| Kim et al. [123] | Guided tissue regeneration (In vivo) | Not applicable | Laser scanning | Not mentioned | PCL, HA | 3D printing | After 9 weeks, a putative periodontal ligament and native alveolar bone were regenerated at the interface incisor scaffold |
| Park et al. [195] | Scaffold for alveolar bone regeneration (in vivo) | Not applicable | CT | Not mentioned | PCL | 3D bioprinting system (laboratory-made system in Korea Institute of Machinery and Materials, Korea) | New bone was formed adjacent to the scaffold
PCL blocks with 400/1200 lattices were inclined to more new bone formation |
| Rasperini et al. [196] | Scaffold for periodontal repair | 1 | CT | NX 7.5 (Siemens PLM Software, USA) Mimics (Materialise, USA) | PCL | SLS (Formiga P100 System; EOS, Germany) | After 12-month follow-up, the patient gained a 3 mm clinical attachment and partial root coverage
After 13-month follow-up, the scaffold was exposed |
| Lei et al. [197] | Guided tissue regeneration | 1 | CBCT | Mimics (Materialise, Belgium) | Biocompatible material (MED 610) | PolyJet (Objet Connex 350, Stratasys, USA) | After 3 months, the probing pocket depth was greatly reduced
After 6 months, bone was regenerated by the assessment of radiography |
| Pilipchuk et al. [198] | Scaffold for dentin, ligament, and bone regeneration (in vitro & in vivo) | Not applicable | Not mentioned | NX 7.5 (Siemens PLM Software, USA) | PCL, HA | SLS | Groove microdepth was a more important parameter than width for promoting formation of cell alignment and increasing oriented collagen fiber density |
