The completed restoration is a stable implant/tooth restoration. The bite has been opened from the pre-operative condition. The patient's anterior teeth have stabilized and are deemed maintainable at this point in time, although future work may involve the replacement of the maxillary anteriors. Photo and x-ray on this page show a three year result.
This is some blog description about this site
A dental implant is really a very simple metal screw which is designed to thread into the bone of the jaw and to allow for the attachment of a (prosthetic) tooth at the top. Implants are made of Medical grade Titanium or Titanium Alloy. Your dentist will purchase the implants in sterile packaging and place them in a small hole in the bone which he or she has prepared as part of the implant placement procedure. The bone will fuse to the implant over a short period of time in a process referred to as 'osseointegration' and once this process is successfully completed (3 to 4 months) the implant is permanently in place.
Bone Grafting Explained Materials
When there is adequate bone height and width and when the density of the bone is acceptable, implant placement and ensuing success is almost a foregone conclusion. However, many of our patients are deficient in bone and in order for the implant placement to be successful, we have to select a means of regenerating this missing bone. While this is not necessarily an easy task, it does have a high degree of success when carried out with skill and knowledge. This short article will exam the materials that are used in bone regeneration and some of the latest techniques for accomplishing this minor miracle.
Autogenous Bone - Generally considered the best material for bone grafting. In many implant procedures, bone for this purpose can be secured from adjacent sites, the chin, the tuberosity and occasionally from the hip or other areas of the body.
Allografts - They are derived from genetically unrelated members of the same species. This is generally Cadaver bone which has been specifically prepared for this purpose, Freeze dried cortical bone is in this category.
Xenografts - Bone derived from other species such as cows. Bio-Oss (Osteohealth - Shirley, NY) is a popular one at this time. These materials generally work via either Osteoconduction, the formation of new bone from host cells along a framework of a compatible alloplast, or biological material, or Osteoinduction, the formation of new bone from the biomechanically differentiation of the host mesenchymal cells. Bone Morphogenic Protein (BMP) is the material that will stimulate osteoinduction and the research that is currently ongoing gives us great hope of being able to use BMP to predictably and very rapidly induce the growth of bone just about anywhere we want it.
Biological Width - Dental Implants
The phenomenon of the establishment of a zone of biological width has been with use for many years in dentistry. In its most simplified form, biological width is defined as the distance necessary for a healthy existence of bone and soft tissue from the most apical extent of a dental restoration. In a more complex form, the definition states that there must not be any encroachment of a restorative margin within two millimeters of the bone that surrounds the tooth...
The problem is not the restoration per se, but rather, the bacteria which will always find shelter in the interface between the restorative margin and the tooth structure. The presence of bacteria and their associated toxins within approximately 2mm of the boney margin will cause and inflammatory response in the soft tissue and an eventual apical migration of the entire periodontal complex (gingiva, periodontal ligament and bone).
The purpose of this paper is to discuss the phenomenon of biological width as it pertains to dental implants and to look at any contributing factors in the re-establishment of biological width that may be attributed to dental implants alone.

I have just retired from the practice of dentistry and have taken on an entirely new project. For years, I have developed and administered www.dental-implants.com. The site has been very useful in providing patients to my practice. It has been consistently highly ranked in the Google Indexes and patients have contacted me from all over the world.
I have recently turned the site into a referral service for patients looking for dental implants. I’m still working on the programming and the appearance of the site, but right now, I think we have it looking and working pretty good. Now we need some Beta Testers and I was hoping that you could go through the site and check it out. I would like you to register on the site and fill in all the information (I can take it off later if you like). I would like you to see if everything makes sense and that you can follow the thought processes behind the site. Of course, look for typos and grammatical errors as well… Any thing you can find that you think needs work.
The site is www.dental-implants.com. Look at it and register as a dentist and we will talk. I will be selecting a number of dentists who qualify for this site to be listed for one full year at no charge so I hope I see your name on the expert Implant Dentist referral list very soon in the future.
Sincerely and with great appreciation,

Dr. Brånemark changed my life in 1984 with his introduction to a workable dental implant, an implant with up to a 98% success rate. Before his research, implants had an extremely high failure rate and were not really usable for our patients. Dr. Brånemark developed and nurtured modern dental implantology. He taught dentistry how to truely help our patients and how take hopeless situations and turn them into success. He will be missed.
The beta tests for Dental-implants.com are proceeding and I want to thank all of you who have responded. This type of testing allows us to find and correct errors on the site and to get a much better flow of the material. I'm still looking for qualified dentists to register and be approved for a free 6 month position on the site. If you have any questions, just send me an email and I'll get right back to you.
The new www.dental-implants.com site is now live and we would like a little help troubleshooting the site and getting it to work perfectly. I would appreciate it very much if people would go to the site and register as patients or doctors so that we can see if everything is working. There are no charges or obligations to any of you who register.
In the meantime, I am constantly working on the site, adding material and fine tuning. I rfeally hope you like it but I would appreciate the feedback whether pro or con...
In 1984, the modern dental implant concept was introduced to North America by Dr. P. I. Brånemark of Sweden. His research and design produced an elegant dental implant system which boasted up to a 98% success rate for patients who were missing their teeth. Since that time, there has been a huge amount of research and development with dental implants and the net result can sometimes be very confusing for the patients (and even the dentists). Couple this with the amount of advertising to promise things like “teeth in an Hour” and “Same Day Teeth”, the patient gets lost in a quagmire of claims and bravado that would leave anyone confused as to who on should see to get these types of advanced dental procedures.
The problem can sometimes be solved by asking your general dentist for a recommendation for dental implant placement and restoration. More often, this approach is complicated by the fact that the Generalist might not be well versed in these techniques and might not know who is really adept in this area. There are on-line referral services, but these, to date, only recommend dentists who pay them and there is absolutely no other qualifying procedures!
Enter dental-implants.com… Yes, our dentists do pay to be listed on this site, but the difference here is that they have to be totally qualified before they are allowed to do so. We look at their education and training and we examine their experience in this area of dentistry very carefully to determine if they meet our standards. We may even do on site visits to experience for ourselves how these dentists interact with their patients! We are very thorough about qualifying each dentist who appears on this site and our intention is to help direct you to someone who has the training and experience to provide you with a great outcome.
Finding a qualified dentist to place and restore your dental implants is the first step that each patient must deal with in the quest to replace missing or damaged teeth. A Dental Specialist with lots of training and experience will insure that your implant experience is successful and long lasting. Referral Services do exist, but they have no means of qualifying the dental practitioner other than collecting a fee for the services. This does nothing to insure that the patients actually get the best care.
Dental-Implants.com qualifies each and every dentist that we list as a potential provider for you. We interview each dentist. We verify their training and experience as well as investigating their present licensing. In many cases, we might actually visit their dental offices and observe the working of their dental practice and the interactions of their staff. In the end, we give you a definitive picture of each dental practitioner and what he or she might provide for you so that you have a place to start with your plan to restore your teeth with dental implants. And, the best part, this service is totally free to patients.
