Dental implants are designed to provide a foundation for replacement teeth that look, feel and function like natural teeth. The person who has lost teeth regains the ability to eat virtually anything and can smile with confidence, knowing that teeth appear natural and that facial contours will be preserved. The dental implants themselves are tiny titanium posts that are placed into the natural bone where teeth are missing. The bone bonds with the titanium, creating a strong foundation for artificial teeth. This is called oseointegration. In addition, dental implants can help preserve facial structure, preventing the bone deterioration that occurs when teeth are missing.
Dental implants are changing the way people live! With them, people are rediscovering the comfort and confidence to eat, speak, laugh and enjoy life. If, like many others, you feel implant dentistry is the choice for you, we ask that you undergo a dental/radiographic examination and health history. During these consultation visits, your specific needs and considerations will be addressed and your questions answered. Your concerns are important to us and our team will work with you very closely to help make your procedure a success.
We can use a cat scan to help choose the best implant and define the depth, width and angulation of the implant. THis also gives the optimum effect for maximising the support, position and the number of implants and the appearance of the finished, restored tooth.

Dental implants are metal anchors, which act as tooth root substitutes. These are placed into the natural bone normally with local anaesthetic or intravenous sedation. Usually (but not always) you then have to wait three to four months before the implant can be loaded or restored. Dental implants can be used to replace one, two or all your teeth.
Small posts or “abutments” are then attached to the dental implant, which protrude through the gums. These posts provide stable anchors for artificial replacement teeth. For most patients, the placement of dental implants involves initially the assessment and treatment planning to determine the optimum placement of the implants. At this time we may take a Cat scan which enables us to see the available bone in three dimensions. We can then plan your treatment precisely on the computer and explain to you and refine the choices and agree how best to proceed. The in house Cat Scan allows us to determine the amount of bone and the best dimension o the best suited implant to maximise your chance of long term success. Usually this is then followed by two surgical procedures.
First, dental implants are placed. For the first three to four months following placement, the dental implants are beneath the surface of the gums gradually bonding with the natural bone. This process is called osseointegration. You should be able to wear temporary dentures or a temporary bridge and eat a reasonable diet during this time.
After the dental implant has bonded to the natural bone, the second phase begins. Your oral surgeon will uncover the dental implants and attach a small healing collar. Then, we will be able to begin making your new teeth. An impression must be taken. Then posts or attachments can be connected to the dental implants. The teeth replacements – either single dental crowns, multiple dental bridges or full arch options – are then made to fit over the posts or attachments.
The entire procedure usually takes six to eight months. Most patients do not experience any disruption to their daily life.
Bone Grafts Sinus Grafts
Dental Implants need enough bone in the right place to put an adequately sized implant where it is needed and have enough support for the tooth or bridge that is planned. If you do not have enough bone we may need to give you more bone. With advances on modern techniques, with the correct case selection this is now quite predicable. If further bone is required this may be added at the time of implant placement or sometimes must be completed before the implant is placed.
Dr Wellings will place the bone graft under sedation. There are many sorts of graft material that we can use, but your own blood supply will infuse into the graft and your own cells will use the graft as a scaffolding to build your own new bone structure to replace the graft! A sinus graft is a particular technique where Dr Wellings will create a small window in the thin bone beside the top back teeth. inside the hollow of your sinus (cheek bone) there is a thin membrane, a little like that found under an egg shell. Gently this is lifted and the bone substitute is placed into the newly created space between the membrane and the sinus. The window is closed and after six months the graft is converted into your own bone. This allow the dentist to then place bigger and better implants to support your crowns, your denture or bridgework. Mechanically this increased support will increase the load distribution and contribute to a greater chance of success.
This is similar in aim to a sinus graft. Where the back teeth were lost a long time ago and the bone that was around the teeth has shrunk, and you need to place dental implants where there is inadequate bone above the nerve. By moving the “cable” of the nerve of the lower jaw to the side, the bone below can be used also for implant placement to engage adequate bone volume.
Snap Fastener Denture and Bar Retained Bridge Solutions
When the option of a denture is not enough to meet your needs, one solution is to combine the denture with two or four dental implants.
Snap Fastener Option This can be done quite nicely on the lower arch especially, because the bone in the mandible is usually of good quality for dental implants. This concept still allows for removal of the denture for cleaning. Many patients find that this is enough to enhance their denture and make it manageable. The placement of two implants and fitting of two snap fasteners allows you lower denture to “click” onto the implants. This holds the denture firmly and gives better grip, retention and stability.
Fixed Bridge Option With four implants on the lower jaw or six on the upper, you can lock a fixed bridge made completely of high quality porcelain.
Removable Bridge Option In some cases we prefer to recommend a removable/fixed bridge. This is locked onto the implants all day and night but can be removed for easy cleaning once a day.
