AIM To assess the degree of jawbone asymmetry by drawing vertical lines on digital panoramic radiographs of paediatric patients with right or left unilateral cross-bite. MATERIALS AND METHODS STUDY DESIGN The sample consisted of 217 paediatric patients of both genders, aged 6-9 years. A set of vertical lines was drawn on the side of the mandible with the cross-bite and on the side without ...

Maxillofacial images must be examined to find pathologies not identified during clinical examination. Unicystic ameloblastoma (UA) extending to the mandibular body and ramus was neglected on initial panoramic radiographic examination. After orthodontic therapy, a huge lesion was observed clinically and through imaging exams. After the conservative surgery, no recurrence was observed during five...

The purpose of this study was to measure the changes in facial, occlusal, and skeletal relationships in patients with active unilateral condylar hyperplasia whose sole treatment was a low condylectomy. A retrospective observational descriptive study was conducted. All patients had undergone a low condylectomy as the sole or initial surgical treatment. The size of the condylar segment removed wa...

BACKGROUND The mandibular foramen is of particular importance to the dentist and dental specialist as it marks the beginning of the mandibular canal, which transmits inferior alveolar nerve and vessels. The aim of this study was the localization of anteroposterior and superioinferior position of the mandibular foramen on the panoramic radiographs in adolescent and young adult in a selected samp...

A new species of intertidal acorn barnacle Tetraclita ehsanisp. n. was identified from the Iranian coast in the Gulf of Oman. Tetraclita ehsanisp. n. inhabits low exposed rocky shores and also attaches to shells of molluscs and the barnacle Megabalanus species. Parietes of Tetraclita ehsani ranged from white to pink which is different from Tetraclita serrata (in South African waters), which has...

Preoperative surgical simulation in orthognathic surgery has progressed in recent years; the movement of the mandible can be anticipated through three-dimensional (3D) simulation surgery before the actual procedure. In this case report, the mandible was moved to the intended postoperative occlusion through preoperative surgical 3D simulation. Right-side condylar movement change was very slight ...

A new species of the priscomilitarid amphipod, Priscomilitaris heike, from the Seto Inland Sea, Japan, is named and described. This new species is the third species of Priscomilitaridae and the second species of Priscomilitaris. Additionally, nucleotide sequences of nuclear 28S rRNA and histone H3 as well as mitochondrial cytochrome c oxidase subunit I from its holotype were determined. Priscom...

The mouse mandible has long served as a model system for complex morphological structures. Here we use new methodology based on geometric morphometrics to test the hypothesis that the mandible consists of two main modules, the alveolar region and the ascending ramus, and that this modularity is reflected in the effects of quantitative trait loci (QTL). The shape of each mandible was analyzed by...

Reproduction of anatomical structures by rapid prototyping has proven to be a valid adjunct for craniofacial surgery, providing alternative methods to produce prostheses and development of surgical guides. The aim of this study was to introduce a methodology to fabricate asymmetric human mandibles by rapid prototyping to be used in future studies for evaluating mandibular symmetries. Stereolith...

UNLABELLED Among the osteotomies performed in orthognathic surgery, the sagittal osteotomy of the mandibular ramus (SOMR) is the most common, allowing a great range of movements and stable internal fixation (SIF), therefore eliminating the need of maxillomandibular block in the postoperative period. OBJECTIVES The purpose of this study was to evaluate the biomechanical resistance of three nat...
