Trial Outcomes & Findings for A Study of Dental Implants Coated With Bone Morphogenetic Protein (NCT NCT00422279)

NCT ID: NCT00422279

Last Updated: 2016-04-20

Results Overview

The following success criteria for the primary endpoint have been adopted and apply to both treatment groups. 1.The implant stability (ISQ) was recorded by means of resonance frequency analysis (RFA) at implant insertion, 3 months and after 6 months of loading 2. radiographic and computed tomography analyses shall not show any signs of peri-implant radiolucency at the 3 and 6 month time point 3. implant stability after 3 months shall allow tightening to 35Ncm without implant rotation by using a torque wrench

PRIMARY outcome

Timeframe: Implant insertion, 3 months, 6 months

Population: Implant stability was measured using a torque wrench, Resonance frequency analysis was conducted, radiographs were analyzed and computed tomography was performed

SECONDARY outcome

Timeframe: 3 months

Population: 1.When implants were placed in the supraalveolar position the treatment was not successful 2. in the group where implants were placed in extraction sockets the treatment was not successful

The secondary endpoint of the study was to assess the minimum dose of rhBMP2 eliciting bone growth.The secondary endpoint was assessed by measuring using a probe the quantity of any newly formed bone 1.in the group where implants were placed in the supra alveolar position the treatment is successful if the bone exceeds 1.5 mm above the initial alveolar bone level in all measured points 1. in the group where implants were placed in extraction sockets the treatment is successful if the gap between the implant body and the extraction socket is filled with Bone. Safety dose used:- In the dog model; seroma formation was extensive with higher rhBMP-2 concentrations (3.0 and 4.0 mg/mL.Seromas was also significant in the dog model for the 0.75 and 1.5 mg/mL rhBMP-2 concentrations, hence a minimum dose of 15 and 30 µg per implants was chosen)
