PURPOSE The purpose of this study was to evaluate the clinical feasibility of using a native collagen physical resorbable barrier made of bovine pericardium to augment localized alveolar ridge defects for the subsequent placement of dental implants. MATERIALS & METHODS There were 8 systemically healthy patients with 19 implant sites (aged 35 to 68 years), with inadequate dental alveolar ridge...

Horizontal bone augmentation of the maxillary and mandibular alveolar ridges has been conventionally performed using mini titanium alloy screws. The titanium alloy screws are used to fixate corticocancellous block grafts to the recipient site or for tenting the mucoperiosteum to retain particulate bone grafts. Nonresorbable guided tissue regenerative membranes reinforced with titanium have also...

Bone spreading technique (BST) is horizontal augmentation with minimal trauma for simultaneous implant placement and is an alternative Summer’s osteotome both clinical use as well as the armamentarium. The foremost advantage of the crest dilation technique is a substantially less invasive method; the buccal wall expands after the medular bone is compressed against the cortical bone. The lateral...

BACKGROUND The present study evaluated the outcome of ridge augmentation with cancellous freeze-dried block bone allografts in the posterior atrophic mandible followed by placement of dental implants. MATERIALS AND METHODS A bony deficiency of at least 3 mm, horizontally, vertically, or both, according to computerized tomography (CT) para-axial reconstruction served as inclusion criteria. Imp...

Ectodermal dysplasias are a heterogeneous group of inherited disorders characterized by defective formation of tissues derived from the embryonic ectoderm. Besides tissues of epidermal origin, other maxillofacial structures including hard and soft tissues can be affected. Disturbances in the early development of teeth frequently result in congenital absence or deformities of teeth. The lack of ...

the aim of this study was to compare the lateral window and osteotome techniques for sinus lifting using histological and histomorphometric methods.in this clinical trial 10 patients (a total number of 14 sinus areas) who needed implant treatment in the atrophic posterior maxilla were enrolled. in all the cases the residual bone height between the sinus floor and the alveolar crest was less tha...

introduction in spite of multiple applications of bioactive glasses, these materials have not been evaluated yet for ridge augmentation. due to the large number of patients who need ridge augmentation and the benefits of nova bone, in comparison with other alloplasts, this study was fulfilled for evaluation of nova bone ability in ridge augmentation. methods the samples of this experimental stu...
