Purpose: To determine the effect of 0.7- and 2.4-mm transmucosal abutment height titanium bases on the crestal bone stability and peri-implant soft tissue condition of bone-level implants with platform switching in patients with vertically thick soft tissues. Materials and methods: Sixty bone-level platform-switched implants were placed in the m...

The cover image is based on the Original Article Influence of new immediate tissue level abutment on crestal bone stability of subcrestally placed implants. A 1‐year randomised controlled clinical trial by Tomas Linkevicius et al., https://doi.org/10.1111/cid.12979. The cover image is based on the Original Article Influence of new immediate tissue...
Article
Purpose: To evaluate the efficacy of cleaning protocol in decontamination of organic compounds from polished zirconium oxide samples. Materials and methods: A total of 24 rectangular plate specimens were sintered from zirconium oxide. All samples were polished with commercially available polishers (course, fine, and superfine) and polishing past...
Article
Background: The relation between implant abutment disconnection (AD) and increased crestal bone loss is still debated. Purpose: To compare bone changes below implant-abutment junction of subcrestally placed implants between: (1) implant level restorations, that underwent four ADs and (2) implants with immediate tissue level abutment with no AD,...
Article
Objective To evaluate the amount of residual cement after cementation of implant crown‐abutments with rubber dam and retraction cord with copy abutments techniques. Material and Methods Thirty single posterior metal‐ceramic implant‐supported restorations were delivered to 20 patients. The crowns were fabricated with occlusal openings obturated wit...
Article
Purpose Aims of the study were: (a) to register crestal bone loss around 1.5 mm subcrestally placed implants and epicrestally placed implants with soft tissue tenting technique, (b) to record bone remodeling in subcrestal group, and (c) to determine the increase of vertical soft tissues after tenting. Materials and methods Thirty‐two patients with...
Article
Purpose: To evaluate the surface roughness values of zirconium oxide samples that were gradually polished using a commercially available polishing system and polishing paste. Materials and methods: A total of 50 rectangular specimens of predetermined size (10 × 10 × 3 mm) were sintered from zirconium oxide. Samples were randomly assigned to one...

Objective To evaluate how vertical mucosal tissue thickness affects crestal bone stability around triangular‐shaped bone‐level implants, restored with low profile titanium bases and monolithic lithium disilicate restorations. Material and methods Fifty‐five bone‐level implants of 4.3 mm diameter were evaluated in 55 patients (22 males and 34 femal...

... Assuming that the alveolar bone is the basis for the dental implants function according to their purpose in the act of biting and mastication [11,12], other factors such as soft tissue condition, depth of gingival pockets, gingival biotype, width of the keratinized gingival zone, color and translucency of soft tissues [13][14][15] are, however, secondary. In recent years, increasing attention has been paid to the phenomenon of corticalization [16][17][18]. It had been hypothesized that after bone remodeling of bone above the implant neck, almost ...
... In contrast, five-year observations indicated that corticalizing effects and bone loss are lowest with subcrestal implants. This is in full accordance with the observations of the Vilnius Research Group [18,19]. ...
... 2,5,6 In this sense, criteria utilized to measure successful outcomes include pros-thetic success, 7,8 and quantitative and qualitative measures describing peri-implant soft and hard tissues health, [9][10][11][12] contour and position. [13][14][15][16][17][18][19] These outcomes have been shown to be affected by a variety of local [20][21][22][23][24][25][26] and systemic [27][28][29][30][31][32] factors. ...
... Furthermore, CAD/CAM facilitated fabrication of monolithic hybrid abutment crowns in a complete digital workflow appears to be a time and cost-efficient treatment option for posterior implants. 51,52 With respect to the surrounding peri-implant soft tissues, zirconia materials seem to be in favor compared to LDS. [53][54][55] However, post-processing in terms of polishing or glazing of LDS might affect its biocompatibility. 53,56 Therefore, a combination of a subgingival zirconia material and a supragingival LDS restoration for screw-retained hybrid abutment crowns should be further elucidated. ...
... Thus, by creating space underneath the covering mucosal flap, soft tissue thickness was improved and bone loss could be reduced. 10 This is consistent with a previous report by Salama et al, 7 who termed this concept "guided soft tissue augmentation." ...
... Recently, an implant with a triangular neck configuration became available on the market [27][28][29]. Several clinical studies have demonstrated that this triangle neck design can achieve primary stability, proper osseointegration, stability of the peri-implant tissues and patient satisfaction [28][29][30]. Li Manni et al. [29] conducted a randomized controlled trial to compare the peri-implant bone changes at a circular and triangular shaped neck implant designs. After 1 year of loading, the proximal bone loss was 0.22 ± 0.30 mm for the triangular neck and 0.42 ± 0.67 mm for the circular ones (p = 0.25). ...
