Bone grafting is always accompanying with dental implant in many cases. Because once a natural tooth is lost, the quantity as well as the quality of alveolar bone starts to deteriorate. Thus, most dental implant cases require a bone grafting in order to firmly support the implant. Accurately analyzing the structure of alveolar bone and identifying the cause of tooth loss are essential for performing bone grafting.
It is important to take patients’ medical history, notably such as diabetes and osteoporosis into consider in making diagnosis because it can bring about significant impact on the treatment results. The amount of bone required and the way of operation will be determined through CT scanning. At this moment, wide experiences and capability in this field will play a critical role to make right judgments.
What is Bone Grafting?
Bone grafting is a treatment to transplant bone into alveolar bone in order to firmly support the implant. Autologous, allogeneic, heterogeneous and synthetic bones are commonly used for grafting materials. This treatment includes Platelet–Rich Fibrin
Procedure of Bone Grafting
Examining exact mass and density of alveolar bone where dental implant will be performed. Bone grafting is performed after measuring the amount of bone to fill out and deciding on bone materials and the way of operation.
After successful integration of bone grafting, the location for dental implant operation and the condition of alveolar bone are checked and an optimal size of dental implant is planted.
Wait until successfully connecting the grafted bone to the implant.
Patients should be very careful about oral hygiene during this period.
. Once the prosthetic teeth integrate with the grafted bone successfully, the second operation is performed in which the prosthetic tooth is mounted on top of the implant.
What is Maxillary Sinus Floor Elevation?
Maxillary sinus is anatomical structure in maxillary molar area where dental implant is actually performed. A tooth loss causes pneumatization and lack of alveolar bone in maxillary molar area. It is necessary to augment the mucous membrane to create a space for alveolar bone in maxillary sinus. This procedure is called Maxillary sinus elevation. Maxillary sinus with enough blood supply result high successful rate of bone graft.
Dentists examine how much part of alveolar bone in maxillary sinus is remained through exact CT screening in order to check the possibility of dental implant.
A crestal incision is made exposing the crestal ridge of the maxilla. Gently raise the sinus membrane from the sinus floor with bone grafting material, and place implants. Then, absorbent membrane is covered and sealed with thread.
Once grafted bone and the implanted dental are securely engrafted, place a prosthetic dentistry to complete the procedure.
1. Does bone grafting must be done for any dental implants? When can an implant be placed after the bone grafting?
Bone grafting is done when there is no enough space in the alveolar bone for performing dental implant. It would cause various side effects such as nerve damage or perforation in maxillary sinus when dental implant performs on an insufficient bone mass. In addition, dental implant could fall out in the grafting process. As a result, it is very important to lay the foundation for performing dental implant beforehand when the mass of alveolar bone is insufficient. Depending on the condition of alveolar bone, implants can be placed immediately, or 2~3 months after the bone grafting
2. Does dental implant hurt much?
In general, it is not painful except the moment when the anesthetic wears off. However, it can be varied depending on operations. Pain can be followed by: difficult operation with longer surgical time; operaion with more procedures; operation with heaviness of blood loss. Although maxilla implant is generally more complicated than mandibular implant, patients would not feel much of discomfort. Hus-hu dental clinic uses so called “No Pain” device when anaesthetizing especially for patients who have a greater fear of pain.
3.Post bone grafting Management
First 2-week after the bone grafting is a critical period. Patients may experience light bleeding on the day of surgery. Patients should try to swallow instead of spitting the blood out in order to stop bleeding. In the case of bone grafting implant, patients should take prescribed medication for 3 days, and avoid drinking alcohol and smoking cigarettes. Notably, stop smoking is must do for patients because smoking disrupts oxygen and nutrition supply and hinders bone creation at the treated area. Massaging the area with an ice-pack helps relieve both swelling and pain when pain persists for 2~3 days. Patients should avoid doing strenuous exercises and taking a hot shower or bath. It is recommended to gargle with a mouthwash instead of brushing teeth, have a soft food and chew foods with non-treated tooth.
4. Post Maxillary Sinus Floor Elevation Management
It is advisable for patients to wipe their nose instead of blowing when having nosebleed for 2~3 days after operation in maxillary sinus. Do not blow one’s nose, use straws and open mouth when sneezing. All these actions cause pressure increases in the treated area and lead patients to have a secondary infection due to increasing foreign substances inside nose. Drinking and smoking should be avoided and leaving treated area without touching. It is recommended to gargle to disinfect two times a day. Maxillary Sinus Floor Elevation could require treatment of otolaryngology because the operation elevates the structure of naris. By considering all of them, patients should refrain from doing strenuous exercises and taking a sauna for 3 days after the operation.
