Osseointegration is derived from the Greek osteon, bone, and the Latin integrate, to make whole. It is the phenomenon responsible for formation of a direct contact between titanium dental implants and the bone which they are placed. The bone grows right up to the surface of the dental implant, without an intervening layer of soft tissue. developing a close bond and fixing the dental implant in place.
History of Dental Implant Osseointegration
Implant osseointegration was first discovered in the 1950’s by Swedish orthopaedic surgeon Per-Ingvar Brånemark. fHe used a titanium implant chamber to study the blood flow in Rabbit bone. However, when he tried to remove the implant he was unable as it had completely fused to the bone and called his finding “osseointegration”. His theory suggested that titanium oxide permanently fuses with the bone, fixing the implant in place. In 1965 Brånemark placed the first dental implants into a human patient, inventing a new treatment option that would dramatically change the field of dentistry.
Factors influencing Osseointegration
Once a dental implant has been installed and bone starts to grown into it, it’s impossible to remove the implant without damaging the bone. The degree in which the bone is integrated with the implant is affected mainly by the following factors:
- Dental Implant Material – It was originally believed that osseointegration was unique to titanium of a high purity, however while this forms to the basis of dental implant treatment today there are a wide range of materials that can integrate with bone. Other materials include Zirconium dental implants and certain ceramics such as hydroxyapatite however these have not been extensively researched in a clinic environment.
- The surface and structure of the implant – The ability of highly pure titanium to osseointegrate so well with bone is thought to be due to the titanium oxide layer that forms on the surface of the implant, described as being osseoconductive as it’s conductive to bone formation. Modifications of the surface of the implant have been made by multiple dental implant manufacturers to increase its biocombatibility and speed up the rate of osseointegration.
- Heat – Heating of the bone during implant surgery to temperatures of more than 50oC can result in cell death and preventive the osseointegration of implants. Great care is taken at implant sites to prevent an increase of temperature, which has led to intelligent drill speed design.
Other Applications of Osseointegrated Implants
The advantages of Osseointegration aren’t just utilised in Dental Implants, the potential in the field of prosthetics is limitless. With osseointegrated prosthetics, prosthetic limbs can be integrated into the bone allowing them to seat firmly without causing pain or limiting a patients freedom of movement. In the case of severely broken bones rods can be osseointegrated to stabilise the bone while it heals and adds support to prevent the bone being broken again. The process of osseointegration has also been used in artificial ears, eyes and noses with a high degree of success.
What started off with a rabbit has led to an advance in dentistry that allows patients to replace their missing teeth effectively. The osseointegration of dental implants into the bone of a patients jaw allows significant load bearing, allowing them the freedom to eat most foods and making dental implants the best solution in replacing missing teeth.
The birmingham dental hospital lies in the heart of Birmingham, treating over 130,000 patients a year and helping patients with emergency dental treatment every day of the week. The first original dental hospital was create in 1858, and the current building is the 6th replacement built in the 1960’s. The dental hospital employs 400 NHS workers and 300 university staff, making it one of the largest denial hospitals in the UK. Long-awaited Plans are in place to create a new dental hospital, which could open as early as 2014 if it receives treasury backing.
The current Dental Hospital was designed in the 1960s, dentistry was changed since then. The old 10 floor building will be replaced with a new building of fewer floors which will be larger in size. This is planned to make the hospital more cost effective to run. The new hospital will contain 159 dental chairs, a 10% reduction of the previous number from the current dental hospital.
The Scott Arms Dental Practice has assisted the Birmingham Dental Hospital on bank holidays and weekends by providing the emergency dental service in the past. Between 1992 and 1997 the Scott Arms Dental Practice was the official emergency dental service for the health authority. We have provided our emergency service for more than 18 years, treating over 100,000 patients.
The Birmingham Dental Hospital is based in Birmingham city centre and provides dental emergency care for the general public in the Birmingham / West Midlands area . This service operates 9.00am-4.30pm from Monday-Friday. Outside these hours there is a basic emergency service running from 6.30pm till 8.30pm weekdays and 9.00am-11.30 am on weekends.
Many patients who have tooth ache outside of these hours seek dental treatment from other dental practices. One of the main dental services here, which provides additional services, is Scott arms dental practice. This practice is open till 11.00pm, 7 days a week / 365 days per year.
There are 2 types of emergency treatment, one of them being rapid swelling, affecting the patients breathing, and excessive bleeding from an extraction socket site. The second is urgent treatment, which is acute pain from toothache or minor trauma related incidents.
The dental hospital during normal working hours will cater for both of these dental emergencies, however outside these hours, emergency treatment as described above would require treatment at the Queen Elizabeth hospital in Edgbaston. Urgent dental treatment, as described above, including regular toothache can be treated by other general dental practitioners.
It is a known fact that Dental Implants are the perfect way to replace a missing tooth. We recently received some testimonials from patients who had received Dental Implant treatment in Birmingham from us and they are available to be seen on our website. Stay tuned for more dental implant testimonials over the upcoming month.
