“…Some dental surgery patients have suffered from loss of teeth combined with extensive alveolar bone defects caused by tumors, trauma, or severe periodontal disease [ 1 , 2 ]. To repair the biological and functional loss of the oral cavity, comprehensive reconstruction procedures, including implantation of multiple dental implants, are frequently performed [ 3 , 4 ].…”

In Vivo Evaluation of 3D-Printed Polycaprolactone Scaffold Implantation Combined with β-TCP Powder for Alveolar Bone Augmentation in a Beagle Defect Model

Insufficient bone volume is one of the major challenges encountered by dentists after dental implant placement. This study aimed to evaluate the efficacy of a customized three-dimensional polycaprolactone (3D PCL) scaffold implant fabricated with a 3D bio-printing system to facilitate rapid alveolar bone regeneration. Saddle-type bone defects were surgically created on the healed site after extracting premolars from the mandibles of four beagle dogs. The defects were radiologically examined using computed tomography for designing a customized 3D PCL scaffold block to fit the defect site. After fabricating 3D PCL scaffolds using rapid prototyping, the scaffolds were implanted into the alveolar bone defects along with β-tricalcium phosphate powder. In vivo analysis showed that the PCL blocks maintained the physical space and bone conductivity around the defects. In addition, no inflammatory infiltrates were observed around the scaffolds. However, new bone formation occurred adjacent to the scaffolds, rather than directly in contact with them. More new bone was observed around PCL blocks with 400/1200 lattices than around blocks with 400/400 lattices, but the difference was not significant. These results indicated the potential of 3D-printed porous PCL scaffolds to promote alveolar bone regeneration for defect healing in dentistry.

“…Adequate bone volume in both horizontal and vertical dimensions plays a vital role in achieving long-term aesthetic and functional results in implant dentistry [1]. However, in our daily work, many patients suffer from horizontal or vertical bone deficiency, especially in cases of long lasting edentulous ridges or bone defects caused by trauma.…”

Individualized titanium mesh holds many advantages over conventional mesh. There are few reports in the literature about the effect of mesh pore size and mesh thickness on the mechanical properties of titanium mesh. This study is designed to develop an individualized titanium mesh using computer-assisted design and additive manufacturing technology. This study will also explore the effect of different thicknesses and pore sizes of titanium mesh on its mechanical properties through 3D FEA. According to this study, the mechanical properties of titanium mesh increased when the thickness decreased (0.5 mm to 0.3 mm). With an increase in mesh diameter (3 mm to 5 mm), the mechanical properties of mesh decreased. The diameter of titanium mesh has less influence on its mechanical properties than does the thickness of the mesh. Titanium mesh with a thickness of 0.4 mm is strong enough and causes less stimulation to mucosa; therefore, it is more suitable for clinical use. In addition, parameters of titanium mesh should be decided clinically according to bone defect size, defect location, and force situation.

“…In the case of deficient alveolar ridges, bone volume can be increased by an augmentation with autologous bone rings [2] or autologous bone grafts, because the use of body´s own tissue is the safest and most compatible method for the patient [3,4]. For larger defects, whole bone blocks are transplanted, which have to be removed from the patient elsewhere [5]. Compact bone blocks can be obtained from the iliac crest or the tibia head, with or without cancellous portions, while using trephines.…”

“…A relatively simple method to obtain autologous particulate bone-grafting material is the removal from the retromolar region or the chin region by using bone scrapers or raspatories. The major disadvantage of this method is the fact that these bone chips that ablated from the surface of the bone consist of cortical cells that have lower regenerative potential than cells that reside in underlying cancellous bone [5]. Anyway, it is proven that these manual or piezoelectric instruments can be safely used for sinus floor augmentation [8].…”

Bone drill chips that are collected during implant site preparation can be reused as autologous bone-grafting material for alveolar ridge augmentation. This study characterized five market-leading implant drill sets regarding their geometric properties and ability to produce vital bone chips. The drill geometry of each tool of five commercial implant drill sets was characterized while using optical profile projector devices and SEM. Bone chips were collected during the in vitro preparation of porcine jaw bone with the various drill sets. Produced bone chip masses were measured. The bone chips were cultured in vitro and the number of outgrown cells was determined and measurand for vitality. Furthermore, the thrust force and cutting torque were recorded to examine the mechanical loads of the manual drilling process. The tool geometry and set configuration of one out of five implant drill sets appears to be superior regarding chip mass, vitality, and thrust force. It could be proven that there is a correlation between vitality and thrust force. The thrust force is influenced by the cutting behavior of the tool, which in turn depends on the geometry of the tool. The tool geometry has an influence on the vitality of the augmentation material due to this relationship.
