Guided bone regeneration (GBR) is a reconstructive procedure of alveolar ridge using membranes. This procedure is indicated when there is no sufficient bone for implantation, or in the case of optimal implant installation for esthetic or functional needs. GBR can be performed before implant placement, when there is not enough bone for initial stability of implants and less predictable outcomes ...

STATEMENT OF PROBLEM No study provides human histologic evidence regarding the use of resorbable collagen membrane for a 2-stage localized alveolar augmentation procedure. PURPOSE The purpose of this pilot study was to evaluate the potential of use of a resorbable collagen membrane in conjunction with an autogenous bone graft and inorganic bovine mineral (IBM) for labial/buccal alveolar ridge...

The alveolar ridge shape plays an important role in predicting the demand on the support tooth and alveolar bone in the removable partial denture (RPD) treatment. However, these data are unclear when the RPD is associated with implants. This study evaluated the influence of the alveolar ridge shape on the stress distribution of a free-end saddle RPD partially supported by implant using 2-dimens...

Congenital epulis, or granular cell tumour, is a rare, benign intraoral tumour present on the mucosa of the alveolar ridge, with the potential to interfere with respiration and feeding. Treatment involves surgical excision, and recurrences are rare. The management of the alveolar deficiency associated with this tumour has not previously been addressed. In the present report, a patient with a ty...

PURPOSE This retrospective study investigated whether or not implants can be placed successfully without sinus grafts in atrophic posterior maxillary ridges with < or = 4 mm of bone utilizing the localized management of the sinus floor technique as described by Bruschi and coworkers. MATERIALS AND METHODS Fifty-eight implants were placed in 34 consecutive patients with an average vertical hei...

This report documents the clinical, radiographic, and histologic outcome of a custom-made computer-aided-design/computer-aided-manufactured (CAD/CAM) scaffold used for the alveolar ridge augmentation of a severely atrophic anterior mandible. Computed tomographic (CT) images of an atrophic anterior mandible were acquired and modified into a 3-dimensional (3D) reconstruction model; this was trans...

objective: alveolar ridge preservation in patients with inadequate bone volume is one treatment option for successful implant placement and can be done by using bone graft materials. on the other hand, ceno bone has been recently produced by hamanand saz baft kish co. as a bone bioimplant of allograft origin. this study aimed to assess the clinical, histologic and histomorphometric results of b...

This report describes treatment of a patient using vertical alveolar ridge augmentation performed prior to transposition of the inferior alveolar nerve (IAN). A preoperative computerized tomographic (CT) scan revealed 2 to 3 mm of bone above the canal in the left mandibular molar region. An autogenous bone graft harvested from the chin area was utilized along with a titanium mesh for vertical a...

The goal of all prosthetic treatment is to obtain a satisfying functional and esthetical oral status. In a fixed bridge, the pontic frequently give the impression that they rest on the top of the ridge rather than emerge from within the alveolar process & lack marginal gingiva & interdental papillae. Black triangles, which almost always interfere with dentofacial esthetics, are present in the e...

Since prognostic indicators are likely to take on increasing importance as a diagnostic tool for selection of patients for implant provision, this study investigated the influence of the shape and resiliency of the mandibular alveolar ridge on the retention and stability of conventional complete dentures. Ninety- three edentulous patients wearing both maxillary and mandibular conventional compl...
