I have a case with early crestal bone loss. Can I use PRF?
Discussions related to bone grafting during dental implant procedures.
Patient returned to me after six and half months for second stage surgery and I observed significant vertical (angular) bone loss around the implant.
How can one salvage this bone loss in this dental implant case?
I would be interested in readers views on the use of irradiated human bone from a bone bank as an onlay block graft to augment a narrow ridge in the upper incisor region prior to implant installation.
Seems as if “hardened” bone had not formed. Any ideas as to what went wrong in my technique?
But clinically the crowns were not fully seated. I noticed this 1-year after the insertion. I am starting to see some bone loss around the implants.
Analysis of study models and radiographs indicates that with implants, the crown height of the crowns on those implants would be in a range of 15mm.
As you can see from the radiograph, there is limited mesiodistal space and there is considerable loss of vertical bone height.
The alveolar ridge buccolingual width was only 5mm so the patient had an iliac crest graft to increase the width.
The recent CBCT shows that all 3 bone grafts have failed. The patient is asymptomatic and the implants are not mobile.
Vertical and horizontal bone growth was achieved with SynOss Putty with the aid of the MatrixDerm barrier membrane. Dental implants were able to be placed and primary fixation was achieved in the grafted site.
I have no experience with doing at lateral sinus lift, especially with sinusitis like this case.
I have a patient who received radiation treatment for squamous cell carcinoma of the mandible following a hemimandibulectomy. After 5 years post-treatment, the patient then received a vascularized bone graft.
This case shows the use of Synoss Putty and MatrixDerm Membrane to support new bone formation in a larger sinus lift procedure to enable placement of dental implants.
Would it be possible for me to increase the bone volume of the alveolar ridge by decorticating the cortical bone and then placing PRF alone? Could the PRF hold the space to convert to bone?
I discovered that there had been a rupture in the Schneidarian membrane and a load of allograft has been displaced into the posterior sinus cavity.
The patient returned for the 1-year follow up and I noted significant bone loss around the implant in #30 site.
I have treatment planned a patient for installing an implant and doing a bone graft at the same time. The problem is that the alveolar ridge will require augmentation in both vertical and horizontal dimensions.
What is the best time to perform gingival grafting in order to increase the zone of attached gingiva around dental implants?
Can I put at Collaplug [resorbable collagen] on top of the membrane or should I leave it as it and allow it to heal?
Is it better to get partial coverage over the wound site and membrane with minimal tension or is it better to completely cover the membrane with a flap, even if it is under some tension?
I am not sure when where I should use Cortical bone particulate for grafting and where I should use Cancellous bone.
How do we know which bone graft material is best for each surgical situation?
How is the PRF Kit from Choukroun any different than the conventional centrifuge machine?
For a case that has had significant bone grafting prior to implant placement, do you find separate implants with individual connectors easier to maintain in the long run?
