OBJECTIVES Orthodontic mini implants can be inserted at the interradicular site. The bone quality at this site may affect the stability and anchorage of the implant. Bone density is clinically evaluated by Hounsfield units (HU) obtained from cone beam CT (CBCT). The objective of this study was to determine the correlations between HU, microhardness and cortical bone thickness of interradicular ...

Mathematical modelling of human mandible and its temporomandibular joints (TMJs) is one of the most important steps for developing a powerful forecasting tool to analyse the stress/strain behaviour of a human masticatory system under occlusal loads. In this work the structural behaviour of a mandible with articular discs, undergoing a unilateral occlusion, is numerically analysed by means of bo...

The mandible is the strongest bone of the skull, and it is commonly utilized in forensic anthropology for determination of sex from skeletal remains. It has been extensively studied by both metric and non-metric methods, but for this purpose an intact mandible is often required. This study was conducted in Indian population using discriminant function analysis to calculate the accuracy of two p...

OBJECTIVE To define parameters that enable the objective diagnosis of anomalies of the position and/or size of the fetal mandible in utero. DESIGN Fetuses at 18-28 gestational weeks were examined by two- and three-dimensional ultrasound. The study included normal fetuses and fetuses with syndromes associated with known mandible pathology: Pierre Robin sequence or complex (n = 8); hemifacial m...

Odontomas are the most common tumor-like (hamartoma) odontogenic lesions in gnathic bones. There two main types: complex odontoma which is composed mainly of amorphous calcification, and compound characterized by irregular tooth-like structures. generally asymptomatic cases involve only one quadrant maxilla or mandible. The treatment choice surgical removal. aim present study to report a rare c...

OBJECTIVES This study aimed at clarifying the morphological interactions among the cranial base, face, and mandible, to improve the assessment and treatment of skeletal malocclusions involving the mandible. DESIGN Untreated adult subjects (n=187) were grouped according to standard cephalometric criteria of vertical and sagittal relationships. Geometric morphometrics were used to test the null...

BACKGROUND Among bones building the axial and appendicular skeleton, the mandible is characterized by unique morphological and functional traits. The aim of the study was to evaluate morphological, densitometric and mechanical properties of mandible in 5-month-old Polish Merino sheep. Using quantitative computed tomography, volumetric bone mineral density (vBMD) and calcium hydroxyapatite densi...

Bone formation in small deposits following the loss of part of the mandible has often been reported in the literature, but reports of complete bone regeneration extending over the entire anterior mandible from angle to angle is rare. Even rarer, are reports on the behaviour of such new bone in terms of facial development, over a long term and the effect of load carrying on it. Presented here is...

BACKGROUND Esthetics and the health of oral implants are based upon the soft tissue reaction and biologic width (BW). METHODS Twelve dental implants were placed in the maxilla and mandible of a patient who smoked. Permanent standard abutments and temporary restorations were immediately fixed in place during the surgery stage. The definitive restorations were placed 4 months after loading with...
