Current Primary Outcome Measures ICMJE |
Determination of Implant Stability with RFA [ Time Frame: 3 months ] Dental Implant stability is a measure of primary stability and secondary stability.The Implant stability can be perceived as a combination of Mechanical stability, which is the result of compressed bone holding the implant tightly in place (Primary Stability) and biological stability, which is the result of new bone cells forming at the site of the implant and resultant osseointegration(Secondary stability).The Implant Stability Quotient (ISQ) is a scale of measurement developed by Osstell device for use with the Resonance Frequency Analysis (RFA) method of measuring implant stability. The Implant Stability Quotient is a linear mapping from resonance frequency measured in kHz to the more clinically useful scale of 1-100 ISQ. The higher the ISQ, the more stable is the implant. The Implant stability is measured every fortnight for three months in 10 patients.The values on test side and control side are plotted on the graph and analysed.

Brief Summary | As Regenerative Medicine is the next level in medicinal sciences, the use of mesenchymal cells have become prevalent, Similarly now stem cells are being used in dental research as well in various clinical applications.This study aims to evaluate the overall effect of osseointegration by use of Allogenic Mesenchymal Stem cells while placing dental implants.Healthy subjects will be chosen and dental implants placed bilaterally one with standard surgical protocol and other with the use of Allogenic Mesenchymal Stem cells.The implant stability is checked using Resonance frequency analysis(RFA).The RFA values are statistically evaluated at various intervals and observations will be analysed on both test and control side. | ||||||||||||
Detailed Description | This study prospective single center study . A total of 10 patients are selected to be treated with dental implants for their bilaterally missing edentulous condition, which can be supported by either removable or fixed rehabilitation. The edentulous space can either be in maxilla or mandible. The study is performed at the Department of Implantology (Sri Sai College Of Dental Surgery and Research Center, Vikarabad, India). The study is approved by institutional ethics committee (IEC). MATERIAL AND METHODS
METHODS Clinical Procedure Pre-operative planning is based on clinical and radiographic examination. After thoroughly recording the case history. The following investigations will be done prior to implant placement surgery: CBCT, CBP, CT, BT, Hg%, RBS, Vital signs and other relevant investigations. If all the parameters fulfill the inclusion and exclusion criteria, the patient's impressions are made and study models poured. Intraoral and extraoral photographs are taken. The surgical guide is constructed on the diagnostic models.Stem cells are carried from stem cell bank to the Department of Implantology in a cryovial, safely placed in the special device, which contains dry ice, to maintain the viability of stem cells. Surgical Procedure On the day of surgery, the dental operatory is thoroughly fumigated and all the infection control protocols are followed.The participants will be receiving oral and written information about the study and shall be providing the informed consent along with photography and videography waiver consent. Antimicrobial prophylaxis (amoxicillin 1gm) and antihistamine prophylaxis (20mg cetirizine) orally 1 hour before surgery should be given to the patient. The universal precautions protocol is followed to protect yourself, the patients and the dental assistant.The patient is asked to rinse the Oral cavity with chlorhexidine gluconate solution (0.2%) for 1 minute before surgery. IMPLANT PLACEMENT ON THE CONTROL SIDE To standardized the protocol the patient's right side is selected as the control side and left side as the test side. The surgical procedure is carried out under local anesthesia containing 2% epinephrine with 1:100,000 epinephrine. The surgical guide is placed on the teeth and is used to mark the position of the implant with round drill till it hits the bone. Mucoperiosteal flaps were raised with mid crestal incision and intrasulcular incision extending to one tooth mesially and other teeth distally. After full thickness flap elevation, the osteotomy sites are prepared using the drilling sequence instructed by the manufacturer.The dental implants Nobel Biocare Replace select (4.3 *10mm size) 4.3mm diameter and 10mm length is selected and placed in the osteotomy site with IF of 40 Ncm.Before approximation of the flap, the primary stability of the implant is recorded with the ostell device, which has a transducer attached to the device and a magnetic attachment smart peg is attached to the implant with a plastic peg holder each implant is measured twice from two different angles,around 90 degrees