Most common techniques for alveolar bone augmentation are guided bone regeneration (GBR) and autologous bone grafting. GBR studies demonstrated long-term reabsorption using heterologous bone graft. A general consensus has been achieved in implant surgery for a minimal amount of 2 mm of healthy bone around the implant. A current height loss of about 3-4 mm will result in proper deeper implant in...

PURPOSE After extraction, the alveolar bone tends to undergo atrophy in three-dimensions. The amount of alveolar bone loss in the horizontal dimension has been reported to be greater than the amount of bone loss in the vertical dimension, and is most pronounced in the buccal aspect. The aim of this study was to monitor the predictive alveolar bone level following the extraction of anterior teet...

Implant-based rehabilitation of edentulous mandibular posterior sectors tends to be complicated by the presence of bone atrophy. Following tooth loss, cortical bone suffers greater resorption on the vestibular than on the lingual aspect, and patients typically present narrow and low alveolar crests. In cases of moderate to severe mandibular atrophy, the bone height between the alveolar crest an...

A clinical case of bilateral cleft palate repair using previous tongue flap followed by Alveolar Bone Grafting(ABG). After pre-surgical orthodontics a surgical procedure whereby Flaps were reflected, nasalbeds prepared on both sides. cortico-cancellous bone 2 cm was harvested from iliac crest and grafted inclefts. Patient is kept follow up to monitor healing, postoperative results any post- ope...

PURPOSE The healing process following tooth extraction apparently results in a pronounced resorption of the alveolar ridge. As a result, the width of alveolar ridge is reduced and severe alveolar bone resorption occurs. The purpose of this experiment is to clinically and histologically evaluate the results of using horse-derived bone mineral for socket preservation. METHODS The study comprise...

With the tremendous progress made in establishing the relative role of the external or the environmental causes of disease, the individual or genetic differences are assuming increasing importance. Periodontal bone loss from periodontitis may be either horizontal, resulting in a regular alveolar crest at a level more apical to the normal, or vertical, leading to the formation of defects contain...

introduction radiographs provide unique information about the status of periodontium and permanent records of condition of bone throughout the course of the disease. interproximal images record the distance between the cementoenamel junction and the crest of the interradicular alveolar bone, more accurately. the aim of this study was to investigate the effect of different vertical angles of x-r...

This study reviews the outcome of implant placement in 61 patients after augmentation of severely atrophic alveolar bone with a bovine bone mineral, Bio-Oss. Bone augmentation was performed at 4 different sites: alveolar crest width, alveolar crest height, antral cavity, or nasal cavity. After a mean healing time of 11.9 months, 231 implants were placed in Bio-Oss bone. The time of loading of t...
