Sinus Elevation for Implants - and zygoma Implants alternative
Sinus Lift procedures
Sinus Lift procedures are also called “sinus elevation” and relate to a phenomenon called bone atrophy, or shrinking upper jaw or deficient upper jaw (maxilla) bone. This bone deficiency can be a result of natural anatomy, but is usually caused by extracted or missing teeth in the area. Missing teeth in the upper jaw can cause the jaw bone to shrink, but also the sinus space (air spaces below the upper jaw bone on either side of your nose) to expand and grow into the area. This is called sinus expansion or sinus pneumatisation. It leads to a lack of bone for dental implants. If there is a lack of available bone in the back of the upper jaw, then a sinus lift or elevation may be recommended, if you want to benefit from dental implants.
An effective bone graft procedure or alternative
A Sinus Lift is performed routinely by our dental implant dentists at our Perth clinic. It is a delicate procedure, and our experienced team uses piezosurgery or ultrasonic bone surgery, which is much gentler than traditional surgery methods. It helps us to carry out a sinus elevation successfully, with precision, safety and comfort. As a patient you usually experience very minimal or no post operative discomfort, and may be able to resume most regular activity very quickly.
A sinus lift is a type of bone graft that creates new bone “upwards” in the upper jaw, rather than outwards or downwards. This means that after the procedure, you can’t feel the change in your gums or mouth, because it is internal. This makes healing very comfortable, and allows you to have gentle pressure on the area or wear a denture without disturbing the graft outcomes. This is in contrast to vertical or horizontal bone augmentation or grafting, which builds tissue into the mouth and requires more delicate post operative care.
With sinus lift, you are to avoid flying, drinking through a straw and avoid excessive pressure buildup in the sinuses for at least a few days after surgery, and your dentist will discuss this with you.
Types of Sinus Lift: How does it work?
Sinus lift surgery compensates for shrinking upper jaw bone (sometimes visible as shrinking facial bones), by adding bone to your upper jaw, in the area of your molars and premolars. This is why it’s also called a sinus bone augmentation. The surgery adds bone volume between your maxillary sinuses (on either side of the nose) and your jaw. In this procedure, the sinus membrane is lifted from its base, and in most cases a material is placed below it to hold the space and create new bone development. In effect the sinus is repositioned in a higher position, so that there is room for dental implants below it. Sinus lift procedures in most cases work very predictably with use of bone substitutes only, meaning you often don’t need to have bone taken from any other area to graft to the sinus. We can use a bovine, synthetic, or human bone substitute material, and in some cases only a collagen membrane and PRF, to create new bone formation in the sinus area.
3 Things to know about Dental implants
Having seen many incomplete smiles in my years as a dentist, I have seen the impact that great dental implants can have on a person. From a complete smile to having complete confidence, it is all possible with the right implants. Get a copy of my free eBook to see what you should know about dental implants and achieving that complete smile.
There are two types of sinus elevation procedure: Internal sinus lift (usually where only 1-4mm of extra bone is needed at the time of implant placement) is done through the dental implant space at the time of placement. External/lateral approach sinus lift is done where a larger amount of new bone generation and space for dental implants is required, and can be done through a “side or lateral window approach” either at the time of implant placement, or in preparation for future implants, depending on what is suitable for the case.
Alternatives to sinus lift
For single implants with localised bone deficiency or low sinus position, sinus lift can often be done at the time of implant placement, or a few months before implant placement.
If you have a very atrophied or severely deficient upper jaw (maxilla) bone due to long term missing teeth and denture wear, and you require sinus lift for dental implant teeth replacement, you may need to wait up to a year after a sinus lift before having implants. In these cases, another option may be the use of zygomatic implants, which can bypass the area of deficient bone and attach into the base of cheek (zygoma) bone to avoid any bone grafting or staged treatment.
Why choose Complete?
For a delicate procedure such as sinus lift, you want to know your Perth dental surgeon performs the procedure routinely and with experience. Sinus elevation procedure can sound daunting but is usually a predictable procedure with very minimal discomfort, to facilitate your dental implants where necessary. At Complete Implant and Sedation Dentistry, the team is experienced in oral surgery (dento-alveolar surgery) such as sinus lifting, and our focus is on modern implant and pre-implant surgical procedures under sedation. Practice principal Dr Habibi is awarded a Master of Oral Implantology and is a qualified sedationist. He has successfully performed many sinus lift and bone graft procedures under the comfort of sedation.
