OBJECTIVE To compare the anchorage effects of the implants and the headgear for patients with anterior teeth retraction in terms of incisor retraction, anchorage loss, inclination of maxillary incisors, positional change of maxillary basal bone, and treatment duration. MATERIALS AND METHODS An electronic search for relative randomized controlled trials (RCTs) prospective and retrospective con...

BACKGROUND Facial deformation as a sequela of leprosy is caused not only by a saddle nose but also by regression of the maxilla, as well documented in paleopathological observations of excavated skeletal remains of patients with leprosy. However, maxillary changes in living patients have been evaluated only by the subjective visual grading. Here, we attempted to evaluate maxillary bone deformat...

The brown tumor or osteitis fibrosacystica is a benign bone lesion that caused by hyperparathyroidism. This complication has been decreased by diagnosis and successful treatment of hyperparathyroidism. The brown tumor of hyperparathyroidism results from a metabolic disorder that affects long bones, ribs, and pelvis. The maxillary involvement is rare. Parathyroidectomyis a good choice for patien...

BACKGROUND The amount of postoperative maxillary relapse of two different bone graft materials after Le Fort I osteotomy were compared in this study. OBJECTIVES The aim of this study is to compare postoperative maxillary relapse rates using heterologous and autologous graft materials after Le Fort I osteotomy. MATERIAL AND METHODS A total of 80 patients who had developmental malocclusion we...

PURPOSE The purpose of the study was to evaluate the magnitude of ridge augmentation with titanium mesh, overall graft success, anatomic location of ridge defects and their relationship to mesh exposure. MATERIALS AND METHODS This retrospective study evaluated 44 patients who received mandibular or maxillary reconstruction with autogenous particulate bone graft and titanium mesh for the purpo...

statement of the problem: various researchers have suggested the use of β2-adrenergic receptor antagonists in prevention or treatment of bone resorption. purpose: this study aimed to evaluate the effect of β2-adrenergic receptor antagonists on number of osteoclasts and osteoblasts involved in the healing of extraction socket of maxillary first molar in rats. materials and method: maxillary firs...

OBJECTIVE To compare a four- and six-implant maxillary overdenture after an observation period of 5 years. MATERIAL AND METHODS Fifty subjects with functional problems concerning their maxillary denture, who had ample bone volume in the anterior region to place four or six implants, were included and randomly assigned to either group. Implant and overdenture survival, clinical performance, ma...

BACKGROUND Loss of the interproximal dental papilla may cause functional and, especially in the maxillary anterior region, phonetic and severe esthetic problems. The purpose of this study was to investigate whether the distance from the contact point to the bone crest on standardized periapical radiographs of the maxillary anterior teeth could be correlated with the presence of the interproxima...

Objective: The aim of this preliminary study was to assess changes in tooth length and alveolar thickness following retraction of maxillary incisors. Methods: A total of 11 patients presenting severe maxillary dentoalveolar protrusion revealed by initial (T1) cone-beam computed tomography (CBCT), and whose treatment plan included extraction of maxillary first premolars and retraction of maxil...
