Title: Lingual fixed retainers in clinical routine


AIMS: Long-term retention of the orthodontic treatment has been a major challenge even from the early days of orthodontics. Fixed retention has been the method of choice for long-term results, presenting important advantages. The aim of this poster presentation is to present different methods of fixed lingual retention, applied during the clinical routine of our orthodontic practice. Evaluation of the pros and cons is made, both for the clinician and the patient.

METHODS: In all cases presented a flattened, dead soft 8-braided stainless steel wire is used and adhesion is achieved through etching of the surface and the application of a bonding agent and flow resin. In 2 of the methods, preparation of the fixed retention takes place in the dental laboratory prior to the bonding in the patient's mouth. All patients had recently completed their orthodontic therapy and presented healthy periodontal tissues.

RESULTS: Each method applied presents different advantages and disadvantages and comparison is made between them considering the difficulty of application for the clinician, the steps and time needed for completion of the method, the final position of the wire as related to the incisal edge of the tooth and the gum, the discomfort caused to the patient and the impact on the neighboring periodontal tissues.

CONCLUSION: Fixed retention is an essential procedure following orthodontic treatment and there is a variety of application methods for the clinician to choose. Unfortunately, controversy remains in modern literature and there is no agreement for a uniform retention protocol.
