background: the accuracy and reproducibility of measurements in a locally made three dimensional (3d) simulator was assessed and compared with manual caliper measurements. materials and methods: a total of 20 casts were scanned by our laser scanner. software capabilities included dimensional measurements, transformation and rotation of the cast as a whole, separation and rotation of each tooth ...

The maxillary canine is second only to the mandibular third molar in its frequency of impaction. The prevalence is about 1.5% and the canine becomes ectopic more often palatally than buccally with over double the frequency. Management of this condition often faces general dental practitioners and orthodontic specialists. Mismanagement and failures in diagnosis may be costly in terms of clinical...

An 11-month-old female Labrador Retriever presented with a 3-month history of progressively enlarging, unilateral, ventral mandibular swelling. Cytology was consistent saliva, and the dog referred for further investigations. Computed tomographic (CT) imaging performed, findings were suggestive left-sided sialocoele. The underwent sialoadenectomy surgery left mandibular–sublingual gland complex....

A study was undertaken, using Panorex radiographs, to examine the effect on alveolar bone o f the time interval between the extraction o f a tooth and the commencement o f active tooth movement into the extraction site. There were 3 experimental groups o f 25 subjects each, namely, no treatment; active canine retraction begun within 3 weeks o f extraction o f the first premolar; and active cani...

Eruption disorders are numerous varying from delayed to complete failure of eruption. Primary failure of eruption (PFE) is a rare condition that involves arrested eruption of teeth with the absence of local or general contributory factors. Another rare and clinically challenging phenomenon is canine transmigration which is the intra-osseous movement of impacted canines across the midline. This ...

Introduction: Nowadays, using implants as a choice in patient's treatment plans has become popular. The aim of this study was to determine the prevalence of mandibular lingual and maxillary buccal concavity, mean concavity depth and angle and its relation to age and gender. Materials and Methods: In 200 CBCT, concavity depth and angle were measured in 2 mm superior to the inferior alveolar c...

Natural canine crowns are preferred as abutments for removable partial dentures because of their root morphology and bony support. However, preparing the rest seat on the lingual surface of a mandibular canine risks perforating the enamel. An alternative rest-seat preparation, on the marginal ridge of the canine crown, conserves tooth structure and provides a rest seat of adequate length and de...

A pier abutment is the lone standing tooth between two critically situated edentulous spaces, in a frequently seen clinical situation, missing first premolar and molar seen, which leads to design where canine second acts as terminal abutments abutment. This fulcrum may lead debonding of less retentive during function, overcome this situation non rigid connector advised. paper presents case repo...
