The timing and implant type are also important factors in the implant-prosthetic rehabilitation of cleft lip and palate patients. The highest success rates are found in studies where:

1. a 2-stage procedure was performed with time between augmentation regrafting and implant placement not exceeding 6 months;

2. sufficient bone was present to allow primary stability of the implant;

3. autogenous bone grafts from the iliac crest were used; and

4. implant lengths of at least 13 mm were used in the grafted alveolar site.

Other parameters such as implant surface type may have an influence on the long-term prognosis of the implant, however, the research is limited.

The implementation of implant therapy in combination with alveolar grafts has provided these patients with an effective and viable option to other prosthetic alternatives such as bridges and dentures. Further studies are needed to assess the: long-term success of implants placed in clefts that have received secondary bone grafts; revascularization and resorption of bone grafts; and influence of other implant parameters such as surface characteristics and dimensions on the longevity of this treatment option.





在唇腭裂患者的种植义齿修复中，种植的时机与种植体的类型的选择也是很关键的。成功率高的病例通常是：

1、第二阶段在再移植增大物与植体植入之间不超过6个月；

2、有足够的骨来保证种植体的初期稳定；

3、使用取自髂嵴的自体骨移植；

4、植入牙槽嵴骨移植区的植体的长度≥13mm；

其他的参数例如种植体表面类型可能会影响植体的远期预后，但其研究都是有限的。

种植与牙槽骨移植联合治疗的实施，使患者在除其他的修复手段（桥、可摘）以外，有了一个有效并可行的选择。仍需要长远的研究以评价：在实施了二期骨移植的裂隙区种植的远期成功率；骨移植区的吸收及血管再生；以及其他的一些参数例如：种植体表面结构及尺寸大小对这项治疗方法的寿命的影响。
