SINUS LIFT And Bone Grafting For Dental Implant – Kolkata , India

A maxillary sinus floor augmentation procedure[1] (sometimes known informally as a sinus-lift or sinus procedure) is a surgical procedure performed by an appropriately trained dentist or dental specialist to increase the amount of bone in the posterior maxilla, or upper jaw bone.

While there may be a number of reasons for wanting a greater volume of bone in the posterior maxilla, the most common reason in contemporary dental treatment planning is to prepare the site for the future placement of dental implants.

Sinus augmentation (sinus lift) is performed when the floor of the sinus is too close to an area where dental implants are to be placed. This procedure is performed to ensure a secure place for the implants while protecting the sinus. Lowering of the sinus can be caused by: Long-term tooth loss without the required treatment, periodontal disease, trauma.[2]

Bone Grafting & Dental Implants – Kolkata
Bone grafting is a procedure, which may be required either after tooth extraction, before dental implant placement as in a sinus lift, or during dental implant placement. In this section we will discuss the purpose of a bone graft, the different types of materials used for grafting as well as the cost of bone grafting.

Purpose of a Bone Graft

The main purpose of bone grafting is to preserve or increase the amount of the bone that is present in the surgical site. Bone grafting is commonly completed after tooth extraction or during a sinus lift procedure. After the grafting material is placed it is resorbed by the body and replaced with our natural bone. This will either stabilize or slightly increase the level of bone.

After a tooth is removed and the extraction site is allowed to heal on its own, the vertical height of bone will naturally decrease due to alveolar bone resorbtion. By placing a bone graft we are able to stabilize the alveolar ridge, the bone that holds the teeth in place, which means that after the tooth extraction site heals the bone height should be similar to pre-extraction levels.

Bone grafting during a sinus lift procedure will increase the amount of bone available for dental implant stabilization. Without the graft, part of the dental implant can sit in the nasal sinus cavity without any support. This could lead to potential failure of the dental implant in the future. Another common use of bone grafting is to fill in any structural bone defects during implant placement surgery. This allows the surgeon to smooth out the bone circumventing the dental implant.

A less common use of bone grafts is to repair any defects in the natural bone, which occurred either naturally or were caused by the surgeon.
