Method for expanding bone crest (1) in order to receive the installation of a final dental implant (4), where the bone crest (1) is expanded using a implant-expander, in other words, a biocompatible and osteoconductive piece that has an expander function. The use of an implant-expander (3) to widen the bone crest (1) has the important effect of said implant-expander acting as a support to the bone and therefore helping to consolidate the fracture of the bone crest (1) and the formation of bone around said implant-expander. The bone generated around the implant-expander (3) is therefore of a high quality. The invention also contemplates the optional correction of the angulation of the alveolus during the widening process, so that the final dental implant (4) and the corresponding dental prosthesis are adequately oriented. It is also an object of the invention to provide a specific design for the implant-expander (3).本發明揭示一種擴大牙槽脊(1)以裝設最後牙科植入物(4)的方法，其中牙槽脊(1)係使用植入擴大物(換言之，具有擴大物功能的生物相容性及骨傳導性零件)擴大。使用植入擴大物(3)將牙槽脊(1)擴寬係具有將該植入擴大物作為骨骼撐體，因此有助於將牙槽脊(1)之裂痕固實且在該植入擴大物周圍形成骨骼的重要效果。在植入擴大物(3)周圍所產生的骨骼因此為高品質。本發明亦在該擴大程序期間視情況地修正牙槽之測角，而將最後牙科植入物(4)及對應牙科假體適當地定向。本發明之一個目的亦為提供一種植入擴大物(3)之特定設計。
