A COMPARATIVE EVALUATION OF THE EFFECTS OF OZONATED WATER AND NORMAL SALINE IRRIGATION ON DENTAL IMPLANTS PLACED USING OSSIODENSIFICATION AND CONVENTIONAL DRILLING PROTOCOL- AN IN-VIVO STUDY

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, the sterilization protocol, which may come as a challenge to the implantologist. Implants placed in poor quality bone are often related to compromised stability and poor Osseointegration.

 Osseodensification technique, could increase primary stability of dental implantsin poor quality bone. This procedure is characterized by low plastic deformation ofbone 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 compactsand autografts the particulate bone in an outward direction to create theosteotomy, thereby preserving vital bone tissue and densifying the bone at the site.

 Ozone is known to react as an antioxidant, able to promote homeostasis, enhance local oxygen supply and elicit bactericidal effect particularly on staphylococcal and streptococcal infections. Previous literature has showed that ozone readily penetrates through the tissue, eliminates any bacterial, fungal and viral contamination.The application of ozone in oral surgery has an attempt to disinfect the oral cavity prior to surgery. Creating a sterile surgical environment in the oral cavity would be a desirable prerequisite for implant surgery. To get some way towards this goal, a sterile implant site is achieved by irrigating ozone water(25 μg/ml) during surgery. This would also promote healing and stimulate the immune system.

 Resonance frequency analysis (RFA) is a non-invasive technique that gives a clinical measure of stability and presumed osseointegration of the placed implant.Assessment of inflammation through inflammatory biomarker C-Reactive Protien(CRP) with Interpretation of CRP levels will be done one day before (preoperative) the implant placement and after 48 h (postoperative) of implant placement in both the groups

The experimental design consists of

Group A – Implants placed using conventional implant technique

·          Sub group 1- irrigation done using normal saline

·         Sub group 2- irrigation done using ozonated water(25 μg/ml)

 Group B – Implants placed using osseodensification technique

·         Sub group 3- irrigation done using normal saline

·         Sub group 4- irrigation done using ozonated water(25 μg/ml)

All the groups will be subjected to Resonance Frequency Analysis(RFA) to determine the implant stability quotient (ISQ) during Implant placement.

 The crestal bone loss of the groups will be radiographically determined at

1.      Implant placement

2.      After 6 months

3.      After 12 months
