I am working in a practice where one of the dentists a resorbable collagen wound dressing as a substitute in guided bone regeneration for a true resorbable collagen membrane.
Discussions related to bone grafting during dental implant procedures.
The posterior alveolar ridges are thin and lacking in bone volume. What are your recommendations?
I would like to open a discussion about the grafting of a 1 or 2 ( or 3, for that matter) walled defect/sockets.
On the 1 month recall the healing abutments were exposed. I changed the healing abutments. The radiograph showed rapid bone loss around #18.
Since the extraction was done more than a year prior to the visit, more than 50% of the bone volume was lost buccolingually.
Seven months after the implant operation I saw 2 areas with bone resorption and one suspicious area that looks to me like an abscess.
My question is on a subsequent visit, I would like to bone graft this site in preparation for a dental implant, but I am not sure exactly how to go about it.
Unfortunately during the surgical exposure, the sinus membrane suffered multiple tears which I thought were non repairable.
In my radiography class we took full mouth series on each other. That’s when I saw the bone loss around my all of my implants. I made an appointment to see the periodontist who installed my implants.
The patient now requires implants in left posterior maxilla, where the bone height is less than 5mm, bone classification is D3.
I have a case with early crestal bone loss. Can I use PRF?
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?
