Bone augmentation ensures a favorable 3-dimensional position of implants. Onlay grafting is one of the techniques in ridge augmentation, which can be performed with the use of xenogenous blocks.
Three cases of the vertical and horizontal ridge are discussed, which were augmented using xenogenous blocks. The blocks were shaped in a favorable size and puzzled along the grafting area. All the gaps were filled with granular xenografts. The flaps were coronally advanced to obtain primary closure.
An average of 4.2-mm gain in width and 4.2-mm gain in height of the ridge was observed at the implantation stage.
The outcomes of these cases could pave the way for suggesting xenograft blocks for augmenting wide areas of the alveolar ridge on average of 4 mm in width and height in selected cases as an alternative to standard autogenous blocks. Long-lasting xenograft ensures implant and lip support in the esthetic zone.
骨增量可确保种植体获得良好的三维位置。外置植骨是牙槽嵴增量技术之一，可使用异种骨块进行。
讨论3例垂直和水平牙槽嵴增量病例，采用异种骨块进行增量。将骨块修整成合适大小并沿植骨区域拼接。所有间隙均用颗粒状异种骨填充。将瓣向冠方推进以实现一期缝合。
在种植阶段，牙槽嵴宽度平均增加4.2毫米，高度平均增加4.2毫米。
这些病例的结果可为在特定病例中使用异种骨块平均增加牙槽嵴宽度和高度各4毫米的大面积增量提供依据，作为标准自体骨块的替代方法。长效异种骨可确保美学区域的种植体和唇部支撑。
