fabrication or implant placement in a prosthetically ideal position.1 Alveolar ridge defects that result from trauma, tooth extraction, or periodontal diseases often require periodontal-surgical correction before prosthetic treatment. Especially, in the esthetically important anterior arch segments, any surgical endeavor will require implants (osseous buildup) or fixed bridge constructions (sof...

We present the use of deproteinized bovine bone mineral and a non-crosslinked collagen membrane for reconstruction significant alveolar defect in this clinical case report,. The patient had extensive loss anterior maxillary region, posing challenge implant placement. Therefore, ridge preservation was performed following tooth extraction, resulting horizontal regeneration. Two implants were subs...

The objective of this study was to: (1) model the course of the lingual nerve (LN) in the third molar region using digitized data and (2) investigate landmarks to aid in predicting the position of LN. A MicroScribe 3-DX digitizer and Autodesk® Maya® 8.5 were used to create 3-D in-situ models of LN for seven human cadaveric specimens. Regression analysis demonstrated that an anteriorly positione...

Dentures are designed to replace missing teeth, and are worn by the patient for considerable period of time. The dentists skill lies in applying the principles of retention, stability and support efficiently in critical situations. Severely atrophic ridges provide decreased retention, support, and stability and pose a clinical challenge to the success of complete denture prostheses. The severel...

Alveolar bone splitting and immediate implant placement have been proposed for patients with severe atrophy of the maxilla in the horizontal dimension. A new modification of the classical alveolar bone splitting for the treatment of the narrow ridge in the maxilla is provided. Thirty-three dental implants in eight consecutive patients were evaluated retrospectively following the described modif...

PURPOSE Ridge expansion is used to widen narrow ridges with adequate height for implant placement. This human case series presents the clinical and histologic results of delayed expansion of mandibles by ultrasonic surgery. MATERIALS AND METHODS Patients with residual alveolar ridge width between 2.3 and 4.1 mm in the coronal area of the posterior mandible were included in the study. First, f...

This case report presents the correction of severe alveolar ridge atrophy due to congenital and iatrogenic factors. Implants that compromised the natural adjacent teeth and overall esthetics for this young patient were removed and replaced after significant vertical bone and soft tissue regenerative procedures. A treatment combination of bone graft particles, a nonresorbable membrane, and ename...

PURPOSE In case of large horizontal discrepancy of alveolar ridge due to severe resorption, cantilevered crown is usually an unavoidable treatment modality. The purpose of this study was to evaluate the clinical criteria for the placement of the aforementioned implant crown. MATERIALS AND METHODS The mandible model with 2 mm thick cortical bone and cancellous bone was fabricated from CT cross...

Alveolar ridge resorption is a natural consequence of teeth extraction, with unpleasant aesthetic and functional consequences that might compromise future oral rehabilitation. To minimize the biological alveolar resorption, several surgical procedures have been designed, so-called preservation (ARP) techniques. One important characteristic concomitant use biomaterial in ARP. In past decade, aut...
