Fabricating fixed partial dentures using existing restorations

A technique has been described for utilizing an existing fixed splint in the fabrication of a fixed partial denture to replace splinted teeth that are extracted.     

Minimal interventions for weight control: a cost-effective alternative

Two studies were conducted to evaluate simpler, less intensive interventions for weight control which presumably would be more cost-effective and efficient than a "full-length" behavioral treatment program. In Study 1, participants in a minimal intervention (MI1) program who attended no regularly scheduled meetings and initially only received three simple verbal instructions about how to lose weight, lost an average of 11.1 lb. by 7-month follow-up. Subjects in three variations of a shortened, less intensive, 6-week behavioral weight loss program lost 7.8, 6.5 and 6.3 lb. but did not significantly differ from MI1 subjects in the amount of weight lost. In Study 2, MI2 subjects lost 5.5 lb. compared to subjects in two variations of a full-length program who lost 8.1 and 11.1 lb. by 6-month follow-up. Again, none of the groups significantly differed from each other in the amount lost. It was concluded that a minimal intervention program seems to produce weight loss and to be a cost-effective and efficient method for some subjects. The difference between the two minimal intervention programs may be related to the payment of a monetary deposit; a model for future research was presented to investigate simpler, less intensive interventions in combination with more complex ones in a "stepped-care" fashion.
