In conclusion, the findings of this case series based on dental implants that had to be retrieved because of advanced peri-implantitis and the concomitant inflammatory osteolysis suggest that the residual peri-implant bone might accumulate the functional load and is consequently modeled and reinforced to become cortical bone.

When further interpreting the present study, the peri-implant osteocyte lacunae density after 1 to 27 years in function was reported [28]. In line with our findings, empty osteocytic lacunae adjacent to zirconia implants diagnosed with peri-implantitis were described [29]. Based on counting the osteocyte lacunae, we observed that numerous filled but also empty osteocytic lacunae were present withi...

Discussion : Histological characteristics of advan...

The present study was inspired by the concept that upon advanced loss of cortical peri-implant bone, the remaining peri-implant trabecular bone is subjected to masticatory forces and reinforced as a consequence of functional adaptation [15]. This adaptation depends on vital osteocytes [16]. Therefore, the present human case series aimed at investigate the peri-implant bone in advanced peri-implant...

The clinical and radiographic characteristics of the implant sites are presented in Table 1. In total, 3 implants were located in the maxilla, while two implants were located in the mandible. While all implants showed bleeding on probing, only 2 implants presented with suppuration on gentle probing. Mean probing depth was 6.3 ± 0.4 mm corresponding to a mean marginal bone loss (MBL) of 4.7 ± 1.0...

RB was divided into 500-μm-wide horizontal zones (from BD to A) following the long axis of the implant. For each of these individual zones, BIC and bone density (B.Ar/T.Ar) were determined. Osteocyte and empty osteocytic lacunae were counted along the region of interest (ROI) (i.e., the area encompassing the intra-thread regions along the buccal RB extension) (Fig. 1) using a software program (Im...

Cone beam computed tomographic (CBCT) scans were obtained from each patient for the surgical planning of implant removal. Linear measurements of the defect length (DL) at affected implants were made by drawing a vertical line, following the long axis of the implant, from the implant shoulder (IS) to the bottom of the defect (BD) at buccal and oral aspects in the CBCT data sets (Implant viewer, ver...

Peri-implantitis was recently defined as a “pathological condition occurring in tissues around dental implants”, which is “characterized by inflammation in the peri-implant connective tissue and a progressive loss of supporting bone” [1,2,3,4]. Human biopsies confirmed the presence of plasma cells, macrophages, and neutrophils [5] and elevated expression of inflammatory cytokines [6, 7] a...

Inflammatory osteolysis is the clinical hallmark of peri-implantitis. The morphology of the remaining peri-implant bone and the level of osseointegration, however, remain unknown. Our aim was to characterize advanced peri-implantitis bone defects in humans. Four patients (3 female and 1 male) were diagnosed with peri-implantitis. A total of 5 implants with machined surfaces and a mean loading tim...
