Skull defects usually create aesthetic and functional disturbances to the patient. These defects are currently reconstructed by using computer‐aided design and manufacturing processes. Classification of skull defects becomes important in discussing the complexity of reconstruction in clinical practice or comparing clinical results in scientific articles.

Computer-Aided-Design/Computer-Aided-Manufacturing Titanium Cranioplasty in a Child: Critical Appraisal.
TLDR
The authors present a case of a 9-year-old boy, where cranioplasty using a CAD/CAM additive manufactured titanium implant led to improvement of symptoms attributed to cerebrospinal fluid circulation problems and intracranial homeostasis disbalance. Expand

TLDR
This report details the usual procedures for skull reconstruction, as well as the advantages and limitations of the different materials and operative strategies. Expand
Custom implant design for large cranial defects
TLDR
The results show that the CAD tool presented can generate patient-specific implants with high accuracy, and a combination of geometric morphometrics and radial basis functions, namely thin-plate splines, allows semiautomatic implant generation. Expand
Simultaneous repair of two large cranial defects using rapid prototyping and custom computer-designed titanium plates: a case report
TLDR
A 28-year-old woman who underwent a corpus callosotomy for medically intractable epilepsy was presented with a case where two relatively large, adjacent cranial defects were repaired by custom computer-designed titanium plates. Expand
The therapeutic effect of patient-specific implants in cranioplasty.
TLDR
Reconstruction of skull bone defects with PEEK and titanium patient specific implants gave a statistically significant improvement in quality of life, decreased pain and headaches and gave aesthetically good results. Expand
Cranioplasty with patient-specific implants in repeatedly reconstructed cases.
TLDR
Treatment of skull bone defects in repeated reconstruction requires an optimal preoperative planning and intraoperative procedure, and no significant differences in the duration of the surgical procedure nor costs of obtaining the PSIs are found. Expand
Patient‐specific reconstruction with 3D modeling and DMLS additive manufacturing
Purpose – The purpose of this paper is to develop a workflow for 3D modeling and additive manufacturing (AM) of patient‐specific medical implants. The comprehensive workflow consists of four steps:Expand

Titanium in reconstructive surgery of the skull and face.
TLDR
The use of titanium for cranioplasty and malar defects and the technique used to fashion these prostheses in a centre which does not have the facility for producing computer-generated full-size craniofacial models has produced very satisfactory results with minimal morbidity and no complications. Expand
Custom-made cast titanium implants produced with CAD/CAM for the reconstruction of cranium defects.
TLDR
An advanced method of rapid prototyping for a fine casting process is presented, which is possible to form very thinly tapered structures and to obtain more complex geometrical structures with smaller diameters. Expand
CAD/CAM-prefabricated titanium implants for large skull defects - clinical experience with 166 patients from 1994 to 2000
TLDR
The high precision and the easy handling of these implants make them useful, especially in complicated applications with very large defects, multiple previous operations and sometimes additional irradiations. Expand
Individual Prefabricated Titanium Implants in Reconstructive Craniofacial Surgery: Clinical and Technical Aspects of the First 22 Cases
TLDR
The reconstruction of 22 posttraumatic, postoperative, or primary cranial and craniofacial defects measuring up to 18 cm was performed using this new method, and duration of surgery was reduced dramatically. Expand
Microsurgical Tissue Transfer and Individual Computer-aided Designed and Manufactured Prefabricated Titanium Implants for Complex Craniofacial Reconstruction
TLDR
From 1994 to 2000 187 individual computer-aided prefabricated titanium skull implants were inserted at 37 clinical centres, demonstrating the variability of possible combinations, which also require special timetables and principles of construction of the CAD of the implant. Expand

TLDR
The use of 3D imaging and rapid prototyping allow precise repair of large skull defects, with good aesthetic and functional results and silicone rubber moulds permit the production of very thin details needed not only for cosmetic reasons but for reconstruction plate stability as well. Expand
Synthesis of CAD/CAM, robotics and biomaterial implant fabrication: single-step reconstruction in computer-aided frontotemporal bone resection.
TLDR
A critical comparison of both implant materials and both resection types shows that fabrication of a PDLLA implant and robot resection are already possible and are more convincing due to the higher precision and practicability. Expand
Custom cranioplasty using stereolithography and acrylic.
TLDR
An original technique for the manufacture of customized cranioplastic implants has been developed and tested in 30 patients and patients reported that the opportunity to see the biomodel and implant preoperatively improved their understanding of the procedure. Expand
Geometrically structured implants for cranial reconstruction made of biodegradable polyesters and calcium phosphate/calcium carbonate.
TLDR
The aim of this study was the development of a processing pathway for manufacturing of biodegradable skull implants with individual geometry prepared by a combination of hot pressing and gas foaming to overcome problems like inflammatory reactions caused by acidic degradation products of polylactide.
