Alveoloplasty for full arch rehabilitations?

ridge width

I 2-17mm to allow space for prosthetic components; MUA, bar, etc, if doing a hybrid

The purpose of the alveoloplasty is not solely to hide the transition between the prosthesis and the gingiva. The amount of alveoloplasty also depends on the final prosthesis you want to fabricate. You don't have to do any alveoloplasty at all if you can work with the natural gingiva (when doing immediate implants after exo for example) and the final prosthesis is a Cr-Co+ceramics. Not an easy job for sure compared to traditional acrylic ALL-ON.4. I wouldn't do that in a zirconium frame though because the material volume could not be enough (27 rule - 3X3X3 - and even this rule is debatable) to minimize fracture. For a hybrid (acrylic) less then 15mm would not be ideal so you need to measure the amount of alveoplasty needed based on the final prosthesis that the patient and you want.

Alveoloplasty may be needed to : 1) create sufficient prosthetic space, 2) create sufficient ridge width for surgical implant placement, 3) hide gingival/prosthetic transition line, 4) level out alveolar ridge for if placing adjacent dental implants.

Alveoplasty for full arch cases is very involved and should only be done by experienced surgeons or surgeons being mentored by one. Have a look at these Chrome guide webinars which give better understanding of their system not that I am advocating using it, it is good but expensive. https://www.youtube.com/watch?v=fnvlkFiEIHY https://www.youtube.com/watch?v=5m2eernHNlE https://www.youtube.com/watch?v=jLj3A7LdmJs https://www.youtube.com/watch?v=L-BLOxgQkLU there are others but gives you an idea of the variables you need to look at when doing such surgeries.

Great summary, John Kong. It refreshes our ideas!

Thank you

are we talking about alveolectomy or alveoloplasty?
