Limited maxillary defects are commonly grafted with bone blocks harvested from the symphysis or the ramus; harvesting a second surgical site in the mandible increases both operative time and patient's postoperative morbidity. To overcome these disadvantages, the zygomatic buttress (ZB) was suggested as an alternative maxillary source of autogenous...

Bone augmentation techniques have increasingly been indicated for re-creating adequate bone height and volume suitable for dental implant sites. This is particularly applicable in the severely atrophic posterior maxilla where sinus perforation (ruptured Schneiderian membrane) is a very common complication and sinus floor elevation or lift is freque...

Odontogenic cysts are usually treated by enucleation (cystectomy). Limited cysts (less than 5 cm) are usually managed by primary excision (total cystectomy), whereas larger ones (exceeding 5 cm) are often decompressed or marsupialized. Because it consists only of opening a much smaller surgical window, decompression is regarded as a more conservati...

Aim: This study aims to estimate skeletal age of craniofacial shape obtained from cone beam computed tomography (CBCT)-defined facial and basicranial landmarks using geometric morphometrics method in a random sample of growing patients, and explore the correlation between craniofacial shape and skeletal age as determined from hand and wrist radiog...

This book is a special publication on an unusual and rare topic that is not often addressed in medical and dental literature; it provides medical and dental professionals, as well as undergraduate and post-graduate students and all healthcare professionals, with a comprehensive review of unusual and rare infections and inflammations of the cranium,...

Acquired Immune Deficiency Syndrome (AIDS) has been a great challenge for dental and medical health care professionals. Dentists are in daily contact with HIV positive patients.In most populations, HIV-infected patients suffer from racism and discrimination and often avoid reporting their medical history. But in many cases, patients are unaware of...

This book is not another typical publication on oral manifestations of systemic disease. On the contrary, material discussed here tackles the issue from a different, unprecedented view; we will be trying to suggest a clinical guide leading to a modest algorithm that enables the dental professional, within the scope of dentistry and oral medicine, t...

Objectives The aim of our study is to prove and validate the existence of an osteogenic progenitor cell population within the human maxillary Schneiderian sinus membrane (hMSSM) and to demonstrate their potential for bone formation. Materials and methodsTen hMSSM samples of approximately 2 × 2 cm were obtained during a surgical nasal approach for t...
