“…On the contrary, some reports indicated that subcrestal implants showed no superiority against equicrestal implants with regard to the preservation of peri‐implant crestal bone levels . The findings of the present clinical trial are in line with the study conducted by Amri et al in which no statistically significant differences were found between crestal and subcrestal implants for the mean MBL changes at 6, 18, and 36 months. A recent systematic review and meta‐analysis reported that for bone level implants, the weighted mean of crestal bone loss before and after abutment connection was 0.03 ± 0.30 mm and 0.66 ± 0.11 mm when IAI placed subcrestally and 0.57 ± 0.29 mm and 0.80 ± 0.30 mm when IAI placed equicrestally .…”

Background Placement of the implant‐abutment interface (IAI) away from the bone crest has been suggested to have positive impacts on maintenance of peri‐implant tissues. Purpose To assess the effects of platform‐switched and platform‐matched implants, taking into consideration the IAI at different positions relative to the bone crest, on clinical, radiographic, and microbiological outcomes during 12 months following functional loading. Materials and Methods The present prospective randomized study was performed upon 70 patients. Group I (n = 23) implants presenting a platform‐switched implant‐abutment connection design was inserted 1 mm subcrestally. Group II (n = 22) implants with similar properties were inserted crestally. Group III (n = 25) implants presenting a platform‐matched approach with an internal hexagon connection design was inserted crestally. The periodontal parameters were assessed at baseline, and 3, 6, and 12 months postloading. Radiographic marginal bone level (MBL) changes were analyzed at the 12‐month follow‐up. The amount of DNA copies of Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, Tannerella forsythia, Provetalla intermedia and total bacterial mean load in peri‐implant sulcus fluid (PISF) were assessed at the same periods. Results There were no significant differences among the groups with respect to the periodontal parameters for all time periods. At 12‐month follow‐up, the MBL changes were 0.16 ± 0.29 mm and 0.17 ± 0.23 mm for group I, 0.15 ± 0.25 mm and 0.17 ± 0.26 mm for group II, 0.17 ± 0.26 mm and for group III in mesial and distal sites, respectively. The mean total bacterial load was found significantly higher for group III compared to the other groups in the three interval times (P < .05). Conclusion Implants restored with platform‐switching and platform‐matching performed equally regarding clinical and radiographic outcomes. Platform‐matched implants inserted at the crestal level presented higher the mean bacterial total load in PISF.

Meanwhile, the mesial and distal radiographic bone‐to‐implant contact in test group −0.32 mm was greater than the earlier studies on this technique, similar to the radiographic bone‐to‐implant contact −0.30 mm than the implant placed 2 mm subcrestally and also lesser than the bone‐to‐implant contact of −0.74 mm published earlier by Huang …”

Background Early implant placement combined with simultaneous contour augmentation was able to rebuild stable facial hard‐tissue and soft‐tissue contours that were esthetically pleasing. The purpose of this study was to evaluate the clinical esthetic outcome, when two different bone grafting materials were used. Methods Forty‐eight patients were randomly assigned into two groups. In the control group, autogenous bone was used to cover the exposed implant surface then a layer of deproteinized bovine bone mineral (DBBM) was added. This graft combination was then combined with a collagen membrane. In the test group, the exposed implant surface was covered with a layer of freeze‐dried bone allograft (FDBA) in combination with the collagen membrane. Modified plaque index (mPI), modified sulcular bleeding index (mSBI), probing depth (PD), keratinized mucosa (KM), implant crown length (IC), distance from the implant shoulder radiographic bone‐to‐implant contact (DIB), pink esthetic score (PES), and white esthetic score (WES) were measured at 12‐months post implant loading. Results All 48 implants were clinically successful, and no significant differences were observed in mPI, mSBI, PD, KM, IC, DIB, PES, and WES at 1‐year implant loading. The mean mucosal recessions of test and control group were unchanged, 0 and –0.02 mm, respectively. The mean DIB were –0.32 and –0.21 mm in test and control implants, respectively. The mean totals of PES/WES were 15.29 and 15.33 for the test and control groups, respectively, with no significant difference between groups. Conclusion This study demonstrated that autogenous bone plus DBBM and FDBA each combined with a collagen membrane both resulted in stable clinical and esthetic outcomes in early implant placement with contour augmentation after 1 year.

“…Peri‐implant probing depth (PPD) was measured as described elsewhere; and digital bitewing radiographs (Ektaspeed plus; Kodak, Rochester, New York) were taken and viewed on a calibrated computer screen (Samsung SyncMaster digital TV monitor, Suwon City, Gyeonggi‐do, Korea). CBL was measured as the linear distance from 2 mm below the implant‐abutment interface to the most crestal part of the alveolar bone . Peri‐implantitis was defined as the presence of at least 1 peri‐implant site with a PPD of ≥ 4 mm; and radiographic mesial or distal CBL of ≥3 mm around the implant .…”

Soft tissue changes and crestal bone loss around platform‐switched implants placed at crestal and subcrestal levels: 36‐month results from a prospective split‐mouth clinical trial

Abstract: Up to 36 months of follow-up, soft tissue parameters and crestal bone levels can remain equally stable around dental implants placed at crestal and subcrestal levels. The need for long-term follow-up clinical trials is also emphasized.
