Anthropometric measurements were performed on the teeth, dental arch and mandible. Parameters for these three categories were compared by means of canonical analysis in order to understand the morphological relationships existing among them. The sagittally projected length of the mandible had a significant role in the correlation between the size of the teeth and the length of the dental arch, ...

Progressive alveolar bone resorption after tooth extraction may lead to surgical and prosthetic-driven difficulties, especially when deciding to use a dental implant to replace the extracted tooth. This case report discusses an irreparable lower left second premolar tooth with a periodontal lesion on the buccal side. A preservative tooth extraction was performed. Then, the socket was grafted wi...

OBJECTIVE To assess if overbuilding the buccal plate or using a dual-layer socket grafting technique prevents alveolar bone resorption and enhances final ridge width, height, and volume after tooth loss in an animal model. MATERIAL AND METHODS In eight beagle dogs bilateral second (P2)-, third (P3)-, and fourth (P4) premolars were endodontically treated. All bilateral mandibular first premola...

BACKGROUND The initial thickness of maxillary bone has significant impact on the responding level of facial bone and soft tissue after extraction and immediate implant placement. A prevailing notion is that following implant placement in fresh extraction sites, at least 2 mm of facial bone is needed to prevent soft tissue recession, fenestration, and dehiscence. PURPOSE The purpose of this st...

abstract alvelolar hydatid disease is caused by e. multilocularis. human infection occurs at the larval stage of this small tape worm (1.2 to 4.5 mm). in this article we studied alveolar hydatid disease in a 50 year old woman who presented with a hepatic mass. liver biopsy and histopathologic evaluation showed alvelolar hydatidosis of the liver. then resection of the left lobe of liver was done...

pulmonary alveolar proteinosis, (pap) is a rare disease of unknown etiology, characterized by accumulation of intra-alveolar proteinaceous material which is rich in lipid and positive on periodic acid-schiff stain. two clinically different pediatric types have been defined as congenital pap which is fulminant and fatal, and a late-onset pap which is similar to the adult form and less severe. ei...

background & aim: dental implants should be surrounded with at least 1mm bone. assessing ridge width is an important part to achieve this goal. the use of ridge mapping to assess bone levels available avoids some of the problems associated with ct-scanning. the aim of this study was to assess the accuracy of ridge-mapping compared to ct-scan in determination of bony ridge widths. methods & mate...

BACKGROUND The aim of this study was to assess the influence of ridge morphology on the amount of horizontal bone augmentation achieved with the sandwich bone augmentation (SBA) technique in the reconstruction of buccal dehiscence defects on dental implants. METHODS Cone beam computed tomography (CBCT) was used to assess bone width changes in 26 patients who participated in a randomized contr...

BACKGROUND Reliable implant-supported rehabilitation of an alveolar ridge needs sufficient volume of bone. In order to achieve a prosthetic-driven positioning, bone graft techniques may be required. PURPOSE This prospective cohort study aims to clinically evaluate the amount of resorption of corticocancellous fresh-frozen allografts bone blocks used in the reconstruction of the severe atrophi...

OBJECTIVES To evaluate the effectiveness of beta tricalcium phosphate (β-TCP) alone compared to β-TCP and Demineralized Bone Matrix (DBM) in regenerating localized horizontal maxillary alveolar ridge deficiencies prior to implant placement. STUDY DESIGN The study included 20 patients with horizontal maxillary ridge deficiencies limited to one or more neighbouring teeth and initial ridge width...
