Full-arch Re-treatment cases are often complex because they require a thorough evaluation of both the remaining bone proposition and potential restorative efficiency of the previously placed implants.
In cases where it is possible to preserve an integrated implant without compromising the prosthetic prognosis we will towards a partial ex-plantation and will connect 1 or 2 functional implants into the future full-arch, which is nowadays made easy by utilising digital technology and re-creating the implant position in the project.
In this clinical case, for example, the patient was referred with implants having being placed 6 months prior and after evaluation we decided to re-do the full-arch completely from scratch due to the implants being partially exposed already in the gingival and bone as well as not having optimal restorative positions.
Due to severe sinus pneumatization and bone loss after implant removal we opted for a hybrid-zygomatic (zone 2) configuration with a combination of two pterygoids in the posterior (zone 3) as well as a M-point and Vomer implant in the anterior region (zone 1) for optimal AP-spread. Final restoration delivered in 4 months.
