The extent of anomalies and developmental aberrations in hemifacial microsomia (HFM) have not yet been fully delineated. Thus, the developmental pattern of the dentition in patients with HFM remains unclear. This study was conducted to investigate the development of the dentition in subjects with varying degrees of HFM and to compare the affected side with the unnaffected side and with data fro...

We propose a fully automatic method for tooth detection and classification in CT or cone-beam CT image data. First we compute an accurate segmentation of the maxilla bone. Based on this segmentation, our method computes a complete and optimal separation of the row of teeth into 16 subregions and classifies the resulting regions as existing or missing teeth. This serves as a prerequisite for fur...

Replacement of missing anterior tooth is the most esthetic challenging situation. Following tooth loss, reduction in bone height is often accompanied by alteration in gingival architecture. Immediate implant placement in freshly extracted socket is said to decrease these. This case report describes the step by step procedure for the same. Implant placement was followed by early implant loading ...

This clinical report describes a treatment for the replacement of a missing mandibular anterior tooth using a cantilever single-retainer resin-bonded fixed partial denture (RBFPD), fabricated from zirconium dioxide (ZrO2) ceramic. No clinical complications were observed at the 2-year 6-month follow-up examination after placement of the ZrO2 ceramic RBFPD, and satisfactory functional and estheti...

A 40-year-old female presented with a 10 year history of left sided facial pain and occasional purulent nasal discharge, refractory to antibiotics. Dental examination showed 3 missing teeth in left maxilla one of which had no history of extraction. X-ray paranasal sinus showed a bony opacity in the maxillary sinus but nasal endoscopy was normal. C.T. scan revealed a radio-opaque shadow arising ...

We may think of implants as being an invention of modern times. But history shows evidences of ancient civilization trying to replace missing teeth by banding artificial tooth replacements to remaining teeth or by using gold ligature wires to stabilize periodontally weak teeth. The first clear evidence of tooth replacement is from the early Egyptians in 2500 BC where attempts were made to stabi...

There has been disagreement for more than 100 years concerning the presence or absence of deciduous and successional third premolars in dentition Australian dasyurid marsupial Dasyurus viverrinus as well other species genus Dasyurus. Most authors during 19th 20th centuries have considered missing premolar to be family both jaws, part because reduction size many genera dasyurids. While authors, ...

The anterior maxilla is the most prone region to the trauma during childhood, and tooth loss sometimes happens due to trauma. Replacing the missing teeth has always been one of the dentists' challenges in children and adolescents, since their dentofacial growth is not complete. Autotransplantation of mandibular premolars with two-thirds or three-quarters of root formation provides the best prog...

A common dilemma in adult orthodontic treatment is deciding how best to treat missing posterior teeth. One treatment option is to orthodontically close the space. But closure can be difficult, especially if the open space is in the maxillary posterior area, because tooth movement through the maxillary sinus is limited. The increased difficulty of moving teeth in the maxillary sinus is similar t...

Ankylosis of primary mandibular molars has been routinely found to be associated with various developmental disturbances in permanent dentition such as aplasia of the succedaneous tooth, ectopic eruption of the premolar, infraoclusion of the ankylosed tooth leading to tipping of the first permanent molar etc. This article describes a rare case where there was ankylosis of a mandibular second pr...
