Crestal Bone Changes Following Equi-crestal Versus Subcrestal Implant Placement

Statement of problem: The stability of peri-implant bone is a crucial factor for the long-term success of dental implants, where crestal bone plays a significant role in both the primary as well as the long- term implant stability. A bone loss of 1.5 mm during the first year of loading has been acceptable according to the early standards. However, more bone stability can be expected with the development in implant designs and surfaces over the past decades. Aim of the study: the aim of this study is to radiographically assess the crestal bone changes following delayed implant placement in mandibular previously augmented posterior sites, comparing cases with equicrestal implant placement with subcrestal implant placement

Healing After Augmentation of Alveolar Ridge Using Collagen Membrane

One of the prerequisites for successful prosthetic implant therapy of patients is achieving the initial stability of the embedded implant, which largely depends on the width alveolar ridge, at the place of its installation. Regenerative therapy of the horizontal dimension of the alveolar ridge simultaneously with the installation of implants is carried out using biocompatible materials; a basket of thin ones substitutes and collagen membranes. Clinical application of the collagen matrix to date has shown successful regeneration soft tissue in corrective surgery of the oral mucosa, by increasing the volume of the gingiva, approximately as effective as the application of a connective tissue graft from the palate. In the current literature, there is no data on the cellular effects of the regeneration of soft, a especially bone tissue, after the application of a membrane with cross-linked collagen type I, u regenerative therapy of fenestrations, dehiscence and buccal contour augmentations bone lamellae, simultaneously with implant placement. Also, tissue monitoring mechanisms of regeneration of soft and bone tissue, has not been shown in the literature so far controlled and systematized results using the Primescan digital program scans and software analysis of soft tissue regeneration parameters, as well as their own correlations with CBCT and clinical analysis.

Evaluation of the Bone Volume in Horizontal Atrophic Ridges Augmentation Using Tenting Grafting Technique Versus Khoury Technique in Mandibular Molar and Premolar Region: Randomized Clinical Trial

The aim of this study is to compare the effectiveness of the Tenting Grafting Technique and the Khoury Technique for horizontal augmentation of atrophic alveolar ridges in mandibular molar and premolar regions in dental implant procedures. Hypothesis: We hypothesis that the tenting grafting technique is more effective for augmenting atrophic ridges with horizontal bone deficiency, whereas the Khoury technique will yield superior results for severely atrophic ridges, where both vertical and horizontal bone augmentation is required.
