“…A Significant bone loss of an average of 0.66 mm was found in all groups between implant placement and crown installation and an average bone loss of 0.54 mm between implant placement and one-year time point. No significant bone level changes were proved between the first year and ten years follow-up [16]. This data is comparable with the results of our study which shows a mean bone loss of 0.69 mm.…”

“…Therefore, it is important to take the soft tissue vertical dimension in to account at the moment of implant placement when conducting a study that measures the crestal bone changes. Gilbert et al [16], demonstrates a marginal bone level change of 0.35 mm around the moderately rough implants vs hybrid implants after a one-year follow-up in a split-mouth study. It is important to note that in this prospective study, the implants were placed with respect to the future biological width establishment.…”

Aim: The aim of this study is to investigate the crestal bone loss around the implants following guided bone regeneration in dehiscence and fenestrations and its effect on peri-implant health after a period of five years. Materials and Methods: A total of 41 consecutively treated patients who had received bovine particulate bone augmentation Endobon® (Biomet 3i) were evaluated in a single center. From this cohort, 13 patients were enrolled in the study and the others were drop-outs. 17 implants were installed in the patients. The patients were contacted 5 years after implant loading. All patients had undergone periapical radiographs and orthopantogram immediately after crown installation T0 and then 5 years after placing the implants T1. Digital and analog radiographs were evaluated by one clinician from the patient charts after the crown installation. The periodontal chart was taken, pocket depth, bleeding on probing and plaque amount was scrutinized around each implant. Statistical analysis was performed using SPSS software Results: All implants survived after 5 years of loading. Significant bone loss was revealed between the baseline and the follow-up time at the implant sites. The overall mean bone loss at the implant site was 0.69 (SD: 0.73). On the mesial side for all but two implants (0.03 and 0.04) the evolution was toward bone loss. On the distal side for all but three implants (0.01, 0.02, 0.02) the evolution was toward loss of bone. No difference in the bone loss was seen between mesial and distal sites. 87.5% of the implant sites with bone augmentation showed bleeding on probing. The plaque was seen in 31.3% of the implant sites Conclusion: Bone augmentation with bovine bone hydroxyapatite in one stage implant surgery remained stable during the 5 years follow-up around the minimally rough implants used in this study. However, the amount of bone loss and mucositis at the implant sites with GBR remained significantly high.

“…Such a feature has been confirmed in several animal and clinical studies [10][11][12][13][14]; on the other hand, the negative effect of surface roughness on plaque formation should be taken into account [22][23][24]. In an implant with hybrid surface, the moderate roughness of the body increases the osseointegration while the minimum roughness of the crest minimizes peri-implantitis [18]. In a 5-year clinical trial, two groups of implants with different surface roughness were compared; wherein, implants with minimum roughness had more desirable clinical symptoms and had significantly better performance in preserving the marginal bone [17].…”

“…A 5-year clinical study reported a mean bone loss of 0.5 mm for implants with moderate surface roughness and 0.2 mm for implants with minimum surface roughness [26]. In a study conducted by Glibert et al [18] aimed at evaluating implants with hybrid surface and moderate roughness in toothless patients, the follow-up radiographs were taken 3 and 12 months after placing the prosthesis, and bone loss was studied in two groups. As a result, implants with hybrid surface showed better performance, implying that hybrid implants were more suitable for implant-based treatments [18].…”

“…In addition, a 5-year clinical study compared 42 implants with average roughness with 42 implants with minimum roughness and indicated that soft tissue inflammation around implants with radiographic bone loss >2.5 mm was significantly more than that around implants with average roughness [17]. By using hybrid implants with minimum surface roughness in the crest module and average roughness in the body, we can benefit from the advantage of minimum surface roughness without endangering osseointegration [18]. Considering the existing controversy regarding the effect of surface roughness on marginal bone conservation, additional studies are warranted in this area.…”

Background and Aim: This retrospective study aimed to investigate the effects of surface roughness and implant body design on the amount of crestal bone loss around implant. Materials and Methods: In this retrospective study, dental records of 87 patients who received 139 implants were evaluated. The ITI group received 63 implants with moderate roughness, while the DIO group received 76 implants with hybrid roughness. Radiographs were taken immediately after implant placement, on the day of loading of the prosthesis, and 1 and 2 years after loading by using the parallel method. The Mann-Whitney U test was used to compare bone loss in the two groups at different time points, and the Wilcoxon test was used to evaluate the intra-group variations during a period of 1-2 years after applying the force (P=0.05). Results: Radiographic records of 23 implants (16%) were unavailable during the second year. The ITI group had more bone loss at all three time points. Marginal bone loss in the ITI group during the second year was 0.65±0.44 mm and was significantly more than that in the DIO group (0.28±0.16 mm; P<0.05). The mean bone loss during the time interval of the first to the second year was significantly less than the bone loss during the time interval of loading to the first year (P<0.05) in both groups. Conclusion: Based on the failure criteria, none of the implants failed after 2 years of loading. Implants with hybrid surface roughness were superior in preserving the marginal bone around implants against occlusal forces.
