Chapter 3 Composition of the AQB implant system
Team of AQB Implant Workshop Instructors
The AQB implants are largely divided into two classes, one-piece and two-piece. The one-piece type, as
can be deduced from its name, is the fusion of the part that is inserted into the jaw bone, and theabutment that acts as the interface between the superstructure and the fixture.
In contrast, in the two-piece type, the “fixture” or the root part that is buried into the jaw bone, and the“abutment” are constructed separately. To link these parts, a specialized screw is required.
With the AQB implant system, the process of implantation, except for implant placement, can be doneusing a single tool.

I. The structure of the one-piece type
There are two types of AQB one-piece implants, the standard, and the T-type. Each implant is given amodel number, which denotes the dimensions of the implants: the diameter, the length of the root, andthe length of the abutment (Fig. 4-3-1).

A. The structure of the standard one-piece typeThe one-piece standard type has 27 variations, arising from three different diameters, five root lengths,
and five different abutment lengths (Fig. 4-3-2)

B. The structure of the one-piece T-type
The one-piece T-type has 11 variations, arising from three different diameters, three root lengths, and twodifferent abutment lengths (Fig. 4-3-3)

II. The structure of the two-piece type
The two-piece AQB implant is constructed of a set of fixtures and abutments. There are six fixture
variations, arising from two different diameters and three root lengths. The abutment types can beseparated into six classes including straight, angled, and over-denture abutments, giving rise to 28
different types in the product lineup.
The fixture comes with a healing cap attached, and all of the abutments, with the exception of the healing
abutment, which is attached by a fixing screw (Fig. 4-3-4).
The characteristic of the two-piece AQB implant is the common usage of abutments. Excluding one type ofabutment (the multi-abutment φ4, ss-type) all of the others can be fixed with both φ4 and φ5 fixtures.
Furthermore, by differentiating the uses of healing caps and healing abutments, it is possible to use thesefor both two-piece, two-stage; and two-piece, one-stage methods.

A. The two-piece, one-stage method
This system is shown in Fig. 4-3-5. The healing abutment is used to cover the fixture after the first
operation, once the fixture is implanted into the jaw bone. Gingivoplasty is conducted at the same time asimplantation.

B. Two-piece, two-stage method
This system is shown in Fig. 4-3-6. Here, by covering the fixture with a healing cap, the implant can becompletely buried within the gum to give time for bone formation to occur. The secondary surgery is thesame as with the one-stage method.

III. The structure of the AQB implant prosthesis
The dental impression techniques differ for one-piece and two-piece AQB implants (Fig. 4-3-7). With
regards to the one-piece type, as the fixture and the abutment component are fixed, the methods ofprosthesis creation are limited.

A. The basic prosthesis of the one-piece typeThe dental impression techniques for one-piece type AQB implants are done in the manner similar to thatused for natural teeth.

B. The basic prosthesis of the Two-piece type
After initially mounting the abutment onto the fixture, the dental impression of the two-piece AQB
implant can also be done in a manner similar to that used for natural teeth.
It is possible to create an even more precise superstructure, by performing closed-tray or open-tray
techniques using the tools shown in Fig. 4-3-8.

IV. The characteristics of the AQB implant system
As is shown above, a good balance exists between one-piece and two-piece types to fulfill the various
needs of patients. With the one-piece type, rapid recovery of dental occlusion can be expected, and withthe two-piece type, a superstructure similar in appearance to that of the patient's own teeth can beconstructed. Most of the indispensable tools for surgery (drills, reamers) can be used for both types; it istherefore possible to choose to implant either system with the least amount of expenditure.
Patients' expectations of implant treatment are rising. With the wide range of treatment options
available with AQB implants, each overcoming the faults of the other, it has become possible to meet therising demands of both dentists and patients.
