Effects of Composite Attachments on Orthodontic Clear Aligners Therapy: A Systematic Review

This systematic review aims to highlight the differences between different clear aligner therapies that differ in the presence of attachments or in attachment configuration. Eight electronic databases were searched up to March 2020. Two authors independently proceeded to study selection, data extraction, and risk of bias assessment. The analysis of the results was carried out examining six groups of movements (mesio-distal tipping/bodily movement; anterior bucco-lingual tipping/root torque; posterior bucco-lingual tipping/expansion; intrusion; extrusion; rotation). Five clinical trials were selected and all of them showed a medium risk of bias. Literature showed that attachments mostly increase the effectiveness of orthodontic treatment with clear aligners, improving anterior root torque, rotation, and mesio-distal (M-D) movement; they are also important to increase posterior anchorage. However, some articles showed contradictory or not statistically significant results. Attachments also seem to improve intrusion, but the evidence about this movement, as well as extrusion, is lacking. No studies evaluated posterior bucco-lingual tipping/expansion. Further clinical trials are strongly suggested to clarify the influence of attachments and their number, size, shape, and position on each orthodontic movement.

Aesthetic dental challenges for the paediatric patient

Advancements in material science have contributed greatly towards aesthetic dentistry. However, achieving satisfactory aesthetics for children in the developing dentition poses unique challenges. Challenges include, but are not limited to: (1) patient co-operation; (2) optimum moisture control; (3) continuing gingival maturation and bone growth; and (4) the increased need for minimally invasive and non-irreversible techniques to maintain future treatment options. This article addresses the common paediatric dental aesthetic challenges of uncomplicated crown fractures (ie those confined to enamel and dentine), localized, discrete enamel opacities and intrinsic discolouration of anterior, root canal-treated teeth. Treatment techniques and helpful tips for the general dental practitioner are presented. CPD/Clinical Relevance: This article focuses on common dental aesthetic challenges that present in the paediatric dental population and suggests methods to manage this effectively in primary and secondary care.
