Eligibility Criteria

Inclusion Criteria

  • male and female patients 18 years to 80 years of age
  • no general medical condition which represents a contraindication to implant treatment
  • two adjacent missing teeth in the maxilla or mandible in positions of premolars and molars
  • at least one tooth present adjacent to the edentulous space
  • indication for implant treatment is given
  • at least 8 mm of vertical bone height in the mandible allowing for the placement of a 6 mm implant (2 mm safety distance to inferior alveolar nerve)
  • at least 4 mm of vertical bone height in the maxilla
  • signed informed consent after being informed

Exclusion Criteria

  • smoking of more than 15 cigarettes a day (clinical studies show an increased failure rate of implants in heavy smokers)
  • poor oral hygiene after hygienic phase (Plaque Index over 30 %)
  • active periodontal disease
  • pregnancy or breastfeeding at date of inclusion

Outcomes

Primary Outcomes

radiographic bone level

Time Frame: 5 years

The primary endpoint of the study is the radiographic bone level 5 years after insertion.The bone level represents an indicator of the osseointegration and biological success of the implant.

Secondary Outcomes

  • Radiographic bone level(1, 3, 7, 10 years)
  • rate of technical complication(1, 3, 5, 7, 10 years)
  • rate of biological complications(1, 3, 5, 7, 10 years)
  • Soft tissue changes(1, 3, 5, 7, 10 years)
  • Implant survival and success(1, 3, 5, 7, 10 years)
  • Patient morbidity(1, 3, 5, 7, 10 years)
