In comparison to untreated individuals, the SNB and gonial angles decreased significantly following chin cup use, whereas ANB, Wits appraisal, SN-ML, N-Me and overjet increased.
In addition, Class III malocclusion of treated patients was significantly improved since there was a statistically significant increase following chin cup use in comparison to untreated individuals to (a) the ANB angle (SDM = 2.48, CI = 1.36 to 3.61, P = 0.000) and (b) the Wits appraisal (SDM = 3.62, CI = 1.32 to 5.92, P = 0.002) as shown in Figures 5 and 6, respectively.
The closure of the gonial angle due to chin cup use is widely supported by the literature as well [2],[12],[36],[39]–[43],[46] and could be partly explained if the direction of the force applied through the chin cup is considered.
Nevertheless, repeated cup use may have subtly damaged the porous surface and it would have been ideal to use new cups for each individual test.
The primary outcomes at six months, including exclusive breast feeding and timing of introduction of solids and "tummy time," were collected by a telephone interview, and those at 12 months, including breastfeeding, cup use, bottle at bedtime, and having food as a reward, were collected by research assistants in the home.
If cutting handles for your trophy cup, use construction paper, which is lighter than cardboard.
