Guided Bone Regeneration with Concentrated Growth Factor Enriched Bone Graft Matrix (Sticky Bone) vs. Bone-Shell Technique in Horizontal Ridge Augmentation: A Retrospective Study

Abstract

Background: The purpose of this study was to compare clinical results of two different horizontal ridge augmentation techniques: guided bone regeneration with sticky bone (SB) and the bone-shell technique (BS). Methods: Records of patients who underwent horizontal ridge augmentation with SB (test) and BS (control) were screened for inclusion. Pre-operative and 6-month post-operative ridge widths were measured on cone beam computer tomography (CBCT) and compared. Post-operative complications and implant survival rate were recorded. Results: Eighty consecutive patients were included in the present study. Post-operative complications (flap dehiscence, and graft infection) occurred in ten patients, who dropped out from the study (12.5% complication rate). Stepwise multivariate logistic regression analysis showed a significant inverse correlation between the occurrence of post-operative complications and ridge width (p = 0.025). Seventy patients (35 test; 35 control) with a total of 127 implants were included in the final analysis. Mean ridge width gain was 3.7 ± 1.2 mm in the test and 3.7 ± 1.1 mm in the control group, with no significant difference between the two groups. No implant failure was recorded, with a mean follow-up of 42.7 ± 16.0 months after functional loading. Conclusions: SB and BS showed comparable clinical outcomes in horizontal ridge augmentation, resulting in sufficient crestal width increase to allow implant placement in an adequate bone envelope.

Influence of buccal and palatal bone thickness on post-surgical marginal bone changes around implants placed in posterior maxilla: a multi-centre prospective study

“…However, edentulous ridge width at implant placement site plays a crucial role: an adequate peri-implant bone envelope has a protective effect against the detrimental influence of the aforementioned factors on peri-implant marginal bone stability. In case of insufficient bone width, the clinician may perform horizontal ridge augmentation procedures [ 20 , 21 ], use implants with reduced diameter [ 22 , 23 ] or plan a combination of the above. Nevertheless, there is no agreement in the literature on the minimum amount of bone that should surround an implant.…”

Radiographic Evaluation of bone density after bone grafting associated with different laser bio-modulation techniques in rat

“…The results of graft bone density and implant stability after bone grafting with sticky bone were promising. Although the published data are case reports and case series (14,15) the results has shown to be clinically significant compared to xenograft alone.…”

“…However, the study didn't clarify the exact results and the statistical difference at the 3 months follow up time. 15 compared the bone graft with bone shell versus sticky bone around dental implant in 127 implants. The results have shown that the amount of bone formed was comparable in both groups with no statistically significant difference in bone density.…”

Measuring the outcomes of lateral ridge augmentation using cone‐beam computed tomography

“…Assessing the success of bone augmentation using CBCT has been reported in the literature by others over the past few years. Bone width has been assessed using CBCT for treatments performed with bone blocks, 14,15 and using autogenous bone 16,17 or autogenous tooth roots 18 . Basma and colleagues showed that larger bone particles used during augmentation surgery resulted in a larger increase in bone thickness at the surgical site 19 .…”
