Study Comparing OsseoSpeed™ Implants of Two Different Lengths in the Upper and Lower Posterior Jaw

7. maj 2020 opdateret af: Dentsply Sirona Implants and Consumables

An Open, Prospective, Randomized, Multi-center Study Comparing OsseoSpeed™ Implant 6 mm With OsseoSpeed™ Implant 11 mm in the Posterior Maxilla and Mandible. A 5-year Follow-up Study.

The purpose of this study is to see if OsseoSpeed™ implant 6 mm long is effective for rehabilitation of edentulism and if so, how it compares with OsseoSpeed™ implant 11 mm long. The primary hypothesis is that the alteration in bone level is equal in patients randomized to 6 mm as to patients randomized to 11 mm implants.

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Radiological Assessments of Marginal Bone Level Alteration
Tidsramme: Evaluated from implant installation to 5 years follow-up after implant placement

Marginal Bone Level determined from radiographs and expressed as the difference 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 5 year follow-up visit compared to values obtained at delivery of temporary restoration i.e. loading (baseline).

Positive value = bone gain, Negative value = bone loss.
Evaluated from implant installation to 5 years follow-up after implant placement

Evaluation of the Periimplant Mucosa Condition - By Assessment BoP
Tidsramme: Measured at the 5-year follow-up visit after loading
Condition of the periimplant mucosa by assessment of Bleeding on Probing (BoP). Presented as s count of implants that show presence of BoP.
Measured at the 5-year follow-up visit after loading
Evaluation of the Periimplant Mucosa Condition - By Assessment of Change in PPD
Tidsramme: Evaluated at implant loading and at the 5-year follow-up visit.

Condition of the periimplant mucosa by assessment of change in probing pocket depth (PPD).

Change in pocket depth expressed in millimeters at the 5-year follow-up visit, compared to values obtained at delivery of permanent restoration, i.e. loading (baseline).

Negative value = increased pocket depth.
Evaluated at implant loading and at the 5-year follow-up visit.
Presence of Plaque
Tidsramme: Evaluated at the 5-year follow-up visit after loading.

Presence of plaque was evaluated at four surfaces around each study position (mesial, facial, distal and lingual). Plaque was recorded as presence or absence of plaque by visual inspection.

A study position was considered as bleeding "yes" if at least one of the four surfaces around the implant showed presence of bleeding on probing.
Evaluated at the 5-year follow-up visit after loading.
