Maxillary skeletal and dental growth results in dramatic changes in all three dimensions during active growth. Experimental evidence and the behavior of ankylosed teeth suggest that an osseointegrated object remains stationary in the bone surrounding it and does not move or adapt to bone remodeling. Growth changes may result in the burying or loss of implants depending on the placement site. Hence, implants placed in the early mixed dentition have a poor prognosis of continued usefulness through puberty. When placed early, implants may disturb growth or have to be replaced. Implants placed during late puberty or early adulthood have the best change for long-term usefulness.
在生长活跃期,上颌骨骨骼和牙齿的生长会在所有三个维度上导致显著变化。实验证据和强直牙的表现表明,骨整合物体在其周围的骨中保持静止,不会移动或适应骨重塑。根据植入部位的不同,生长变化可能导致种植体被埋入或丢失。因此,在乳牙混合早期植入的种植体在青春期后继续发挥作用的预后较差。早期植入时,种植体可能会干扰生长或必须更换。在青春期后期或成年早期植入的种植体长期发挥作用的可能性最大。
