Usefulness of customized titanium plates for midface contouring surgery

“…On the other hand, a CTP fabricated with additive manufacturing not only has the advantages of titanium, such as biocompatibility and mechanical strength, but also has flexibility in terms of the design and screw fixation that facilitates accurate fixation to recipients. A CTP is particularly considered effective for mandibular reconstruction due to its mechanical properties [8] . However, to our knowledge, there is limited evidence of its use in midface reconstruction.…”

Additively manufactured metallic biomaterials

“…Conventional surgical approaches rely on reconstruction Ti plates and autograft bone substitutions. Patients going through the operation utilizing conventional replacement methods suffer from complications such as joint pain, lower mouth opening range, asymmetric facial contour, and implant loosening [ 341 , 342 ]. To improve surgical outcomes, the use of AM for fabricating mandibular prostheses has been researched.…”

“…To improve surgical outcomes, the use of AM for fabricating mandibular prostheses has been researched. Xia et al [ 342 ] conducted a case study where additively manufactured metal prostheses in mandible surgery were evaluated and compared to that of conventional methods. In this study, a total of 20 patients were selected.…”

A Review on Development of Bio-Inspired Implants Using 3D Printing

“…In addition, the patient satisfaction post-implantation was found to be significantly higher with 3D printed mandibular implants compared to conventional approaches, such as titanium reconstruction plates and autologous grafting. Furthermore, the facial symmetry can be restored, and AM mandibular implants offer maximum mouth opening and occlusal function compared to conventional approaches [ 204 ]. In the study by Yan et al, four patients with ameloblastoma and squamous cell carcinoma were recruited to receive a custom EBM-printed titanium mandibular implant.…”

“…The test group had a mean operative time of 130 min and an average follow-up of 12 months, with normal maximum mouth opening ranging from 25 to 40 mm. All patients had a satisfactory postoperative dental rehabilitation when considering criteria, such as speech, chewing pain, occlusal force, swallowing, or eating difficulty [ 204 ]. In another case study by Park et al from 2020, a 53-year-old male patient suffering from osteoradionecrosis received an SLM-printed titanium implant with premounted dental fixtures.…”
