H8 Clinical and biological characteristics of retainer and not-retainer hypertensive patients

Clinical pearl: LingLock--the flossable fixed retainer.

The present article describes a new product for long-term retention of the lower dental arch. The LingLock is a fixed bonded retainer from canine to canine in the lower front made up of separate, but co-working retention elements in the ceramic material aluminium oxide (Al2O3). The LingLock retainer enables the patient to floss the teeth in a regular manner in the actual retention area.

A functional maxillary wraparound retainer.

JCO/FEBRUARY 2004 H retainers with Adams clasps or labial wires crossing the occlusion can create interferences that may lead to bruxism or disc displacement1-3 (Fig. 1). On the other hand, if a wraparound retainer is fabricated without crossover clasps, it is difficult to adapt the round wire closely enough to the anterior dentition to provide adequate mechanical retention, especially in patie...

A randomized clinical trial of thermoplastic retainer wear.

The purpose of this study was to determine whether thermoplastic retainers need to be worn full-time for a limited period or whether part-time wear from the outset is adequate to maintain tooth position, arch form, and occlusion. This study was a randomized clinical trail, conducted in a district general hospital. Sixty-two participants were enrolled in the study. Group 1, full-time wear, consi...

A prospective clinical evaluation of mandibular lingual retainer survival.

Bonded retainers are considered reliable, independent of patient co-operation, and highly efficient. However, most studies regarding the survival of retainers are retrospective. The aims of this investigation were to prospectively evaluate the failure rate of bonded lingual retainers, the influence of direct or indirect bonding procedures on survival, and to determine the distribution of failur...
