External Resorption Using 2.75 mm Implants

Dr. Paul Mozer

Present Situation

The patient presented with the diagnosis of external resorption in the lower anterior mandible. Due to the very thin ridge of bone treatment planning options included onlay block grafting with the disadvantages of a second surgical site, co-morbidities, and technique sensitive surgical procedures.

The traditional prosthetic dental options of lower partial denture and fixed bridge were alternatives that were less than desirable for the patient.

Clinical Solution

Patient opted for 3 CloseFit Ultra Narrow Implants (2.75 mm diameter) in the lower arch for a less invasive and immediate placement solution.

CloseFit Ultra Narrow Implants were treatment planned for guided surgery with 360Imaging. Surgical guides were fabricated and the affected teeth were extracted as atraumatically as possible. Particulate bone grafts were placed with aPRF and iPRF and 3 Adin Closefit Ultra Narrow 2.75 mm implants were immediately placed with cover screws.

After 4 months of healing, the site was uncovered, healing abutments placed for tissue contouring and an open tray impression taken with Impregum. Three splinted screw retained crowns were secured in place and the lingual screw accesses were covered with PTFE tape and resin.

What’s the difference in implant planning and surgical placement between a wide ridge and an ultra-thin ridge? Nothing! With Adin guided surgery and 360Imaging surgical guides, the Ultra Narrow Platform 2.75 mm conical connection implant is just as predictable to place in an ultra-narrow ridge as a 5.0mm implant in a wide ridge.

Without the predictability and ease of guided surgery, treatment planning for a narrow ridge would include the options of onlay block grafting and delayed implant placement, partial denture or fixed bridge.

With the 2.75 mm implant, this case can be accomplished by straightforward immediate implant placement for improved patient satisfaction.
