction aged between 10-16 years old will get into orthodontic treatment to widen the maxilla using Hyrax appliance. An amount of patient blood will be withdrawn and centrifuged to get PRP. Then the PRP will be injected in one half of each patient mouth in a split-mouth design, beneath the buccal periosteal of the first molars and first premolars, the halves will be chosen randomly. High resolution CBCT images will be taken before and after orthodontic treatment to analyze buccal bone thickness and height changes.
To investigate the residual ridge resorption at anterior and posterior maxillary and posterior mandibular ridges among conventional complete dentures and implant overdenture wearers, and determine its association with the relative occlusal forces distribution, treatment groups and other patient variables.
Using growth factors obtained from patient's venous blood mixed with particulate autogenous bone the study compares bone gain by implant with gold standards in sinus Lift procedures for future implant insertion.

Background: Platelet-rich fibrin (PRF) and bioactive glass putty has been shown to be effective in promoting reduction in probing depth, gain in clinical attachment, and defect fill in intrabony periodontal defects. The individual role played by bioactive glass putty in combination with PRF is yet to be elucidated. AIM: To compare the clinical effectiveness of the combination of Plaltelet Rich Fibrin and Bioactive Glass Putty and Bioactive glass putty regenerative techniques for intrabony defects in humans. Material and methods: Ten pairs of intrabony defects were surgically treated with PRF and Bioactive glass putty (Test group) on one side or bioactive glass putty (Control group) on other side. The primary outcomes of the study included changes in probing depth, attachment level and bone fill of Osseous defect. The clinical parameters were recorded at baseline, 3, 6, and 9 months. Radiographic assessment was done using standardized intra oral periapical radiographs. Comparisions were made within each group between baseline, 3 months, 6 months and 9 months using the ANOVA test followed by Bonferroni test.
The aim of this study is to evaluate the influence of superstructure material on crestal bone resorption and esthetic outcome of dental implants in patients with single missing tooth in the aesthetic zone.
An open, prospective, randomized, multicenter study focused on the ridge diminution in case of grafting of fresh extraction sockets with Bio-Oss Collagen, Bio-Gide (Geistlich Pharma, Wolhusen, Switzerland), placing Dentsply implants (Astra Tech System).
This is a two-year prospective randomized clinical study to to evaluate whether the gingival thickness and insertion depth of dental implants have any influence on marginal bone levels changes around platform switched implants.
