A restorative practice is often kept busy by chronic denture wearers who complain of denture movement during function. For patients with extremely narrow ridges, the resorption of edentulous ridges underneath dentures is challenging for denture retention. Thankfully, the Straumann RidgeFit implants system was developed for these specific situations.
RidgeFit implants consists of a one-piece, tissue-level implant with an Optiloc prosthetic connection available in an endosteal diameter of ∅2.4 mm, with varying lengths of 10 mm, 12 mm, and 14 mm.
RidgeFit Implants: A Visual Essay
The visual essay below is of an 85-year-old woman who has been a regular patient in our office for years. She lost her teeth when she was young and has worn complete dentures for over 40 years and recently inquired about the possibility of improving the retention of her dentures.
Upon CBCT evaluation, it was verified that placement of conventional implants would be challenging due to the resorptive pattern of her ridges; however, her case was suitable for the RidgeFit implants system.
To provide an adequate reference for implant placement, we utilized her pre-existing dentures, duplicating them as a surgical template. Once the implants were placed and three months were allotted for osseointegration, the implants were actively loaded. The patient was satisfied with the overall esthetics of her dentures, so it was decided to utilize her pre-existing dentures further and pick up the prosthetic connection of the implants, mitigating the cost of a new denture. In the end, the patient was delighted with the results.
Below are images of the procedure's steps illustrating how to convert existing dentures to implant overdentures for a chronic denture wearer with narrow ridges utilizing RidgeFit implants. It represents a simple alternative technique that may substantially improve a patient's quality of life.
