3-D Evaluation of temporary skeletal anchorage sites in the maxilla.

Waldenström macroglobulinemia is defined by the presence of monoclonal immunoglobulin IgM type (M-IgM) and evidence of lymphoplasmacytic bone marrow infiltration. The disease has an indolent course, the treatment is only initiated when the disease has begun to damage its carrier. The following symptoms are regarded as proven indications for initiating therapy: B symptoms, symptomatic lymphadenopathy, splenomegaly, anemia with hemoglobin below 100 g / l or thrombocytopenia < 100 × 10(9)/l, caused by lymphoplasmacytic bone marrow infiltration. Frequent indications for initiating treatment includ

Transverse Asymmetries of the Maxilla Even in Healthy and Apparently Symmetrical Subjects.

In the formulation of an orthodontic treatment plan, the three-dimensional analysis of the dental arches represents a fundamental moment for … phology, but this in turn determines the function. In the case of unilateral mastication, the upper maxilla will be asymmetrical, so growing patients will have compensation on other skull bones. From these considerations arises the need for a careful study of the horizontal plane of the maxilla in the presence of a malocclusion during diagnostic evaluatio …

Rare case report of an aggressive follicular lymphoid hyperplasia in maxilla.

Follicular lymphoid hyperplasia is a very rare though benign reactive process of an unknown pathogenesis that may resemble a follicular lymphoma, clinically and histologically. Oral reactive follicular hyperplasia (RFH) has been described on the hard or soft palate and at the base of the tongue. We describe here the first case of RFH presenting as an aggressive tumor on the right posterior side of the maxilla in a 24-year-old male patient. The lesion had a clinical evolution of 18 months and was noticed after the surgical extraction of the right third molar, although we cannot assume a cause-e…

A Case of Pentastomiasis at the Left Maxilla Bone in a Patient with Thyroid Cancer.

Pentastomiasis, a zoonotic parasite infection, is typically found in the respiratory tract and viscera of the host, including humans. Here, we report for the first time an extremely rare case of intraosseous pentastomiasis in the human maxilla suffering from medication related osteonecrosis of the jaw (MRONJ). A 55-year-old male had continuously visited the hospital for MRONJ which had primarily developed after bisphosphonate and anti-neoplastic administration for previous bone metastasis of medullary thyroid cancer.
