Background: Polycaprolactone (PCL) is a synthetic aliphatic polyester widely used in biomedical applications with biodegradability in the body and promotes cell proliferation and differentiation. A newly developed bilayered PCL membrane was developed for possibly being used as a membrane in guided bone regeneration (GBR).Purpose: To compare the clinical efficacy between a newly developed bilayered PCL membrane with a Cytoplast™ RTM collagen membrane for GBR with simultaneous implant placement.Materials and Methods: Twenty-four patients were randomized to PCL or RTM group, and a total of 24 dental implants were placed. Primary outcomes were patient mean buccal bone thickness (BBT) immediately postimplantation and at 6 months using cone-beam CT and soft tissue surface dimensional changes (STC) at crown insertion, 6 months, and 1 year after loading using intraoral scanner. Secondary outcomes included success rate, clinical parameters, healing index, implant stability, pink esthetic score, and marginal bone levels.Results: The percentage of reduced BBT at 6 months was 32.38%, 25.94%, and 23.96% in the test group and 34.42%, 14.75%, and 6.34% in the control group at the corresponding levels. The mean difference of changed BBT associated with PCL membrane, when compared to collagen membrane, at 6 months was À0.02 ± 0.18 mm (95% confidence interval [CI]: À0.40 to 0.35), 0.29 ± 0.28 mm (95% CI: À0.29 to 0.87), and 0.62 ± 0.38 mm (95% CI: À0.17 to 1.42) at 0, 2, and 4 mm from implant shoulder. Minimal loss of STC was observed in both groups up to 1 year of loading. The mean difference loss of surface dimensional change associated with PCL membrane, when compared to collagen membrane, at 1 year of loading was 0.31 ± 0.19 mm (95% CI: À0.07 to 0.70), 0.22 ± 0.26 mm (95% CI: À0.33 to 0.76), and 0.17 ± 0.30 mm (95% CI: À0.45 to 0.78) at 0, 2, and 4 mm from implant shoulder. None of these differences were statistically significant (unpaired t-test, degrees of freedom [df] = 22; p > 0.05). Conclusion:Within the limits of this trial, both barrier membranes resulted in comparable outcomes for GBR with implant placement after 1 year in function. Further research is necessary with a larger sample size.

“…Currently, the immediate implant placement in the aesthetic zone has been widely implemented because of the excellent shortterm treatment outcomes (Slagter et al, 2014), the small influence on the aesthetic long-term outcomes (Arora & Ivanovski, 2018), the good facial-lingual implant location, and the stability provided to the facial alveolar bone wall (Miyamoto & Obama, 2011). It is worth noting that several studies concluded that immediate implant placement in the anterior maxilla was associated with a high risk of aesthetic complications, mainly in the form of facial vertical bone resorption and, consequently, the recession of facial mucosa (Chen & Buser, 2014;Cosyn et al, 2016;Roccuzzo, Gaudioso, Bunino, & Dalmasso, 2014).…”

Objectives:The purpose of this cone beam computed tomography (CBCT) study was to describe facial alveolar bone alterations and gray value (GV) changes around implants in aesthetic anterior maxilla with simultaneous guided bone regeneration (GBR) and to investigate potential influence of factors related to vertical alveolar bone stability, such as particle sizes of the deproteinized bovine bone mineral (DBBM) used. Materials and Methods:A retrospective study design was adopted. Four facio-palatal cross-sectional CBCT images of 166 implants from 124 patients who had maxillary anterior implants were obtained. Measurements of the vertical facial alveolar bone level (VFBL), horizontal facial alveolar bone thickness (HFBT), and GV were identified of 1-3 years. Then, correlation coefficients for those parameters were calculated. Finally, linear mixed models were established to investigate potential factors influencing vertical alveolar bone resorption.Results: Facial alveolar bone underwent fast bone modeling and remodeling during the first 6 months, with decreases of 1.00 ± 1.19 and 0.74 ± 0.86 mm in VFBL and HFBT in implant shoulder, respectively, and there was positive and significant correlation between the alterations in VFBL and HFBT1 (r s = .516, p = .000). Linear mixed models identified particle size of DBBM as a critical factor associated with vertical bone resorption (p = .000). The GV gradually increased during the follow-up period. Conclusions:Rapid and unavoidable peri-implant bone resorption usually happened during the first 6 months after implant placement. GBR is a predictable treatment for maxillary anterior implants, since GV has an increasing trend. Large bone particles of DBBM help maintain vertical alveolar bone stability.

“…Currently no systematic review reports complication rates for PES/WES/ICAI, however our results are also comparable to other clinical prospective and retrospective studies that report PES/WES in the literature. When looking at unfavorable PES results, reports range from 0–19% [ 61 , 62 , 63 , 64 ], for WES: 0–21% [ 61 , 62 , 63 , 64 ], and PES/WES combined: 0–24% of cases [ 64 , 65 , 66 , 67 ]. Overall, both the results from our study and those in the literature revealed that unfavorable aesthetic outcomes as measured by PES/WES/ICAI, has a large range from 0–24%.…”

Success Rates and Complications Associated with Single Immediate Implants: A Systematic Review

et al. 2022

This study examined the success rates of single immediate implants and their associated biological, hardware and aesthetic complications. Using a developed search strategy, randomized controlled trials (RCTs) on single-unit immediate implants with at least six human participants, a minimum follow-up time of 12 months and published between January 1999 and January 2021 were identified. Data was extracted independently using pre-designed data extraction forms. Information on success rates and associated biological, hardware and aesthetic complications were obtained and assessed. Out of 191 potentially eligible studies, 26 RCTs assessing 1270 patients with a total of 1326 single implants were included and further evaluated. In this review, success rate was reported to be 96.7–100% over a total of 9 studies. However, there was a lack of consensus on a universal success criterion between authors emphasizing the need for agreement. The average follow up was 29 months and most reported complications were aesthetic (63 cases, 4.7%), whilst there were relatively fewer biological, (20 cases, 1.5%), and hardware complications (24 cases, 1.8%). Success rate is an uncommon clinical outcome with 9 out of 26 of the selected RCTs reporting it. In these studies, single immediate implants showed a high success rate with low numbers of biological and hardware complications, and high patient satisfaction with aesthetics were reported in the short-term follow-up of one year.
