This document summarizes a clinical study on using the zygomaticomaxillary buttress as a donor site for bone grafting to augment maxillary alveolar defects for dental implant placement. It describes the anatomy of the zygomaticomaxillary buttress and reviews its advantages as a donor site, including good bone quality and quantity while avoiding complications from other sites. It then presents a case study where bone was harvested from the buttress to graft a maxillary defect and allow successful implant placement, with follow-up showing osseointegration and no complications. The conclusion is that the zygomaticomaxillary buttress is a viable donor site for limited bone grafting for dental implants.

Dr. Ahmed M. Adawy, Professor Emeritus, Dep. Oral & Maxillofacial Surgery. Former Dean, Faculty of Dental Medicine, Al-Azhar University. Condylar fractures represent one of the most controversial issues in maxillofacial traumatology regarding classification, diagnoses and therapeutic management. Classification systems of condylar fracture is discussed. Diagnosis is usually based on history clinical examination and radiographic finding. Treatment ranges from observation, jaw exercises to closed or opened interventions. For years closed reduction was thought to be essentially complication-free. Several serious complications however have been reported including temporomandibular joint ankyloses, malocclusion, mandibular deviation and the generative joint pathology. The absolute and relative indications for open reduction is given. The debate between supporters of open or closed reduction is still continuing and the issue has not been resolved. However, the final choice treatment modality should takes into account the location of the fracture, age of the patient, presence or absence of other associated injuries, cosmetic impact of the surgery and presence of other systemic medical conditions.

TMJ ANKYLOSIS of the Jaw and its clinical significanciesVamshi392572
This document provides an overview of temporomandibular joint (TMJ) ankylosis, including its embryology, anatomy, causes, pathogenesis, classification systems, clinical features, investigations, and management. Some key points:
- TMJ ankylosis is a bony or fibrous adhesion of the joint components that limits mouth opening. It is commonly caused by trauma or infection.
- Following trauma, haemarthrosis leads to organization of the intra-capsular hematoma and bone formation, resulting in ankylosis.
- Classification systems describe the extent of ankylosis based on the area of bony fusion. Management involves aggressive resection, coronoidectomy, inter
Bearing Capacity of Shallow Foundation.faizanNoor8
This document discusses the bearing capacity of shallow foundations. It defines bearing capacity as the maximum average contact pressure between the foundation and soil without causing shear failure. Shallow foundations are those where the depth is less than the width, and are commonly used as they are economical and easy to construct. Terzaghi's bearing capacity theory states that the ultimate bearing capacity of a shallow foundation depends on the cohesion of the soil, overburden pressure, and unit weight of the soil. It provides equations to calculate the ultimate bearing capacity for square, continuous, and circular footings based on this theory.
