PURPOSE The purpose of this report is to present a reliable surgical and prosthodontic protocol for the treatment of the atrophic maxilla by placing four zygomatic implants. MATERIALS AND METHODS The surgical and prosthodontic procedures are described for the retreatment of a 63-year-old woman who had previously undergone an iliac crest bone graft transplant, which had resorbed. RESULTS It ...

BACKGROUND All clinicians are aware of the difficulty of installing a dental implant in posterior maxilla because of proximate position of maxillary sinus, insufficient bone width, and lower bone density. This study is to examine which factors will make the implantation in the posterior maxilla more difficult, and which factors will affect the postoperative implant stability in this region. M...

BACKGROUND Periapical cysts (PC) and periapical granulomas (PG) are the two most common chronic inflammatory periapical diseases, but their clinicoradiological characteristics can vary depending on the methods employed in each study. The aim of the present work was to analyze the clinical and radiological profile of a series of PC and PG diagnosed in a Brazilian population. MATERIAL AND METHO...

A fragmentary diapsid left maxilla from the Bathonian Peski locality in Moscow Region, previously referred to Choristodera, is identified as Lepidosauromorpha indet. This specimen represents fi...

Computed tomography (CT) scanning is very useful in identifying and evaluating the location, size, and suspected pathological diagnosis of lesions such as cysts, tumors, and infections. At the same time, it aids in the elucidation of bone and surrounding soft tissue invasion of lesions with high resolution.1, 2 In the maxilla and mandible, teeth are included and the CT capacity there can distin...

The maxilla located in the mid face between strong frontal bars and the andibula. The maxilla consists of a body and four processes: Frontal, zygomatic, palatine, and alveolar processes. The body involves a space to form the maxillary sinus. Different, patterns of maxillary fractures were defined by René Le Fort, which he designed ‘‘lines of weakness’’ and he also described sagittal fractures o...

Osteomyelitis was relatively common before the era of antibiotic therapy. Today osteomyelitis of facial bones is a rare condition. Maxillary osteomyelitis is rare compared to mandible osteomyelitis because extensive blood supply & strut like bone of the maxilla make it less prone to chronic infection. We report a rare case of Osteomyelitis involving whole of the Maxilla in a 50 year old male pa...

Anesthesia of the soft and hard tissues of the maxilla may require up to 5 injections. Thus, the aim of this study was to evaluate the anesthetic efficacy of the anterior middle superior alveolar (AMSA) and supraperiosteal injection techniques during subgingival scaling and root planing (SRP). Thirty individuals with periodontitis were scheduled for SRP on the buccal aspect of teeth in the ante...

OBJECTIVE To elucidate relationships between the dental roots and surrounding tissues in order to prevent complications after placement of a miniscrew. MATERIALS AND METHODS Twenty human mandibles and maxillas were used for this study. In the 200 sections of each mandible and maxilla, nine items were measured to investigate the relationships between the dental roots. RESULTS The interroot d...

OBJECTIVES The aim of this study is to evaluate the position of impacted third molars based on the classifications of Pell & Gregory and Winter in a sample of Iranian patients. STUDY DESIGN In this retrospective study, up to 1020 orthopantomograms (OPG) of the patients who were referred to the radiology clinics from October 2007 to January 2011 were evaluated. Data including the age, gender, ...
