Fixed anterior bite raising appliance [FABRA]

Deep overbite problem may result either from upward and forward rotation of the mandible or over-eruption of lower incisors teeth. Correction of this problem can be achieved by various methods. A fixed anterior bite-raising appliance was introduced. However, this appliance can be modified to overcome other problems. Such an appliance can be of great value to the orthodontist since it is considered as a multi-disciplinary appliance

Measurements of facial points during growth utilizing centroids

The aim of the present study was to Investigate the movement of facial cephalometric points during growth In a vertical and horizontal direction. A sample of 36 lateral skull radiographs were selected from a bigger sample. Half of the radiographs were taken at aged 9 years +/- 2 months and the other 18 radiographs were taken at 16 years +/- 2 months. The sample was traced and digitized. The computer was able to produce a line joining the centres of the skull, cranium and face CFC [Cranio Facial Centroid line]. Fifteen [15] cephalometric points were located for each subject and measured to a horizontal and a vertical line, based on the centre of the cranium and oriented 450 to the CFC. Millimetric measurements were used to calculate ratios. The data were subjected to descriptive statistics and student t-test. The greatest percentage change for the pooled sample was 11.75% upward movement for Nasion [SD +/- 17.90] and 11.46% downward movement for Gonion [SD +/- 3.25]. Horizontally, the greatest forward movement was for point A, maxillary and mandibular central Incisors, point B, pogonion, Menton, Gnathion and Gonion. There was significant difference between girls and boys in the vertical direction for point B, pogonion, Gnathion and Menton. While in the horizontal direction, significant differences were found for ANS, point A, Apex and tip upper and lower incisor, point B, pogonion, Gnathion Menton, and condylion

Non-surgical treatment approach of severe anterior open bite of an adult: a case report

Case report of an adult female demonstrating severe anterior open bite with skeletal class III malocclusion. The patient was treated non-surgically. The treatment mechanics and results are discussed

Intermaxillary tooth width ratio in a Saudi sample with different malocclusions

The intermaxillary tooth width ratio was investigated in Saudi subjects aged 13 to 20 years. Measurements of permanent teeth from central incisors through first molars in all four quadrants were performed in 40 pairs of pretreatment dental casts. The Bolton s formulae were used to examine the relationship between the maxillary and mandibular teeth. The results showed that the mean and standard deviation of mesiodistal tooth width for the over-all ratio was 91.4 and 1.72, and for the anterior ratio was 76.7 and 1.18 respectively. Further, the present study confirmed previous reports that the Bolton ratio is not affected by the different types of occlusion. When these values were compared with some mentioned in the literature it would appear that Saudis belong to the Caucasoid race
