简要总结
Dental implants, in today’s world are considered one of the best alternatives for replacement of missing teeth, showing better results in esthetics and function. The success rate of dental implants depends largely on the quality of bone present, and the ridge, which may come as a challenge to the implantologist. Implants placed in poor quality bone are often related to compromised stability and poor Osseo- integration.
The Osseodensification technique, could increase primary stability of dental implant in poor quality bone. This procedure is characterized by low plastic deformation of bone that is created by rolling and sliding contact using a densifying bur (Densahâ„¢ burs) that is fluted such that OD does not excavate bone but simultaneously compact and autografts the particulate bone in an outward direction to create the osteotomy, thereby preserving vital bone tissue and densifying the bone at the site.
Bone is known to form under mechanical stresses. Implants loaded using the progressive loading technique, in which a temporary prosthesis is placed within 48 hours at infra-occlusion and is then adjusted at regular intervals to increase the height of the prosthesis until it is eventually brought into occlusion, has in this regard shown less peri implant bone loss and better implant success rate.
Resonance frequency analysis (RFA) is a non-invasive technique that gives a clinical measure of stability and presumed osseo-integraion of the placed implant.
The experimental design consists of
Group A – Implants placed using Osseodensification technique
· Sub group 1- Implants loaded using progressive loading protocol
· Sub group 2- Implants loaded using conventional loading protocol
Group B – Implants placed using conventional implant placement technique
· Sub group 3- Implants loaded using progressive loading protocol
· Sub group 4- Implants loaded using conventional loading protocol
All the groups will be subjected to Resonance Frequency Analysis(RFA) to determine the implant stability quotient (ISQ)at
1. Implant placement
2. After 6 months
3. After 12 months
The crestal bone loss of the groups will be radiographically determined at
1. Implant placement
2. After 6 months
3. After 12 months
