Healthy bone structure of life shaped jaw maintain aesthetic soft tissue around natural teeth and create a framework to support the external appearance of the soft tissue around the implant .
   Lack of alveolar bone , especially in the upper jaw due to bone resorption after tooth extraction can lead to problems of function and aesthetics , these issues need to use tricks to increase the volume of re-establishing the afternoon original direction around tooth loss . Bone regeneration techniques have significantly increased the ability to regenerate functional and aesthetic dental implant restoration by the defective function of life back to its original size , which helps to achieve the implant placement optimum results and increase the reliability of implant therapy and is considered one treatment method concern .
   Restructuring live in the jaw bone can be classified according to the results , both functionally and aesthetically . Jovanovic has split the position in the oral cavity into the position in relation to aesthetics - requires sufficient bone structure ( bone peri-implant soft tissue support to form a convex curved shape naturally ) to help achieve the aesthetic and functional results , and the non - aesthetic -related positions require adequate bone support to ensure success in the long run function .
   Bone structure underneath affect the shape and appearance of the surrounding soft tissue . Unfortunately, in the front of the upper jaw bone structure undergoes rapid shrinkage target after tooth extraction . It takes about 25 vol% in the first year and take up to 40-60 % width in the first 3 years after tooth loss . So many bone regeneration techniques have been introduced to help restore function defects lives . The volume of tissue recover lost hard underneath can be done before or simultaneously with implant placement , which helps to maintain and support not only supported restorations on implant aesthetics but also supports the structure of the related items .
   The changes in bone in the upper jaw type requires different processing methods , and each class size bone defects specifically affect the choice the most suitable graft . For example , small defects live content suggested graft material used simultaneously with implant placement procedure , while the defective function horizontally live in moderate require the use of graft capable prognosis better results as autologous bone grafting treatments according to each stage as a bone graft prior to implant placement . In case of defective function of vertical living and horizontal serious , need to use the tool more complex regeneration that can predict results better bone graft .
   There are many advantages of technology in the bone graft in the mouth . One of the current advances in bone grafting technique involves the use of bone-type proteins ( BMPs - Bone morphogenetic Proteins ) , such as BMP - 2 , have the ability to stimulate bone formation and increase density bone through the process of target and slow restructuring . BMP - 2 helps to increase cell division of stem cells in place to induce mesenchymal cells in the undifferentiated transplant . These cells can be transformed into osteoblasts , created by cell division pattern appropriate , and begin the process of forming the skeleton . This process is called mitosis mechanisms shaping diversity to stimulate healing of bone tissue . It can become an ideal bone graft in the near future .
   The advantages of the technique was also included in the manufacturing process of membrane guided bone regeneration , these strengths have been focused primarily on improving the phy
