“…As a consequence of fibroblast invasion and micro‐movement of the device, the pseudo‐periosteum may occupy the osteogenesis space for 0 to 2 mm thickness in the clinical observation 26,28,29 . As described by Cucchi et al, 26 pseudo‐periosteum was classified into three types: Type 1 (no tissue or tissue <1 mm); Type 2 (regular tissue between 1 and 2 mm); and Type 3 (irregular tissue or tissue >2 mm) 26 . In the analysis of digital models in 16 cases, the thickness of new bone had been averagely reduced 0.55 ± 0.53 mm comparing with the post‐GBR models.…”

“…Secondly, as many authors have reported, the so‐called pseudo‐periosteum (connective tissue layer) underneath Ti‐mesh had been observed at every GBR sites, which may be a relevant factor for the accuracy of bone regeneration 9,21,25‐27 .

Background Few studies have focused on the dimensional accuracy of customized bone grafting by means of guided bone regeneration (GBR) with 3D‐Printed Individual Titanium Mesh (3D‐PITM). Purpose Digital technologies were applied to evaluate the dimensional accuracy of customized bone augmentation with 3D‐PITM with a two‐stage technique. Materials and methods Sixteen patients were included in this study. The CBCT data of post‐GBR (immediate post‐GBR) and post‐implantation (immediate post‐implant placement) were 3D reconstructed and compared with the pre‐surgical planned bone augmentation. The dimensional differences were evaluated by superimposition using the Materialize 3‐matic software. Results The superimposition analysis showed that the maximum deviations of contour between were 3.4 mm, and the average differences of the augmentation contour were 0.5 ± 0.4 and 0.6 ± 0.5 mm respectively. The planned volume of bone regeneration was approximately equal to the amount of regenerated bone present 6 to 9 months after the surgical procedure. On average, the vertical gain in bone height was about 0.5 mm less than planned. And, the horizontal bone gain on the straight buccal of the dental implants and 2 to 4 mm apical of the platform fell also about a 0.5 mm short on average. Statistically significant differences were observed between the augmented volume of virtual and post‐GBR, and the horizontal bone gain of post‐implantation on the level of 4 mm apical to the implant platform (P < .05). Conclusions The dimensional accuracy of customized bone augmentation with the 3D‐PITM approach needs further improvement and compared to other surgical approaches of bone augmentation.

“…The thickness can range from 1.0 mm to 0.3 mm, influencing stiffness, malleability, and flexibility of the mesh for better adaptation to the bone deficiencies and to provide the appropriate resistance to mechanical strains. Moreover, the virtual planning must consider the connective tissue that develops between the mesh and the regenerated bone, so-called pseudo-periosteum [ 27 ]. As observed in different clinical trials, not all the space under the mesh is filled by newly-formed bone but only about 90% of the planned bone volume is formed, while the rest is represented by connective tissue; for this reason, it is recommended to consider the possibility of over-contouring the mesh during the virtual planning of the bone regeneration.…”

“…The following parameters were recorded between T0 and T1: quadrant of interest, defect type (horizontal/vertical), periosteum type [ 26 ], membrane application, planned bone volume (PBV), surgical complications, and above all healing complications. During the re-entry surgery (T1), the data collection included bone density, pseudo-periosteum type [ 27 ], number of implants inserted, implant stability, vertical bone gain (VBG), lacking bone volume (LBV), regenerated bone volume (RBV), and regeneration rate (RR = RBV/PBV.100). Finally, implant and prosthetic success were evaluated during the follow-up period according the to the criteria described by Buser et al in 1994 [ 28 ], and modified by Albrektsson & Zarb in 1998 [ 29 ].…”

Background One of the most recent innovations in bone augmentation surgery is represented by computer-aided-design/computer-aided-manufacturing (CAD/CAM) customized titanium meshes, which can be used to restore vertical bone defects before implant-prosthetic rehabilitations. The aim of this study was to evaluate the effectiveness/reliability of this technique in a consecutive series of cases. Methods Ten patients in need of bone augmentation before implant therapy were treated using CAD/CAM customized titanium meshes. A digital workflow was adopted to design virtual meshes on 3D bone models. Then, Direct Metal Laser Sintering (DMLS) technology was used to produce the titanium meshes, and vertical ridge augmentation was performed according to an established surgical protocol. Surgical complications, healing complications, vertical bone gain (VBG), planned bone volume (PBV), lacking bone volume (LBV), regenerated bone volume (RBV), average regeneration rate (RR) and implant success rate were evaluated. Results All augmented sites were successfully restored with definitive implant-supported fixed partial dentures. Measurements showed an average VBG of 4.5 ± 1.8 mm at surgical re-entry. Surgical and healing complications occurred in 30% and 10% of cases, respectively. Mean values of PBV, LBV, and RBV were 984, 92, and 892 mm 3 , respectively. The average RR achieved was 89%. All 26 implants were successfully in function after 1 year of follow-up. Conclusions The results of this study suggest that the bone augmentation by means of DMLS custom-made titanium meshes can be considered a reliable and effective technique in restoring vertical bone defects.

“… 20 Study observed that after alveolar ridge reconstruction conducted by titanium mesh, a thin layer of 1–2 mm thick, soft tissue can often be found upon the regenerated bone surface, called “pseudo-periosteum”. 21 The formation of this soft tissue layer may be related to the insufficient cell exclusion ability of titanium due to its pores. The role of pseudo-periosteum may be related to bone graft protection, graft infection prevention, and absorption.…”

Titanium mesh for bone augmentation in oral implantology: current application and progress

Guided bone regeneration (GBR) is an effective and simple method for bone augmentation, which is often used to reconstruct the alveolar ridge when the bone defect occurs in the implant area. Titanium mesh has expanded the indications of GBR technology due to its excellent mechanical properties and biocompatibility, so that the GBR technology can be used to repair alveolar ridges with larger bone defects, and can obtain excellent and stable bone augmentation results. Currently, GBR with titanium mesh has various clinical applications, including different clinical procedures. Bone graft materials, titanium mesh covering methods, and titanium mesh fixing methods are also optional. Moreover, the research of GBR with titanium mesh has led to multifarious progresses in digitalization and material modification. This article reviews the properties of titanium mesh and the difference of titanium mesh with other barrier membranes; the current clinical application of titanium mesh in bone augmentation; common complications and management and prevention methods in the application of titanium mesh; and research progress of titanium mesh in digitization and material modification. Hoping to provide a reference for further improvement of titanium mesh in clinical application and related research of titanium mesh.
