Prospective Study of NanoTite Implants Placed Into Fresh Sinus-Lift Augmentation Sites (VSSL)
|ClinicalTrials.gov Identifier: NCT00713206|
Recruitment Status : Completed
First Posted : July 11, 2008
Results First Posted : October 11, 2013
Last Update Posted : August 30, 2017
This prospective, randomized-controlled, clinical study evaluates the ability of the NanoTite implant system to achieve integration and provide long-term support of a prosthesis when placed immediately in fresh sinus augmentation material. Control cases will be those where the sinus augmentation material is allowed four months of healing prior to NanoTite implant placement. In addition to implant performance, radiographic evidence of crestal bone regressive modeling will be used to evaluate differences between test and control cases.
Study (null) hypothesis: The implants placed into sinus augmentation sites at the time of grafting will have the same integration success and maintenance of integration as for the implants placed after four months of graft healing.
|Condition or disease||Intervention/treatment|
|Tooth Disease Partial Edentulism||Device: Dental Implant (Osseotite)|
This will be a prospective, randomized-controlled, longitudinal study in which qualified patients with partial edentulism and thin maxillary ridges will have as part of their treatment at least one sinus ridge augmentation procedure and have their edentulism restored with an implant-supported short-span or long-span fixed bridge. Each patient may have up to two cases included in the study should they need bilateral sinus augmentation using unilateral bridge restorations on either side.
Each patient (or side if a bilateral case) will be randomly assigned to one of two groups: Treatment Group 1 (test) cases will have implants placed into the sinus cavity during the graft augmentation procedure. Treatment Group 2 (control) will have a sinus lift augmentation and implant placement into this area will take place after four months of graft healing. For both groups the implants will be submerged and allowed four months of healing before second stage surgery.
