Both. Both grafts are highly successful. There really is not a "better" one. I do these grafts all week long, and they are appropriate for different tissue types and areas, as well as different patients. Depending on the size, and location of the recipient site, one may be indicated where the other is not. Consult your periodontist and they can advise you which is better for a particular situation!
Palate. Both alloderm and palate tissue work predictably for gum grafts. However, since the palatal tissue is from your own body and is vascular to begin with, it tends to work 'better' in my hands.
Palatal tissue. In my opinion palatal tissue is always a better choice.. My success is almost 100% with palatal tissue vs a much more unpredictable result with alloderm.
Alloderm, probably. Alloderm works just as well as natural tissue grafting in many instances, and it requires less injury to your gums for placement. There are some cases where it may not be the better solution, but those are few. If your dentist/periodontist feels alloderm will work, it is the option i would choose.
Alloderm. Palatal tissue is limited, and patient will suffer from the discomfort of donor site. Alloderm is a good alternative allowed for larger graft, less morbidity (eliminate the donor site), andhas a comparable sucess rate.
Depends on Size. Both grafting techniques have advantages. If you need a graft just on one tooth, the palatal wound of the donor site isn't too bad. In fact, most patients will come report that the roof of the mouth was not a big deal. If you need 3 or more teeth in a row grafted, you may want to consider the alloderm. Read more...
One healing site. With alloderm, you don't need to have tissue removed from the roof of your mouth, so you only have one surgical site that needs to heal as opposed to two sites. Read more...
