Sinus Lift For Implant
Sinus Lift For Surgery
When implants are put in the upper jaw, it is common to partially fill the paranasal sinuses, which raises the floor of the paranasal sinuses. This will be a sinus lift. In the upper jaw behind the canine teeth are the paranasal sinuses, also known as sinuses. These cavities limit the jawbone’s thickness on the upper jaw’s sides.
When teeth are lost for any reason, the jawbone loses its function and shrinks. The jaw bone is lost not only in width but also in height. As you get older, the maxillary sinus enlarges and sags into the upper jaw. As a result, there is sometimes insufficient bone for implants to be placed.For implants to grow firmly into the bone, it is important that there is sufficient length in the jaw and that the implants are surrounded by bone when placed. There is enough bone for implants to be placed through the floor of the maxillary sinus and into the jaw wall. At this moment, own bone, artificial bone, or a mixture of own bone and artificial bone can be used.
Why perform a Sinus Lift?
Sinus Lift for implant is a surgical technique that increases the bone volume (in height) at the sinus level (upper jaw) to guarantee good osseointegration of the implants in the bone. Thus, when the dental surgeon observes a lack of bone in the patient in the premolars and molars, a sinus filling must be considered so that the jaw bone is high enough to support an implant. (i.e., 8mm). Once the graft has been set, the dental surgeon can position the dental implant in an area where he could not initially do so.The majority of people are eligible for implants. There are several conditions where we cannot implant. You will ultimately make a choice with the help of your dentist. Delays in healing can result in implant failure due to diseases like osteoporosis or uncontrolled diabetes.
What patients is it for?
The Sinus Lift surgery technique is intended for patients with a lack of thickness in the upper jaw, at the level of the molars and premolars (bone height less than 5mm between the bone crest and the bottom of the sinus), which prevents the placement of dental implants.
This lack of bone thickness is most often explained by:
- a long-standing tooth loss that has not been treated,
- loss of bone volume following periodontal diseases,
- a sinus unsuitable for the implant due to its shape or size
- trauma or genetic problems leading to the loss of certain teeth
How is Sinus Lift Performed?
If there isn't enough bone under the sinus, sinus lift techniques can be used to move the implants closer to the back of the upper jaw. Your jaw and your sinuses are separated by the bone. After this surgery, dental restorations usually take between 6 and 12 months to finish.
1.Dental X-ray
Dentists examine your upper jaw to assess the degree of bone loss before doing anything at all. As a result, they completely x-ray the upper mouth
2.Light Sedation
Anesthesia aids patient comfort because sinus lift surgery is minimally invasive. In this stage, we use local anesthesia to numb the region.
3. Maxillary Sinus Elevation
The dentist then gently raises the maxillary sinus cavity. When the sinus membrane is lifted, a hole is left behind that needs to be filled for an implant.
4. Bone Grafting
The maxillary sinus membrane is raised, filling the area with bone graft material. The gum tissue is stitched back together when the dentist seals the graft.
Are You Suffering from Sinus Problem ?
Do you suffer from a lack of bone volume in the maxilla and are concerned about being unable to receive dental implants? During the pre-implant consultation, your dental surgeon may suggest that you perform a Sinus Lift.
Why and when is a sinus lift needed?
If a tooth is lost, the maxillary sinus in this place will sag over time. So, the maxillary sinus gets bigger, but the amount of bone under the maxillary sinus gets smaller. That is annoying because enough bone is needed to place an implant. To make this possible, the nasal cavity will have to be “lifted”—a sinus lift. With a sinus lift, artificial bone is placed in the maxillary sinus so there is enough bone again to implant.
At Virginia Dental Care, we will inform you of the operation’s course and possible complications. In this way, you are assured of good preparation with us. Before the dental surgeon can perform a sinus lift for implant, our dentist takes a CBCT scan to properly map out the bone situation. You can choose to perform the sinus lift before placing an implant or to perform it immediately after each other. It is often recommended that the implant be placed shortly after the sinus lift. If you wait too long, the bone in the upper jaw can start to wear out again.
How is a Sinus Lift performed?
Sinus Lift Steps:
- Assessment of the amount of missing bone
- Incision of the gum and elevation of the membrane
- Injection of synthetic bone into the gum
- Placement of the graft and suturing of the gingiva
- Reformation and calcification of bone
- Placement of the dental implant
The Techniques
- External Sinus Lift (closed sinus lift)
Preferred for large-volume grafts, this technique involves approaching the external wall of the maxillary sinus to obtain wide access with maximum visibility of the operating area.
- Internal Sinus Lift (open sinus lift)
Regarding an internal Sinus Lift, the surgeon accesses the sinus via the coastal route. This technique is reserved for grafts of reduced volume (when the thickness of the residual bone is greater than 5-6 mm).
The duration of treatment:
Generally, 3 appointments are necessary:
- The 1st for the sinus graft,
- The 2nd (6 to 9 months later) for implant placement
- The 3rd (6 to 9 months later) is for the implementation of the implants and the final fitting of the dental prostheses (bridge or crown)
But depending on the patient’s bone volume, the treatment plan can also take place in 2 stages. In this case, the implants are placed simultaneously with the graft. This significantly reduces the duration of the treatment plan.
