Gingivala retraktioner och ortodontisk behandling – Hur kan man förebygga och när ska man behandla?
Ortodontisk behandling ska förbättra både funktion och estetik, men utvecklingen av gingivala retraktioner kan framför allt påverka det estetiska resultatet negativt. I denna föreläsning ges en översikt över riskerna för gingivala retraktioner i samband med ortodontisk behandling, indikationerna för eller emot kirurgisk korrigering av mjukvävnadssituationen samt bedömningen av den optimala tidpunkten för detta i relation till ortodontisk behandling.
Ortodontisk behandling hos patienter med parodontit – Hur ska vi planera vår behandling?
Patienter som lider av parodontit drabbas ofta av att deras tänder flyttar sig, roterar och/eller elongera på grund av fästeförlust. Därför frågar dessa patienter ofta före eller senast efter parodontal behandling om det finns möjlighet att korrigera de oftast oestetiska tandställningarna. Men är ortodonti överhuvudtaget möjligt för patienter med parodontit? Denna föreläsning kommer att behandla just denna och andra viktiga frågor, till exempel när är det bästa tillfället att påbörja ortodontisk behandling, hur mycket konservativ och kirurgisk parodontal behandling bör genomföras före ortodontisk behandling och vad måste man tänka på under och efter ortodontisk behandling?

Thursday morning: The Value of Ortho-Perio treatment
Orthodontics can play an important role in improving the prognosis of periodontally degenerated dentitions, in preserving teeth, restoring function, and bringing back the smile. Aesthetics is motivation. Planning and interdisciplinary communication are key. Long-term maintainable results with normal function and improved aesthetics are the goals. What are the orthodontic challenges and possibilities in the management of dentitions with reduced periodontium and often missing teeth? The presentation will focus primarily on planning, biomechanical appliance design and the interdisciplinary approach to treatment with long-ter, follow up.
Thursday afternoon: Extraction in CL II treatment
Extractions are often debated and questions are; why do we extract and when are extractions needed? Indications can be biological and aesthetic, aiming to achieve good occlusion and a harmonious position of the incisors, not only within the face, but also within the alveolar bone. The mandibular gingival phenotype and the alveolar bony envelope are determining factors in the decision to extract.
Space closure can be performed on continuous archwires or with sectional and segmented techniques. The choice of approach depends on the initial malocclusion. The objectives are to maximize the effects while minimizing the side effects of the appliance. Furthermore, anchorage control is required from the beginning of treatment and sometimes TADs can be helpful.
The lecture will focus on:
* When to extract: biological and aesthetic indications
* Space closure techniques using sectional and continuous archwires
* Predictability and anchorage control during space closure
