All-on-4 concept using TiUltra surface implants and Multi-unit Xeal abutments: Report on the outcomes between 6 to 36 months
The All-on-4 treatment concept represents a protocol for the immediate function of full-arch fixed prosthetic rehabilitation with good long-term outcomes [1,2,3]. Novel anodized surfaces have been developed for both dental implants and abutments aiming to enhance both hard and soft tissue outcomes (osseointegration and mucointegration, respectively) in immediate function rehabilitation protocols4. This study investigated the clinical outcomes of such surface innovations in the context of full-arch established protocols.
The aim of this study was to evaluate the outcome of full-arch rehabilitations through the All-on-4 concept using implants and abutments with an ultra-hydrophilic, multi-zone anodized surface with a follow-up between 6 months and 3 years.
- 100% cumulative implant and final prosthesis survival rates.
- Minor mechanical complications in 9 patients (21%) including: provisional prosthesis fracture (n = 9 patients) subsequent to abutment loosening in (n=3). All provisional prostheses fractures were resolved by mending in the laboratory, re-tightening of the abutment, or occlusion adjustment.
- No biological complications. One patient developed a probing pocket depth of 5 mm (pseudo-pocket).
- Healthy soft tissue, with the modified plaque and bleeding indices scored as 1 for all patients at last follow-up.
- Excellent marginal bone response, with a mean marginal bone loss of 0.39 mm from insertion to 1-year follow-up (n = 35 patients).
