One piece VS Multiple piece Implant
It is understood that one-piece implant design is a stronger concept as there is no connection between implant and abutment. The absence of a microgap can lead to minimal peri-implant bone loss. Furthermore, there is a reduction of mechanical complications such as screw loosening and abutment fractures. These implants can be immediately placed and can be put through instant function because of their high cortical stabilization. This immediate function protocol has advantages over two-stage surgical placement. Other benefits are fewer surgical appointments, reduced treatment time, and minimal trauma. It is suggested that one-piece implant can be an alternative to conventional implants for edentulous arches where there is a resorbed bone in width and height. Initially, one-piece implants were used as transitional or provisional implants. However, because of biological osseointegration, their removal often became difficult. Several manufacturers obtained approval for its use in defined situations. Proper treatment planning avoided comorbidity associated with augmentation procedures and acceptable esthetic result was achieved.Durrani, F., Nahid, R., Pandey, S., Singh, P., & Pandey, A. (2021).

Advantages of Single Piece Implants / One piece Implants (OPI)
Mechanical durability:The OPI possesses lot more mechanical durability since , the implant cross section is strong as compared to Two piece implants(TPI) .As there is certainly removal of abutment screw in OPI , there is absolutely no empty space in the implant that provides adequate sturdiness to OPI even though the smaller diameter as compared to Two piece implants(TPI).
-
Marginal bone loss: One piece implant demonstrates minimized minimal bone damage since it does not have any microgap between implant and abutment. Thus the lack of alveolar bone around the implants is reduced because it is unable to have bacteria. Researcher Hermann JS, Broggini N, and Archie A. Jones came to the conclusion that the one piece implant system does not have any micro-gap thereby will not show bacterial colonization at the FAI (fixture abutment interphase ) and also little initial bone resorption as compared to the two piece system.
-
In OPI there is no requirement of multiple surgical procedure and reduced number of prosthetic components like abutments, implants analogs and impression coping are needed.
-
Abutment screw doesn’t loosen or fracture.
-
A specialist can control the crown margins, the gingival contours and the angulations of the crown preparation with a bur in a quick and easy way.
-
One-piece design reduces secondary component placement, by this it saves a lot of time and improved soft tissue apposition.
-
They provide fast & painless replacement of missing teeth
PROBLEMS OF ONE PIECE IMPLANTS
-
Abutments cannot be customised because the companies manufactures the implants, hence customization is impossible.
-
The abutment milling needs to becarried outstraight in the oral cavity itself. This results in lot off stress on the implant which affects the treatment of the bone around the implant.
-
In some cases it may happen that the bone availability or bone thickness may be less.
-
OPI is very thin implants as compared to two piece implants.
-
OPI implants are very thin hence we need to place more number of implants.
-
Abutments will not have a finish margin. There will not be finish margin as the abutment is thin, so we cannot refine it more in the patient’s mouth.
This mayresult inlarge amount of food lodgement in a period of many years making it close to impossible to thoroughly clean and also preserve oral hygiene in these cases.
-
As crowns are made manually, we cannot use CAD CAM software for single piece implants. Therefore we can never give precision in these implants.
CONCLUSION:Implant therapy is recognized as a reliable treatment to replace missing teeth; however, proper surgical placement of dental implant is necessary to obtain the required esthetic result. Through proper treatment the correct position and number of implants be determined. The field of implantology is continuously evolving and one-piece implants are becoming popular. One-piece implant design have high cumulative implant survival rate as well as beneficial marginal bone levels.
The goal of modern implant therapy entails more than just the successful osseointegration of the implant. Osseointegration being an accepted and well documented concept and now being established scientific phenomena is directed towards improving the design of implants, simplifying the surgical protocol, immediate placement and loading of the implants, and to reduce the restoration time. The design of an implant plays a key role in the success of a final restoration. The two basic designs which are available are the two piece implant design and the one piece implant design. This one piece implant design was originally created to eliminate the structural weakness built into the two-piece implant design (micro gap). This review of the literature will outline the advantages and disadvantages, indications, contraindications, implant design, surgical and prosthetic phase, as well as some of the bio-mechanical parameters which are required for its selection.
ADVANTAGES OF ONE PIECE IMPLANTS
-
Mechanical strength:The OPI has more mechanical strength because, the implant cross section is solid as compared to TPI14.As there is elimination of abutment screw in OPI , there is no empty space in the implant which provides sufficient strength to OPI despite of its smaller diameter as compared to TPI11,9.
-
Marginal bone loss: OPI shows reduced marginal bone loss as it has no microgap between implant and the abutment. Thus the loss of alveolar bone around the implants is minimized as it cannot harbor bacteria. Hermann JS et al15, Broggini N et al16, and Archie A. Jones et al17 concluded that the one piece implant system has no micro-gap and therefore does not display bacterial colonization at the FAI (fixture abutment interphase) and minimal early bone resorption when compared to the two piece system
-
OPI reduces the requirement of multiple surgical procedures and prosthetic components thereby reducing inventory (abutments, impression copings, implant analogs etc.) & cost.18
-
No loosening or fracture of the abutment screw (healing abutment or prosthetic abutment).12
-
The clinician can control the final crown margins, the gingival contours and the angulation of the crown preparation with a bur in a quick and easy manner.18
-
The OPI follows the conventional crown and bridge procedure (preparation, temporization, impression and cementation).18
-
One-piece design eliminates secondary component placement, saving time and improving soft tissue apposition

One piece implantology after wide spread diffusion in the second half of the last century saw its application significantly reduced by dental implantologists. The main reason of a progressive reduction was the Brakeman concept of implant Osseo integration, although now the most recent knowledge allows reducing the timing on implant loading. Another significant factor is attributable to the prosthetic difficulties compared to two-pieces devices and to the technological limits that have made the one piece implants not suitable for the paradigms of modern implantology. The intent of the authors is to repropose one piece implantology and highlight the use of medical devices designed and built in the past, but contextualized currently in light of the technological improvements available today so that they can be considered as a valid alternative to the others implant methods.
