Multicenter Study to Evaluate the Clinical Outcome of the OmniTaper EV Implant in Single Tooth Restorations
Study Details
Study Description
Brief Summary
This clinical study, funded by the company Dentsply Sirona, is being carried out to see if the newly developed tooth implant "OmniTaper EV" is safe, effective and functions as intended when replacing a lost or removed tooth. The OmniTaper EV implant is a further development of existing dental implants. It is made of titanium, a metal that is well tolerated by the human body, which has been successfully used in dental implants for more than 40 years. All components used in this study are available on the market, are CE-marked and will be used according to intended use and approved instructions.
The study involves at 11 planned clinic visits including follow-up visits 6 months and annually until 5 years after installation of the permanent crown. after over a period of about five and a half years. The treatment method and healing period may vary depending on the individual case and treatment plan and additional visits may therefore need to be scheduled. The visits and procedures are the same as standard of care and no procedures will be done just for purpose of research.
The study aims to recruit about 137 men and women from six clinics across Europe (Germany, UK and Switzerland) and participants can only receive one study implant each. Participation is entirely voluntary and participants can choose to withdraw from the study at any time, without giving a reason. The decision to decline or withdraw participation will not affect participants future treatment or care

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Single tooth restorations A single, open-label group with patients in need of single tooth restorations will receive an OmniTaper EV implant system available in the following sizes: diameter 3.4, 3.8, 4.5 and 5.5 mm and lengths 8, 9.5, 11, 13, 15 and 18 mm. |
Device: OmniTaper EV implants
Partially edentulous subjects in need of one implant in the maxilla or mandible (2nd and 3rd molars excluded) will receive an OmniTaper EV implant system. The study will be done in accordance with standard dental practice using a one- or two-stage surgical protocol and immediate or delayed placement and/or loading.

Outcome Measures
Primary Outcome Measures
- Implant survival rate 1 year after permanent restoration by counting implant in place 1 year after permanent restoration [1 year after permanent restoration (which is estimated to occur approximately 3 months after implant placement).]
Implant survival rate is a binary variable evaluated clinically, i.e. 'Yes' or 'No' where 'Yes' means that the implant is still in place and 'No' means that the implant is not in place. Any implant that has been removed or lost after implant placement visit will be considered a failure, whatever the reason for removal/loss.
Secondary Outcome Measures
- Implant survival rate at 3 and 5 years after permanent restoration by counting implant in place. [3 and 5 year after permanent restoration (which is estimated to occur approximately 3 months after implant placement).]
Implant survival rate is a binary variable evaluated clinically, i.e. 'Yes' or 'No' where 'Yes' means that the implant is still in place and 'No' means that the implant is not in place. Any implant that has been removed or lost after implant placement visit will be considered a failure, whatever the reason for removal/loss.
- Change of implant stability quotient value (ISQ) between implant placement and permanent restoration. [From date of implant placement (which is estimated to occur approximately 1 month after enrollment).]
Implant stability will be evaluated by ISQ value using Resonance Frequency Analysis (RFA). The stability is presented as an ISQ value. The higher the ISQ value the higher the stability. Recorded as a numeric value (1-100).
- Final and maximum insertion torque value for each implant at implant placement. [At date of implant placement (which is estimated to occur approximately 1 month after enrollment).]
Final and maximum insertion torque value (ITV), based on ITV curve, measured in Ncm.
- Surgeon's assessment of implant stability and confidence at implant placement for each implant. [Immediately after implant placement (which is estimated to occur approximately 1 month after enrollment).]
Numerical scale 1-10, where 1 = totally disagree with the statement, and 10 = totally agree with the statement. Statements to be evaluated by the surgeon: "The implant was guided into the prepared osteotomy", "The implant followed the prepared osteotomy", "The implant has a good primary stability". Each statement will be evaluated separately.
- Implant success, i.e., number of implants documented as successful at 1, 3 and 5 years after permanent restoration. [1, 2, 3 and 5 years after permanent restoration (which is estimated to occur approximately 3 months after implant placement).]
Successful implants counted, i.e. 'Yes' or 'No'. An implant will be considered successful if all of the following criteria are fulfilled: Implant in place. Lack of evidence of peri-implant radiolucency in X-ray. Less than 1mm vertical bone loss during first year after loading with permanent restoration and 0,2mm annually thereafter. Absence of persistent and/or irreversible signs and symptoms such as pain, infections, neuropathies, paresthesia, or violation of the mandibular canal.
- Maintenance of marginal bone levels (MBL). [At permanent restoration (which is estimated to occur approximately 3 months after implant placement) and at 1, 3 and 5 years after PR..]
The MBL change from permanent restoration compared to 1, 3, and 5 years. MBLs will be determined from X-rays, expressed as the distance from the implant reference point to the most coronal bone-to-implant contact on the mesial and distal side of the implant. The average will be calculated and compared for each evaluation period.
- PPD (Probing Pocket Depth) [At PR (which is estimated to occur approximately 3 months after implant placement) and at 1, 2, 3, 4 and 5 years after PR.]
PPD will be evaluated at four surfaces around the implant (mesial, distal, buccal and lingual), by using a periodontal probe. The distance from the mucosal margin to the bottom of the probe-able pocket will be measured in millimeter. PPD mean values will be calculated on an implant level for each visit. Changes over time will be analyzed.
- Bleeding on Probing (BoP) [At PR (which is estimated to occur approximately 3 months after implant placement) and at 1, 2, 3, 4 and 5 years after PR.]
BoP will be evaluated at four surfaces around the implant (mesial, distal, buccal and lingual), by using a periodontal probe. Bleeding will be recorded as presence or absence of bleeding when probing to the bottom of the pocket. The proportion of surfaces with presence of bleeding will be calculated and presented on an implant level for each visit.
- Plaque [6 months, 1, 2, 3, 4 and 5 years after PR (which is estimated to occur approximately 3 months after implant placement).]
Plaque will be recorded as presence or absence of plaque by visual inspection on four surfaces at each implant site.The proportion of surfaces with presence of plaque will be calculated and presented on an implant level for each visit.
- Occurrence of Adverse Events (AEs) [From date of implant placement (which is estimated to occur approximately 1 month after enrollment) up to 5 years after permanent restoration (which is estimated to occur approximately 3 months after implant placement).]
Continuously collected and reported AEs at each investigation visit from implant placement.
- Occurrence of Adverse Device Effects (ADEs) [From date of implant placement (which is estimated to occur approximately 1 month after enrollment) up to 5 years after permanent restoration (which is estimated to occur approximately 3 months after implant placement).]
Continuously collected and reported ADEs at each investigation visit from implant placement.
- Occurrence of Device Deficiencies (DDs) [From date of implant placement (which is estimated to occur approximately 1 month after enrollment) up to 5 years after permanent restoration (which is estimated to occur approximately 3 months after implant placement).]
Continuously collected and reported DDs at each investigation visit from implant placement.
