Maintenance of Peri-implant Tissues
As described in the literature, the One-Abutment-One-Time technique involves placing a definitive abutment at the same time as implant insertion, avoiding subsequent disconnections that can compromise the biological seal. This clinical approach allows for better preservation of peri-implant tissues, reduced marginal bone loss, and more stable and predictable healing.
Clinical basis of the transepithelial abutment
The classic concept based on the 4.8 mm diameter Avinent trans-epithelial abutments has demonstrated reliable and stable long-term clinical results, as extensively described in the literature. It is on this established foundation that the new Avinent SLIM abutment has been developed, with an optimized design to meet current clinical needs, particularly regarding the treatment of peri-implant tissues.
Evolution of the New SLIM Design
This evolution of the profile and geometry allows for increased soft tissue space, promoting greater biological stability and improved bone retention. It also facilitates surgical and prosthetic protocols, making them more predictable, particularly in the placement of subcrestal implants. This is not intended to replace the classic concept, but rather to complement it according to the specific clinical indication.

Figure 2. Replacing a classic transepithelial abutment with a Slim abutment allows for soft tissue accumulation in both the buccal and palatal areas, reducing pressure on the mucosa and relieving tension on the alveolar crest, thus promoting greater preservation of peri-implant tissues.
