The purpose of this study was to develop an improved technique of alveolar ridge augmentation by distraction osteogenesis using distraction screws, and to investigate tissue reactions to titanium implants at the distraction site. The left mandibular premolars were extracted from 6 adult dogs. After 12 weeks, a box-shaped osteotomy of the alveolar bone was carried out, and distraction devices we...

A case is reported of a 66-year-old woman who could not use a conventional, full upper denture because of a gag reflex. In the maxillary alveolar ridge, restoration was performed on a moderately atrophied, edentulous anterior area and a small defect in the right-side posterior area. In the mandibular alveolar ridge, restoration was performed on a moderate osseous defect in each molar area resul...

W HEN people lose teeth, the problem of constructing a prosthesis without the aid of natural teeth, and which rests only on the alveolar ridge, must be met. In the maxilla where the surface of the hard palate covered with immovable mucous membrane is utilized for the adhesion and retention of the prosthesis, the problem is lessened because of the increased flat surface area. In the mandible con...

BACKGROUND Jaw bone and iliac bone are the most frequently used autologous bone sources for dental implant placement in patients with atrophic alveolar ridges. However, the comparative long-term stability of these two autologous bone grafts have not yet been investigated. The aim of this study was to compare the stability of simultaneously placed dental implants with autologous bone grafts harv...

Purpose: To systematically review clinical studies examining the survival and success rates of implants in horizontal ridge augmentation, either prior to or in conjunction with implant placement in the anterior maxilla. Materials and methods: A literature search was undertaken up to September 2012 including clinical studies in English with ≥ 10 consecutively treated patients and a mean follow-u...

OBJECTIVES The morphology of the alveolar process determines the retention and stability of prosthetic restorations, thereby determining the result of the therapy. Considering that the edentulous jaws may be affected by the atrophy process, it was hypothesized that the morphology of the alveolar process of the maxilla may be dependent on the anterior facial height and anatomy of the mandible. ...

background: lateral ridge split technique is a way to solve the problem of the width in narrow ridges with adequate height. simultaneous insertion of dental implants will considerably reduce the edentulism time. materials and methods: twenty-five patients who were managed with ridge splitting technique were enrolled. thirty-eight locations in both jaws with near equal distribution in quadrants ...

A case report of bilateral lymphangiomas of the mandibular alveolar ridge in the neonate is presented. This case is of interest in that it constitutes the first report of multiple lymphangiomas occurring within a single dental quadrant. Lymphangiomas generally are regarded as hamartomas and as such represent a developmental malformation of lymphatic vessels. The most common intraoral site of ly...

It is well established that tooth extraction is followed by a reduction of the buccolingual as well as the apicocoronal dimension of the alveolar ridge. Different measures have been taken to avoid this bone modelling process, such as immediate implant placement and bone grafting, but in most cases with disappointing results. One fundamental principle of bone physiology is the adaptation of bone...
