Usually, volume loss occurs in the jaw bones as a result of advancing age and teeth extraction at an early age. Having a sufficient amount of bone in the jawbone causes sufficient compression during the application of the implant. If there is sufficient bone tissue, this situation can be overcome by placing bone tissue or artificial bone from the person's own forehead into the jaw.
What are the areas where bone graft will be taken?
Bone graft can be taken from many areas in the body. Where the bone graft will be taken is often determined by the need for the required graft. Bone grafts can be taken from the chin tip, chin and facial area, or intraoral area. If a large amount of bone graft is required, these are taken from the leg or hip. Bone grafting is not always used before the implant procedure, but sometimes to repair bone losses caused by periodontal diseases, tumors, cysts, etc. Bone grafts are a procedure that will repair all types of bone loss in the jawbone.
Jawbone powder is sometimes used from animal sources or synthetically.
In which cases are jaw bone powders used?
In cases where there is not enough bone volume to place an implant, in cases where the extraction site needs to heal without loss after tooth extraction, in cases of cyst or It can be used to support that area and ensure new bone formation after formations such as tumors are removed. The area can be made suitable for implants by elevating the sinus floor (sinus lift) and filling it with bone powder.
What are bone grafting procedures?
Expanding the jawbone (crest):
Jawbone grafting is a method used to prepare for implant placement, especially in an area that has been toothless for a long time. As the toothless area undergoes bone loss over time, bone volume loss occurs. For the support of the implant to be placed in this area, bone grafts are added to the crest to raise and widen it, thus providing adequate bone support for the implant.
What is sinus lifting? ;
There are hollow air spaces at the back of the cheek and above the upper molar tooth roots, which we call maxillary sinuses. Our tooth roots extend into this space. When teeth in this area are lost, sometimes there is not enough bone thickness to apply implants. In such a case, it is necessary to increase the bone thickness there. This procedure is called sinus grafting or sinus lifting. In the sinus lifting procedure, the membrane covering the sinus floor is removed and bone powder is placed underneath. Thus, the sinus floor is elevated. It may take approximately a few months for the graft to mature. Only after this stage, the implant can be placed in place.
Mandibular nerve repositioning (repositioning):
Bone in the lower jaw rear teeth area If the loss occurs excessively, the nerve may be damaged during implant placement. To avoid this complication, the position of the nerve can be changed to move it away from the implant area before the implant is placed.
In this method, the gum is separated and removed from the bone, a piece of the bone is removed, the mandibular canal is reached, and the mandibular nerve is moved to a lower place so that it does not come into contact with the implant. is moved. Thus, the implant is placed safely without damaging the mandibular nerve. The gap in the area where the nerve was removed is filled with bone graft and the gap is closed.
What Should I Pay Attention to After Bone Grafting? Is the Grafting Procedure Painful? What Foods Should I Eat After the Procedure?
The procedure is usually performed with local anesthesia. There is no pain during the operation. After the operation, you should use the medications prescribed to you regularly, as recommended by your doctor. Grafting procedures are delicate applications. You must protect the procedure area from trauma. You should avoid foods that are hard and require excessive chewing power. It may take up to 4-5 months for the placed graft to integrate with the tissue.
