Unique Solutions for Complex Cases
Dental Implants For Patients With Bone Loss
Bone loss patients are considered complex cases to treat in the implantology world. They lack bone to sustain a dental implant and their restorations require special dental implants and bone augmentation procedures.
Dr. Eduardo Crooke is an international reference in the field of advanced surgery using guided and GPS controlled procedures that result in painless and minimally invasive treatments. This technology together with his training on special dental implants, allows him to maximize the existing bone and avoid the need for bone grafts.
After a CBCT scan and an implant study, we will be able to determine the need for bone grafts and the type of dental implant needed.
Effortless Smiles: Graftless Solutions for Faster Tooth Replacement
When to apply sinus lift?
We recommend the sinus lift for patients who have lost their teeth for a long time and have significant bone resorption.
CBCT or CT Scanner is required to determine if a sinus lift is feasible and the appropriate technique. With this diagnostic test, we will assess the density and volume of the bone.
A sinus lift surgery requires technique and experience, so it must always be performed by an expert in the field for the treatment to be successful.
Two Different Sinus Lift Techniques
1. Atraumatic sinus lift
CBCT scanner must show at least 4 mm of bone for this technique.
During the drilling phase for the implant placement, we will raise the sinus membrane to impact the bone we will graft
The amount of bone will depend on each patient. It must be enough to make the bone cover the implant to keep it steady.
2. Surgical sinus lift
When patients do not have the necessary 4 mm of bone to perform an atraumatic elevation, follow the Surgical Sinus Lift technique.
This technique creates an access window through the lateral sinus wall. To make this window, we will detach the gum from the bone. The cavity will allow to elevate the membrane and then fill the sinus with bone graft material.
Thanks to this meticulous surgery, implants can be placed in areas with little residual bone height, where otherwise it would be impossible.
Grafts and Bone Regeneration
Grafts and Bone Regeneration increase bone volume in patients with bone loss to place an implant in that area in the future.
When is it appropriate to use grafts and bone regeneration?
Guided Bone Regeneration
The most complex treatment in bone regeneration and usually avoided due to new dental implant techniques.
After placing xenografts or autografts, we use collagen membranes that act as a barrier to allow bone regeneration.
The healing time of this treatment will be at least six months.
Bone graft
The surgeon will use a bone grafting biomaterial and graft it onto your jaw bone. You will probably have to wait several months until the graft creates enough new and strong bone.
Once the bone is mature, the implant can be placed and will remain stable and secure in a strong jaw bone.
If only a minor bone graft is needed, your dentist could choose to place the implant during the same graft surgery.
We usually apply Plasma Rich in Growth Factors to get a faster healing. We can also combine the bone graft with the tissue graft to get better results.
Both procedures take place in very localized areas and are performed long before placing the implants.
Depending on whether a bone/gum graft or bone regeneration is chosen, the patient will have to wait between 4 to 9 months until the implant is placed.
Benefits
- The material used is biocompatible.
- Obtaining high quality bone which is strong
- enough to support the implant.
Different solutions adapted to each case
Custom Titanium Mesh
It’s an alternative when zygomatic implants aren’t viable due to issues like sinusitis. After an examination and CT scan, a custom titanium mesh is designed and anchored to the patient’s bone. Provisional teeth are fixed on the surgery day, and final teeth are placed after mesh adjustment.
Benefits include safe, minimally invasive surgery without bone grafting or sinus movement, resulting in significant time savings compared to grafts.
Zygomatic Implants
Zygomatic implants are much longer than conventional ones. They anchor in the zygomatic bone instead of the upper jaw.
When is it appropriate to use zygomatic implants? When the upper jaw shows severe bone resorption. Generally, in patients with a lack of teeth for many years. When the patient has suffered from aggressive periodontal disease. In cases where the patient wishes to avoid the necessary waiting time after a bone graft.
Grafts and Bone Regeneration
The maxillary sinus floor, situated above the upper back teeth, is restored to its original position by adding a bone substitute, a procedure known as sinus floor bone augmentation or ‘sinus lift.’
If the patient’s bone is thick, we can place the implant immediately; otherwise, a six-month wait is needed for bone graft maturation before implantation, increasing maxillary height with artificial bone for dental implants.

On your first consultation
Firstly, we will do a CBCT scan which is a three-dimensional x-ray in order to measure your bone density, and also to check the health of your remaining teeth and gums.Afterward, we use special software called DTX for better accuracy and predictability of our diagnosis and treatment plan. Depending on the planning, surgery will be guided or navigated, which allows us to optimize the bone and avoid unnecessary bone augmentation making the treatment minimally invasive. Also, there are some cases that we can solve with atraumatic bone grafts at the same time as we place implants. 97% of the cases we can finish with fixed teeth on the same day of the surgery.
On your second visit
After a healing period of three months, firstly we will check your dental implants to confirm that the healing is as expected, and we will make final digital impressions. Our specialist in prosthesis will do any changes or adjustments if necessary. After this, we will be able to produce and place your final teeth, and you can leave with your perfect new smile.
