Orthodontic retention aims to maintain the teeth in their corrected positions after the completion of orthodontic tooth movement. Teeth have a tendency to return towards their initial positions due to tension in periodontal fibres, particularly those around the necks of the teeth (interdental and dento-gingival fibres). Due to remodeling of the periodontal fibers the first 8 month post orthodontic treatment are crucial.Therefore, bonded retainers have become increasingly popular to prevent unwanted relapse and enhance stability. Longer-term retrospective studies of the effects on periodontal health have shown that, significant deterioration in any periodontal or dental health parameter was not found even though there is increase in accumulation of dental plaque and calculus in subject with bonded retainer 15 years after treatment In recent years, however, unexpected complications like tooth movement, torque changes and inclinations have also been described during orthodontic retention with fixed lingual retainers.Hence, the primary aim of this study was to evaluate the impact of different lingual retainers on periodontal health and stability.

In recent years, there has been a growing demand for aesthetic orthodontic treatments, leading to the rise in popularity of clear aligners. These aligners offer a discreet and convenient alternative to traditional braces, but certain tooth movements, such as extrusion, remain challenging. Extrusion requires precise and stable force application, which clear aligners alone may struggle to achieve. To address this, attachments-small, tooth-colored composite resin pieces-are strategically placed on teeth to enhance aligner grip and improve force transmission. Various attachment designs exist, each with unique benefits for specific movements like extrusion. This systematic review aims to analyze the efficacy of different attachment designs in generating extrusive forces. By examining studies such as randomized controlled trials and FEM studies, the review seeks to provide evidence-based guidance for orthodontists. The goal is to enhance treatment outcomes, improve patient satisfaction, and offer clinicians valuable insights into optimizing clear aligner therapy through effective attachment selection.

This systematic review aimed to evaluate the accuracy of clear aligners in achieving incisor torque during orthodontic treatment. A 10-year data search was conducted based on specific inclusion criteria, such as randomized control trials, cross-sectional studies, and FEM studies involving patients undergoing aligner treatment. Out of 291 studies, 8 met the inclusion criteria and were included in the review.The review found that clear aligner accuracy in achieving programmed incisor torque varied, with average success rates as low as 41%. Power ridges and attachments emerged as essential tools, improving torque control but requiring over-correction to counteract torque loss. The findings highlight the need for further research and optimization to enhance clear aligner performance in orthodontic treatments.

Gr ce l'invention du collage, le traitement orthodontique est devenu plus courant, diverses techniques de traitement ont t mises au point et la dur e du traitement s'est raccourcie avec la diminution du nombre de rendez-vous. La chaleur g n r e pendant le d collement a t associ e des l sions pulpaires dans des tudes sur les proc dures de d collement et de nettoyage des adh sifs. Quelles que soient les m thodes de d collement et de retrait de l'adh sif utilis es, les diff rentes techniques de d collement peuvent entra ner des alt rations de la surface. Les modifications de surface apr s la pose de brackets sont importantes car la surface externe de l' mail contient plus de min raux et de fluor que les couches plus profondes.

Durch die Erfindung des Bondings sind kieferorthop dische Behandlungen h ufiger geworden, es wurden verschiedene Behandlungstechniken entwickelt, und die Behandlungsdauer hat sich verk rzt, da die Anzahl der Termine abgenommen hat. Die beim Debonding entstehende Hitze wurde in Studien ber Debonding- und Adh sivsanierungsverfahren mit Pulpasch den in Verbindung gebracht. Unabh ngig von den verwendeten Methoden der Adh sivabl sung und -entfernung k nnen die verschiedenen Debonding-Techniken zu Oberfl chenver nderungen f hren. Oberfl chenver nderungen nach Brackets sind von Bedeutung, da die u ere Oberfl che des Zahnschmelzes mehr Mineralien und Fluorid enth lt als die tieferen Schichten.

Grazie all'invenzione del bonding, il trattamento ortodontico diventato pi comune, sono state sviluppate varie tecniche di trattamento e la durata del trattamento diventata pi breve, poich il numero di appuntamenti diminuito. Il calore generato durante il debonding stato collegato a danni pulpari in studi sulle procedure di debonding e di pulizia dell'adesivo. Indipendentemente dai metodi di debonding e rimozione dell'adesivo utilizzati, le varie tecniche di debonding possono provocare alterazioni della superficie. I cambiamenti della superficie dopo l'applicazione dei brackets sono significativi perch la superficie esterna dello smalto contiene pi minerali e fluoro rispetto agli strati pi profondi.

Devido inven o da colagem, o tratamento ortod ntico tornou-se mais comum, v rias t cnicas de tratamento foram desenvolvidas, e a dura o do tratamento tornou-se mais curta medida que o n mero de consultas foi diminuindo. O calor gerado durante a descolagem foi associado a danos pulpares em estudos sobre procedimentos de descolagem e limpeza adesiva. Independentemente dos m todos de descolagem e remo o de adesivos utilizados, as v rias t cnicas de descolagem podem resultar em altera es superficiais. As altera es superficiais ap s colchetes s o significativas porque a superf cie externa do esmalte cont m mais minerais e fl or do que as camadas mais profundas.
