Retrospective Study

121 ZV3 (Patent™) Implants in 74 consecutively treated patients over 3 years

In partially edentulous patients endosseous zirconia implants offer 3-year survival rates similar to that of titanium implants, with healthy and stable soft and hard tissues.

Key Take Aways:

  • 96,5% survival rate over 3 years
  • Implants placed immediately or delayed
  • PPDs of 1.8 ± 0.4 mm and mean
    BOP scores (4.1% ± 4.2%)
  • Significantly lower PPD and BOP around
    implants than around teeth
  • Stable marginal bone levels (mean bone
    loss of 0.1 ± 0.6 mm after 3 years)

Retrospective Study

91 Patent™ Implants in 39 patients over
5 - 12 years of function

Endosseous zirconia implants can be used in compromised patients with little biological complications over the long term.

Key Take Aways:

  • Compromised patients
    (systemic disease, heavy smokers,
    periodontitis, medication)
  • Implants placed immediately or delayed
    (with immediate or delayed loading).
  • Bone grafting was performed when needed
  • No peri-implantitis according to current
    definitions (Berglund et al.)
  • No progressive bone loss
  • 8 implants showed bone loss of 3 mm
    (correlated with too deep implant placement)
  • 3 implants showed periimplant mucositis,
    no pockets around the other implants

Prospective Study

52 ZV3 (Patent™) two-piece Implants for single tooth replacements over 2 years

Within the limitations of a prospective cohort study, it was concluded that this two-piece zirconia implant with its glass fiber abutment can be successfully used in the clinical indication investigated.

Key Take Aways:

  • 95,8% survival rate
  • Internal sinus lifts and simultaneous
    grafting of buccal dehiscences,
    when necessary
  • Implant failure significantly correlated
    to oral surgeon
  • No implant fractures
  • All implant sites showed an increase
    of the vestibular mucosal level and a
    gain of keratinized tissue at 24 months

Prospective Study

52 ZV3 (Patent™) two-piece Implants for single-tooth replacements over 9 years

In the 9-year follow-up study it was concluded that with the two-piece zirconia implant system investigated, long-term successful, reliable and esthetic restorations can be achieved.

Key Take Aways:

  • 94,1% survival rate
  • 1 implant lost after 110 months
  • No implant fractures
  • PI, BoP and PD unchanged between
    2- and 9-year follow-up
  • 13% BoP
  • 55% of patients showed no BoP
  • Only two patients showed 50% BoP
  • PPD of 3 mm
  • Stable tissue levels after 9 years
    (MR <1mm for all implants)

Preclinical Study

in the Miniature Pig Mandible

Patent™ Implants offer superior osseointegration speed and success, and a favorable soft-tissue response similar to natural teeth.

Key Take Aways:

  • Bone-Implant Contact (BIC) of over 70
    after 4 weeks of healing (over 80%
    after 8 weeks of healing)
  • Highly rough implant surface contributes
    to rapid bone formation and osseointegration
  • Despite non-existent oral hygiene, only one 
    Implant showed slight signs of inflammation
  • Beneficial and firm soft-tissue adaptation
    was observed around the Patent™ Implants
  • Soft Tissue Seal remained consistently
    above soft-tissue level after 4 weeks of

Scientifically Proven
