This study aims to determine restoration and revitalization efforts after the degradation of mangrove ecosystems in Paluh Merbau. The observation method is direct area. results show that ecosystem fragile sensitive change. Mangrove forest Merbau has been very severe; much vegetation fallen due being unable withstand abrasion sedimentation coastal waters continues experience area shrinkage. Rest...

In this paper, the authors present a convergence analysis for the NAS-RIF algorithm used in blind image restoration. A novel approach is presented to determine su cient conditions for the global convergence of the technique. The approach is general to many signal processing algorithms and incorporates Lyapunov's direct method used commonly in nonlinear system analysis. The su cient conditions f...

The ultimate goal for an esthetic rehabilitation is the restoration of health, beauty, and function to the patient. This article illustrates a predictable system to guide the clinician with tooth preparations for porcelain veneer restorations based upon the additive diagnostic wax-up. This system promotes a preparation technique using a series of guides that direct the clinician to reduce only ...

background: this study was designed to compare the clinical performance of composite, strip crowns, biological restoration, and composite with stainless steel band when used for the coronal build-up of anterior teeth. materials and methods: a total of 20 patients aged 3-6 years presenting with mutilated primary anterior teeth due to caries or trauma were selected for the study using randomized ...

Direct bonding is the most commonly-used treatment for the conservative esthetic restoration of anterior teeth. Class IV defects deserve special attention because of their high incidence in anterior teeth. One of the major challenges for the practitioner treating defects in this category is disguising the fracture line, through the correct use of masking and restorative resins, to make the rest...

Diseases such as gastroesophageal reflux disease (GERD), bulimia, anorexia, and extrinsic alimentary factors may cause dental erosion (DE). The minimally invasive therapeutic attitude preserves the remaining healthy tooth structure. In the earlier stages, the direct restoration of dental lesions is possible, using composite materials. In advanced stages of DE, prosthetic treatments are recommen...

Onlay is an extra-coronal restoration usually involving same area as inlay restoration and portion of outer cuspal slope, it is indicated in cases of steep cuspal inclines as wedging force tends to direct forces not parallel to the long axis of tooth [3]. The versatile inlay and onlay restorations require meticulous care in preparation, but when properly designed are extremely useful as durable...

We use the ‘‘magic TV’’ network with the maximum a posteriori (MAP) criterion to restore a space-dependent blurred image. This network provides a unique topological invariance mechanism that facilitates the identification of such space-dependent blur. Instead of using parametric modeling of the underlying blurred image, we use this mechanism to accomplish the restoration. The restoration is rea...

Whether a direct or indirect approach is taken when faced with a patient requiring restorative treatment, creating and designing natural occlusal surfaces is not only a challenge, but also important to achieve proper bite registration, occlusion, and masticatory function. The indirect restoration described in this article features a computer-aided design/computer-aided manufacture (CAD/CAM)-gen...
