Bottom retaining flaps may also be provided at the heel cutouts to hold the bottom portions of the bottles in. Downwardly folded retaining flaps are connected to the transverse edges of bottle neck openings and engage opposite sides of an associated bottle neck to hold the bottle neck in place.

The appliance has full palatal acrylic coverage standard. A wrap-around carrier for packaging necked bottles. In addition, it was shown that the T-Scan is a reliable apparatus for analysis of relative force. A support wire is placed in the bicuspid area to maintain vertical support. In conclusion, there were no significant net changes in occlusal forces or areas after 6 weeks of comparison between the wrap-around and clear overlay retainers following orthodontic therapy.
An independent sample (15 subjects) showed high intraclass correlations ( r > 0.90) between replicate measurements of relative force, indicating low technical errors when multiple measurements are used.
During T 0– T 1, the occlusion with clear overlay retainers showed a significant decrease in posterior surface area contact ( p 0.05). Assessments were made utilizing the T-Scan II (Tekscan, Inc., 307 West First St., South Boston, MA 02127) method of occlusal analysis at 3 time periods T 0, at debond all subjects received lower fixed canine to canine retainer and upper clear overlay retainers T 1, 2 weeks later 14 subjects received wrap-around retainers and the clear overlay retainer group was checked (18 subjects) T 2, occlusal contact assessment 2 months later for both groups. clear thermoplastic retainers (CT) are more comfortable than wrap-around retainers (WA),6,7 or that comfort does not differ between CT and Hawley retainer.8. A good choice for patients with very tight occlusion where crossing over the occlusion is undesirable, or when some settling of the occlusion is desired. Total 32 subjects, randomly assigned to two experimental groups, a clear overlay group and a wrap-around retainer group, were followed to assess occlusal changes. CONCLUSIONS: In conclusion, the results suggest that the circumferential comfortable retainer (CCR) might facilitate patient compliance and thereby improve the maintenance of the fixed orthodontic treatment outcome.A prospective study to evaluate short-term changes in occlusal force and contact surface area associated with retainer wear. Comparing gagging sensation, the CCR group had lower values than the CWR group but there were no statistically significant differences between groups (p = 0.146). RESULTS: Comparing distorted speech and discomfort, the CCR group significantly had lower values than the CWR group (p < 0.05).

The Mann-Whitney test was used to test the hypothesis that there was no difference between the two retainers.
A questionnaire that had a visual analog scale (VAS) which consists of a 100-mm horizontal line with 2 end-points labeled "no discomfort" on the left and "worst discomfort" on the right, with regard to distorted speech, gagging sensation and discomfort, was administered to patients after 4 weeks of retainer wear. Welcome to our factory customized Wrap Around Retainer, we will provide customers with oem service. METHODS: Sixty-six orthodontic patients ( male, 23 female, 43 mean age, 23.42 +/- 10.19 years) who received orthodontic treatment with fixed orthodontic appliances were randomly assigned to two groups after debonding, a conventional wraparound retainer (CWR) group that fully covers the palate with an acrylic plate and a highly polished surface, and a circumferential comfortable retainer (CCR) group which has a horseshoe shaped base plate with three folds on the anterior region. Wrap Around Retainer Laboratory - Made in China - NSDL. ABSTRACT OBJECTIVE: The aim of this study was to illustrate the circumferential comfortable retainer (CCR) as a removable maxillary retainer with good potential patient compliance and to evaluate the discomfort of the retainers including distorted speech, gagging sensation and appliance discomfort.
