This case highlights the evolving variations in dentoalveolar augmentation with an emphasis on concomitant implant placement. In the most traditional sense, a vertical osteoperiosteal flap technique would be bound with a stable basal bone that can be used to anchor simultaneous dental implant placement.

A critical appraisal of the gingival architecture in the final end point of this case demonstrates some radiolucency through the soft tissue outlining the platform of the Nobel Biocare TiUnite implant. This would lead us to believe that either the transmucosal bone level placement attempt was inaccurate or excessive reflection of the labial tissue has caused some degree of resorption. This is anot...
A suitable alternative surgical management of this particular case might have been to simply perform an alveoloplasty to produce the desired inter-occlusal clearance and proceed with placement of implant and simultaneous direct sinus lift. That would have left more of the apical portion of the implant within the grafted sinus and possibly modified the location of keratinized band of tissue. The lo...

Obtaining proper occlusal clearance to allow for a single unit crown restoration is a fundamental prerequisite for dental implant restoration. Long-standing edentulous sites are often fraught with disuse atrophy and unopposed supra-eruption of the opposing dentition. In the posterior maxillae/mandible, there are vital structures that have to be mobilized in order to allow space for either bone tra...
Dental restorative space from the opposing dentition requires adequate distance for restorative material for an acceptable restoration. Typically, long-standing edentulous alveolar ridges will have vertical and or horizontal defects that require alveolar ridge augmentation for ideal dental implant restorations. Along with these defects, one will see the opposing dentition supra erupt which can obl...

Within the limitations of this clinical study, we may conclude that the use of CCXBB in combination with DBBM particles and a native bilayer collagen membrane for staged lateral bone augmentation in severe atrophic alveolar crests achieved significant horizontal crestal width allowing for staged implant placement in most of the patients. Histological analysis and implant survival records indicate ...
The immune-histochemical results reported expression of osteopontin mainly at the border between mineralized vital bone (MVB) with CCXBB, what coincides with findings from previous reports [38,39,40]. Alkaline phosphatase (ALP) is considered as an early osteoblast differentiation marker [41]. ALP-positive cells were detectable, in all specimens on the periphery of MVB, associated to areas of new b...
When correlating the clinical results and the histological outcomes, there was a positive association between the presence of soft tissue dehiscence with CCXBB exposure and a diminished amount of new mineralized bone (p = 0.06). This lower amount of new bone within the xenogeneic graft suggests a lack of full graft integration and diminished vascular supply, what may have caused the soft tissu...
The purpose of this investigation was to evaluate histologically and immunohistochemically the behavior of CCXBB blocks when used for staged lateral bone augmentation in severe human horizontal residual bone defects. Six months after the regenerative intervention using the CCXBB blocks, the mean increase in bone width was 4.12Â mm and hence, this outcome allowed for the placement of dental implant...
The results from the histomorphometric measurements are depicted in Table 2. Bone biopsies were composed by 21.37% (SD 7.36) of residual CCXBB, 26.90% (SD 12.21) of mineralized vital bone (MVB), 47.13% (SD 19.15) of non-mineralized tissue and 0.92% of DBBM (Fig. 5b). Biopsies from patients who lost their implants had a statistical significant lower amount of MVB (p = 0.01u) and a statistical...
Twenty-eight CCXBB blocks were placed in 15 patients that fulfilled the selection criteria (12 women and 3 men) with a mean age of 54.5 (SD 8.34).
The detailed clinical and radiographical outcomes have been reported previously [21]. In brief, one patient experienced pain and soft tissue dehiscence leading to removal of the graft material 3Â days after the regenerative procedure. Another patient r...
For the immunohistochemical analysis, the semi-thin sections were incubated over night with primary antibodies at 4 °C (Santa Cruz Biotechnology Inc., Santa Cruz, Calif., USA). The antibody dilutions used were alkaline phosphatase (ALP) 1:100, osteopontin (OPN) 1:100, osteocalcin (OSC) 1:100, and tatrate resistant acid phosphatase (TRAP) 1:100.
The obtained semi-thin sections were evaluated wit...
Twenty-six weeks after the regenerative procedure the patient returned for the re-entry intervention for placement of dental implants. After raising full-thickness flaps, the augmented area was exposed and horizontal crestal width measurements were performed. Then, the surgeon evaluated the bone availability and if implant placement was considered possible, a core bone biopsy was harvested with th...
CCXBB (Bio-Graft® Geistlich Pharma) is a bone substitute material in a natural block form. The dimensions of the Bio-Graft block are 10 mm in height, 10 mm in length and 5 mm in width.

The present manuscript reports the histological outcomes of a prospective single arm study evaluating the safety and clinical performance of CCXBB blocks when used as replacement bone grafts for lateral bone augmentation prior to staged implant placement.

In conclusion and within its limitations, the present clinical study revealed that TR grafts may be associated with improved SA26 values following lateral alveolar ridge augmentation.
When further analyzing the present data, it was also noted that both TR and AB grafts were associated with comparable BI26 values, thus corroborating the clinical observation of a firm graft connection to the host bone at 26Â weeks, which allowed for a proper placement of adequately dimensioned titanium implants at all sites investigated [9]. The regression analysis also revealed that BI26 values ...
The present analysis aimed at assessing and comparing CBCT outcomes following lateral alveolar ridge augmentation using TR and AB grafts. After a healing period of 26Â weeks, it was observed that TR grafts were associated with significantly higher mean SA26 values when compared with the AB group. A similar tendency was also noted for mean BI26 values; however, this difference did not reach statist...
Mean CWb and GT values were comparable in both groups and amounted to 4.53 ± 1.54 mm (median 4.50; 95% CI 3.68, 5.38) and 5.66 ± 1.75 mm (median 5.0; 95% CI 4.69, 6.64) in the TR group and 5.26 ± 1.25 mm (median 5.00; 95% CI 4.57, 5.95) and 4.96 ± 1.75 mm (median 5.0; 95% CI 4.24, 5.68) in the AB group, respectively. Between-group differences did not reach statistical signi...
All measurements were performed by one previously calibrated investigator.
The sample size calculation considered a standard normal distribution (type I error set at .05; type II error set at .20) and a sigma which was estimated based on the standard deviations observed in a recent preclinical animal study [4]. The clinical width of the alveolar ridge was defined as the primary outcome variable, ...

This analysis was based on the radiographic (i.e., cone-beam computed tomographic—CBCT) data derived from a prospective controlled clinical monocenter study including a total of 30 patients [9]. Each participant exhibited either a tooth gap or a free-end situation with an inadequate horizontal ridge width and was in need of an implant-supported fixed restoration.
In brief, lateral ridge augment...
Autogenous bone (AB) blocks harvested from intraoral donor sites (i.e., retromandibular, chin) are the most commonly used procedure for lateral alveolar ridge augmentation [1]. However, despite significant horizontal bone gains, cortical bone blocks were noted to undergo an incomplete replacement resorption [2, 3], thus featuring a composition of non-vital residual and newly formed vital bone in t...
To assess and compare the radiographic outcomes following lateral alveolar ridge augmentation using autogenous tooth roots (TR) and autogenous bone (AB) blocks.
In a total of 30 patients, lateral ridge augmentation was conducted in parallel groups using either (1) healthy autogenous tooth roots (e.g., retained wisdom or impacted teeth) (n = 15) or (2) cortical autogenous bone blocks harvested...
