Study on OsseoSpeed™ TX Implants in the Upper Jaw in a Chinese Population

Not Applicable

Completed

• Conditions: Partially Edentulous Jaw

• Registration Number: NCT01389245
• Lead Sponsor: Dentsply Sirona Implants and Consumables

Brief Summary

The purpose of this study is to investigate the clinical efficacy of OsseoSpeed™ TX implants in a Chinese population by evaluation of marginal bone level alteration, implant stability and implant survival in the posterior maxilla up to 3 years after loading. Hypothesis: Early loading of the posterior maxilla is a safe and predictable procedure.

Primary Outcome Measures

Name	Time	Method
Marginal Bone Level Alteration	Measured at implant loading and 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).

Secondary Outcome Measures

Name	Time	Method
Evaluation of the Periimplant Mucosa Condition - By Assessment of PPD	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.
Number of Survived Implants	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.
Presence of Plaque	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-year follow-up visit after implant loading.
Number of Stable Implants	Measured at the 3-year follow-up after implant loading.	Implant stability evaluated clinically/manually (recorded as stable yes/no).
