Implants

 

We have over thirty years experience with Osseointegrated Implants and are familiar with all major, and most other Implant systems.

We are a Straumann Platinum Approved Laboratory and are members of the International Team for Implantology (ITI)          and the ADI

We offer a full planning service including Diagnostic Wax-ups, Surgical and Radiographic Stents, Jigs, Articulations, Bite Registration and Provisional Restorations.

We consider planning to be the key to a successful outcome and are happy to discuss any case before and during restoration.

Screw Retained Restorations

These are becoming the most popular form of Implant restoration as they are retrievable for maintenance and are also easier to fit, as they are without the soft tissue problems associated with cement retained restorations. However, correct fixture alignment is critical to avoid screw channels exiting through the aesthetic surface of restoration.

Fortunately there are a few compatible systems which allow the angling of screw channels (details below)

CAD CAM

These abutments are designed using a Dental Scanner and can be manufactured in non-precious alloy, Titanium and Zirconia. These are then fitted with a monolithic crown unit or bonded .

Cast-on Non Precious Alloy

These are generally made using compatible components, as most of the major implant companies do not provide a cast-to abutment for non-precious alloy. Porcelain is then bonded directly to the cast abutment or can be used as a hybrid resoration using monolithic

zirconia or lithium disilicate.

Cast-on Precious Alloy

These are made using original components from Implant Companies. They are more expensive as the components are manufactured using precious alloy and the cost of cast-on alloy is high.

 

Transmucosal Abutments

These are used mainly for bridges where fixtures are deeply placed or at an unsuitable
angle for direct connection. They are used to raise the height of the fixture and convert to an external connection. This allows greater angles to be accommodated. Some are also available for angle correction. They also allow non precious alloy to be used, utilising original components.

 

 

Hybrid

These are the most cost effective restorations. They involve using a Titanium abutment, such as VarioBase from Straumann and then making a Crown with a screw channel through the middle. The Crown, which can be made of various materials, such as

Porcelain fused to metal, Emax, Zirconia or composite, is then cemented on to the base making a one-piece screw retained restoration. They are very useful for Bridges as due to the cement layer they are completely passive.

Angled Screw Channel

These are very useful restorations if the angle of the fixture is not at its optimum position.

They require the use of a specialised screw driver which enables the screw to be tightened at an angle of up to 25 degrees.

These use compatible components and can be manufactured by either cast-on or CADCAM and can be made in non precious alloy, Titanium or Zirconia. This system is also available for Bridges using CADCAM technology.

 

Cement Retained Restorations

These restorations are especially useful when angles of abutments need to be drastically modified. It is necessary to ensure that all traces of cement are removed on fitting as they can affect the soft tissue. We would generally place the Crown/abutment margin at a maximum of 1.5-2mm below the gingival margin to ensure easier removal of cement.

Cement retained crowns and bridges can be made on several different types of abutments

Stock Abutment

These involve using a stock abutment which can be modified in the Laboratory and the Crown made using various materials.

 

Custom Abutment

These are used when a stock abutment cannot be used and involve waxing and casting onto a castable component.

CAD CAM Abutment

These are designed using a Dental Scanner and are then milled in non-precious Titanium or Zirconia.
