Study on OsseoSpeed™ TX Narrow Implants in the Lower Jaw in a Chinese Population
October 7, 2019 updated by: Dentsply Sirona Implants and Consumables
An Open, Prospective, Multi-center Study to Evaluate OsseoSpeed™ TX Single Implant 3 mm Diameter in the Anterior Mandible. A 3-years Follow-up Study.
The purpose of this study is to investigate the clinical efficacy of OsseoSpeed™ TX 3mm diameter implant in a Chinese population by evaluation of marginal bone level alteration, implant stability and implant survival in the posterior mandible up to 3 years after loading.
Hypothesis: Early loading of the 3 mm implant is a safe and predictable procedure.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Number of Survived Implants
Time Frame: Measured at the 3 year follow-up after implant loading.
|
Implant survival rate evaluated by clinically and radiographically counting the number of implants remaining in function
|
Measured at the 3 year follow-up after implant loading.
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Marginal Bone Level Alteration
Time Frame: Measured at the 3 year follow-up after implant loading.
|
Marginal bone level determined from radiographs and expressed as the distance from a reference point on the implant to the most coronal bone-to-implant contact on the mesial and distal aspect of the implant.
Marginal bone level expressed in millimeters at the 3 year follow-up visit compared to values obtained at delivery of permanent restoration i.e. loading (baseline).
|
Measured at the 3 year follow-up after implant loading.
|
Number of Stable Implants
Time Frame: Measured at the 3 year follow-up after implant loading.
|
Implant stability evaluated clinically/manually (recorded as stable yes/no).
|
Measured at the 3 year follow-up after implant loading.
|
Evaluation of the Periimplant Mucosa Condition - By Assessment of PPD
Time Frame: Measured at the 3 year follow-up after implant loading.
|
Condition of the periimplant mucosa by assessment of probing pocket depth (PPD). Change in pocket depth expressed in millimeters at the 3-year follow-up visit, compared to values obtained at delivery of permanent restoration, i.e. loading (baseline). Negative value = increased pocket depth. |
Measured at the 3 year follow-up after implant loading.
|
Evaluation of the Periimplant Mucosa Condition - By Assessment of BoP
Time Frame: Measured at the 3 year follow-up after implant loading.
|
Condition of the periimplant mucosa by assessment of Bleeding on Probing (BoP).
Presented as % of implants that show presence of bleeding on probing at time of the 3-year follow-up visit.
|
Measured at the 3 year follow-up after implant loading.
|
Presence of Plaque
Time Frame: Measured at the 3 year follow-up after implant loading.
|
Occurence of plaque around the study implant.
Presented as number of implants that show presence of plaque at time of the 3 years follow-up visit after implant loading.
|
Measured at the 3 year follow-up after implant loading.
