Treatment for abused children: when is a partial solution acceptable?

Physically maltreated children display a range of serious psychological problems. Despite the availability of effective treatment of similar problems in other populations of children, direct psychological treatment of abused children has rarely been reported. It is argued that such direct treatment, while constituting only a "partial solution" to the problem of child abuse, needs to be addressed through research and application.

The effect of functional appliances on the skeletal pattern.

The findings of some 26 papers covering the results of Andresen and Fränkel appliances, as analysed from cephalometric radiographs, are reviewed. These findings show a high degree of consistency. They have been combined to produce larger samples, and compared with a control group produced from reports of untreated Class II division 1 individuals, with consequent gains in statistical significance. Generally, there is no appreciable holding back of maxillary advancement in either group (although a slight relative reduction in the angle SNA). There is a slight mean increase in mandibular growth, mainly in a vertical direction. This seems similar to that reported by several authors in conventional appliances. There is a wide variation in response.

The effect of two contrasting forms of orthodontic treatment on the facial profile.

The purpose of this paper was to compare retrospectively the effect on the soft tissues of two contrasting forms of treatment for Class II, Division 1 malocclusion. The first group of 30 persons exhibited uncrowded dentitions and were treated without extractions by means of the Andresen activator. No other appliance was used. The second group was also composed of 30 persons. These subjects were treated with the Begg appliance in its classical form. All of the Begg subjects showed varying amounts of crowding and were treated by extraction of four first premolars. It was believed that the Andresen appliance would maintain the incisors in the most labial position possible, while the Begg group with premolar extractions would involve the maximum lingual incisal movement. These groups were compared with a third group of 22 untreated persons who also exhibited Class II, Division 1 malocclusions. The overjets in the treated groups were successfully reduced in both cases by retraction of the upper incisors; in the Begg group only, retraction of lower incisors was also performed. The upper incisors were retracted substantially more in the Begg group than in the Andresen group, but there was only a slight difference within the two groups in the final position of the upper lip relative to a vertical reference line through sella. There was also a slight difference in the lengths of upper and lower lips within the two treated groups. The lower lip followed the lower incisors more closely in the Begg group. Both upper and lower lips "uncurled" in the treated groups and this probably allowed them to be held together with little strain. There was a wide variation in individual response in all three groups.
