AIM Implant rehabilitation of the atrophic right posterior mandible in a 48-year-old woman using dehydrated homologous bone block, shaped with a computer aided design-computer aided manufacturing (CAD-CAM) system, to avoid harvesting of autologous bone block and to assure a perfect fitting of the block above the alveolar crest. RESULTS After 7 months, 6.09, 7.36, and 8.08 mm (mean, 7.18 mm) o...

© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim 1 wileyonlinelibrary.com To prevent ridge resorption and postextraction alveolar bone loss, immediate or early implant placement procedures have become a key component and standard-ofcare treatment following tooth removal in clinical dentistry.[4] Several clinical techniques and many biomaterials have been introduced in an effort to preserve alv...

This study aimed to develop a functionally graded membrane (FGM) to prevent infection and promote tissue regeneration. Poly(l-lactide-co-d,l-lactide) encapsulating platelet-derived growth factor (PDLLA-PDGF) or metronidazole (PDLLA-MTZ) was electrospun to form a nanofibrous layer on the inner or outer surface of a clinically available collagen membrane, respectively. The membrane was characteri...

For years, in order to improve bone regeneration and prevent the need of a second stage surgery to remove non-resorbable membranes, biological absorbable membranes have gradually been developed and applied in guided tissue regeneration (GTR). The present study's main objective was to achieve space maintenance and bone regeneration using a new freeze-dried developed porcine collagen membrane, an...

Post-extraction crestal bone resorption is common and unavoidable which can lead to significant ridge dimensional changes. To regenerate enough bone for successful implant placement, Guided Bone Regeneration (GBR) is often required. GBR is a surgical procedure that uses barrier membranes with or without particulate bone grafts or/and bone substitutes. There are two approaches of GBR in implant ...

Implants are typically placed after performing ridge expansion by inserting screws of gradually increasing thickness and good clinical outcomes are often obtained. We placed 11 implants in 6 patients, and one implant failed during osseointegration but it was replaced immediately after removal and successful prosthetic treatments were completed. During these surgeries, buccal cortical plate comp...

Reduction of the original height and width of the alveolar bone of an edentulous site precludes optimal positioning of implant fixtures and may esthetically compromise the prosthesis. Ridge expansion at the time of extraction can prevent the need for ridge reduction and reduces the number of surgical interventions.A patient with a narrow ridge with buccal deformity was treated for the staged pl...

introduction: tessier facial cleft is among the rarest facial clefts reported in literatures and there are many issues arguing about its multidisciplinary repairing techniques. tessier number 4 and 5 are extremely rare facial anomalies. there are few literatures describing these clefts and their surgical modalities. number 5 tessier cleft begins medial to oral commissure in the upper lip and ex...

Objectives: Edentulous is the most common organ defects in the communities& shows the prevalence of this disability community's health. the World Health organization (WHO) recorded index periodically at intervals of a certain age as a determinant of oral health status has been recommended. the aim of this study was to radiographic evaluation of alveolar ridge height of maxillary and mandibular ...