and parallel to the crestal line.The two measurements buccolingually and mesiodistally are recorded and an average of both the values are taken.The measurements values are then transferred into implant stability quotient (ISQ) units, which are given on a scale of 1- 100, with 100 being the highest degree of stability and it works on the principle of resonance frequency analysis (RFA).The smart peg is removed and Healing abutments are placed over the dental implants. The flap is sutured monofilament sutures 4-0. IOPAR are taken with KKD Radiograph system, which standardizes the distance between the collimator and the IOPAR. IMPLANT PLACEMENT ON THE TEST SIDE To standardized the protocol the patient's left side is chosen as the test side.The surgical procedure is carried out under local anesthesia containing 2% epinephrine with 1:100,000 epinephrine. The surgical guide is placed on the teeth and is used to mark the position of the implant with round drill till it hits the bone. Mucoperiosteal flaps were raised with mid crestal incision and intrasulcular incision extending to one tooth mesially and another tooth distally. After full thickness flap elevation, the osteotomy sites are prepared using the drilling sequence instructed by the manufacturer. the stem cells are centrifuged in a sterile environment as per the instructions are given by the stem cell bank.(Thawing protocol )Human mesenchymal stem cells (hMSC) are primary cells which can be successfully used for infusion purpose.The following is the recommended protocol for thawing and infusion of these cells:Remove the Cryovial of stem cells from dry ice,defrost the vial containing stem cells by placing in between both the palms with constant, moderate agitation, until ice in the ampule is no longer visible,immediately disinfect the vial with 70% isopropanol.Working under laminar flow hood, open the vial and transfer the contents to a sterile 15ml centrifuge tube and centrifuge at 3500 RPM for 5 minutes. Decant the supernatant and to the pellet add 1 ml of saline.Mix properly and the cells are ready for infusion at the osteotomy site. Remove the contents in a sterile dappen dish and before infusion of stem cells at the osteotomy site the implant is dipped in the solution for 3 minutes so that the stem cells adhere to the titanium implant surface. The same dental surgeon performs all the cases. The dental implants Nobel Biocare Replace select (4.3 *10mm size) 4.3mm diameter and 10mm length is selected and placed in the osteotomy site with IF of 40 Ncm11.Before approximation of the flap, the primary stability of the implant is recorded with the ostell device, which has a transducer attached to the device and a magnetic attachment smart peg is attached to the implant with a plastic peg holder each implant is measured twice from two different angles,around 90 degrees and parallel to the crestal line.The two measurements buccolingually and mesiodistally are recorded and an average of both the values are taken.The measurements values are then transferred into implant stability quotient (ISQ) units, which are given on a scale of 1- 100, with 100 being the highest degree of stability and it works on the principle of resonance frequency analysis (RFA).The smart peg is removed and Healing abutments are placed over the dental implants. The flap is sutured monofilament sutures 4-0.IOPAR are taken with KKD radiograph system, which standardizes the distance between the collimator and the IOPAR. POST SURGICAL TREATMENT The patient is advised to take soft diet for one week and not to spit and rinse for the next 24 hours. Antibiotics, Antihistamines, and NSAIDs must be continued for 3 days. Postoperative edema if any must be controlled with corticosteroids. The sutures are removed one week postoperatively. Recall visits Weekly recall of the patient for 12 weeks for evaluation and recording of implant stability measurements with Ostell ISQ device. Patient safety measures are evaluated on every visit like unusual pain, swelling, allergic reaction, inflammation, outgrowth, vital signs, blood assay or any unspecific reactions should be noted down. The emergency contact number is provided to the patient to report any abnormal incidence immediately. The prosthetic part of the treatment is to be carried out after 3 months either with removable or fixed rehabilitation. Statistical analysis Descriptive statistics will be computed to summarize the data for its central tendency and dispersion. Two sample t-test will be applied to see the mean change in the outcome variable between experimental and control groups. Repeated measures of ANOVA are being applied to see the time changes between experimental and control groups. Where ever data is not following uniformity, either transforming the data or nonparametric statistical technique will be applied. The analysis will be performed using IBM SPSS Version 19.0. |
