Teeth have been severely deteriorated or lost. Now we need to rebuild and/or replace.
Tooth Colour Restorations – even the most heavily deteriorated teeth can be rebuilt by either porcelain or composite restorations.
Crowns – Fabricated from varying materials, including porcelain with or without metal and non-metallic sub-structures and also gold. These restorations act like a ‘hard hat’ for the tooth that distributes the load over the entire tooth on biting, increasing the overall strength of the tooth. They are ideal over heavily restored and/or endodontically treated teeth due to their increased brittleness and risk of fracture.
The tooth is firstly reduced by 0.5mm to 2mm, depending on materials to make the crown, then impressions taken. A protective temporary restoration is placed while the crown is being made. The crown is fabricated, outside the mouth, on models made from the impressions, then subsequently cemented (glued) onto the prepared tooth on a follow-up appointment. The crown essentially replaces the tooth structure that was previously removed on preparation.
In areas where cosmetics is of high priority, a non-metallic ‘all porcelain’ restoration may be desired and fabricated with remarkable colour and life like accuracy. An aspect that is common to many porcelain restorations.
Bridges – restorations that are used to span a gap in your teeth. Their viability depends on the supporting teeth, number of missing teeth (span), and loading forces. The missing teeth are replaced by fabricated teeth (pontics) supported by neighbouring teeth on either side of the gap.
Fixed Bridges – essentially bridges where the replacement teeth (pontics) are attached to crowns and fabricated as one. In the same manner as crowns, neighbouring tooth/teeth are prepared; the bridge is fabricated then subsequently cemented on to the supporting teeth. They can be as small as two units (one crown plus one pontic) but generally the conventional method is crown + pontic/s + crown. Fixed bridges, like crowns, are fabricated indirectly (outside of the mouth) from similar materials. Our preference is for an all tooth coloured porcelain on zirconia (a strong, non-metallic, white coloured material) in areas requiring high cosmetics and strength.
Adhesive Bridges – In certain circumstances, a porcelain false tooth with extruding wings is directly bonded to the neighbouring teeth on their inside surface. In this procedure the missing tooth is required to be fabricated offsite and placed on a subsequent visit.
Composite Bridge – The missing tooth is fabricated entirely from tooth coloured composite resin and bonded directly to the neighbouring teeth on the same day in the one procedure
Implants – “your third set of teeth on request”
Implants are designed to simulate a natural tooth as closely as possible in appearance and function.
Implants can range from a single tooth to a full arch replacement. They can also be used to support and retain dentures.
They consist basically of 3 components.
The titanium implant– simulates the root portion of the tooth.
The abutment – the connector joining the crown to the implant. It forms the bulk internal portion of the crown of the tooth. Generally fabricated either titanium, gold alloy or from non-metallic zirconia for aesthetic areas.
The crown– the visible portion of the tooth. Generally fabricated from porcelain.
The procedure involves the surgical placement of a titanium implant in viable bone where teeth have been lost. The surgery is done under local, general anaesthesia or under sedation. The implant is left for 3 months whereby bone intimately adheres to the surface of the implant to create support and stability. Once integration is completed, impressions are taken. The abutment and crown is then fabricated and placed on top of the implant. The crown can be cemented on the abutment that has been screwed onto the implant or screwed along with the abutment.
A screw retained crown onto the implant is preferred as this gives the crown a degree of retrievability, should the colour require adjusting in future or porcelain fracture occurs.
Integration (bone acceptance) generally is a highly predictable aspect of dental implants. The main failures tend to be screw loosening or porcelain fractures. These complications can usually be addressed simply, especially if the implant crown and abutment have been screw retained. It is simply a matter of removing the filling of the access channel to get to the screw, unscrew the crown and abutment, adjust or repair, then screw back on and reseal access hole.
Little fuss, no anaesthesia and done in minimal time.
Is there pain or discomfort?
Most patients are pleasantly surprised to find that post-operative discomfort was less than expected. The surgical site is generally very localized and kept to a minimum. Should discomfort be experienced local analgesics and anti-inflammatories can be prescribed.
What is the success rate of implants?
Implants can be a lifelong treatment. Once you have been assessed as a suitable candidate. The long term success rate for implants can be as high as 95% depending on the area of placement and density of bone.
Generally fabricated over 4 appointments (impressions, bite, try-in and finish)
We will individually design and fabricate full dentures to suit your facial features and position teeth for maximum aesthetics/cosmetics. We are very happy to try and reproduce your previous smile or improve on it.
A “try-in” appointment is ideally arranged whereby your teeth are arranged in a wax try in giving you the opportunity to view your teeth within your mouth before being finalized in an acrylic base.
Denture retention/suction is usually the critical factor in successful dentures. Unfortunately retention can be influenced by a number of factors including the ridge height, surface area of fitting surface, level of existing bone, amount of saliva, consistency of saliva and medications. Thus retention may vary between individuals. We will endeavour to always maximize retention.
As a general rule, the retention of an upper full denture tends to be reasonable whereas a lower full denture tends to be more mobile as there is usually very little, if any suction.
Partial dentures – Removable false teeth supported and retained by existing viable natural teeth.
Chrome Cobalt metal partial dentures– acrylic or porcelain false teeth are fabricate and joined by a light weight, thin and strong metal framework that is kept to minimal visibility.
Acrylic partial dentures– acrylic or porcelain false teeth joined by a gum tissue coloured pink acrylic. Thicker than metal cr/co but more readily adjustable and easier to add on and repair.
Immediate dentures – be it full or partial removable dentures. Immediate dentures can be fabricated prior to removal of existing teeth so you have minimal to no period without teeth. Immediate dentures require relining 6 months later as gum tissue heals and supporting tissue shape changes.
