[A quantitative study on mandibular incisor point border movement between the immediate complete denture wearers and the second complete denture wearers]
The mandibular incisor point border movement orbits of 20 patients wearing immediate complete dentures for 3 months and the same patients wearing the second complete dentures for 3 months were raced by SGG then measured and analysed.The results showed that the ranges of mandibular incisor point border movement of patients wearing immediate complete dentures for 3 months were significantly narrower than those of the same patients wearing the second complete dentures for 3 months (P<0.01).The ratio of the former to the latter was only 59.00%-69.96%.It could be concluded that the ranges of mandibular incisor point border movement of immediate complete denture wearers were limited.Thus the immediate complete dentures were transitional dentures and only used for treating purpose.The patients must have another pair of complete dentures after 3 months interim.
