Difference Between Single Piece and Two Piece Implants
The area of Dental implants has grown due to demand from patients for teeth in a single day or for immediate teeth. Implantology has the potential to give patients immediate teeth, something that was a fantasy about a decade ago. Nowadays, patients can go to an implant clinic and leave with a set fixed teeth that are attached to dental implants. Many techniques, such as teeth in one day, the teeth within an hour and so on. have led to a significant change in patients’ lives. Our method “Permanent teeth in 3 Days” is the latest technique that can give permanent teeth within three days. This is made possible by the use of Single-Piece Implants made to provide immediate teeth. Most patients can qualify to receive these latest generation implants, which are thought to be the most effective dental implants currently because the latest implants do not require expansion of bone and are relatively inexpensive dental implants.
| Sr. No. | Parameters | Single Piece Implant | Two Piece Implant |
| 1 | Consideration | 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 pieces. |
| 2 | Basic Design | Simple. No joint. Single peice. | Complex. Two parts joint by screw. |
| 3 | Implant placement procedure | 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). |
| 4 | 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 efore loading the implants with prosthesis. |
| 5 | Prosthodontic procedure | Conventional impressions of the implants can be made just as is the case with conventional bridgework. Less time consuming. | Conventional impressions of the implants can be made just as is the case with conventional bridgework. Less time consuming. |
| 6 | Size and Design | 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. |
| 7 | 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. |
| 8 | 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. | Crowns / bridges are cemented only after 3 months after the healing phase. Much more expensive than the conventional bridgework. |
| 9 | Screw Loosening | Absent. Since there is no seperate abutment- screw-implant assembly. |
Very common. 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. |
| 10 | 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. | 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. |
