Sinus Lift Operation
Sinus augmentation is actually a combination of a sinus lift operation and a bone grafting procedure.
The most popular techniques that oral surgeons use for performing a sinus lift operation are:
Preparation of a sinus lift operation
If an autogenous bone graft will be taken from the patient's chin the surgical procedure can be at the same appointment as the sinus lift. If the bone graft has to be taken from the patient's hip the procedure must be performed in a hospital. For sinus augmentation / sinus lift procedures many dentists prefer the use of allografts or xenografts in order to 'save' the patient from one more surgical procedure.
Sinus lift operation - The sinus lift surgery techniques
Today, there are several surgical techniques developed for a sinus lift procedure. Dentists decide which is more suitable for each patient based on their training and the characteristics of the individual case. The most commonly used techniques for sinus lift surgery are:
Technique 1. Lateral Window approach - Traditional Approach
Technique 2. The Osteotome approach - "Internal Sinus Lift Procedure"
The technique is used when the depth of the jaw is enough for placing a stable implant and only little extra bone (1-3mm) is needed in order to prevent sinus perforation. This type of sinus lift procedure is less invasive causing less surgical trauma than the 'lateral window' approach. Another advantage of the 'internal sinus lift' technique is that it can be done at the same time the dental implant is placed.
Sinus lifts performed with either of these techniques have been shown to greatly increase the success rate of dental implant procedures.
