TWO-STAGE PLACEMENT

Spiekermann: Color atlas of implantology

ONE -STAGE PLACEMENT

Fixture placement and abutment connection

in same time – immediate function

Spiekermann: Color atlas of implantology9

Time aspect of implantation:

• Immediately or only a few days after extr.

Immediate implantation

• 4-8 weeks after extraction

Delayed implantation

• 3-4 months after extraction

Early implantation

• At least 6 moths after extraction

Late implantation Prof. Divinyi

SINGLE TOOTH LOSS

differential therapy

1. Orthodontic space closure

Advantages:

- definitive treatments results

- essentially risk-free

Disadvantages:

- limited spectrum of indication

- associated esthetic difficulties

- length of treatment

- functional difficulties

SINGLE TOOTH LOSS


2. Maryland bridge

Advantages:

- no surgery required

- risk-free treatment

- good esthetics can be achieved

Disadvantages:

- preparation is necessary

- not possible in dentition

- reduced retentive surface

- risk of caries

SINGLE TOOTH LOSS


3. Conventional bridge

Advantages:

- no surgery required

- good esthetics can be achieved

- no time-consuming

Disadvantages:

- preparation is necessary

- pulp explosure

- risk of caries

- not possible in dentition

- irreversible

SINGLE TOOTH LOSS


4. Single tooth implants

Advantages:

- high success rates (better than 97% for 10 years)

- decreased risk of caries

- decreased risk of endodontic problems

- improved hygiene

- psychological advantage

- decreased abutment loss

IMPLANT BODY REGIONS

K. Pandya, R. Parikh, P. Pareek

IMPLANT BODY REGIONS

Body

- designed for implant bone interface

Crest module

- designed to retain the prosthetic component

- transition zone from implant body design to transosteal region at

the crest of the ridge

- has a platform on which abutment is seated

- when it is a smooth and polished metal – cervical collar


abutment

Implant body

prosthesis

superstructure

Prosthetic Attachment

Abutment

portion of the implant that supports or retains a prosthesis

or implant superstructure

Mezostructure

metal framework that attaches to the implant abutment

and provides either retention for removable prosthesis

or framework for fixed prosthesis


mezostructure

TYPES OF IMPLANT

ABUTMENTS

Screw retention

Cement retention Attachments

for RPD

PARTS OF IMPLANT –

SCREW RETAINED

Abutment

Abutment screw

Retaining screw

Composite resin

Implant body

PROSTHETIC RETAINED

SCREW

• can have a slot or hex head

• access is usually covered by a

combination of gutta percha (cotton

pellet or silicone) and composite.

• used to retain the prosthesis to the

abutment.
