3. Desirable criteria of Dental Implant Systems
• Simple and reliable
• Minimum components with maximum flexibility
• Can use for all indications and all positions of
mouth
• Ideal for one-stage and two-stage surgery
• Suitable for immediate and early loading
• The restorative options cover cement-, screw-
and attachment- retained solutions

4. OsseoSpeed
Microthread
Conical Seal Design
Connective Contour

5. Evolution through science –
ASTRA TECH Implant System™ EV
• OsseoSpeed — more bone more rapidly
• MicroThread — biomechanical bone stimulation
• Conical Seal Design — a strong and stable fit
• Connective Contour — increased soft tissue
contact zone and volume
EV & TX

6. Design- ISO 14801:2007
• ASTRA TECH Implant System EV is based on
the natural dentition utilizing a site-specific,
crown-down approach
• are designed to meet the requirements for
mechanical integrity, bone quantity, load
carrying capacity and biological response

7. Material selection ,design considerations
• produced from commercially pure
titanium (Grade 4) according to
requirements for dental implants (ISO
ASTM 67) for ensuring biocompatibility
• Then, the material is cold worked

8. The fatigue testing method consists of applying
a 30° off-axis load to an implant-abutment pillar
Each implant diameter survives five million load cycles

9. • the fatigue of the implant abutment and
abutment-cylinder interface, uses a 90° off-axis
load application.
• The strength index is based on the survival load
at 100,000 cycles using a Wöhler diagram
Methods for mechanical integrity testing

10. • Test setup per ISO 14801:2007.
The OsseoSpeed Profile EV
implant – abutment
assemblies were tested at a
30° angle with the implant
embedded to a level 3 mm
below the implant shoulder
(i.e., nominal bone level).
• A hemispherical test cap
(C) was placed on top of
the abutment to ensure
proper load (F) distribution.

11. Leakage testing of Conical Seal Design
NaCl Solution, drill hole at the bottom of
the implant. Fluid leakage can be detected
through a rise of the fluid column “X’

43. Implants of 6 mm vs. 11 mm lengths in the
posterior maxilla and mandible: a 1-year
multicenter randomized controlled trial
Authors: Gulje F, Abrahamsson I, Chen S, et al.
Published in: Clin Oral Implants Res 2013;24(12):1325-31.
• 95 patients, OsseoSpeed ,1-Stage surgery
• 4 x6 mm (49 pat, 107), 4 x 11mm (46pat, 101)
• Loading- 48 days , 20 H UniAbutments
• Follow-up- 1, 6, 12 months
• Assessment- Plaque occurance, probing depths,
bleeding on probing, peri-implant bone changes,
crown height and adverse events

44. Results 6mm 11mm
1yr Survival 97% 99%
Marginal bone gain 0.06mm 0.02mm
Bleeding, Plaque,
Probing depth
No significant different
Adverse events 6 abut screw, 4 healing cap loose, 2# pro:
crown, 3 fixed restorations loose
Conclusion 6 mm long implants is as favorable as when
treating patients with 11 mm long implants in
the posterior region when there is a sufficient
bone height

45. Clinical and radiographic evaluation of early loaded
narrow-diameter implants: 3 years follow-up
Authors: Maiorana C, King P, Quaas S, et al.
Published in: Clin Oral Implants Res 2015;26(1):77-82.
• 3.0mm in Upper Lateral and lower incisal positions
• One-stage and early loading
• OsseoSpeed TX = 3.0x 11 &15mm, 69 pats, 97 implants
• 6-10 weeks, individual modified TiDesign Abut, Metal-
Ceramic or all- ceramic single crown
• Follow up - 6, 12, 36 months
• Check- PPD, BoP, Gingival Zenith Score ( Mid incisal
edge to buccal gingiva), Intra-oral X ray, Marginal Bone
Level changes- Implant mean value was calculated….

46. Result 11 mm 15 mm
3yrs survival 95.5% 100%
Marginal bone

Mean: O.33 mm
Bleeding, Plaque,
Probing depth
No significant different
Adverse event 4 lost in early healing phase,
(early loading)
Conclusion OsseoSpeed TX 3.0S is a safe and
predictable treatment option where
space is limited in the anterior

47. Soft and hard tissue alterations around
implants placed in an alveolar ridge with a
sloped configuration
Authors: Noelken R, Donati M, Fiorellini J, et al.
Published in: Clin Oral Implants Res 2014;25(1):3-9.
• Healing around OsseoSpeed Profile implants
resulted in only small hard and soft tissue
alterations
• Moreover, the discrepancy between the
lingual and buccal bone levels were preserved

48. Randomized controlled multi-centre study
comparing short dental implants (6 mm) versus
longer dental implants (11–15 mm) in combination
with sinus floor elevation procedures.
Part 1: Demographics and patient- reported
outcomes at 1 year of loading
are viable treatments, rendering high implant survival
rates. Short implants may however be considered as
the more favorable treatment option with less short-
term patient morbidity, shorter treatment time as well
as lower cost
