PURPOSE Different graft materials have been proposed to minimize the collapse of alveolar bone after tooth extraction. The aim of this study was to examine the use of porcine bone graft in fresh sockets via histomorphometric and in vivo gene expression profiling. MATERIALS AND METHODS Thirty fresh extraction sockets with three bone walls in 15 patients were selected. A split-mouth design was ...

BACKGROUND Alveolar ridge preservation could be performed immediately following tooth extraction to limit dimensional changes of alveolar process due to bone resorption. The aim of this study was to compare the clinical and histologic outcomes of socket preservation using two different graft materials; deproteinized bovine bone mineral (DBBM) and demineralized freeze-dried bone allograft (DFDBA...

PURPOSE Intraoral bone grafts are a convenient and acceptable source of autogenous bone for alveolar reconstruction due to bone origin similarity and less morbidity. In large bone defects, 1 tier might be insufficient to achieve the desired bone shape. The purpose of this article was to describe a multitier technique for reconstruction of extensive bone deficiency, using only intraoral block bo...

Treatment of severe compromised tooth in the maxillary anterior area still poses great challenge to the clinicians. Several treatment modalities have been proposed to restore the function and aesthetics in teeth with advanced periodontal disease. The present study aims to report a case of traumatic injury of a left-maxillary central incisor with ridge preservation, orthodontic movement, and imp...

BACKGROUND Insufficient alveolar bone height often prevents the placement of standard dental implants in the posterior part of edentulous maxilla. In order to increase adequately the vertical dimension of the reabsorbed alveolar process, a sinus lift procedure is often necessary. The aim of this study was to evaluate histologic results of a prehydrated corticocancellous porcine bone used in max...

Alveolar atrophy following tooth extraction remains a challenge for future dental implant placement. Immediate implant placement and postextraction alveolar preservation are 2 methods that are used to prevent significant postextraction bone loss. In this article, we report the management of a maxillary tooth extraction socket using an alveolar preservation technique involving placement of a con...

Distraction osteogenesis for correction of horizontal alveolar width deficiency was performed for 9 patients by using an alveolar crest widening device. Four prototypes were used during the course of the study until a final protocol was achieved. Under local anesthesia, a blind crestal osteotomy was carried out with minimal periosteal reflection. The horizontal distraction device was placed per...

Amidst several controversies involving orthodontic treatment and gingival recession, periodontal complications of tongue thrust habit especially in adults have not yet been fully investigated. This case report presents a successful clinical case of progressive spacing of incisors (PSI) with gingival recession treated with proper alveolar root housing and autogenous grafting. A 24 year old girl ...

Sinus lifting and reconstruction of localized alveolar defects are often required after closure of a large oroantral fistula (OAF) to allow for subsequent implant installation. This study describes a combined surgical technique that involves sinus lifting, bony closure, and reconstruction of the alveolar defect at the site of an OAF. The sinus membrane was reconstructed as a continuous layer by...

In the maxillary anterior region, reconstruction of the localized alveolar ridge defect is very important in enhancing the esthetics of fixed partial denture. A 40-year-old female patient presented with a chief complaint of the inconvenience and unesthetic problem of 3-unit maxillary anterior prosthesis due to alveolar ridge resorption. After removal of old prosthesis, intraoral examination rev...
