The stability of the orthodontic and prosthetic results of the treatment of 18 individuals with isolated cleft of the palate, 18 subjects with a complete unilateral and 8 with a complete bilateral cleft was evaluated in an eight-year follow-up period. The subjects were examined at the age of 19 years, after completed orthodontic and surgical treatment, and again at the age of 27 years. After the first examination the majority of the individuals with a complete cleft had at the age of 20 to 21 years been treated with a fixed bridge which was only minimally extended. The width of the upper dental arch at the second bicuspid decreased slightly in the subjects with an isolated cleft of the palate and in those with a bilateral cleft. In the subjects with a unilateral cleft there was a slight decrease of the upper dental arch widths at both bicuspids and at the first molar. In the subjects with complete clefts the slight decrease in upper dental arch widths was accompanied by a slight increase of the number of posterior teeth in cross-bite. The total number of teeth in cross-bite was small, however. On the whole, the upper dental arch was relatively stable during the follow-up period. This was found in the group with bilateral clefts, reconstructed with 5-8 unit bridges, as well as in the subjects with a unilateral cleft who had received no or only minimally extended reconstructions and in the group with an isolated cleft of the palate (no bridge).
在八年的随访期内，对18例单纯腭裂患者、18例完全性单侧腭裂患者和8例完全性双侧腭裂患者的正畸和修复治疗结果的稳定性进行了评估。这些受试者在完成正畸和外科治疗后的19岁时接受了检查，并在27岁时再次接受检查。首次检查后，大多数完全性腭裂患者在20至21岁时接受了仅轻微延伸的固定桥修复治疗。单纯腭裂患者和双侧腭裂患者的上颌牙弓在第二双尖牙处的宽度略有减小。单侧腭裂患者的上颌牙弓在双尖牙和第一磨牙处的宽度均略有减小。在完全性腭裂患者中，上颌牙弓宽度的轻微减小伴随着后牙反合数量的轻微增加。然而，反合牙齿的总数很少。总体而言，在上颌牙弓在随访期内相对稳定。这在采用5至8单位桥修复的双侧腭裂组、未接受或仅接受轻微延伸修复的单侧腭裂患者组以及单纯腭裂组（未行桥修复）中均有发现。
