Introduction

This paper intends to explore the concept of Angled abutment. Further, three methods are discussed, namely. Prefabricated angled abutments, Cast abutments (e.g. UCLA) and Milled abutments (e.g. Procera). In addition, merits of these methods are also discussed. During the past several decades, there has been a significant increase in the number of dental implant manufacturers and implant restorative components available for clinicians and dental laboratory technicians treating partially edentulous patients. While the increase in components has improved the esthetic and functional results obtainable with dental implants, clinicians also have reported difficulties and confusion in treatment planning dental implant restorations for partially edentulous patients. This paper introduces a protocol for implant abutment selection undergoing dental implant treatment, their merits for abutment selection in implant dentistry for implant surgeons, restorative dentists, and dental laboratory technicians.

Discussion

Prefabricated angled abutments

It is used for single or multiple restorations (feruladas). Margins prefabricated eliminate the need for further preparation of the column and allow obtaining correct gingival contours. You can take direct prints on the Pillars COC using conventional printing techniques UCLA for the impression and the work of abutment preparation and manufacture of the crown belongs to the dental laboratory. It requires an abutment screw gold or titanium.

During the healing of dental implants are fixed firmly to the jawbone. Healing takes about 4 months in the mandible and 6 months - on the upper jaw. The difference in the length of time periods for the healing of the bone tissue of the upper and lower jaws due to the different properties of bone.

The operation is the most simple and takes 30 minutes. At this stage, mucous forming around the implant, ie, involved in the aesthetics of the gums - dentogingival form papillae. After 2-3 weeks of starting to prosthetics.

The doctor makes the imprint establishes the abutment, which together with the implant provides support for the future of the prosthesis (crowns, dentures).

Advantage of ready-made titanium abutments:

Less expensive than individually manufactured abutments (UCLA, Procera, etc.)

profile and be individualized to fit Emergence

robust and wear

lowest risk of allergies Disadvantage assembled titanium abutments:

partly aesthetic problems associated with all-ceramic crowns possible

Edge of the abutment shoulder is high scalloped gingiva morphotype (very thin Ginigiva) to shine through

not applicable in all cases (extreme implant inclinations, telescopic superstructures, certain glands) Advantage assembled zirconium abutments:

Ceramic use directly

excellent esthetics (translucency comes in, light refraction and light absorption of the natural tooth to the next)

smallest plaque retention

Hypoallergenic

Individualizer bar (such as titanium abutments, however, required because of breakage more residual strength) Disadvantage assembled zirconium abutments:

increased risk of fracture

limited range of indications

very expensive

Features of Prefabricated Angled Abutments

Very high stability

High chewing comfort

Reduced prosthetic base

Improved phonetics

Optimal hygienic capability

Cast abutments (e.g. UCLA)

ULCA GoldAdapt and abutments consist of a prefabricated base, which is screwed onto the implant and a angussfähigem top which can be customized. For the individual design of the upper part are on the abutment plastic cylinders arranged which is shortened by means of wax ...
