Clinical Trial Summary

Deficient alveolar mandibular ridge corrected distraction osteogenesis to facilitate dental implant placement. Patients grouped into 2 groups: one group received Cissus quadrangularis during the consolidation period, and the other group received placebo.

Description:

OPGs were taken immediately after distractor placement, at end of activation period, at 1st,2nd month of consolidation period, and at end of consolidation period. Change in bone height was evaluated immediately after distractor placement, at end of activation and end of consolidation periods.

CBCT were taken immediately after implant installation, and 6 months later to evaluate change bone density and marginal bone level about the dental implant.

histological evaluation was done by biopsy obtained, by trephine bur, from implant site during its preparation. The bone biopsy fixed in 4% formalin solution for 7 days, rinsed in water, and dehydrated in sequent phases of ethanol (70, 80, 90, and 100%) and then specimens were stained by hematoxylin- eosin for microscopic evaluation.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Bone gain after distraction	Increase in bone height after distraction	immediately at end of distractor activation
Primary	Relapse after distraction	Relapse evaluated on panorama	3 months from beginning of consolidation period
Primary	Crestal bone loss around dental implant	By using cone beam CT, crestal bone level around implant evaluated by measuring a distance from implant apex to a point on dental implant where bone contacts the dental implant mesially and distally. then average of bone loss round each implant was obtained.	6 months from implant placement
Primary	Bone density around dental implant	By using cone beam CT, bone density assessed around dental implant at crestal, middle, and apical portions then average was obtained	6 months from implant placement
