Cranioplasty is the surgical repair of acquired or congenital defects of cranium.[1] Archeological evidences suggest that in prehistorical era , cranial defect reconstruction was done with gold, silver and shells. Later it was followed by the use of bone grafts, metal and plastics.[2,3]Apart from metals like titanium, Polymethylmethacrylate (PMMA) is the latest material being used for cranioplasty. It was first utilized in 1940 and can be moulded intraoperatively by hands or using 3D printed models into the shape of a cranial defect.[4]
Prefabricated Titanium implants have been successfully solving this purpose of cranioplasty ,but are quite expensive especially in developing countries. In modern era, for getting desired shape, size and better cosmetic results, the use of three-dimensional (3D)

Alloplastic material is required when autogenous bone is not available as in calvarial tumour resections, bone infections or bone discarded during craniectomies. Now a days PMMA and titanium are most widely used alloplastic materials. Preparation of implants can be done in two ways - by hands and by computer generated 3D models [11,12]. Hand fabrication is cheaper and less time consuming technique but desired outcome with respect to shape and size is difficult. The 3D printing technology helps us to prepare prefabricated implants or models to mould grafts intraoperatively. This method has become immensely popular as it does not require original bone flap and has produced superior fitting and cosmetic results[13].
3D printing technology is an evolving branch and its clinical application is growing rapidly. The convenience and affordability of this technology have spurred its adoption in variety of medical fields, especially in planning complex craniofacial reconstructions [14,15].
The procedure for the fabrication of medical models (templates) consists of multiple
The Dmanisi skull 4, also known as D3444 with its mandible D3900, is one of five Homo erectus skulls discovered in Dmanisi, Georgia. Described in a publication in October 2006, it is believed to be about 1.8 million years old. Dmanisi D3444/D3900 is believed to be a Homo erectus adult female with a marked edentulous (toothless) grin. The cranium (D3444) was found first in 2002 and the mandible (D3900) was found later in 2004, immediately adjacent to the spot the cranium was found. The brain has an endocranial capacity of 650 cm.
Once the digital reconstruction was done the skull was compared with those of ancient and living primates in museums
Another emerging technology is the 3D printer. The 3D printer allows people to print hearing aids, functioning prosthetic limbs, prosthetics that let people feel everything they touch with it, and replica skulls being created from patients CT
Total Hip Resurfacing With the evolution in advancement in the medical field, the old practiced of hip resurfacing is no longer active. The process is lined in such manner that the hip bone is capped and reframed through metal prosthesis. This surgery has an advantage over traditional means as the hip socket is secured by means of metal cup. It also helps in lasting longer and little discharge of metal ions during surface rubbing.
As 3D printing in the medical field is still evolving, it is unsure the long term effects. Unable to see the possible detrimental effects of artificial cells, organs, and tissues can be very dangerous. In the same way that the technology in the “Happylife home” was ultimately a fatal detriment to the Hadley family. As research proceeds more information is sure to emerge about the future of 3D printing in the medical
In the past they would not have operated on patients if the operation was to tricky, but they can now operate and help out all of their of their patients. There are about 75 hospitals in the U.S. that have 3D printers and about 200 worldwide that have 3D
3D printing makes devices accessible to others, however producing these devices, enters a medical and technical field. Unfortunately, there are many 3D printing organizations that are making devices that are not safe and will cause long-term damage. Just to give an example, the tissues in the arm are very sensitive and it requires highly technical skills and knowledge to produce devices that can work properly for the patients, especially for the upper limb. Meaning, hands, and arms, which is what Enable Community Foundation focus on. Otherwise, patients will have long-term medical consequences such as back problems, or will abandon the devices.
The corkscrew end of the implant fitted into the thigh bone, while the other end which fitted into the shin bone had three projections which would prevent
The Progression of Prosthetics Hannah Rowe Madison High School Mr. Snelgrove March 26, 2018 Abstract This paper covers the progression of prosthetic limbs over the years, as well as how the technological advancements of prostheses can affect someone’s life who has suffered from limb loss. It goes over the benefits and disadvantages of having a prosthetic limb, and a portion of the process of what it takes to create an artificial limb.
With the help from the team of designers and technicians, Open Bionics built authentic looking prosthetics that
Relaxed in the dental chair with my dark glasses on, I had been prepped and was ready for my second surgery. My headphones played beautiful, calming classical music. A micro-current patch placed behind each of my ears would help to keep me in a relaxed state. I could taste the remnants of the orange flavored supplements used to promote the relaxation response. My biological dentist and his assistant talked in the background as we waited for the anesthetic to take effect.
You have heard about the amazing affect prosthetics have had on all different kinds of people! Advancements in prosthetics are being made currently and will continue for years to come. A world without prosthetics is unimaginable for so many people. They give hope to amputees, disease survivors, people who have been paralyzed, and so many others. Can you even believe how important prosthetics are for this many people?
According to The Bureau of Labor Statistics(BLS), there is an 18% job outlook and is growing “faster than average” between the time of 2012-2022. The increase in job opportunities means there will be more insurance in obtaining and keeping a job, in fact there will be about 124, 000 more jobs available for surgeons by the end of the ten year range according to BLS. Not only is the plastic surgeon group growing, many subsections are available, which allows many doors to be opened. Some of the plastic surgery subcategories, “including cranio-maxillofacial surgery, microvascular surgery, hand surgery”(Maser). Hand surgery is focused on improving and changing the shape and structure of a hand while allowing it to still function properly.
Group 1: Twenty five eyes for which a deep anterior lamellar keratoplasty was done using double bubble modification of the big bubble technique as described by Foroutan and Dastjerdi (2007). All cases were operated by a single experienced anterior segment surgeon. The recipient operative procedure was done first before stripping the descement membrane from the donor so as not to lose the graft if large DM perforation occurred and the surgeon decided to covert to PKP and it was done as follows: 1- Moxifloxacin HCl ophthalmic solution 0.5% was administrated for one to two days preoperatively, four times daily, to reduce the risk of infection.
Fix or replace damaged tissue; biology has always been the main concern for scientists. Today, the most important instrument for tissue engineering scientists to produce replacement tissues and implants to repair or replace damaged tissue. Tissue engineering is generating a new field of study in which the principles of engineering and biology to correct the damaged tissue, uses and can renewal, operation and maintenance of tissue healing. In order to use an ideal scaffold Tissue engineering should have features such as non-toxic Cell and tissue properties to be fit.
