Mini-implants provided absolute anchorage to bring about significant dental and soft tissue changes in moderate to severe Class II division 1 patients and can be considered as possible alternatives to orthognathic surgery in select cases.

Objective: To compare the treatment effects of maxillary anterior teeth retraction with mini-implant anchorage in young adults with Class II division 1 malocclusion undergoing extraction of the maxillary first premolars with similar patients treated by a fixed functional appliance. Materials and Methods: Thirty-four young adult female patients (mean age 16.5 6 3.2 years, overjet $ 6 mm) with a Class II division 1 malocclusion were divided into two groups: group 1 (G1), in which overjet correction was obtained with a fixed functional appliance (FFA), and group 2 (G2), in which upper first premolars were extracted, followed by space closure with MIs as anchor units. Dentoskeletal and soft tissue changes were analyzed on lateral cephalograms taken before (T1) and after (T2) correction of the overjet. Results: Both methods were useful in improving the overjet and interincisal relationships. Extrusion and mesial movement of the lower molar, together with lower incisor proclination, were noted in G1. G2 showed distalization and intrusion of the upper molar. The nasio-labial angle became more obtuse in G2, while lower lip protrusion was seen for G1. Conclusions: The two treatment protocols provided adequate dental compensation for the Class II malocclusion, but did not correct the skeletal discrepancy. There were significant differences in the dental and soft tissue treatment effects between the two treatment protocols. (Angle Orthod. 2012;82:294-303.)

This pilot exploratory study indicates that machine learning methods can help identify community dwelling older adults with 10/66 criterion diagnosis of dementia with good accuracy in a LMIC setting such as India. This should reduce the duration of the diagnostic assessment and make the process easier and quicker for clinicians, patients and will be useful for 'case' ascertainment in population based epidemiological studies.

During treatment planning it is important to recognize different gingival biotypes and forms, because they can affect the esthetic outcome of the treatment. This review provides an insight into the different gingival biotypes, their response to inflammation and trauma; significance in different prosthodontic modalities like esthetic rehabilitation and implant therapy.
