Plaque Accumulation Beneath Maxillary All‐on‐4™ Implant‐Supported Prostheses

Abstract

These findings suggest that the hygiene of the All-on-4 prostheses could be improved by maximizing the distances between the inserted implants in the jaw, minimizing the prostheses' palatal extension and guiding patients to optimize their oral hygiene practices targeting the palatal area of their prostheses.

Ten years follow‐up retrospective study on implant survival rates and prevalence of peri‐implantitis in implant‐supported full‐arch rehabilitations

“…In our investigation, we did not find a statistical correlation between smoking and implant loss/peri‐implantitis; we can hypothesize that the difficulties in evaluating retrospectively the number of cigarettes realistically smoked by the patients during the entire period of the investigation could have limited the possibility to explore such link. Moreover, in the present study, no data about the cleanability of the prosthesis (that was related also to the characteristics of the prosthesis itself; Abi Nader et al, ) were presented even though insufficient oral hygiene should be considered a risk factor for peri‐implantitis (Schwarz et al, ). Finally, other factors related to surgical procedure (immediate implants, grafting procedures, bone stiffness) were not statistically evaluated in relation to the outcomes.…”

Maxillary Overdenture Retained with an Implant Support CAD-CAM Bar: A 4 Years Follow Up Case

“…The use of a bar-sustained overdenture compared to a fixed rehabilitation gives some advantages: a predictable management of the aesthetics; easier home hygiene [18-20]; the total implant support reduces the resorption of the bone crest; avoidance of the resin palate from the prosthetic design granting a higher comfort. In our patient we used a CAD-CAM titanium bar [12] that give us many advantages: tension-less fit; system usable with all implant interfaces; positioning of the structure on implant level (which can be screwed directly to the internal connections of implants) or on abutment; use of only one metal (pure titanium grade 2) [21]; less time consumption and laboratory work; micrometric precision: the producer guarantees discrepancies below 20 μm on the vertical axis, and below 30 μm on the horizontal axis.…”

Four-implant overdenture fully supported by a CAD-CAM titanium bar: A single-cohort prospective 1-year preliminary study

“…In patients with moderate to severe bone resorption, the delivery of an FDP can be contraindicated because of the excessive vertical and horizontal overlap of the prosthetic flange onto the residual ridge, which can make hygienic maintenance challenging for the patient. 13 The placement of at least 4 implants of standard length may allow the delivery of an overdenture supported by a CAD/CAM titanium bar, 14 avoiding any bearing area on the soft tissue and reducing the denture base extension. 32 In the present study, the 1-year implant and prosthetic success and survival rates were 100% in both the mandible and the maxilla, and greater patient satisfaction was reported, indicating that the 4IO is a reliable treatment option.…”
