The design philosophy of the ASTRA TECH Implant System EVis based on the natural dentition utilizing a site-specic,crown-down approach supported by an intuitive surgicalprotocol and a simple prosthetic workow.

Multiple considerations are required for each individual tooth, such as thesupport needed for the nal restoration in the particular position, soft-tissuehealing, and implant design and size.

The illustration indicates the recommended implant sizes in relation to thenatural dentition, provided there is sufcient bone volume and space inrelation to adjacent dentition.

Implant size/tooth position Implant-abutment interfaceconnectionTheOsseoSpeed EV implant has a unique interface forone-position-only placement of ATLANTIS patient-specicabutments. The interface also allows for the exibility ofsix-position indexing of prefabricated abutments, while indfree abutments can be seated in any rotational position.

Introduction

The ASTRA TECH Implant System EV is designed to meetvarious clinical situations found in partially dentate andedentulous patients. It has been thoroughly investigated innumerous technical, experimental and prospective clinicalstudies, and the extensive research and documentation have yielded a simple, exible and reliable implant system that isclinically proven to maintain marginal bone levels. A varietyof prosthetic treatment options can be undertaken usingimplants as anchorage units.

There are several indications for overdenture treatment inconnection with implant treatment. Functional, esthetic,phonetic and hygienic requirements in certain clinicalsituations support the use of the overdenture as a treatmentoption. The presence of at least one implant in each quadrantof the jaw, combined with a suitable attachment system,makes overdenture treatment a viable alternative whentreating totally edentulous jaws.

Attachment-retained treatment in the lower jawIn the lower jaw, the installation of a xed bridge restorationis often possible; however, patients sometimes prefer to havean overdenture for reasons of economics. Clinical studies withthe ASTRA TECH Implant System show that the survival rate ofimplants in the lower jaw is the same for overdentures as forxed bridge restorations, regardless of the retaining system.The following protocol is recommended in the lower jaw:• Minimum 2 implants, splinted or non-splinted

Attachment-retained treatment in the upper jawIn the upper jaw, the clinical result and long-termpredictability is more dependent on the mode of implantsupport and the design of the denture. A prefabricated orcustomized bar, splinting four or more implants can help toensure equally good results as in the lower jaw.The following protocol is recommended in the upper jaw:• Minimum 4 implants, splinted

Motives for attachment-retained treatment • An unfavorable jaw relation which makes treatment with a

xed bridge restoration difcult• Esthetic problems, e.g. the need for lip support in the

upper jaw• Phonetic problems due to loss of alveolar bone in the

upper jaw• Patient dissatisfaction with removable denture due to oral

irritations and/or loss of bone for denture xation• A bridge option makes satisfactory oral hygiene impossible

or extremely difcult to achieve• Edentulous patients with a cleft palate• Economic constraints

Further factors to considerFactors which govern the planning of the overdenturetreatment are the number and length of the implants, togetherwith quality and quantity of the anchoring bone tissue.To ensure an optimized restorative treatment, make sure thatthe following conditions are met:• Parallel implants• Rigid bar connector without large distances between

implants• Appropriate length of extension bars, not too long• Adequate resilience of the mucosa; the mucosa should not

be too soft• Provide an even load on the mucosa when the prosthesis is

in function

The Locator Abutment provides long-term stability and easeof use. The low vertical height is ideal for the majority of alloverdenture patients. Cases with angulation problems andlimited occlusal space can be easily corrected using Locator.

Clinical application:• Fully edentulous situations in the mandible.• Taking into consideration clinical documentation

available, non-splinted Locator Abutment EVsolutions are recommended in the lower jaw only

Locator ™ Abutment EV

Abutment selection

Before abutment installation, remove thehealing abutment and register the soft tissueheight for proper selection of the permanentabutment. The appropriate height of theLocator Abutment EV is where the outerretention geometry is at a supra gingivalheight.Note: Healing Uni EV design supportsthe permanent Locator Abutment EVconguration and creates a matching softtissue contour.

Impression

• Firmly attach the Locator Abutment Pick-upon the Locator Abutments and check toensure that they are securely in place.

• Take the abutment-level impression in astandard or customized impression traywith an elastomeric impression material.

• Remove the impression once theimpression material has set.

• Verify that the impression is correct andsend it to the laboratory.

Clinical procedure

Installation

• Mount the Locator Abutment EV and theplastic holder/sleeve onto the driver, apart of the Locator Core Tool.

• Seat the Locator Abutment EV manually.• Use the Locator Driver EV in the restorative

Driver Handle EV with the TorqueWrench EV. Tighten the abutment torecommended torque (25 Ncm).

Model

• Firmly place the Locator Abutment Replicainto the Locator Abutment Pick-up in theimpression.

• Fabricate a master model in high-qualitystone material.

• Place the spacer over the head of eachLocator Abutment Replica, mimicking theresilient situation, and attach the LocatorProcessing Caps to the replicas.

Overdenture

• Fabricate the overdenture by curing thefemale part into the acrylic.

• Use a burr to remove excess acrylic, andpolish the overdenture base.• Remove the overdenture from the model

and discard the black processing insertsusing the Locator Insert Removal Tool,a part of the Locator Core Tool.

Final restoration

• Send the nal overdenture with theLocator Abutment inserts to the clinician.

• Place the preferred Locator inserts intothe metal housing (Processing Cap),using the Insert Seating Tool, a part ofthe Locator Core Tool.

Packaging pre-sterilizationThoroughly dry everything prior to the sterilization process

to prevent the risk of corrosion. Assemble the tray andre-position the drills and instruments using drill/letter numbers,where applicable. It is recommended to wrap the instrumentsand tray according to the sterilization wrap manufacturer’sinstructions. It is recommended to place the abutments,screws, and applicable products in a sterilization bag.Note: For US: Use FDA cleared sterilization bag and16 minutes dry time at the end of the steam sterilization cycle.

SterilizationSteam sterilization with a pre-vacuum cycle (134°C/275°Ffor 3 minutes).

Sterilization procedure for zirconiaproductsThe products should not be sterilized in a steam autoclave.The process can affect the mechanical properties of thematerial.

For ZirDesign abutment: Liquid Chemical Sterilization/High Level Disinfection is recommended.Note: For US: Dry heat (160°C/320°F for 4 hours) is therecommended procedure.For ATLANTIS abutment in zirconia: Dry heat (160°C/320°Ffor 4 hours) is the recommended procedure.

StorageThe products should be stored, in their package, in a dryplace, at normal temperature (18– 25°C/64–77°F). Use thesterilized components within the stated time period from thsterile bag manufacturer.Note: For maintenance and cleaning of Contra Angles andTorque Wrench EV, follow the manufacturer’s instructions.
