Comparison of Two/Three Piece & Single Piece Dental Implants

Considerations Single Piece Implants Two – Three Piece Implants
Basic design The implant and the abutment are fused – they are manufactured as one piece 

 

The implant and the abutment are separate. The abutment is either cemented or cold welded. If the abutment is secured with a screw onto the implant, then it can be considered to be three piece.

 

Implant Placement Procedures Single sitting surgical procedure and very often flapless (no open surgical procedures are necessary). Implant procedures are less time consuming than that required for bridgework. Very often more complex surgical procedures are necessary, spread over 2 or 3 sittings in a period of 3-6 months (Implant placement, Healing Screw placement & Abutment Placement)
Loading Immediate Loading  – ie patient can be given the crown(s) / bridge(s) the very next day Delayed Loading – very often a waiting period of minimum of 3 months is necessary before loading the implants with prosthesis.
Prosthodontic Procedures Conventional impressions of the implants can be made just as is the case with conventional bridgework. Less time consuming. Requires more complex procedures and is more time consuming.
Sizes & Designs A wide range of sizes and designs are available suiting various bone types and measurements. The designs even help avoid bone augmentation and sinus lifts. Limited sizes and designs are available thereby limiting their application
Cost These work out a lot more cost effective in comparison with two/three piece implants Expensive – with respect to the costs of the implants as well as the time taken for multiple procedures
From the patient’s point of view Less complex placement procedure, less number of sittings and crown(s) & bridges can be cemented in a day or two… more or less like that of a conventional bridgework & costs are comparable with that of conventional bridgework More complex placement procedure involving two or more surgical phases. Crowns / bridges are cemented only after 3 months after the healing phase. Much more expensive than the conventional bridgework.
Long term maintenance Being a single piece, the strength provided by the implant is excellent and there is no separate root portion and abutment portion. Maintenance is very simple… maintenance is just the same as that of conventional bridgework Being two piece, the relation between the root portion and the abutment portion can present problems. Studies have proved that two piece implants experience higher mechanical stress under oblique loading. Maintenance of these implants are more complex… very often screws (when used) are to be tightened at periodic intervals as there will be micro-movement between the implant and the abutment.
However, it is to be kept in mind that KOS Single piece implants are not indicated in all cases & they are to be used only in cases where there is good D1 / D2 bone.KOS Implants are approved by the European Union and due to be approved by the US-FDA shortly.
